Method for planting vegetation on the karst area slope

Abstract

The invention discloses a method for planting vegetation on the karst area slope, comprising: laying and fixing a wave shape plant-growing net with meshes on the slope surface, wherein the wave shape plant-growing net can be formed by connecting a surface layer net and a wave shape net and also can be formed by connecting the surface layer net, the wave shape net and the bottom layer net; spraying the artificial soil for the shrub slope protection in the karst area on the wave shape plant-growing net by a mechanical or an artificial operation method, and spraying the plant growth substrate mixed with the plant seeds on the top of the artificial soil by a sprayer. The invention lays the wave shape plant-growing net with the meshes on the shrub slope protection in the karst area, therefore,the sprayed artificial soil and seeds during laying the planting substrate can absorb in the wave shape plant-growing net with the meshes. The invention provides an adhesion platform for the artificial soil and seeds to ensure the root system expansion during plant growth, promotes the construction speed and saves the construction cost.

Description

technical field [0001] The invention relates to a method for planting vegetation, in particular to a method for planting vegetation on slopes in karst areas. Background technique [0002] Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and the accompanying mechanical action. Karst landforms are widely distributed in Guangxi, Guizhou, Yunnan and other places in China. In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rock and soil slopes that cannot be restored to vegetation. It is almost impossible to restore vegetation coverage naturally on the surface in a short period of time; The existing slope engineering reinforcement measures mostly pursue strength and efficiency, and mostly adopt gray protection such as stone masonry and shotcrete, which destroys the harmony of natural ecology. With people's emphasis...

AI Technical Summary

Problems solved by technology

But above-mentioned method also has the following problems in karst area popularization, 1 karst area slope surface gradient is bigger, the characteristic that rock is more, existing technical method is carried out vegetation on karst slope, can't vegetation be adsorbed tightly on the slope surface, Or although it can make the vegetation adsorb on the slope, it can't make the vegetation grow better; 2. In the practical process, there are still problems such as slow construction speed, high cost of artificial soil, slow production speed of nutrient substrate, dangerous construction, and uneconomical and applicable problems.
