摘要
通过室内模拟试验和具体工程实践应用,研究了绿化喷播技术在植被恢复和护坡工程中的应用。该技术主要利用特有的喷播组合机械将土壤、有机质、保水材料、植物种子、粘接材料、长效肥料等混合干料加水后直接喷射到岩面上,在一定的养护条件下,灌木和草本种子可以在空隙中生根、发芽、生长,为植物的生长和自然演替创造更为有利条件,从而达到快速恢复植被、改善景观和保护环境的目的。实践证明:该项技术可以解决高陡岩土坡面植被恢复难题,有利于景观恢复,减少坡面水土流失,对于生态保护和经济可持续发展具有重要意义。
The application of seeding spraying technology in vegetation restoration and slope protection project was researched by simulated experiment in Lab and engineering practice. The technology is first to add water to mixing materials such as soil, organic matter, superabsorbent polymers, plant seeds, cementing material, longlasting fertilizer and so on, then to spray them on rock surface directly by using current spraying combination machine. Under a certain nurture condition, the seeds of shrub and grass can take roots, germinate and grow in these gaps. Thus the purposes of restoring vegetation, improving landscape, protecting environment are gained. The practice showed that the technology can resolve the problem that vegetation restoration is considered to be hardly possible in high slope of rock. It is useful to restore sight, and to decrease soil loss in slope. It is very important to ecological protection and economic sustainable development.
