Embodiment approach

[0039] As an embodiment of the present invention, the sodium carboxymethyl cellulose is distributed in circular dots on the surface of the soil layer, and the diameter of the circle covered by the sodium carboxymethyl cellulose on the soil layer is 0.2-0.5m; The sand barrier is buried in a grid shape with a length of 1.2-2.5m, and surrounds the circumferential direction of the sodium carboxymethyl cellulose covered on the surface of the soil layer; in the desertification soil control process, chemical sand control cementing materials and The sand barrier buried in engineering sand control consumes a lot in the vast soil area, and the life of the buried sand barrier is also limited; by making the cementing material of sodium carboxymethyl cellulose in the surface of the treated soil distribution, and with the sand barrier squares buried in its circumferential direction, it reduces the amount of chemical cementing materials and increases the area of ​​sand barrier squares, and us...

Abstract

The invention relates to the technical field of soil treatment, in particular to a desertified soil treatment method. The method comprises the steps of data collection, environment measurement, soil layer remediation, inspection maintenance and process analysis. Due to the fact that an existing desertified soil treatment mode is single, and meanwhile, a simple accumulated comprehensive treatment mode is carried out, the treatment effect of the mode is still limited; and therefore, the survival condition for treating initial biological soil crust is ensured through spraying and water supplementing measures in inspection maintenance, partial consolidation and water storage performance of the soil layer is recovered by matching with laid sunshade nets and sand barriers and assisting the modification effect of sodium carboxymethyl cellulose on the soil layer, then the engineering sand stabilization method and the chemical sand stabilization method are combined, the success rate of biological desertification control is increased, continuously covered vegetation is formed in the desertified soil, and optimal treatment measures are deployed by combining water supplementing in inspection maintenance and recording and analysis in the treatment process, so that the application effect of the desertified soil treatment method is stabilized.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a desertification soil treatment method. Background technique [0002] Desertified soil is defined as land degradation in arid, semi-arid and sub-humid dry areas caused by various factors including climate variability and human activities; desertification in a broad sense actually includes wind erosion desertification, water erosion desertification, salinization, and freeze-thaw desertification Among them, the vast majority of desertification types in my country belong to wind erosion desertification. In recent years, probably due to the aggravation of smog weather, people's attention is mostly on PM2.5. , but in fact, a large amount of resources have been continuously invested in the control of desertified soil, including natural restoration measures, such as enclosing land for forestry and grass cultivation, etc., trying to eliminate the interference of human activities on...
