Abstract: In order to determine the optimum green manure in different ecological regions, the effects of turnover of different green manure on corn yield and soil properties were studied by plot experiment. The results showed that the biological character of Vicia villosa Roth var. was the best, it was better to improve corn diameter, length, biological yield and nutrient, especially in phosphorus deficiency regions, but it should be buried in early time in order to improve the effective number of corn plant; milk vetch was better to increase corn kernel yield, straw yield; wheat had positive significance in the improvement of harden clay, while the seeding time of wheat and ryegrass should be early, ryegrass was good green manure in phosphorus deficiency regions; common vetch was good green manure to increase the soil microbes and enzyme activity, and had better biological character; Raphanus sativus L. was good green manure to improve acidic soil and improve biology yield and nutrient, especially in the phosphorus deficiency regions. From the aspect of aggregative indices, common vetch was the most suitable green manure in Xiangxi Zhou.
