SULFATE SOIL IMPROVEMENT MATERIALS, AND METHODS FOR THEIR PRODUCTION AND APPLICATION.

Abstract

The invention relates to an auxiliary acid sulfate soil remediation material (ASS), and a method of its production and application. The ASS consists of a mixed granular auxiliary material and a microbial auxiliary material. The mixed granular auxiliary material consists of natural mineral materials, organic carbon materials, lignosulfonates, silicates, high molecular weight polymers, seashell powder, fish bone powder, and hydrated lime powder; and the microbial auxiliary material consists of Bacillus megaterium, Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens, Trichoderma harzianum, yeast, and photosynthetic bacteria.During application, the granular soil conditioner is evenly dispersed in the soil and thoroughly mixed with the soil through rotary tilling; the microbial soil conditioner is dissolved in water and added to the field with irrigation water, the water surface depth is 5-10 cm, the field is continuously soaked for about 5-7 days, and then agricultural cultivation is carried out after the natural depletion of the water surface. The ASS soil conditioner according to the invention effectively neutralizes acidity, maintains and enhances fertilizers, and increases yield, and also has efficient, green, environmentally friendly characteristics, etc.
