Abstract

The invention provides a high-efficiency saline alkali soil modifier and a preparation method thereof. The modifier comprises chitosan, sodium carbonate, rice bran hemicellulose, bronyl acetate, ammonium citrate, asiaticoside, polyacrylamide, sodium benzoate, sodium succinate, quick lime, manganese dioxide, kieselguhr, opal, potassium humate, nanometer aluminum oxide, lysine and sodium lignin sulfonate. The prepared soil modifier has a comprehensive modification effect on saline alkali soil, the saline content of the surface layer of the soil is remarkably reduced, the contents of organic matter and available nitrogen in the soil are remarkably improved, the texture and structure of the saline alkali soil are improved, the fertility of the soil is improved, the soil is better suitable for agricultural plantation, no secondary pollution can be generated in the modifying process, and application prospects are good.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a high-efficiency saline-alkali soil improver and a preparation method thereof. Background technique [0002] Saline-alkali soil is a widely distributed soil type in the world, and it is also an important and precious soil resource. At present, the area of ​​saline-alkali soil is relatively large. If it is not effectively utilized and protected, the degree of soil salinization and the occurrence of secondary salinization will cause irreversible impacts on the ecological environment. Improvement, development and utilization of saline-alkali land resources can not only improve the ecological environment, but also alleviate the contradiction between population and land due to the increasing population, which is of great significance to sustainable development in all aspects. [0003] Saline-alkali soil improvement is mainly to mature the soil, that is, to impro...
