Planting the green manure could provide nutrient, fertilize the soil fertility, improve soil structure, provide forage grass, safeguard food security, improve ecological environment, save energy and decrease consumption, and has an important development significance in China tradition agriculture. Green manure germplasm resources are rich in China, which mainly include Leguminosae, Gramineae, Brassicaceae, Compositae and etc. The green manure application models include intercropping model, rotation model, used model both as fertilizer and feed, orchard green manure planting model. Regional distribution of different models is different, because weather pattern and crops planter pattern are different. This paper summarized the research work on green manure main variety resources, main green manure application patterns and green manure effects in China and pointed out green manure future development directions.
