Desertification land treatment method and treatment structure

Abstract

The invention provides a desertification land treatment method and structure, and the treatment method comprises the steps: the surface layer of an undisturbed sandy soil layer of a to-be-treated area is covered with sludge, the sludge contains reservoir sludge, and the upper layer of the sludge is doped with vegetation seedlings or grass seeds, so that an organic matter layer is formed on the upper layer of the sludge, and a sedimentary layer is formed on the lower layer of the sludge; plants are planted on the organic matter layer. According to the desertification land treatment method and the desertification land treatment structure, wind prevention and sand fixation can be effectively achieved, water evaporation of undisturbed sandy soil is slowed down, the water binding capacity and fertility of the desertification land are improved, the soil forming process of the undisturbed sandy soil is accelerated, and soil conditions and physical conditions beneficial to growth and development of vegetation are provided. In a further scheme, the plant-cutting composite sand barrier is improved through reservoir sludge, germination and breeding of vegetation are promoted, and the windproof effect of the sand barrier can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sandy land control, in particular to a sandy land control method and a control structure. Background technique [0002] Land desertification will lead to soil degradation and wind and sand flow, which in turn will lead to ecosystem degradation and loss of land resources. The task of desertification land management is very urgent. [0003] In the prior art, desertified land treatment usually adopts biological sand fixation, chemical sand fixation and mechanical sand fixation in the desertified area to be treated to increase vegetation coverage, improve soil performance, and finally improve the water retention and fertilizer retention of sandy land. [0004] However, these treatment methods failed to completely improve the quality of desertified land, and the soil composition is still dominated by aeolian sand, which is easily damaged by wind erosion and forms quicksand again. The dry and barren soil envir...

Problems solved by technology

[0004] However, these treatment methods failed to completely improve the quality of desertified land, and the soil composition is still dominated by aeolian sand, which is easily damaged by wind erosion and forms quicksand again.

The dry and barren soil environment is an important factor restricting desertification land governance. Vegetation seedlings have high requirements for water and nutrient supply and maintenance during the growth period, and the survival rate in the desertification land environment is low, and the effect is slow and the cycle is long
