Abstract: Root distribution has a significant impact on soil moisture and nutrient uptake. It is time and effort consuming to measure root distribution, but it is easy to study root distribution by empirical functions. Soil column experiments in field were conducted to measure alfalfa root distribution. Empirical root distribution functions were compared with measured data, and they were respectively incorporated in the Hydrus-1D software to simulate soil water movement. Consequently, the applicability of empirical root distribution functions and the effect of empirical root distribution functions on soil moisture dynamic change were verified and analyzed by comparing of measured and simulated values of soil moisture. The results showed that the simulated values of root density by functions of fitting root distribution, Prasad distribution and Hoffman and van Genuchten distribution were coincide well with measured values below

Abstract: The power transmitting capacity of existing single range hydro-mechanical transmission cannot meet high power requirement of heavy duty vehicle. A new type of dual mode compound power split hydro-mechanical transmission was developed, based on the principle of input split and output split types of hydro-mechanical transmission (HMT). Qausi-steady state equations were provided with parameters of a certain vehicle. By the equations, the characteristics of speed ratio, output torque and the power flow were analyzed. The scheme took the advantages of both types of HMT, including good starting performance and power flow characteristics, and the wording range of hydraulic units were improved. It provides a platform for energy saving transmission and is of a promising future as well.

Abstract: In order to investigate the response relation model of stomatal conductance of rice leaves and related factors under water saving irrigation treatment, the field experiment was conducted in Kunshan experimental station of the State Key Laboratory of Hohai University in 2006. According to the observed data, the response relation of different factors and stomatal conductance of rice was analyzed. Leaf-air temperature difference was introduced to improve the original models, and two types of representative models were compared as well. The results indicated that the improved model taken into account of leaf-air temperature difference under the water saving irrigation condition had superior interpretive simulation ability than the original one. The improved stomatal conductance model by Jarvis had better simulation results than the one improved by Leuning-Ball. The improved Jarvis stomatal conductance model is recommended under water saving irrigation treatment.

Abstract: The method of projection pursuit (PP) was presented to assess the agricultural basic drought for solving the problems such as the incompatibility of drought indexes and the rough grade levels assessed by other methods. Based on the grade division standard of agricultural drought, the projection function which could reflect the variability of the agricultural basic drought system was constructed, and free search (FS) was introduced to optimize the function and seek the optimum projection vector, while the data of the vector were used to research the influential level of each drought index. In Gannan County, considered the space-time representativeness of observation data and influential degree of drought indexes on drought assessment, the percentage of precipitation anomalies and the number of days which had no available rainfall were selected to establish assessment model of agricultural basic drought based on projection pursuit. The achieved results suggested that the conclusion assessed by the model was accordant with the factual drought, and the projection pursuit model could identify the grade of agricultural drought clearly. Projection pursuit model is an effective method for assessing the agricultural basic drought.

Abstract: With the contradiction of global grain supply and demand sharpening continually in recent years, foreign scholars worry whether the sharp rise in the meat consumption in Chinese food structure is the main reason for global food tightness for the grain prices rising constantly. This paper analyzes the supporting capacity of crop straw for animal husbandry of China and food security of residents with the method of energy and energy value theory, and draws the conclusion that China's agricultural production should transform from the past model of mainly producing food into the integrated production model of maximizing agricultural biomass based on food nutrition for food consumption changes of residents. Crop straw is also the important agricultural product as crop grain, but most of it has not been fully utilized. This paper finds that China's main crop straw resource energy is huge by calculating, and according to the calculation, the wasted main crop straw resource energy in 2006 can be transformed into 5952.76 million tons meat product which is 73.93% of China's output of meat products in 2006, therefore China's comprehensive agricultural production capacity can completely meet the demand of Chinese food consumption transformation for agricultural product growth in recent years. The key question currently is how to intensively use agricultural resources and improve agricultural comprehensive utilization of biomass. The main crop straw resources in China have the characteristics of spatial distribution imbalance. The crop straw resources of different regions in China appear the north-south and east-west differences because of climate, soil and planting system. The main crop straw resources are relatively abundant in northeast while poor in southwest of China as a whole.

Abstract: In order to extend the applications of peanut protein concentrates prepared by different methods in food industry, effects of different preparation methods on the functional properties of peanut protein concentrates were studied. Peanut protein concentrates were isolated from defatted peanut protein flour by isoelectric precipitation, ethanol precipitation, isoelectric precipitation combined with ethanol precipitation, alkali solution with isoelectric precipitation and their functional properties (solubility, water holding capacity, oil binding capacity, emulsifying capacity and stability, foaming capacity and stability and gel properties) were evaluated. The results showed that the protein solubility, foaming capacity and stability of protein prepared by alkali solution with isoelectric precipitation were the best of all the peanut protein products. But the protein prepared by ethanol precipitation had better water holding capacity, oil binding capacity and gel properties, which were significantly different from other protein products. The emulsifying stabilities of protein concentrates prepared by different methods were significantly lower than that of defatted protein flour and that of protein concentrates prepared by alkali solution with isoelectric precipitation was the lowest. The results indicate that protein concentrates prepared by alkali solution with isoelectric precipitation can be suitable for food systems requiring foaming such as cake and ice cream. The protein concentrates prepared by ethanol precipitation are suitable for use in food stuffs requiring higher water holding capacity, oil binding capacity and gel properties.

Abstract: The purpose of this study was to utilize the biomass from Ulva pertusa kjellman to produce biodegradable boards for substituting the oil-based plastic materials. The experiment involved refining the Ulva pertusa kjellman in water, and then using thermostat in the same condition to defibrate fibers. In this process, fiber tip was changed to be fine cellulose. In the next process the materials were pressed for linking cellulose to be a biomass board. Finally, the biomass board was dehydrated and combined by heat conduction dryness. Technical evaluation of the resulting biodegradable board shows a rupture stress of 131 MPa, which is four times stronger compared with the polystyrene plastic material used in food container presently. Therefore, the use of biomass board as a substitute for the oil-based plastic materials as food packing container, culture pan, mulch film and so on is technically possible.

Abstract: To make clear the impact of ratios of manure to crop on dry anaerobic digestion would be of great significance to promote the practical progress of dry anaerobic digestion project. Four experiments were set at total solids (TS) of concentration of 30%: (A) pig manure alone; (B) straw alone; (C) the mass ratio of pig manure to straw of 2:1; (D) the mass ratio of pig manure to straw of 1:2. The experimental temperature was controlled at (35±1)°C. Over 62 days, operation period, the results showed that the biogas production to time curves of experiment (A), (B), (C) and (D) reached the inflection point at 48th, 40th, 26th and 25th days' respectively. The total biogas yields of experimental (C) and (D) were 15715 and 13186 mL, respectively. According to the biogas yields of experiment (A) and (B) with the materials separately, it could be calculated that the biogas production potentials of (C) and (D) were 15168 and 13838 mL, respectively. There was no significant difference between the experimental results and the calculated values. The improvement of ratio of manure to crop could promote digestion efficiency by improving the digestion speed. But no obvious effect was found on enhancing the biogas production potential. Thus, the advantages of dry anaerobic co-digestion may be of improvement to material structure and of adjustment to material nutrient, but not of enhancement of the biogas production potential.

Abstract: In order to find out the optimal catchment technology of maize planting in soil wind erosion area of Loess Plateau, soil moisture and physiological characteristics of maize were analyzed by five different planting modes which were straw mulch, planting beside filmed ridges, planting on un-filmed ridges, planting on filmed non-ridges and conventional tillage. The results showed that there were differences among soil moisture, chlorophyll content of leaf, net photosynthesis rate, transpiration rates, water use efficiency and yield characters of different treatments, and planting beside filmed ridges was the optimal planting mode. Soil moisture of cultivated layer with planting beside filmed ridges was 72.3% higher than that with conventional tillage during teaseling stage (August 9). The chlorophyll content of leaf, net photosynthesis rate, transpiration rate were 16.95%, 9.77% and 16.21% higher than those of conventional tillage, respectively. The grain yield with planting beside filmed ridges was 27.28% higher than that with conventional tillage during the whole growth period. The study shows that all the catchment modes of ridging and mulching can increase maize grain yield in soil wind erosion area of Loess Plateau, and the catchment effect of the mode of planting beside filmed ridges is the best, the yield-increasing effect is optimal. The mode of planting beside filmed ridges is the optimal planting mode which is worth to be extensively extended in the area.

Abstract: Household behaviors are the leading driving forces for the change of cultivated land quality, and their responses to cultivated land quality will affect the actual productivity. Cultivated land quality was assessed by BP neural network in Dazu County, Chongqing. The assessment results showed that paddy lands were mainly of the second-grade and third-grade, while dry lands were mainly of the first-grade and second-grade. It illustrated the high natural quality of the cultivated land, but the natural quality only reflected land natural characteristics. Therefore, influence coefficient was used to modify natural quality index based on the investigation to households. At the same time, by using the household income as the value of cultivated land, the impact of natural quality and investment structure on the value were further discussed. The results showed that trinomial equation and binomial equation were fitted to reflect the relationship between natural quality and income. In other words, household incomes were not only depended on natural attributes of cultivated land, but also affected by input and management. Because most of studied towns in Dazu County are restricted by one of investment factors, the elasticity coefficient can used to adjust the investment structure. The study shows that the cultivated land quality is not only determined by its natural properties, but also by investment, management, crop patterns and so on. Hence, measures should be taken to regulate the household behaviors in order to improve land quality.

Abstract: In order to understand the effects of rhizosphere CO2 concentration on root growth and contents of four hormones in xylem sap, areoponic cultivation experiments were conducted during anthesis and fruiting periods on root system of metted muskmelon with different CO2 concentrations. The results showed that in treatments of CO2 concentrations of 2500 and 5000 μL/L, root growth was inhibited and root activities were increased and then decreased compared with a treatment of CO2 concentration of 350 μL/L. At the same time, xylem sap volume, conductance, pH value and promoting hormone contents such as Indole acetic acid, Zeatin, Gibberellin A3, were decreased, but Abscisic acid content increased. The results show that the growth and hormone synthesis of root can be influenced when the rhizosphere CO2 concentration is greater than 2500 μL/L. It may be the important reason why areoponic cultivation advances the yield of plant compared with soil cultivation and substrate soilless cultivation.

Abstract: In order to lay the simulation foundation for variety plant design of rapeseed (Brassica napus L.), the L-system model for rapeseed (Brassica napus L.) was developed by applying parametric L-system and predefined Be´zier surface modeling methods to topological model of the flowers and inflorescence. By employing statistical analysis and normalization processing method to the data of field observation, the growth functions of the floral axis and the flower stalk were established through using Sigmoid and Weibull function, respectively. According to the algorithm of Be´zier Surface, the petals and sepal of rapeseed flower and their surface models were constructed. Finally, visual growth simulations of the rapeseed flowers and inflorescence were conducted in L-Studio 4.0 platform. The results show that the visual growth process of the rapeseed flowers and inflorescence can be realized by using this method.

Abstract: An experiment of four treatments (no-tillage + straw mulching, NTS; no-tillage + high stubble remaining, NTH; conventional tillage + straw incorporation, CTS and conventional tillage + no straw returning, CT) was designed to investigate the effects of tillage and straw returning on yearly productivity in a wheat-rice double cropping system for three consecutive years. Results show that wheat yields under NTS and NTH were low, but rice yield increased to some extent, the total yield of rice and wheat was relatively low. Providing additional wheat yield in rice seedling field needed by the latter two treatments, the total yields of rice and wheat under NTS and NTH were higher than those of CTS and CT. technically and economically, NTS could reduce the cost, increase the total income by about RMB1874.8 per hm2, about 18% raising rate, so increase the yearly economic productivity. Compared with CT, CTS achieved a higher yield and productivity. Viewing the effects of CTS on soil fertility and the decreased fertilizer usage, the efficiency was very obvious. Considering yield, quality and sustainable development, a comprehensive appraisal system was proposed to give a fair evaluation of yearly productivity of rice and wheat under different cropping systems. Four tillage and cultivation methods were evaluated according to this evaluation system. The appraisal results show that NTS won the highest score due to its highest yearly productivity. NTH, CTS took the 2nd and 3rd places. CT was the last.

Abstract: For research the effect of trapped oil pressure and teeth number on dynamic torque of external gear pump, meshing process was geometrical analyzed by dividing tooth surface into eight meshing point, three different areas and seven meshing stages. With meshing curvature radius of driving gear as a variable in a tooth period, the corresponding static and dynamic torque formula were derived. The special analysis and comparison were achieved with an instance. All results indicated that the higher trapped oil pressure, the more fluctuation of torque and higher value of max amplitude, but the min amplitude of torque was generally unchanged; the quality of meshing torque with the same teeth number of the gears was better than dissimilar teeth number. Static torque formula had a bigger calculation error. A lot of important conclusions were educed, which trapped oil pressure had a great negative influence on torque, and dissimilar teeth number of meshing gears had different influence on various performance of external gear pump, therefore trapped oil pressure should be eliminated as far as possible and the predominance of dissimilar teeth number on uniform teeth number wasn't absolutely positive.

Abstract: Rosin glysin ester was used as the coating material to produce the coated fertilizers. The slow release properties of caoted urea were studied by the method of potted plant soil. The results showed that the early rate of nutrient released from coated-urea was 12.9%. According to the logistic growth model, when the coating coverage was 5%, the biggest nutrient release rate from coated urea was 96%, and the period of nutrient release was 146 days. When the coating coverage was 8.1%, the biggest nutrient release rate from coated urea was 97%, and the period of nutrient release was 194 days. The period of nutrient release varies with the coating coverage. Rosin glysin ester is a new choice for coating materials.

Abstract: Horseshoe section tunnel is a common type in the free-flow tunnel. There is no analytical expression to solve the critical depth of horseshoe section tunnel under free flow. The traditional solving methods, such as trial method and chart method, are very complicated with low precision. In this study, by mathematical transformation of critical flow equation of horseshoe section tunnel, the relationship between the dimensionless parameters and relative critical depth was analyzed and simulated. Using the gradual optimization and fitting principle, a direct formula for calculating the critical depths of standard I-type and II-type horseshoe section tunnel was established. Results of the example calculation and error analysis show that the maximum relative error of critical depth is 0.8%, in agreement with the application scope of engineering. The characteristics of this formula is exact and simple, which supplies a reference to manual compilation of engineering design and hydraulic design.

Abstract: Biomass pyrolysis has attracted significant interest in recent years. However, traditional pyrolysis technologies such as fluidized bed type of pyrolysis technique require biomass to be ground into fine particles which adds a lot of energy input and cost. In addition, bio-oil and syngas products produced are often contaminated by the incomplete reacted biomass materials. Microwave pyrolysis helps solve those problems, however, just like other pyrolysis technologies, the bio-oil products from current pyrolysis technologies including microwave are still very complex in composition, acidic, and not stable, which prevent the commercialization of the pyrolysis technology, even though the cost of bio-oil production from pyrolysis is much less than that of biological approach. The study intends to help solve this exact problem. Corn stover was used as feedstock, and the effects of catalysts on the product selectivity of microwave assisted pyrolysis were investigated. Many kinds of acids, alkali, metal oxides, and salts were tested as catalysts for pyrolysis. The bio-oil compositions were analyzed with GC-MS. It was found that when corn stover pellets were pre-mixed with some kinds of acids, and/or chloride salts prior to microwave assisted pyrolysis, the components of the liquid bio-oil products were very simple.

Abstract: It could wash most of metal elements in corn stalk such as K, Ca, Mg and P by 0.01% dilute sulfuric acid. Equivalent metal chlorides were added to the washed corn stalk while pretreated with 0.1% dilute sulfuric acid, and hemicellulose degradation rate could reach 37%, enzymatic digestibility rate of the pretreated corn stalk could reach as much as 23%, while treated with 0.1% dilute sulfuric acid, the results were 17% and 12% respectively. Metal chloride produced a significant drop in pH value, but at the same pH value, when treated with pure sulfuric acid, hemicellulose degradation rate was 19% less than 37% when treated with 0.1% diluted sulfuric acid added with metal chloride. In addition, FeCl3 significantly increased the hemicellulose degradation rate. Metal chlorides, especially FeCl3 can promote hemicellulose decomposition, and the drop of pH value is not the vital cause.

Abstract: A new in-situ monitoring system for chlorophyll fluorescence is proposed, using light-emitting diode (LED) excitation by means of the Pulse-amplitude-modulation (PAM) fluorescence detection technology. The system takes programmable power supply as drive power of LED array illumination with high sensitivity and signal-to-noise ratio. The system uses MINIPAM to measure fluorescence parameters such as Fs and Fm'. With the detection of temperature and PAR, and the measurement of other environmental factors, comprehensive analysis of the relationship between environmental factors and the chlorophyll fluorescence parameters such as the impact was conducted. The upper PC can control the power supply and process the data received from MINIPAM by software which programmed in Delphi7. The system takes the monitoring software which was programmed by Delphi7.0 on plants under the fluorescent light to conduct real-time online monitoring of parameters. The results show that, comparing with traditional method, the system has a lot of advantages such as high accuracy and good reliability and convenience. It will be a practical measurement and control system for photosynthesis ability and have a wide application foreground.

Abstract: Soil water resource is very important to the growth and development of plants on the Loess Plateau. Soil and water conservation measures have impacted on the static distribution and dynamic process of the soil water resource. Based on data collected by random survey of soil moisture and compensation degree of soil water storage deficit, the soil moisture dynamics and the compensation characteristics of soil water deficit under different measures of soil and water conservation in the loess hilly and gully region were analyzed. The results show that, no matter before or after rainy season, soil water storage under different measures of soil and water conservation was deficient and then increased in July. In August, soil water storage deficit in surface layer increased. After rainy season, soil water storage deficit was restored by precipitation in October. The compensation effect of precipitation on soil water storage of crop land and terraced land was positive. But this effect was negative at the depth of

Abstract: In order to determine the applicability of visible-near infrared spectroscopy models for determining Soluble Solid Content (SSC) and Total Acid (TA) in 'Nanguo' pears during storage period, the variance analysis of soluble solid content, total acid contents and Visible-Near Infrared (VIS-NIR) Spectra of 'Nanguo' pears during different storage periods were conducted by using Duncan's new multiple range method. The models with samples stored for six days after harvest at room temperature were established based on partial least squares method and then the prediction performance during different storage periods of 'Nanguo' pears were assessed. Results showed that changes of spectra agreed well with those of soluble solid and total acid contents during the storage period of 18 days after harvest at room temperature, whereas the same results were not found in the period of cold storage for 120 days after harvest. The calibrated correlation coefficients of models for determining SSC and TA contents in 'Nanguo' pears were higher than 0.83. The predicted correlation coefficients of models both for pears stored at room temperature for 12 days after harvest and for pears in cold storage for 120 days were higher than 0.8. Thus the model was applicable during different storage periods. The results support the application of non-destructive classification for 'Nanguo' pears by using visible-near infrared spectroscopy technology.

Abstract: Channel siltation is the key point which affects the working for the high-silt conveyance channel in irrigation area. This paper takes the siltation calculation of the secondary channel of An-Jihai reservoir in Xinjiang Ba-Yin river as an example. According to the theoretical calculation results of sediment threshold velocity and water flow velocity, sediment discharge of bed load and silt carrying capacity, the cause of silt deposition of high-silt laden conveyance channel was analyzed from different aspects. The results of theoretical calculation indicate that water flow velocity should not only be considered that it is greater than competent velocity in designing channel, its transport capacity should also be checked according to the minimal slope of channel when the slope of channel changes along the length to prevent channel from silting. To verify the accuracy of the above calculation, the prototype observation experiment was carried out. The results show that theoretical calculation result accords with prototype observation, and the theory calculation process of channel is rational and reliable, which can provide some important references for engineering design and management units.

Abstract: The qualities of sweet potato starch noodles (SPSN) were greatly influenced by the physicochemical, thermal properties and molecular structure of sweet potato starches (SPS). The physicochemical, thermal properties, molecular structure of SPS and the qualities of SPSN were determined. Mung bean starch and its noodles were used as the control. The correlation between the physicochemical, thermal properties, molecular structure of SPS and the qualities of SPSN were analyzed. The results indicated that qualities of SPSN were crucially affected by its physicochemical properties. These influential parameters were in turn according to the r value: swelling power > solubility > amylose content > protein content > granule size. Furthermore, the effect of retrogradation on quality of starch noodles was greater than that of gelatinization. There was a significant correlation between the quality of starch noodles and the RVA parameters, which was considered as an important way of predicting the qualities of starch noodles. The factors affecting the qualities of SPSN in a descending order were amylose content, short chains amount of amylopectin, long chains amount of amylopectin, branching degree of amylose, short chains length of amylopectin, chains length of amylase, long chains length of amylopectin.

Abstract: Characteristics of drought resistance and water logging tolerance of rice were used for a new water-saving irrigation mode, water-catching and controlled irrigation (WCCI). The mode maintained higher water depth after rainfall than continuous flooding irrigation (CFI) and kept low irrigation limit as controllable irrigation (CI) so as to improve rainwater use efficiency. Water consumption, irrigation quota, drainage quota, rainwater use efficiency, agronomy indexes and yield of rice under WCCI were investigated and the differences among CFI, CI and WCCT were also analyzed by plot experiments with hybrid rice cultivar "K you 818" as material. The results showed that water consumption under WCCI decreased 15.0% compared with CFI while increased 20.4% compared with CI. The irrigation quota after transplant under WCCI decreased 20.8%, 46.9% and drainage quota decreased 83.9%, 87.2%, respectively, compared with CFI and CI while rainwater use efficiency increased 36.84%, 48.02%, respectively. Plant height and productive panicle number under WCCI increased while leaf area index (LAI) decreased compared with CFI. Grain yield under WCCI was higher than that under CFI and CI. The results indicate that WCCI will be a water-saving, high-efficiency irrigation model of rice, and the model is suitable for rainy regions in South China.

Abstract: In order to search for the optimum drying method of porcine serum immunoglobulin G(IgG), the feasibility of spray drying and practical effects of thermal protectants were investigated in this paper. The effects of drying methods on porcine serum IgG activity and purity were compared. The results showed that the activity loss of porcine serum IgG was reduced effectively by combining with protectants which was made up of 0.5% (m/V) glycine, 5% (m/V) maltase and 20%(m/V) defatted milk powder during spray drying. The activity loss of porcine serum IgG was reduced using mycoses as the protectants. The content and activity preservation rate of IgG depend on the drying methods and drying protectants.

Abstract: An experimental device for drying grapes was designed according the principle of air-impingement jet technology. For this device, the hot air temperature and velocity were automatically controlled, the relative humidity of heat media could be monitored, and moreover, all of the data could be collected and saved. Based on this device, the drying technique and drying quality of Monukka grapes were studied. Experimental results showed that the drying curves of Monukka included three stages of pre-heating, constant rate drying and retarded drying. As the increasing of impingement temperature and hot air velocity, the drying rate of constant rate drying stage was improved, the drying time of this stage was shortened, but those factors were insignificant in retarded drying stage. There were no significant differences in the quality indexes of raisins at the range of experimental drying temperatures and velocities. The kinetics of the degradation of ascorbic acid was also studied under various drying temperatures. The pilot equipment of air-impingement jet dryer was developed and put into operation. The optimum technological parameters were air temperature of

Abstract: A nutrient balance decision support system (DSS) in agro-ecosystem was constructed. Based on DSS, the status quo and historical trend of nitrogen balance was analyzed in both county level and province level. The results showed that: 1) nitrogen surplus displayed an upward trend from 1978 to 2005, which increased from 10.55 million tones in 1978 to 28.67 million tones in 2005. Increase rate reached 64.7 × 104 t/a; 2) there were significant inter-provincial differences. In general, the nitrogen surplus in main cereals producing provinces such as Shandong, Henan and Sichuan kept a long-term high level. Contrarily, the provinces located in northwest China or southwest China such as Xinjiang and Tibet had a low nitrogen surplus for a long time. The long-term and increasing nitrogen surplus of agro-ecosystem in major cereal product areas of China showed that nitrogen input, mainly from chemical fertilizer, was far more than nitrogen demand for crops. The surplus nitrogen accumulated in field will discharge into water body and atmosphere by many different processes, which will cause the waste of nitrogen resources and potential environmental risk.

Abstract: Water distribution characteristics are important technical parameters to measure the quality of water saving irrigation. In order to find out the test method and judging standard of water distribution uniformity coefficient of micro-sprinkling hose, a detection method of water distribution characteristics of micro-sprinkling hose was studied based on the detection method of rotating sprinkler water distribution characteristics. The water distribution uniformity coefficients of several typical micro-sprinkling hoses were measured by the detection method. The results showed that the water distribution uniformity coefficients were lower than that of rotating sprinkler. The largest water distribution uniformity coefficient of micro-sprinkling hoses was 78.34%, and the lowest one was only 24.55%. The main factors which affected the water distribution characteristics of micro-sprinkling hose were analyzed. According to the water distribution characteristics, micro-sprinkling hoses should be classified into three types, which can application in different situations.

Abstract: For searching the transport law of water and fertilizer under given conditions, based on lab experiment, the influences of soil textures on transport characteristics of water and distribution of NO3--N under single film hole infiltration of fertilizer solution were researched. The cumulative infiltration volume of soils with different textures followed the Kostiakov infiltration model. The relationships between transport distances of vertical and horizontal wetting fronts and infiltration time followed the power function equation. Soil texture had a significant influence on distribution and redistribution of soil water content. Distribution of the NO3--N contents of soils with different soil textures were relatively even and there were less difference on the NO3--N contents of soils at the

Abstract: Separation performance and purification of xylo-oligosaccharides (XOs) solution derived from wheat straw by a nanofiltration (NF) membrane with a molecular weight cut-offs (MWCO) of 250 were investigated. The profiles of rejections of the arabinose, xylose and XOs with degree of polymerization (DP) from two to four at different membrane fluxes were obtained based on the detection of their concentrations in filtrate and retention. According to irreversible thermodynamics model, reflection coefficient, solute permeability, solution hydraulic permeability of arabinose, xylose and XOs with degree of polymerization (DP) from two to four were estimated. Furthermore, the membrane structure parameters were estimated by Steric-hindrance pore model. When feed concentration (total saccharide/syrup), membrane system temperature and trans-membrane pressure were 8.4%, (30.1±2.1)°C and (1.58±0.02)×106 Pa, respectively, the flux was (29.4±1.8) L/(m2·h) without declination during diafltration, and the ultimate XOs content reached 92.54% (XOs/total saccharide) from 83.33%. The yield of total saccharide and the loss of xylobinose were 88.39% and 12.45%, respectively, after the addition of three times volumes of water. This investigation provides a basis of parameters for purification by diafiltration, concentration and optimization of those processes. Diafiltration with NF can efficiently remove monosaccharides with less loss of XOs.

Abstract: The complete fluidic sprinkler was originally invented in China. Its design method has not yet fully grasped. Design method of the complete fluidic sprinkler was put forward firstly. An orthogonal array with four factors and three levels was selected to carry out the experiments. The optimum values of structure parameters were confirmed after the experiments. The influencing factors in decreasing order of importance for stepped frequency were contractive angle, water fetching angle, offset length and working area. The influencing factors for stepped angle were offset length, contractive angle, water fetching angle and working area in decreasing order of importance. The important structure parameters were confirmed as follow, the size of base circle was determined by the type of the sprinkler. Design method for water inlet and air inlet were the same. 14 and 30 degrees were defined for contractive angle and water fetching angle respectively. The equation of offset length and base circle relationship as well as the equation of working area and base circle were established using the method of quadratic regression analysis.

Abstract: Based on the method for calculating flow deviation of drip irrigation system taking hydraulic deviation and terrain slope into account, according to the disadvantage combination principle and the probability theory, the effect of manufacturing deviation on flow deviation rate was analyzed to imitate flow deviation of drip irrigation system accurately for designing drip irrigation system economically and credibly. The relationships between flow deviation rate and manufacturing deviation rate, hydraulic deviation rate and terrain deviation rate in drip irrigation system were established on uniform slopes by hydraulic calculation and mathematic consequence. Taking the three deviation rates into account, a formula for computing the flow deviation rate was deduced. The formula can simulate flow deviation rate at different guarantee rates for a drip irrigation system, which is simple and practical. It can be used in the design of drip irrigation project.

Abstract: In order to discuss the effects of different tillage measures on soil respiration emission and the relationship between soil respiration emission and soil temperature, soil respiration emission and soil moisture, experiments were conducted at long-term sited station to investigate the CO2 emission fluxes and their seasonal variation of winter wheat and summer maize with different tillage measures (conventional tillage, rotary tillage and no-tillage). The CO2 emission fluxes, soil temperature and soil water were analyzed by regression statistical analysis. The results showed that the CO2 emission fluxes had obvious fluctuating with the different seasons. The order of CO2 emission fluxes were CT (conventional tillage) >RT (rotary tillage) >NT (no-tillage) during the growing periods of winter wheat and summer maize, and the differences between the tillage measures were significant or very significant. Soil temperature and moisture were significantly affected by tillage practices, so soil temperatures in all layers of NT were the lowest, and the data of moisture were higher than the other two treatments. The CO2 emission fluxes and the soil temperature showed significant correlation, especially at the depth of

Abstract: In order to improve the degradation reaction activity of microorganisms of maize starch, maize starch was mechanically activated by a stirring-type ball mill, using distillers yeast as the biodegradation reagent, maize starch with 60 minutes of activation time and native starch was degraded. The effects were investigated that gelatinization temperature, pH value, starch concentration, degradation time, degradation temperature and microorganisms fluids dosage influenced on degradation reaction of microorganisms from maize starch, using dextrose equivalent (DE) of the hydrolysis product of starch acetate as evaluating parameter. The morphology of the degrade process of maize starch with mechanical activated was investigated by scanning electron microscope (SEM). The results indicated that the DE increased with mechanical activation, and the maize starch with mechanical activated can be directly biodegradation without a gelatinization. The DE was 36.76% after biodegradation for 60 min, comparing with non-activated maize starch, and the DE increased by 27.80%. Mechanical activation greatly increased degradation reaction activity of microorganisms of maize starch. It indicated that the crystal structure and compact granule surface of maize starch were destroyed by mechanical activation.

In this study, path planning is translated into three dimensional Travel Salesman Problem. According to the apple position obtained through image processing, an improved ant colony algorithm was studied in the optimization of apple-picking path, which can overcome premature convergence and local convergence of the search. Three-dimensional model building and driving methods were studied. Experimental results show that when there are 250 apples, the improved ant colony algorithm can reduce alternate times to 25.3% of basic algorithm, while the total distance is 94.3%, therefore, the improved ant colony algorithm cannot only reduce algorithm times, but also can obtain better values. This study is of great importance to the optimization of apple-picking path.
