| 摘 要： | 研究谷子、大豆植被过滤带对黑土缓坡耕地泥沙及氮、磷养分的拦蓄特征,为农业面源污染的防控提供技术支撑。试验结果表明:2种植被过滤带对泥沙及氮、磷养分的拦蓄量均随过滤带宽度的增加而增大;过滤带对氮的拦蓄效应大于对磷的拦蓄效应;过滤带的泥沙拦蓄量与过滤带宽度之间的相关性是谷子大于大豆,即谷子对过滤带宽度的要求高于大豆。

| Abstract: | Interception characteristics of millet and soybean vegetation filter strips for sediment and N and P nutrients on black soil sloping farmland were studied and technical support for agricultural non-point source pollution prevention and control was provided.The study shows that interception amount of sediment and N and P nutrients increased with the increase of width of two kinds of filter strip;intercepting effect of N was greater than that of P;Response of millet to filter strip width was higher than that of soybean. |

| Keywords: | sloping farmland vegetation filter strip characteristic of interception N P |
