Problems solved by technology

[0005] The above-mentioned prior art is suitable for rocky mountain slopes with shallow soil layers and poor soil conditions, but due to its high engineering cost, it is not fully applicable to extremely steep loess slopes with deep soil layers and good soil conditions
In addition, this technology forms a shallow root layer of sprayed plants, which cannot effectively use deep soil moisture. Although the survival rate was very good in that year, the preservation rate after 3 years was low, especially in the Loess Plateau

specific Embodiment 1

[0049] In the Dajigou watershed of Wuqi County, Shaanxi Province, the extremely steep slope formed by the newly built mountain road was selected as the afforestation slope, with slopes ranging from 50 to 80°. The row spacing of perforated afforestation is 50×50cm, and the diameter of planting holes is 12cm. The overall perforation points are arranged according to the flow pattern. The afforestation tree species are Caragana Korshinskii Kom., Tamarix chinensis Lour., and Caryopteris clandonensis'Worcester Gold') is a planting tree species. First, pre-mark the position of each hole point according to the preset landscape configuration, and count the number of afforestation tree species according to the number of punch points and landscape requirements; then, use a punching machine to punch perpendicular to the slope according to the location of the layout. Hole with a depth of 40cm, then follow the steps below to complete afforestation in sequence:

Abstract

The invention discloses a method for afforesting an abrupt slope by punching. The method comprises the following steps: firstly, determining number and specification of holes to be punched on a slope surface for afforestation, and arranging locations of punching points for afforestation; then punching planting holes vertical to the slope surface according to the arranged locations of the punching points, wherein, a dry soil layer of the slope surface needs to be broken; and finally afforesting by sowing coated seeds, planting container seedlings or planting deep-root container seedlings. The method disclosed by the invention has the beneficial effects that by adopting a punching implanting technology, the dry soil layer of surface soil of the abrupt slope is broken so that a plant root system in the abrupt slope can absorb moisture in deep soil, thus slope fixation and protection are guaranteed, and meanwhile vegetation storage rate and plant growth stability are improved so as to effectively solve the bottleneck problem of poor stability of abrupt slope landscape engineering.

Description

Technical field [0001] The invention relates to a method for afforestation and greening of slopes, in particular to a method for afforestation and greening of extremely steep slopes. Background technique [0002] The steep slopes formed due to natural or man-made reasons have low soil water content, very sparse vegetation, and serious soil erosion. They have become one of the main sources of effusions, overhangs, collapses, and landslides. [0003] On steep slopes, vegetation coverage is low, and biological soil crusts formed by lichens and mosses are the main form. There are few deep-rooted shrubs and trees. The soil mainly relies on its own cohesion to keep the slope stable. It is extremely easy to form gravitational erosion such as diarrhea, suspension ditch, collapse, slumping, and even provide conditions for the occurrence of mountain disasters such as mudslides. [0004] In the prior art, spraying technology or various greening technologies based on spraying technology are the...
