| Abstract: |
| With field simulation experiment and field experiment , the paper studies the effect of conservation tillage on rainfall infiltration, the increasing of soil moisture in different soil depth, and the yield and water use efficiency of winter wheat. The results show that the conservation tillage can remarkably delay runoff and improved the infiltration rate compared to conventional tillage. The final infiltration rate could be 1.226.67 times compared to that of conventional tillage. No tillage and subsoiling tillage could increase rainfall storage by 6.5% and 7.4%, yield of winter wheat by 17.78% and 16.1%, and water use efficiency by 1.52 kg/ (mm·hm2) and 1.00 kg/ (mm·hm2). |
