目前,粉煤灰肥料的产品及生产方法有两类,一类是按一定比例将粉煤灰与氮、磷、钾肥料混合、造粒,干燥制成粉煤灰肥料;另一类是制成复混肥料后,再经过磁场磁化获得粉煤灰磁化肥料。这两类肥料中不含有机养分,添加物中营养成分的速效态、缓效态和迟效态三者没有合理配合,粉煤灰中的残炭没有经过化学处理,不能很好的发挥肥效,磁化肥料的磁化设备投资较大。本技术的目的是提供一种将粉煤灰中的残炭处理成作物生长所需要的养分腐殖酸铵的方法,再通过添加其它的物质,获得粉煤灰多效肥。
At present, there are two types of fly ash fertilizer products and production methods, one is a certain percentage of fly ash and nitrogen, phosphorus and potassium fertilizer mixing, granulation, drying made of fly ash fertilizer; the other is the system Into the compound fertilizer, and then after magnetization magnetic field obtained fly ash magnetized fertilizer. These two types of fertilizer does not contain organic nutrients, nutrients in the additive fast-acting state, slow-acting state and delayed state of the three did not cooperate properly, the carbon residue in the fly ash has not been chemically treated, can not play a good fertilizer , Magnetized fertilizer magnetization equipment investment. The purpose of the technology is to provide a method for treating residual carbon in fly ash into nutrient ammonium humic acid needed for crop growth, and then adding other substances to obtain fly ash multi-effect fertilizer.
