Device and method for comprehensively preventing wind, controlling sand and stopping desert

Abstract

The invention discloses a device for comprehensively preventing wind, controlling sand and stopping desert. The device comprises a hollow shell and a plurality of through holes arranged on the periphery of the shell, wherein the through holes are positioned on the upper part of the shell; the shell is made from degradable materials; the wall of the shell is provided with a pore; and the wall of the lower part of the shell is provided with a lateral fine hole. The invention also discloses a method for preventing wind, controlling sand and stopping desert by using the device. The method for comprehensively controlling sand of the invention which combines the advantages of plant controlling sand and engineering controlling sand and takes full advantage of the natural condition of desert, can comprehensively prevent wind, control sand and stop desert, is beneficial to the growing of plant, has no pollution to soil, has lower cost, is easy to expand in a wide scope, and can treat the desert interior land and treat the center of the sand resource.

Description

technical field [0001] The invention relates to the technical field of comprehensive wind prevention, sand control and desert control, in particular to a device and method for comprehensively utilizing plant sand control and engineering sand control technologies to control deserts. Background technique [0002] The key to desertification is dry climate, land wind erosion and sand flow. At present, people mainly use plant sand control and engineering sand control methods to control deserts. [0003] The main method of plant desertification control is to plant grass and trees for afforestation. The main point is to achieve the purpose of blocking wind and sand, fixing sand and stopping desert by forming vegetation. One of its disadvantages is that this method is only applicable to the edge of the desert, where there are conditions for planting grass and trees, and it cannot go deep into the hinterland of the desert and the center of the sand source, which is quite limited. ...

AI Technical Summary

Problems solved by technology

One of its disadvantages is that this method is often expensive (such as high material cost, repeated settings, labor-intensive, etc.), and it is difficult to promote it on a large scale.

The second disadvantage is that the materials used to set up sand barriers are generally cement, plastic, asphalt, etc., which pollute the land

The third disadvantage is that methods such as inserting hay often cannot improve the near-surface climate environment (cannot prevent the evaporation of water, cannot form a microclimate, etc.), plants are difficult to survive, and eventually fail after a long time, etc.

[0005] Taken together, the existing sand control methods are basically still on the surface of sand fixation and sand prevention, and there is no effective method that can achieve the following four goals at one time: 1. Comprehensively play the role of wind prevention, sand control and desert control ; 2. It is conducive to the growth of plants in deserts; 3. It has no pollution to the soil; 4. The cost is low and it is easy to promote on a large scale
