摘　　要：测定了不同麦棉套作方式下的小麦棵间蒸发量,分析了麦棉套作小麦棵间蒸发日变化规律,研究了不同生育阶段的棵间蒸发量与耗水量,并建立了麦棉套作小麦棵间蒸发与单作小麦棵间蒸发比值与叶面积指数和株高的复合函数关系.Soil evaporation under different planting patterns was measured by using Micro-lysimeters in this paper. The daily variation characteristics of soil evaporation were analgzed, the soil evaporation on different places was compared, and the soil evaporation and water consumption at each stage were studied. The function relations between the ratio of soil evaporation of intereropping wheat to soil evaporation of single cropping and leaf area index or plant height were established.
