Three-dimensional desert sand stabilization net made of straws

Abstract

The invention discloses a three-dimensional desert sand stabilization net made of straws. The advantages of physical sand stabilization and biological sand stabilization are organically combined, the sand stabilization effect is improved, and the three-dimensional desert sand stabilization net is more environment-friendly. The three-dimensional desert sand stabilization net is composed of single body joints. The single body joints are manufactured by compacting the straws and have certain structural strength, and a three-dimensional net structure can be formed after the single body joints are connected and used for physical sand stabilization. Seeds are arranged in the centers of the single body joints. The single body joints have certain water absorption capacity and can become seed culture soil. As time goes by, the single body joints are gradually degraded, the seeds germinate and grow, and physical sand stabilization is converted into biological sand stabilization.

Description

technical field [0001] The invention relates to a desert sand-fixing net used in the environmental treatment process, in particular to a desert sand-fixing net made of straw. Background technique [0002] At present, the desertification of cultivated land in the world is still happening. Desertification will bring multiple problems, involving life, production and other aspects. As a good way to prevent the spread of deserts and prevent desertification, sand fixation has a large number of applications in various places. Currently, there are two ways of sand fixation: biological sand fixation and physical sand fixation. Bio-sand fixation mainly uses the root system of plants to fasten sandy soil. The disadvantage is that the first installation requires a lot of manpower and financial resources, maintenance is inconvenient, and it takes years to take effect. Physical sand fixation mainly uses sand-proof nets to reduce the fluidity of sand and soil. The disadvantage is that m...

Bio-sand fixation mainly uses the roots of plants to fasten sandy soil. The disadvantage is that the first installation requires a lot of manpower and financial resources, maintenance is inconvenient, and it takes years to take effect

Physical sand fixation mainly uses sand-proof nets to reduce the fluidity of sand and soil. The disadvantage is that most of the sand-proof nets use plastic substrates, which are difficult to degrade and cause secondary damage to the environment.
