Description

technical field

[0001] The invention belongs to the technical field of crops, and in particular relates to a method for controlling desertification land. Background technique

[0002] my country is a large grassland country with 6 billion mu of various types of natural grasslands, accounting for 41.7% of the land area and 13% of the world's total grassland area. Grasslands are renewable natural resources with multiple functions. It plays an important role in maintaining the global ecological balance; because the grassland ecosystem has been affected by both natural and human interference factors for a long time, especially unreasonable human interference, 80% of my country's usable grasslands have appeared in varying degrees. Three modernizations" (degradation, desertification, salinization). Although the treatment is carried out, there is still a phenomenon of "partial treatment and overall expansion", which makes the load on the grassland more and more heavy, the productivi...
