| Abstract: |
| In view of the characteristic of spring drought occurring in nine years in a decade in Chaoyang semi-arid region, five different treatments on corn stubble after autumn, including stubble remaining without covering, stubble covered with straw, tillage without covering, tillage plus straw covering and tillage plus film covering, are designed to study the effect of each treatment on surface soil moisture before spring sowing.The results indicate that before spring sowing, the amount of soil moisture of surface layer in different treatments is in the order of tillage plus film covering > tillage plus straw covering > stubble covered with straw> tillage without covering> stubble remaining without covering, and the soil water content of tillage plus film covering is 17.03%, being 4.51, 2.57, 1.27 and 0.66 percentage points higher than stubble remaining, tillage without covering, stubble plus straw covering and tillage plus straw covering respectively. |
