Effects of cultivation management on soil erosion were studied with runoff-plots.The results showed that Treatment B (contour planting in furrows with polythene mulch,straw mulch) could effectively reduce surface runoff and soil erosion,preserve the tillage layer,and promote sustainable development of the agriculture.Total runoff of Treatment B,A,and C reduced surface runoff by 79.13%,69.76%,and 50.61%,and total erosion by 86.81%、72.75%、50.90%,compared with Treatment D.
