Cultivatable organic treatment method for desert

Abstract

The invention relates to a cultivatable organic treatment method for desert, and belongs to the technical field of desert treatment. According to the technical scheme, common sand and stearic acid aremixed by using a physical method, and the weight ratio of the common sand to stearic acid is 20:0.5-20:5; the prepared mixture is taken as ideal sand; the ideal sand and sand on a desert needs to beimproved and treated are uniformly mixed, the mixed sand is thrown to the surface of the desert needs to be improved and treated, and the thickness is 20-40 centimeters; the weight ratio of the sand on the desert needs to be improved and treated to the ideal sand is 100:20-100:180. The method has the advantages of high practicability, high pertinence, high performance cost ratio, a wide application prospect and the like, the effect of transforming original sand land into cultivated land is achieved, if the method can be applied and popularized in a large scale, deserts can be effectively treated and transformed into the cultivated land and oases, and benefits can be brought to posterity.

Description

technical field [0001] The invention relates to an organic treatment method for arable desertification, which belongs to the technical field of desert control. Background technique [0002] China is one of the countries with the most severe desertification in the world, with a desertified land area of ​​2.64 million km 2 , accounting for 27.5% of the country's land area, among which the desert is the most serious hazard, and its area has reached 809,000 km 2 , and is still expanding, with an average of 610km per year 2 The left and right deserts are activated, of which 310km 2 The land was reduced to sand. Desertification has caused an imbalance in the ecosystem, and the area of ​​arable land has been shrinking, which has had a serious impact on industrial and agricultural production and people's lives. The desert and desertified land in the arid region of Northwest China have become one of the main sources of dust storms in China and even in the Asia-Pacific region, cau...

Problems solved by technology

However, a set of mature and complete practical technical methods for desert control has not been explored. The existing methods mainly include: planting trees to fix sand, meshing sand sealing, adding clay to improve, etc., but none of the above methods can effectively increase the moisture content of sandy soil. Loss of nutrients cannot be avoided
