Abstract: The green manure planting benefit, feasibility and the reasons of planting area reducing were investigated and surveyed,and the countermeasures and suggestions were put forward. The results show that planting benefit of green manure is remarkable,first,which can improve soil organic matter content and physical and chemical properties,and increase the utilization rate of nutrients and crop nutrient supply;Second,which can increase crop yield,reduce the fertilizer input,enhance the output value of agricultural products,and eliminate the continuous cropping obstacle;Third, which can effectively broade the industry,promote planting and breeding,dock rural tourism and development new industries. Hubei province has a successful green manure planting history,development area is larger,and financial support for green manure planting experiment and demonstration obtained obvious effect. Because direct economic benefit is not obvious,the contradiction in water supply is highlight,basic-level agro-technique extension is difficult,and the problem such as supporting technology is not mature,green manure planting area of Hubei province have not been able to improve. To expand cultivated area of green manure and implement the central concept of green development,demonstration and propaganda should be strengthened, the way of financial support should be actively widen,the multi-sectoral cooperation mechanisms should be build,the entire social service tone should be strengthen,and measures to green manure production pattern should be build by local conditions.

Key words: green manure, planting benefit, planting area
