新型肥料微量元素螯合肥的研究与应用进展

Research and Application Progress of New-type Fertilizer of Trace Element with Chelate Fertilizer

新型肥料因具有成本低、经济效益高,符合“高效环保、低碳节能”的现代农业发展需求等优点,近年来市场发展迅猛,其中螯合剂越来越多被应用于新型肥料生产。为此,从我国肥料应用现状出发,结合对不同类型微量元素的分类及对比,将螯合剂从来源方面分为合成法螯合剂、天然法螯合剂、生物化学法螯合剂和其他法螯合剂,并对其在肥料中的应用现状进行了综合分析;最终得出了螯合肥料的选择要通过高通量检测技术结合应用环境进行选择,走“有机无机相结合—速效持效相互补—螯合态部分替代”的综合路线,微量元素之间应该“速效型—持效型—螯合态型”相互配合才是微量元素肥料持续发展的最佳选择等结论。

In recent years,the market of new-type fertilizer has developed rapidly because of its low cost,high economic benefit and meeting the needs of modern agricultural development of'high efficiency,environmental protection,low carbon and energy saving',among which chelating agent is more and more used in the production of new-type fertilizer.Based on the present situation of fertilizer application in China,combining with the classification and comparison of different types of trace elements,chelating agents were divided into synthetic chelating agents,natural chelating agents,biochemical chelating agents and other chelating agents from the source aspect,and their application status in fertilizer was comprehensively analyzed.Finally,it was concluded that the selection of chelate fertilizer should be carried out through high-throughput detection technology combined with application environment,and the comprehensive route of'organic-inorganic combination,quick-acting and persistent-acting complement each other,and chelate partial substitution'should be taken,and the best choice for the sustainable development of trace element fertilizer should be cooperative with each other by'quick-acting type,persistent-acting type and chelating type'.
