通过对浙江省杭州市、龙游县两地区的有机肥料资源调查和主要有机肥料中养分组成的全面分析,并探讨了有机肥料分解产物与铁、锰、锌氧化物的螯溶作用。试验表明,半腐解有机物料具有较强溶解难溶Fe、Mn、Zn氧化物的能力,从而提高微量元素的有效性。利用新鲜有机肥经酸解矿化与微量元素螯合研制而成的天然有机螯合微肥,能显著改善作物生长而提高作物的产量和品质。 Based on the investigation of organic fertilizers resources in Hangzhou and Longyou counties in Zhejiang Province and the nutrient composition of the main organic fertilizers, the chelation of organic fertilizer decomposition products with iron, manganese and zinc oxides was also discussed. Experiments show that semi-decomposed organic materials have strong ability to dissolve insoluble Fe, Mn, Zn oxides, thereby enhancing the effectiveness of trace elements. The use of natural organic chelated trace fertilizers made of fresh organic fertilizer by acid-mineralization and trace element chelation can significantly improve crop growth and improve crop yield and quality.
