Acidic Sulfate Soil Improvement Materials, Preparation Methods, and Application Methods

Abstract

Disclosed in this disclosure are Acid Sulfate Soil (ASS) improvement materials, and preparation methods and application methods thereof. ASS improvement materials include mixed particle improvement materials and microbial improvement materials. The mixed particle improvement materials include natural mineral materials, organic carbon materials, lignosulfonates, silicates, high molecular polymers, shell powder, fish bone powder, and hydrated lime powder; and the microbial improvement materials include Bacillus megaterium, Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens, Trichoderma harzianum, yeast, and photosynthetic bacteria.During use, the mixed particle improvement material is evenly distributed in the soil, and is well mixed with the soil through rotary tillage; the microbial improvement material is dissolved in water and added to the irrigated land, the water surface depth is 5-10 cm, the land is continuously soaked for 5-7 days, and then agricultural cultivation activities are carried out after the water level naturally decreases. The ASS improvement material in the present disclosure has the effects of deacidification, maintenance and improvement of fertilizer, and increase in production, and has the characteristics of efficiency, green, environmental friendliness, etc.
