摘　　要：试验将 3种混播组合对高等级公路边坡的防护效益进行了初步研究。结果表明 :混播组合方案 1(红豆草 6 0 % +无芒雀麦 2 0 % +多年生黑麦草 2 0 % )的防护效果最好 ,减少径流82 .6 % ,减少冲刷 90 .1% ;其次是混播组合方案 3(多年生黑麦草 4 0 % +草地早熟禾 2 0 % +匍匐翦股颖 2 0 % +紫羊茅 2 0 % ) ,减少径流 80 .9% ,减少冲刷 80 .9% ;而以混播组合方案 2(小冠花 70 % +多年生黑麦草 30 % )的防护效果最差 ,减少径流 76 .4 % ,减少冲刷 73.5%Three seed mixtures by weight included (1) 60% common sainfoin, 20% awnless brome and 20% perennial ryegrass; (2)70% boxleaf coronilla and 30% perennial ryegrass; (3) 40% perennial ryegrass, 20% kentucky bluegrass, 20% stolonbearing bentgrass and 20% red fescuegrass were evaluated for utility turf establishment grown along highway roadsides. The results indicated that the first mixture was the best one for preventing soil erosion. Compared with bare area the surface runoff and erosion reduced by 82.6% and 90.1% for the first mixture, 76.4% and 73.5% for the second one, 80.9% and 80.9% for the third one.
