Nano desertification control material and preparation method thereof

Abstract

The invention relates to the field of environmental protection, and in particular relates to a nano desertification control material and a preparation method thereof. The nano desertification control material comprises the following components in parts by weight: 1 to 8 parts of phyllosilicate, 4 or more parts of organic matter, 10 to 20 parts of microbial bacteria, and 5 to 7 parts of humic acid. The preparation method comprises the following steps of: in the mixed acid which is generated through the reaction between calcium fluorophosphate ore slurry and sulfuric acid, when the temperature of phyllosilicate slurry is lowered to below 65 DEG C from controlled 78 DEG C, adding the phyllosilicate of which the fineness is 60 meshes, and adding an ammonium salt containing NH4<+>, thus obtaining the phyllosilicate; performing first fermentation on straws to obtain the organic matter and the humic acid; and mixing the phyllosilicate with the organic matter and the humic acid, and adding the microbial bacteria to perform second fermentation. Through the nano desertification control material and the preparation method thereof, water and fertilizers can be better stored and fixed.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a nanometer desert control material and a preparation method thereof. Background technique [0002] Desert governance has become an issue that countries around the world pay more and more attention to in the field of environmental protection, and the governance models of countries vary according to their national conditions. For example, the basic mode of plant desertification control in the Soviet Union is to build pine trees with medium-growing shrubs such as willows in grasslands in grasslands; in semi-desert areas, plant grasses (giant wild wheat, etc.) Planting xerophytic and strong xerophytic shrubs such as Haloxylon Haloxylon and Shaguaizao. In the United States, sand control is mainly concentrated in the sand dunes around the Great Lakes and the coastal dunes of the East and West Oceans. First, coastal grasses are planted to fix the drifting sand, then legumes or ...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing methods of desert control, the stability of sand and nutrients cannot be effectively guaranteed, and a large amount of dust will still be blown up in severe weather such as strong winds.

It is impossible to fundamentally solve the problems of desert, sandy soil water storage, fertilizer storage, sand fixation, water fixation, and fertilizer fixation. All these methods can only treat the symptoms but not the root cause
