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
