Abstract:: Using the field plot test, we had investigated the soil erosion on sloping lands in which the green manure was grown, observed the impact on soil coverage, soil moisture, soil water content and the crop yield. We hope to seek for the rule to control the soil erosion with green manure. The results showed that planting and incorporation of green manure could reduce the overland runoff and the amount of soil erosion and improve the dry slope land coverage. Compared with control, common vetch-corn and bean was the best planting pattern, which could reduce the surface runoff by 62.60% and the soil erosion by 78.4%, improve the dry slope land coverage by 52.08%~66.67%. Compared with control, the vetch-corn pattern could improve the corn grain by 35.25% and straw yield by 34.08%. Meanwhile, the common vetch-corn and bean pattern could improve the corn by 25.8% and straw yield by 39.7%. In addition, the bean and straw were 814.5 kg/hm² and 1 006.5 kg/hm², respectively. In conclusion, planting and incorporation of green manure can reduce the soil erosion and increase soil water storage ability when it is abundant in rainfall. On the country, it could increase the yield, and enhance the soil to supply more water when there is less rainfall.
