Method for greening high precipitous rock slope

Abstract

The invention discloses an afforestation method of a steep rocky slope, relating to an afforestation method. The invention comprises that: 1. an afforestation system consisting of the steep rocky slopes (1), gentle slope belt casing soil (2) arranged on the steep rocky slope, water gathering slots (3) that connects from top to bottom in sequence, an impounding reservoir (4) and a irrigation pipeline (5), wherein, the water gathering slots (3) are arranged at the middle part of a water gathering plane of the steep rocky slope (1); 2. climbing vegetation and/or hanging vegetation (6) is planted on the gentle slope belt casing soil (2), covering the steep rocky slope (1); 3. mixed vegetation of tree, shrub and fodder grass (7) is planted on the gentle slope belt casing soil (2). The invention applies ecological afforestation to the steep rocky slope (1), uses a mixed wood mode to increase the survival rate of the climbing vegetation and the hanging vegetation and adopts a natural irrigation system to reduce the maintenance cost or with a view that no maintenance cost is needed, thereby being applicable to the afforestation of the steep rocky slop (1).

Description

technical field [0001] The present invention relates to a greening method, in particular to a greening method for high and steep rocky slopes; in particular, it relates to a greening method for high and steep rocky slopes in abandoned mine stopes, which is suitable for various abandoned quarries High and steep rock slope greening fields formed by fields, mines, water conservancy, transportation, municipal, civil engineering and other projects. Background technique [0002] At present, the commonly used greening methods for rocky slopes at home and abroad include guest soil spraying method, vegetation belt (pot, bag) method, three-dimensional grid method, concrete frame beam method, thick layer substrate spraying vegetation greening, vegetation concrete Greening, fish scale pit excavation technology, planting groove technology, climbing plant greening and other methods. [0003] Can be divided into two categories: alien soil method and climbing vegetation method. [0004] T...

AI Technical Summary

Problems solved by technology

[0004] The guest-soil method is only suitable for slopes with a slope below 60 degrees, and it is expensive, high maintenance cost, difficult to fix the base material, vegetation is not drought-tolerant and soil is poor, vegetation water and fertilizer supply is insufficient, and the long-term greening effect is not satisfactory. to guarantee;

[0005] Although the vertical greening effect of the climbing vegetation method is good, it faces the problem of not being evergreen, and the early effect is not good, the landscape is single, and the level is not good. It is mainly used for vertical greening in some cities
