不同植物篱对丹江口库区坡耕地水土流失及养分保蓄效应研究

The Research of Different Alley Cropping on the Soil Erosion and the Effects of Nutrient Paul on Slope Farmland in DanjianKou Reservior

通过在丹江口库区坡耕地上不同植物篱的种植试验，观测分析了不同植物篱对坡耕地水土流失及养分保蓄的效应。结果表明：紫穗槐、金银花、黄花菜及龙须草4种不同植物篱均能有效减少坡耕地上的泥沙流失量，并可有效防止N、P、K的流失，4种植物篱以黄花菜的效果最好。

Via the different hedgerow planting experiment on slope farmland in DanjianKou reservior, This paper observation and analysis of different hedgerow soil erosion and paul nutrients build. The re- suits showed that： 4 different hedgerow：Amorpha, honeysuckle, Hemerocallis, and Alpine Rush can ef- fectively reduce the slope of the sediment and can effectively prevent the loss of N, P, K, the best of four kinds of plants fence is Hemerocallis.
