Effects of intercropping green manure on yeild and economic benefits of orchard

The research analyzed the effects of different green manure crops on orchard soil temperature， humidity environment，tree growth potential，fruit quality and economic benefits，to selected the green manure crops which were fit for planting in Ili valley region，and improve the scientific management mode of orchard ecological environment. Five different treatments，that orchard was intercropped with sainfoin，alfalfa，soy，wheat，Qinggeng （CK）were designed. The water retention，heat preservation ability，yield and fruit quality of orchard intercropped with green manure were determined and analyzed with variance components method. It was found that intercropped with different green manure not only improved the soil temperature and humidity environment，but also could enhance the fruit tree potential effectively，ensure the fruit yield and quality，then improve the economic benefits of orchard. The green manure production development suitable for Ili river valley was in turn: alfalfa > beans > sainfoin > wheat > Qinggeng（ CK）.
