Desertification soil treatment method

Abstract

The invention provides a desertification soil treatment method. The desertification soil treatment method comprises the following steps that a vegetation zone formed by alternately laying and planting ecological vegetation carpets and protection forests is laid on desertification soil along the border between the desertification soil and vegetation towards a desert; a wood retaining wall is erected on the vegetation zone; ecological vegetation ditches and a water storage tank are formed, and supporting wood plates covered with ecological vegetation carpets are laid on the ecological vegetation ditches and the water storage tank; a water pipe provided with spray nozzles is laid, the water pipe is connected with a water pump, and a pumping pipe of the water pump extends into the water storage tank; following management and maintenance are conducted on the laid vegetation zone. By the adoption of the desertification soil treatment method, the desertification soil treatment effect can be achieved by executing the desertification soil treatment method once, after grass seeds and protection forest plants grow well, the texture of the desertification soil can be fundamentally changed, treatment is thorough, and devices used during treatment can be detached and recycled. According to the desertification soil treatment method, effectiveness can be achieved quickly, the period is short, operation is easy, the treatment cost is low, the rate of survival of planted vegetation is high, and the planted vegetation is easy to manage and maintain in the later period.

Description

technical field [0001] The invention relates to a desertification soil control method, which belongs to the field of soil desertification control. Background technique [0002] At present, climate warming and precipitation reduction have exacerbated the aridification of climate and soil in Northwest China. This reduces the vegetation coverage in this area, and the soil structure becomes looser, which accelerates the desertification of the land. In addition, the warming of the climate and the continuous drought of the large-scale climate have seriously affected various water resources (glaciers, lakes, rivers, etc.), causing glaciers to retreat, rivers to reduce or stop flowing, lakes to shrink, and groundwater levels to drop. A large area of ​​vegetation died due to lack of water, which lost the function of protecting the surface soil and accelerated the speed of soil desertification. [0003] The existing method of desert control mainly adopts afforestation, but this meth...

Problems solved by technology

[0004] The Chinese patent "A Method for Controlling Deserts" (Patent No.: CN02130859) discloses a method for controlling deserts, which uses artificial turf to cut out planting holes, sprinkle soil in the planting holes and plant plants, so as to retain water , sand fixation, and greening, but the cost of using artificial turf is high, and the artificial turf needs to be replaced regularly, which will affect the growth of plants. Planting plants in planting holes has low planting density, and it is difficult to guarantee the survival rate of plants.
