摘  要:
研究了3种混播组合对高速公路边坡的防护效益,结果表明:混播组合方案1(红豆草60%+无芒雀麦20%+多年生黑麦草20%)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20%+草地早熟禾50%+高羊茅30%),减少径流80.9%,减少冲刷80.9%;而混播组合方案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%。

摘  要:
Three seed mixtures included 1) 60 % Onobrychis viciaefolia,20 % Bromus inermis and 20 % Lolium perenne;2) 70 % Cornilla varia and 30 % Lolium perenne;3)(20 %) Lolium perenne,(50 %) Poa pratensis and(30 %) Festuca rubra,were evaluated for turf established along highway roadsides.The results indicated that the first mixture was the best one for preventing soil erosion.Compared with bare area,the surface run off 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.
