Abstract

The invention discloses a saline-alkali soil improver prepared from ardealite and cane trash, as well as a preparation method and application of the saline-alkali soil improver. The improver is prepared from ardealite, oil cakes, polymeric ferric silicate sulfate, cellulase, mushroom bran, cane trash, diatomaceous earth, nitric acid, EM (Effective Microorganism) bacteria, polysilicate aluminum iron and ethanol. According to the improver, as well as the preparation method and the application of the improver, cellulase is added for enzymolysis after high-pressure sterilization and nitric acid treatment of the cane trash, so that time for decomposing the cane trash by microorganisms can be prolonged to 1 to 2 years, the pH value of the cane trash is reduced to further reduce the pH value of saline-alkali soil after the cane trash is applied to the saline-alkali soil, and moreover, the adsorption capability of the cane trash in sodium colloids can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a saline-alkali land improvement medium prepared by using phosphogypsum and bagasse, and a preparation method and application thereof. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my coun...
