Mechanism of Water Saving and High Yielding Under Furrow Irrigation on the Plastic Film in Wheat Cotton Intercropping Field

Using the irrigation soil moisture plant agricultural microclimate theoretical system to study the flow phenomena under the irrigation of water delivered on the plastic film covered wheat-cotton intercropping field, the characteristic of soil moisture circulation and the relationship between growth habit under wheat-cotton symbiotic conditions and agricultural microclimate. The results show there are water saving about 29 % and 47 % respectively for symbiotic conditions and cotton growth only, intercropping in yield of 3.8% and 11.8% respectively for wheat and cotton.
