Problems solved by technology

At present, the method of sand prevention and control is the petrochemical method, that is, the sand surface is solidified. This method has high input costs and is not conducive to the growth of green plants in the desert.
There is also a method of netting to prevent wind and sand control. This method only has the effect of sand fixation and sand prevention, and cannot retain water and is not conducive to plant growth.
The common sand control method is to directly plant plants in the desert, but due to the strong wind erosion of sand grains, it is difficult to take root, and it is difficult to maintain water, so the survival and growth rate of plants are extremely low, which brings great difficulties to sand prevention and control projects. extremely difficult

Embodiment Construction

[0015] As shown in the picture, 1. plastic film, 2. sand, 3. strip-shaped film

[0016] 1. Laminating method

[0017] The film covering method is to use the internal pressure method to cover the film, that is, to fold the edge of the plastic film toward the inner side of the covered sand body, and the folding depth is 20-30cm. blown away, and the film is blown over and damaged, resulting in the failure of the film covering.

[0018] 2. Laminating form

[0019] The strip-shaped film is adopted, which is to cover one by one according to the length direction of the plastic film along the main wind direction. The length of the covering strip can be determined according to the convenience of construction. If the section is too long, it will cause difficulties and inconveniences in construction and post-management. There should be a certain distance between the two film-coated belts, generally 20-30cm, which is convenient for walking and later management.

[0020] 3. In-film cul...

Abstract

The present invention is one inwards pressing film coating method for preventing and controlling desertification. Plastic belts are covered onto sandy soil with some interval in between and belt ends are bent and pressed into sand. The said method can fix sand against wind blowing and maintain water for planting, and has excellent desertification preventing and controlling effect.

Description

technical field [0001] The invention relates to a method for preventing and controlling sand, in particular to a method for preventing and controlling sand by using a plastic film. Background technique [0002] The irrational activities of human beings and the continuous deterioration of the earth's ecology, especially the problems of deserts, sandstorms and desertification have seriously affected and threatened the survival of human beings and the sustainable development of economic society. In recent years, sandstorms have occurred frequently all over the world, and the phenomenon of desertification has become increasingly serious. It has become the number one enemy of human survival and development. How to eradicate deserts, sandstorms and desertification is a topic of the times and an urgent task in front of mankind. [0003] At present, countries all over the world have carried out a large number of desertification prevention and control activities, and my country's dev...
