Preventing soil losses and improving productivity of slope cropland are the main targets of agricultural technique of plant hedge-rows, which is an effective way to utilize the slopeland and plays an important role in the sustainable development of eco-environment, resource and economy in the hill area. It was shown in the two years experiments that such technique has the ability to effectively control erosion, to improve soil fertility and to increase the soil effective-water content and to promote the land productivity. The technique can be widely extended in the hill area.
