香根草技术在道路路基防护与绿化上的作用

Function of Vetiver Grass Technology on Road Embankment Protection and Greenization

香根草具有耐涝、耐旱、耐瘠、耐火、生长快等生物学特性。同时又具有优良的工程参数如抗张强度、剪切强度、穿透性等 ,其庞大深扎的根系可有效地固定坡地土壤 ,防止浅层土体的位移。它易种植、好管理、成本低、所形成的绿篱可有效地防治水土流失 ,保护公路、铁路边坡 ,以及稳固堤岸、水坝。

Vetiver grass is tolerant to water logging ,draught,and fire.It is a fast growing grass and can be planted on barren soil.Meanwhile,it has excellent engineering parameters,such as shear strength,tensile strength,and penetration.Its roots can stabilize soil effectively and protect soil from removing.
