Abstract

The invention discloses a saline-alkali soil regulator and a processing process and application thereof. The regulator comprises ardealite, oil cake, kieselguhr, polysilicate aluminum ferrite, polyaluminum sulfate, polyferric sulfate, rectorite, cellulase, mushroom residue, bagasse, apatite, acid, EM bacteria, polymeric ferric silicate sulfate and ethanol. The processing process comprises the steps of firstly performing ball milling, ultrasonic treatment, calcination and acidizing treatment for rectorite; adding the ethanol and water into the bagasse, then performing sterilization treatment, mixing a mixture with the acid and adding the cellulase for enzymolysis; performing fermentation treatment for the oil cake, mushroom residue and EM bacteria; mixing the obtained fermented materials with the ardealite powder, the kieselguhr powder, the polysilicate aluminum ferrite, the polyaluminum sulfate, the polyferric sulfate, the polymeric ferric silicate sulfate and the apatite powder, performing granulation, and uniformly mixing the materials obtained through the granulation with the obtained bagasse adsorbent and the rectorite powder to obtain the saline-alkali soil regulator. The saline-alkali soil regulator can reduce the salinity content of saline-alkali soil to a greater extent.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a saline-alkali land regulator and its processing technology and application. 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 country. The formation of alkaline land and alkalized soil i...
