Slope greening is an important ecological project, which can not only improve the landscape effect, but also effectively enhance the self-recovery ability and biodiversity of the ecosystem. Spraying greening method is one of the main methods of slope greening.

This method is suitable for various types of slopes, especially steep and difficult to climb slopes. The ratio of the spraying substrate and the thickness of the spraying are key contents, especially the thickness control of the spraying substrate is the main factor determining the later vegetation growth. At present, the thickness of the spraying is generally controlled subjectively by the construction workers according to their own experience during the construction process. The technical levels of the workers are uneven, resulting in insufficient spraying thickness, which requires re-spraying, increasing secondary costs, or too high spraying thickness, resulting in waste of materials.
