Abstract:: Planting orchard is the main land utilization pattern in red soil of southern hilly slope. However, the traditional and extensive cultivation resulted in serious soil erosion. In order to choose the synthetic developing pattern and prevent soil erosion, in this paper, through the five years field observation, the difference among eight intercropping patterns in conserving soil and water were studied. The results showed that, different intercropping pattern, different grass and tillage in the pattern have different effect of controlling soil erosion and conserving water; Compared to the single orchard, Inter-cropping Bahia grass over the orchards have the best benefits in preventing soil erosion. The function of intercropping grasses was obviously better than that of intercropping crop in soil and water conservation. While coverage of grasses reached more than 80%, runoff and sediment could be decreased by 92%. Moreover, the effects on runoff and sediment reduction of horizontal intercropping were higher than 20% above the down slope farming.
