无机添加剂对复混肥中有效养分的影响

Effect of Inorganic Additive on Effective Nutrient of Compound Fertilizer

复混肥制作过程中无机添加剂的使用可以导致肥料中有效养分的减少,为了阐明和有效地解决这个问题,选用含有氮、磷、钾3种营养元素的肥料和常用的无机添加剂作为原料,模拟工厂化制作和贮存过程,以分析和探讨无机添加剂对肥料养分有效性的影响。研究结果表明,灰白色膨润土、浅红色膨润土和钙粉对复混肥的有效养分含量均有影响,需根据实际生产需求选取适宜的添加剂。

Inorganic additives could cause effective nutrient of compound fertilizer to decrease in the course of processing and storing. In ordered to solve the problems, the experiment of effective nutrient content changes in the course of processing and storing with different N,P,K fertilizer raw materials and inorganic additives was conducted. The research result indicated that grey bentonite, light red bentonite and calcium carbonate powder would have effect on effective nutrient of compound fertilizer. Inorganic additive should be chose by actual production.
