Tree and grass planting member for preventing and fixing sand

Abstract

The present invention relates to one kind of tree and grass planting member for preventing and fixing sand. The member is one barrel with closed upper end and through hole in the closing end. It is simple in structure, low in cost, no liability of being damaged, pollution-less and reuseable. It may be spread in large range including the back land of desert to block the contact between wind and sand, control the sand of storm and tackle desert fast. Inside the member, tree or grass may be planted to restore vegetation and improve ecological environment quickly.

Description

technical field [0001] The invention relates to a component for planting trees and grass for sand prevention and control. Background technique [0002] Natural disasters such as land desertification, continuous shifting of sand dunes, and frequent sandstorms have seriously affected people's lives and threatened human survival. Therefore, it is urgent to prevent and control desertification and eliminate the hazards of sand and dust. [0003] The key to desertification is dry climate, wind erosion of land and sand flow. At present, people mainly adopt biological sand control and barrier sand control to curb the process of desertification, and some results have been achieved. However, due to the vast desert area, harsh ecological environment, and poor atmospheric and soil moisture conditions, the requirements for biological sand control are relatively high, and the effective cycle is long, sand control is difficult, and implementation is limited; while barrier sand control is...

AI Technical Summary

Problems solved by technology

However, due to the vast desert area, harsh ecological environment, and poor atmospheric and soil moisture conditions, the requirements for biological sand control are relatively high, and the effective cycle is long, sand control is difficult, and implementation is limited; while barrier sand control is basically It is manual operation, which is labor-intensive and slow in progress. It cannot go deep into the desert hinterland to quickly and efficiently prevent wind and sand damage, nor can it resist the erosion of the surface by wind and sun and the evaporation of surface water (it mainly uses grass products)
