| 摘 要： | 落叶松单宁经降解及亲水化处理，与铁、锰、锌、铜离子反应制备出水溶性螯合物。螯合微肥的应用试验结果：苹果增产１９．８％～２５．４％，银杏叶增产２６．５％。落叶松单宁配体来源于天然成分，与植物有良好的亲和性，而且原料易得，成本低廉，可以成为传统ＥＤＴＡ微肥的的替代品。

| Abstract: | In this study, degradated and hydrophilized larch tannin was used to prepare water soluble chelates with iron, mangnese, zinc and copper ions. The application test of these chelates, as micronurtient, was successful to increase 19.8%.4% apple and 26.5% Ginkgo biloba leaf production. As ligand of the chelate, larch tannin is an abundant natural resource, available in low price, and possesses good compactibility with plants, which can be used as substituent of the traditional EDTA for preparing chelated micronutrients. |
