Problems solved by technology

However, this method is more suitable for regreening slopes with gentle slopes, and the pit surface and pit bottom lack adaptive changes. The root system of seedlings in the early growth stage is underdeveloped, and the demand for soil space is small. The demand for soil space increases, and at the same time, the amount of guest soil filled in pits in mining areas is small, which is not conducive to the growth and development of seedlings
In order to provide a sufficient guest soil environment, it is usually necessary to dig a large pit, which requires a large amount of soil and high cost

Abstract

The invention discloses an ecological greening method for a mine steep slope surface. The method comprises the following steps: loose and protruding soil is finished to achieve the effect of cleaningthe slope surface; planting holes are dug on the slope surface, and are convex; a net is hung on the slope surface between the planting holes, and is fixed with anchor rods after being hung; perforated cylinders are arranged in the axial direction of the planting holes, the planting holes are filled with pastoral soil, and the perforated cylinders are filled with nutrient substrates; cement is poured into the planting holes filled with pastoral soil, and sowing holes are reserved on a cement pouring layer; Hexinia polydichotoma is sown in the planting holes by the sowing holes, sufficient water is poured, and then soil coverage is performed. After construction by the ecological greening method, the slope is stable, no landslide or collapse occurs within two years after construction is completed, the soil in the holes remains intact, no rain erosion and loss occurs, and the slope has high plant coverage rate, vibrant plants and excellent landscape effect.

Description

technical field [0001] The invention belongs to the technical field of slope regreening, and in particular relates to an ecological regreening method for steep mine slopes. Background technique [0002] Slope regreening refers to the ecological slope protection method that uses plant seeds, seedlings, etc. to be planted on the slopes of structures such as mines and river embankments to protect the stability of the slope and beautify the environment. It is different from the traditional civil engineering slope protection (reinforced anchor Pole support, hanging nets, grids, etc.) can effectively realize the restoration and protection of ecological vegetation on slopes. It not only has the function of maintaining water and soil, but also can improve the ecological environment and landscape, and improve the level of ecological vegetation restoration. Infrastructure construction and mining resource development have formed a large number of exposed slopes. These exposed slopes no...
