摘要
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．
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, increasing in yield of 3.8 % and 11.8% respectively for wheat and cotton.
