麦棉套种膜上灌溉节水增产机理研究

试验研究采用麦棉套膜上灌——土壤水分——作物——农田小气候理论体系，测定膜上灌灌水条件下的水流特征和土壤水分循环特点，麦棉共生期作物生育特性和农田小气候的相互关系。揭示出麦棉套膜上灌和棉花膜上灌分别节水２９％和４７％，小麦增产３．８％及棉花增产１１．８％的节水增产机理

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.
