摘  要:
草本植物混播应用于高等级公路边坡防护,具有减少噪音、防冲减蚀和改善公路沿线生态环境的良好效果。播种当年地表植被覆盖度达89.5%以上,可分别减少径流、泥沙36.5%和82.7%以上,次年地表覆盖度可达95%以上,基本上无水土流失且对土壤的改良作用明显。其中百喜草(50%)+白三叶(50%)的效果最好,高羊茅(40%)+白三叶(40%)+多年生黑麦草(20%)的效果次之,多年生黑麦草(30%)+早熟禾(30%)+白三叶(40%)的效果居第三。

摘  要:
Applying mixed planting of herbs to the slope protection of higher grade highways has better results of reducing noise, preventing and reducing erosion and improving ecological environment along the highway. The rate of vegetation coverage of land surface can reach more than 89.5% and runoff and sediment reduction more than 36.5% and 82.7% respectively in the same year of planting. In the second year, the rate of coverage of land surface can reach more than 95%, basically no soil and water loss and effects on soil improvement are remarkable. Among the grasses, the effect of Paspalum notatum (50%) + White Clover(50%) is the best, Lofty Fescuegrass(40%) + White Clover(40%) + Perennial Ryegrass(20%) ranks the second and Perennial Ryegrass(30%) + Annual Bluegrass(30%) + White Clover(40%) is the third.
