传统的绿化方法对高等级公路开挖后裸露的岩质边坡难以直接绿化。喷混绿化新技术利用特制喷混机械将土壤、肥料、有机质、保水材料、植物种子、水泥等混合干料加水后喷射到岩面上 ,由于水泥的粘结作用 ,上述混合物可在岩石表面形成一层具有连续空隙的硬化体 ,种子可以在空隙中生根、发芽、生长 ,而一定程度的硬化又可防止雨水冲刷 ,从而达到恢复植被、改善景观、保护环境的目的 The traditional greening method can not directly green the bare rock slope after high-grade highway excavation. Spraying new greening technology Spraying soil, fertilizer, organic matter, water retaining material, plant seeds, cement and other mixed dry materials with water on a rock surface using a special spray-mixing machinery, the mixture can be formed on the rock surface due to the cementing effect A layer of hardened body with continuous gaps, the seeds can root in the gap, germination, growth, and to some extent, but also to prevent hardening of the scouring, so as to restore vegetation, improve the landscape, the purpose of environmental protection
