摘要： 旱作垅种（小麦）沟盖（玉米）地膜带田优于目前推广的沟种（小麦）垅盖（玉米）带田种植形式。在作物共生期相互调水作用更趋合理,平衡了小麦、玉米不同生育阶段对水分的供需矛盾,作物的生态条件更加适宜,群体结构更加协调,提高了作物的生产量,前者比后者增产９０％～１２５％。

关键词: 旱作带田, 垅种沟盖, 集水调水, 增产效应

Abstract: The growth pattern of wheat planted on ridges and corn in furrows with plastic canopy on striped rainfed farmland is superior to the presently extended growth pattern of wheat planted in furrows and corn on ridges,both mulched.In the symbiotic stage,crops have the equitable effect upon mutual water regulation,coordination and balance of water requirements by wheat and corn in the different deve lopment stages.Therefore,the crop living condition would be more suitable,and the structure of colony more coordinative.The former can raise crop yield by 9 0%～12 5% in contrast to the latter.

Key words: striped rainfed farmland, wheat planted in furrow and corn on ridge mulched, rainwater collection and regulation, yield increase efficiency
