利用氨基酸水解液制备螯合态肥料技术研究

Study on the Technology of Hydrolyzed Animal Proteins(HAP)-based Chelate Fertilizer

利用氨基酸水解液(Hydrolyzed Animal Proteins;HAP)对Fe、Zn、Mn、Cu等微量元素进行了螯合试验。试验结果表明,微量金属元素与氨基酸螯合率达97%以上,螯合物在180 d的时间内基本保持其稳定性。螯合物的一些主要技术指标达到了国家农业部所颁布的氨基酸叶面肥标准。

The chelating experiment to Fe, Zn, Mn, Cu and so on trace element has carried out using hydrolyzed animal proteins （HAP）. The results showed that the chelated rate of the trace metal element and the amino acid reached above 97% , and stability of the amino acid chelates can keep in 6 months. The main technical indicators of the products have reached state-specified standards in the amino acid foliar fertilizer.
