Abstract

The invention discloses a coastal saline area conditioner and a preparation method and an application method thereof. The coastal saline area conditioner is prepared from phosphorus, oil cake, monopotassium phosphate, mushroom residue, wormcast, cactus, biogas residue, polymeric ferric sulfate, montmorillonite and nitric acid. The coastal saline area conditioner prepared from the montmorillonite, the polymeric ferric sulfate, polymeric ferric silicate-sulfate and ardealite can neutralize charge on the surface of sodium colloid and destabilize the sodium colloid to promote calcium ions in the ardealite to substitute sodions in colloidal complex, salinity content and pH value in the saline area are lowered greatly, few sodions not taken away with water are absorbed by the montmorillonite, and salinity content in aqueous solution in soil is further lowered accordingly.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a coastal saline-alkali land conditioner and its preparation method and application method. 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 al...
