Rapid and lasting re-greening method for high and steep rocky slope vegetations

Abstract

The invention discloses a rapid and lasting re-greening method for high and steep rocky slope vegetations. The method comprises the following steps: (1) shaping and checking a slope surface, and removing dangerous rocks; (2) paving a protective net along the whole slope surface from top to bottom, fixing the protective net on the slope surface by adopting grouting anchor rods, and arranging transverse and longitudinal ecological belts between the protective net and the slope surface; (3) casting V-shaped planting grooves in situ in the slope surface; (4) spraying a slope matrix layer onto theprotective net, fixing a coconut fiber net on the matrix layer by using U-shaped nails, and spraying and sowing an organic material mixed with grass seeds on the coconut fiber net; and (5) backfillingsoil in the V-shaped planting grooves, and planting vine plants and shrubs. Through the synergistic effect of the ecological belts, the planting grooves and the hanging net spraying and mixing technology, the defects that in a conventional greening technology, a base material is easily scoured, the greening effect is slow, greening is not uniform, and the re-greening effect is difficult to last are overcome, by arranging the planting grooves and the ecological belts, the stability of the side slope is improved, lasting nutrient supply is achieved, and rapid and lasting re-greening of high andsteep rocky slopes can be realized.

Description

technical field [0001] The invention relates to the technical field of regreening of mine slopes, in particular to a method for rapid and long-lasting regreening of vegetation on high and steep rocky slopes. Background technique [0002] In the construction of highways, railways, mines, and water conservancy projects, a large amount of earthwork excavation is often accompanied, which destroys the original ecological environment and causes a large number of exposed slopes, resulting in serious soil erosion and ecological environment imbalance. Due to the slopes formed by these projects, it takes a long time to restore the ecological balance by the power of nature itself, and it is basically impossible to restore the high and steep rocky slopes, so engineering measures need to be taken to protect them And ecological greening treatment to prevent slope damage, soil erosion, and water conservation, air purification, beautify the environment. [0003] At present, the common meth...

Problems solved by technology

[0004] In order to solve the problems existing in the existing high and steep rocky slope regreening, the purpose of the present invention is to provide a fast and long-lasting regreening method for high and steep rocky slope vegetation. The synergistic effect of mixed technology overcomes the disadvantages of conventional greening technology that the base material is easily washed away, the greening effect is slow, the greening effect is uneven, and the regreening effect is difficult to last. By setting up planting grooves and ecological belts, the stability and durability of the slope are improved. The nutrient supply can realize rapid and long-lasting regreening of high and steep rocky slopes
