分子式:
CAS号:

性质:又称螯合微量元素肥料(chelate micro fertilizers),简称螯合微肥。用螯合剂与植物必需的微量元素(硼和钼除外)制成的肥料,如螯合锌、螯合铁、螯合锰、螯合铜等。螯合微量元素肥料比无机微量元素肥料好,在土壤中不易被固定,易溶于水,又不离解,能很好地被植物吸收利用。也可与其他固态或液态肥料混合施用而不发生化学反应,不降低任何肥料的肥效。但由于这种肥料价格昂贵,目前尚未广泛施用。可用的熬合剂有乙二胺四乙酸(EDTA)及其二钠盐、二乙三胺五乙酸(DTPA)、乙二胺二羟基苯乙酸(EDDHA)和羟乙基乙二胺三乙酸(HEDTA)等。腐殖酸中的黄腐酸也可与微量营养元互素螯合制成螯合微肥。由有机物络合微量营养元素而制成的有机微肥,虽然肥效不及螯合微肥,但价格便宜得多。如木质素磺酸锌、尿素铁络合物(三硝酸六尿素合铁)、黄腐酸二胺铁和环烷酸锌乳剂等。
