Problems solved by technology

[0009] In order to meet the defects of the prior art, the present invention uses the solid waste produced by coal power plants that exist in large quantities in deserts or dry areas to prepare planting sand, and utilizes the water retention rate of planting sand as high as 60% to cover the desert to form an effective barrier. water layer, reduce water loss, plant crops in desert areas, and solve the defects in the existing methods of controlling desert environments

Abstract

The invention provides a method for governing desert by means of planting sand. The method comprises the steps that 1, the planting sand is soaked with water till saturation; b, 5-30 cm thick water retention planting sand is laid on a sand land; c, a 1-10 cm thick solidification material and surface active agent mixture is sprayed, and a 0.2-2 cm thick cross-linking agent is sprayed. According to the method, solid waste is adopted as a main raw material, the cost is low, the water adsorption is good, and the water retention rate is high, the solidification rate is controllable, the material can be degraded, no potential pollution exists, and construction is convenient.

Description

technical field [0001] The invention relates to a desert control and sand-fixing method, in particular to a method for using planting sand to control desert. Background technique [0002] Deserts refer to barren areas where the ground is completely covered with gravel, with very few plants, little rain, and dry air. It has always been regarded as the "cancer of the earth". Desertification is one of the most serious ecological and environmental problems in my country. The existing desertified land in China is about 1.689 million km 2 , accounting for 1 / 4 of the country's area, the desert area is about 521,200 km 2 , the Gobi area is about 730,700 km 2 , the land area eroded by wind is about 43,000 km 2 . [0003] Desert governance is still a serious problem facing the whole human being. It is the common goal of all mankind to make the desert a livable place and prevent the desert from expanding further. For a long time, measures to prevent and control sandstorms have be...
