Abstract

The invention provides a vegetation recovery method for soil-free gravel surface. The vegetation recovery method is characterized by comprising base hydro seeding and planting layer hydro seeding. Inthe base hydro seeding, a spray seeding matrix is injected into gravel gaps to fill the gaps. In the planting layer hydro seeding, the thickness of the spray seeding matrix is 2.5 to 4 cm. In the soil-free gravel surface, the covering thickness of gravel is 0 to 30 cm. For the slope of slag and gravels with a thickness of less than 30 cm, the materials disclosed by the invention have high adhesionafter hydro-seeding is carried out on the gravel gaps, so that the loss amount of the materials is obviously reduced.

Description

technical field [0001] The invention relates to a method for protecting slopes, in particular to a method for restoring soilless gravel surface vegetation, and belongs to the technical field of environmental protection. Background technique [0002] With people's continuous understanding of the importance of the ecological environment, environmental protection and restoration of the damaged ecological environment have become important research topics for those skilled in the art. For slopes covered with slag and gravel; for example, slopes on both sides of roads and railways, there is currently no good vegetation restoration method. [0003] For this type of slope, the surface layer is slag and gravel with a thickness not greater than 30cm, and the inner layer is still soil. For this kind of slope, it is neither directly covered with foreign soil like the soil slope, nor completely free of soil like the rocky slope. The characteristics of this kind of slope are: the surfac...
