研究以动物蛋白废弃物(毛发、蹄角、皮革下脚料等)为主要原料,制备复合氨基酸微量元素螯合微肥的生产工艺及工业生产中的质量控制方法。研究表明,按本工艺,蛋白原料水解为氨基酸的转化率高,且氨基酸的种类齐全。由于生产过程中采用了控制氨基酸配体与金属离子摩尔比的中间控制方法,确保了微量元素与氨基酸的螯合效果。 In this study, animal protein waste (hair, hoof angle, leather scraps, etc.) as the main raw material, preparation of composite amino acid trace element chelated fertilizer production process and industrial production quality control methods. Studies have shown that, according to the process, the conversion of protein raw materials to amino acids is high, and the variety of amino acids is complete. As the production process used to control the molar ratio of amino acid ligand and metal ions in the intermediate control method to ensure the trace elements and amino acid chelating effect.
