Method for preparing soil conditioner by using ardealite as raw material through high-temperature calcination

The invention relates to the technical field of solid waste resource utilization, in particular to a method for preparing a soil conditioner by using ardealite as a raw material through high-temperature calcination, wherein particles formed by calcined ardealite granulation are utilized, volatile substances in the particles continuously escape outwards to form pores, the air permeability and the permeability of the soil conditioner are enhanced, by supplementing fresh ardealite and blending, the content of free nutrients is increased, the free nutrients can be adsorbed, and the purposes of supplementing nutrients to crops and increasing the yield of the crops are achieved. 本发明涉及固废资源化利用技术领域，尤其是一种利用磷石膏为原料高温煅烧制备土壤改良剂方法，经利用煅烧处理磷石膏造粒而成的颗粒，实现了颗粒内挥发物质不断向外逃逸形成孔隙，增强土壤改良剂的透气性、渗透性，经补充新鲜磷石膏调配，不仅增加了游离养分的含量，而且还能够实现对游离养分的吸附，达到向农作物补充养分，增加农作物产量的目的。
