Slope collapse jetting forestation method

Abstract

The invention discloses a slope collapse jetting forestation method. The slope collapse jetting forestation method comprises the following steps of: firstly, selecting indigenous plant seeds agreeable to the local place, mixing the seeds with soil, fertilizers, water and chopped straws to form mud; and then coating or jetting the mud points on the surface of an abrupt slope cliff of slope collapse by a hand or a liquid jetting gun according to a needed density during the rainy season, so as to finish a slope collapse tree planting and grass planting process. The method disclosed by the invention effectively eliminates and reduces a mountain collapsing phenomenon caused by gravity corrosion, overcomes the disadvantages of high cost, great construction difficulty and poor construction safety of planting trees and grass on a traditional slope collapse slope surface, and has the advantages of strong practicability, simple method and obvious environment-friendly effect; landscape ecology of the slope collapse slope surface is effectively enriched and the improvement of a slope collapse ecological environment is accelerated; and the slope collapse jetting forestation method is particularly applicable to being popularized and used in a slope collapse comprehensive treatment process of wide red earth hilly areas.

Description

technical field [0001] The invention relates to a method for afforestation on collapsed hills, in particular to a water and soil conservation method for afforestation on slopes of collapsed hills by means of artificial spraying, and belongs to the technical field of artificial forestation. Background technique [0002] Collapsing hillside refers to the erosion phenomenon of hillside soil or rock weathering crust decomposing, collapsing and accumulating under the action of water force and gravity. It is a special form of gully erosion and mostly occurs in tropical and subtropical regions in southern my country. The harm caused by the collapse of hillock erosion is manifested in: destroying land resources, destroying basic farmland and other public transportation facilities, exacerbating the occurrence of natural disasters such as floods, droughts, and mudslides, deteriorating the local living environment, threatening the safety of people's lives and property, and eventually le...

Problems solved by technology

[0003] Due to the steep slope of the collapsed hill, it continues to collapse under the action of gravity, which is harmful to the environment and human beings. At the same time, the vegetation on the slope after the collapse is difficult to grow, resulting in a large area of ​​exposed ground, forming a poor-quality landscape, which has become a difficulty in landscape ecological restoration.

[0004] In order to reduce the damage of gravity erosion and improve the surface landscape, scientists have carried out a series of research work, such as: building drainage channels on the upper slope of the collapsed hill to prevent the formation of confluence on the upper slope to scour the collapsed slope; drilling on the exposed slope of the collapsed hill Hole afforestation, planting grass, and reducing soil erosion on slopes, etc., have played a certain role in preventing and reducing soil erosion, but all these methods have high cost and low greening efficiency, especially in the field environment, the construction is difficult and difficult. The safety is poor, which brings serious adverse effects on large-scale afforestation and slope protection
