香根草[Vitveria Zizanioides (L.)Nash]属禾本科多年丛生植物,具有适应性广易繁殖、生长快、根系发达、耐早耐瘠薄等特点。 香根草植物篱是防治坡耕地水土流失的一项新技术,即在坡耕地上把香根草种植成宽约0.3～0.5米连续的等高草带,相邻篱间为农田。植物篱如同透水的挡坝,当坡面径流通过该篱时流速降低,侵蚀能力减弱,径流携带的 Vetiver [Vitveria Zizanioides (L.) Nash] is a perennial gramineous plant species, with wide adaptability, rapid growth, root system development, resistance to early barren and so on. Vetiver grass hedgerows are a new technology to prevent and control soil erosion on sloping fields. Vetiver grass is planted on a sloping farmland into a continuous contour grass strip with a width of 0.3-0.5 meters. The adjacent hedgerows are farmland. Hedge hedgerows are permeable dams that reduce flow velocity and reduce erosion as runoff passes through the fence,
