中文摘要:污水水质及灌溉制度是影响污水灌溉安全性的主要因素。盆栽试验设置了两种水质(清水和污水)和4个灌水下限(60%fc,70%fc,80%fc,90%fc),共8个处理,研究了污灌条件下不同灌水下限对小白菜生长及品质的影响。试验结果表明:生活污水灌溉会造成小白菜轻度减产,植株的硝酸盐含量和叶片叶绿素含量增加,植株重金属累积增加;灌水下限对小白菜生长状况和品质均有较大影响,污水灌溉条件下各项指标随灌水下限变化的变化规律不同于清水灌溉条件,表明污水灌溉的灌水下限不能直接移用清水灌溉的控制指标。综合分析表明污水灌溉80%fc灌水下限条件下小白菜有较高的产量、水分利用效率和叶绿素含量,较低的硝酸盐含量和重金属富集,因此选择土壤相对含水率80%fc以及与此相对应的叶片细胞液浓度9.3%作为污水灌溉的灌水下限指标。

Abstract:Water quality and irrigation schedule restrict the development of wastewater irrigation. Two water quality treatments(clean water and wastewater), and four lower limits of soil moisture for irrigation(60%fc, 70%fc, 80%fc, 90%fc), eight treatments in total were set in pots experiment. Influences of different lower limits of soil moisture on the growth and quality of Chinese cabbage were analyzed with wastewater irrigation. Results show that domestic wastewater irrigation reduce the yield gently, increase nitrate and chlorophyll content of vegetable leaves, and enhance heavy metal accumulation. Lower limits of irrigation impacted growth and quality dramatically, and the varieties of crop and soil as irrigation limitation changes under wastewater irrigation are different with that under clean water irrigation, which indicates that proper lower limit of irrigation under wastewater irrigation can not refer to the index of clean water irrigation. Integrated analysis indicate that Chinese cabbage has higher yield, water use efficiency, chlorophyll, and lower nitrate, lower heavy metal accumulation under irrigation with 80% field capacity of soil moisture as lower limit. Therefore, 80%fc soil moisture and 9.3% of leaf cell sap concentration relatively are determined to be the proper lower limit of soil moisture for wastewater irrigation on Chinese cabbage.
