Initial Discuss on the Application of the legumnious forage - chamaecrista rotundifolia in the Chinese Olive Orchard on Red Soil Slope Land at Both Sides of Lower Reaches of Minjiang River

After years observation at fixed points to the experiments of interplanting the chamaecrista rotundifolia,legumnious forage in the Chinese olive orchard on the red soil slope land at both sides of lower reaches of Minjiang River,it is concluded that the interplanting of chamaecrista rotundifolia will rapidly cover the young orchard,improve the soil fertility so as to reduce the soil erosion at the initial stage of orchard development.The interplanting will also increase the moisture content of soil in part area,to improve the growing environment of the fruit trees and to improve the yield of the orchard so as to increase the orchard benefit.
