中微量元素螯合型肥料研究进展

Research Progress of Chelating Fertilizer with Medium and Trace Elements

螯合型肥料作为一种现代新型肥料,其应用是农业生产上的又一次革命。中微量元素螯合型肥料因其在配肥过程中加入螯合剂,生成中微量元素螯合态养分,具有易溶于水,植物根系吸收利用效果好,不易形成土壤板结,缓释控释,营养全面均衡等特点,实现了对传统肥料的改进,受到了越来越广泛的关注。论述了近年来中微量元素螯合型肥料制备及其在农业应用上的研究现状,并对螯合型肥料未来的发展趋势进行了展望。

Chelate fertilizer is a new type of modern fertilizer,and its application is another revolution in agricultural production.As the addition of chelating agent in the process of fertilizer allocation,chelating nutrient of medium and trace elements is generated,which is an improvement on the traditional fertilizer.Chelated fertilizer has many excellent characteristics,such as easily soluble in water,absorption and utilization effect of plant roots is good,not easy to form soil compaction,slow and controlled release,comprehensive and balanced nutrition and so on.Therefore,chelated fertilizer has attracted more and more attention.The research status of medium and trace element chelating fertilizer in its preparation and agricultural application in recent years was reviewed,and the development trend of chelating fertilizer in the future was prospected.
