公路边坡草地建植技术及其护坡效果

介绍了公路边坡的狗牙根、百喜草护坡建植技术及护坡效果。这两种草护坡效果较好，它们耐旱耐瘠，根系发达，生长快，在建植过程中配合特殊的种植栽培技术，种后１０ｄ左右即可出苗，３个月之后能有效地减少土壤冲刷６７８％，坡面切割密度也由原来的７１％下降到１８％，不但绿化了公路边坡，美化了环境，而且降低了公路建设的成本

The Grass Planting Technology for Highway Slope Lawn and Its Function in Slope Protection.\

The technology of planting Bemorda and Bahia grasses on highway slopes and the function of slope lawn in slope protection were studied. The results of the study show that the two species of grass have strong drought and poverty hardiness, well developed root systems and fost growing speed. By adopting special planting technology, grass seedlings started to emerge only about 10 days after seeding, and within three months the soil erosion had been reduced by 67.8%, the slope surface cut density had been reduced from 71% to 18%. It is concluded that highway slopelawn could green and beautify the slope as well as reduce the construction cost of highway.
