摘　　要：1 997～ 1 999年试验结果表明 :丘陵红壤坡耕地实施香根草篱开发 ,可使地表径流量、土壤冲刷量和养分流失总量分别减少 60 .1 %～ 72 .4%、5 6.2 %～ 77.9%、69.2 %～ 90 .4% ,可使土壤临界侵蚀量提高 2 .7mm ,花生产量年均提高 1 0 .3%。而且 ,2～ 3年后 。The experiment in control effect of the hedge of vetiver grass on red soil sloping land erosion was conducted during 1997～1999, the results showed that the hedge of vetiver grass could decrease runoff, soil loss and total nutrient loss by 60.1%～72.4%, 56.2%～77.9% and 69.2%～90.4% respectively, and could enhance the critical value of rainfall of causing soil loss by 2.7mm and yearly average peanut yield by 10.3%. In 2～3 years after planting vetiver grass, its effect of conserving soil and water would be close to that of terrace land.
