利用钾长石生产长效硅钾肥及产业化前景分析

Production of the Long-term Effectiveness Si-K Fertilizer by Using Potash Feldspar and Its Prospect

该硅钾肥是一种枸溶性的缓效肥料 ,在催化剂和配料的存在下 ,通过加热使钾长石的矿物结构由晶体有序转变成硅钾肥中非晶体无序化。长效硅钾肥的肥效高 ,经济效益好 ,市场潜力大 。

The Si-K fertilizer is dissolved only in citric acid. With potash feldspar being heated under the action of the activator and some ingredient, the change of the ordered crystal structure in the mineral into the non-crystal and out-of-order structure in the Si-K fertilizer takes place. The silicon-potash fertilizer with long-term fertilizer contributes to well-fertilized effectiveness, more profits, and large market potential and bright prospect.
