Abstract: In order to promote maize drought resistance and disaster reduction,field experiments and large area comparative design were used in this study,six straw returning treatments were set up,included ploughing and burying,crushing and mixing,returning to cover,deep loosening mulching in autumn,deep loosening mulching after seedling,and no-tillage without straw,and the effects of different straw returning methods on maize yield and benefit as well as drought resistance were analyzed.The results showed that the soil water content of straw returning to cover,crushing and mixing and deep loosening mulching after seedling was significantly higher than that of the control.The water use efficiency of straw ploughing and burying,deep loosening mulching in autumn and deep loosening mulching after seedling was significantly higher than that of the control.The yield of maize under straw ploughing and burying and deep loosening mulching in autumn was significantly higher than that of the control.The net income of straw ploughing and burying to field was the highest,reaching8 471.66 yuan·hm^-2.
