Method for rapidly recovering slope vegetation

Abstract

The invention relates to a method for rapidly recovering slope vegetation. The method comprises the following steps that 1, the slope surface is prepared; 2, net hanging is conducted; 3, rivet reinforcement is conducted; 4, vegetative plate erecting is conducted; 5, base material spraying is conducted; 6, seed layer spraying is conducted, wherein to-be-sprayed plant seeds are a mixture of seeds ofpioneer species, constructive species and a ground cover, the seeds are mixed according to the proportions of 20-100 g/m<2> of pioneer species, 20-60 g/m<2> of constructive species and 10-30 g/m<2> of ground cover, the pioneer species adopt annual or biennial herbaceous plant seeds, the constructive species adopt shrub or small tree seeds, and the ground cover adopts cold season grass seeds and warm season grass seeds for mixed sowing; 7, non-woven fabrics are used for covering. Accordingly, on the premise that an existing technical process is not changed, and the construction cost is not increased, the better slope vegetation recovery effect if obtained, and rapid forming and sustainable development of the target community are promoted.

Description

technical field [0001] The invention relates to a method for quickly recovering slope vegetation. Background technique [0002] During the construction of the expressway, the mountain body was excavated, and a large number of exposed high and steep slopes were formed along the temporary sidewalk of the wind farm. These slopes have the following characteristics: [0003] (1) The slope is steep, and it is not suitable for people to plant on the slope. The slope of most slopes is i>1:1, some even reach i=1:0.75, some reach i=1:0.5 or more. On this kind of steep slope, people can hardly stand stably, it is not suitable for planting operations on the slope, and the planting of plants is also unstable, and it is difficult to restore vegetation on high and steep slopes. [0004] (2) The soil layer on the slope is thin, so it is not suitable to plant plants directly on the slope. The formation of a stable steep slope requires high compactness of the soil on the slope, but ope...

Problems solved by technology

On this kind of steep slope, people can hardly stand stably, it is not suitable for planting operations on the slope, and the planting of plants is also unstable, and it is difficult to restore vegetation on high and steep slopes

[0004] (2) The soil layer on the slope is thin, so it is not suitable for planting plants directly on the slope

The formation of a stable steep slope requires high compactness of the soil on the slope, but operations such as excavating planting holes and covering soil when planting plants on the slope seriously damage the compactness of the slope soil and make the slope unstable.

[0005] (3) The vegetation restoration project on high and steep slopes has almost no maintenance and management conditions in the later stage

[0006] Based on the above reasons, the commonly used technical measure for vegetation restoration on high and steep slopes i...
