摘　　要：中微量元素是植物生长发育所必需的元素,以无机盐形式直接施入土壤中易被固定,难以被作物吸收利用,而中微量元素螯合肥具有不易被土壤固定、易溶于水、利于作物吸收等诸多优点。概述了生产以化学合成类、有机酸类、动植物提取类、天然小分子类等为螯合剂的中微量元素螯合肥的现状,指出了中微量元素螯合肥在实际应用中存在的问题,并给出了相关的建议。Medium and trace elements are essential elements for plant growth and development. In the form of inorganic salt, due to the easy fixation in the soil, the medium and trace elements are difficult to be absorbed as well as utilized by corps. However, the chelated medium and trace element fertilizers have many advantages, such as being difficult to be fixed in the soil, soluble in water, and easy to be absorbed by crops. A summary is given of the current situation of the production of chelated medium and trace element fertilizers with chemical synthesis, organic acids, animal and plant extracts, natural small molecules as chelating agents. The problems existing in the practical application of chelated medium and trace element fertilizers are pointed out and relevant suggestions are proposed.
