Abstract

The invention belongs to the technical field of land desertification treatment, and particularly relates to a method for effectively preventing land desertification. By means of the method, it is effectively guaranteed that land is not desertified, soil can be improved, the soil structure and environment are improved, water and soil desertification, salinization and crust forming are reduced, organic matter and cationic cellulose-polyacrylamide copolymer are rich, high water absorption and retention performance and good inorganic salt tolerance are achieved, the survival rate of a land cover is increased, plant growth is promoted, economic benefits are increased, desertification treatment is promoted, and the method is scientific, reasonable, environmentally friendly, safe, free of toxin and harm and free of secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of desertification control, in particular to a method for effectively preventing land desertification. Background technique [0002] The process of desertification development and reversal is the result of interaction and coordination between human activities and natural environment and resources. Desertification is the result of the interaction between man and nature. In the prevention and control of desertification, it is necessary to fully consider reducing the pressure of human beings on the ecological environment, but also conform to its natural development law and improve the production potential of resources, and pay attention to the necessary human and material resources to increase the carrying capacity of land per unit area. In the process of prevention and control, gradually improve the relationship between man and nature, making it gradually harmonious and harmonious. Controlling sand and preve...
