Abstract:Abstract: Interplanting can not only improves the cropping index, light energy utilization and economic benefit of forest land, but also stenters branch leaves or bind can natural cover the barrens, reduces the soil temperature, mitigates the storm’s direct erosion on the soil and reduces loss of the water, soil, and fertilizer;After harvest, it’s remainder can return to the forest land which have a good effect on the soil nutrient content’s increasing and soil structure’s improving.The authors summarizes the effect of interplanting on the soil fertility factors of water, fertilizer, air and heat etc., the tree growth,the fruit quality and the economic benefit, and it provide the reference and basis for the exploration of the effect of interplanting on the fruit forest.
