摘要
A method for preparing an iron silicon sulfur multi-element composite biochar soil heavy metal conditioner, including: adding silicate to agricultural wastes and roasting with air isolated to enable silicate to enter structural pores of biochar; enabling iron-containing slats to gather on kaolinite with a given proportion; enabling sulfate to gather on bentonite with a given proportion; mixing the above three materials evenly according to a given proportion; and adding diatomite and starch to the mixture, and pelleting to prepare the iron silicon sulfur multi-element composite biochar soil heavy metal conditioner. The conditioner can be widely applied in soil heavy metal pollution abatement of rice fields, and it is able to synchronously passivate composite pollutants in acid or alkaline soils to reduce the amount of pollutants absorbed by and accumulated in rice, thereby achieving safe utilization of polluted farmland.
