【摘要】 采用香根草生物技术措施进行公路边坡治理,投入成本仅为纯工程措施的1/5～1/10,绿化覆盖率达90%以上,经济和生态效益明显;香根草配方基质育苗种植和合理施肥技术的运用,使种植的香根草成活率提高近30%;香根草在锰矿渣边坡种植成活率71%,坡面覆盖达50%,证明香根草能够在有毒的废矿上生长。更多还原

【Abstract】 Stabilizing side slope of highway by using Vetiveria zizanionides technique had obvious economic and ecological benefits that its afforestation cover rate reached 90%, but the cost correspond from one fifth to one tenth of engineering measure. The survival rate increased nearly 30% by applying artificial media for breeding seedling and rational fertilization. Even though planting Vetiveria zizanionides on the manganese slag slope beside highway, its survival rate yet reached 71% and the cover rate got 50%. This fact proved that Vetiveria zizanionides could grow in the poisonous waste mine.更多还原
