螯合肥料在农业上的应用效果研究

在分析我国肥料利用现状的基础上,综述了当前市场上主要螯合肥料的肥效研究现状。综合研究表明:氨基酸螯合肥、EDTA螯合肥、腐殖酸螯合肥、糖醇螯合肥的肥效明显高于普通无机肥料,不仅可以增加作物产量,而且在改善品质等方面具有显著的优势,其中,糖醇螯合肥具有易螯合的多齿结构,在植物体内输送能力强且肥料效果好,相比其它螯合肥料具有明显的优势。分析了当前螯合肥在合成与施用上存在的问题,并指出目前我国开展螯合肥料研制的重要性和必要性,积极发展糖醇螯合肥料是实现我国化肥用量零增长的有效途径。

The Application Effects of Chelate Fertilizers in Agriculture

By analyzing the domestic situation of fertilizer utilization,this paper reviewed the research progress on the application effects of several major chelate fertilizers in the current market.Amino acids chelate fertilizer,EDTA chelate fertilizer,humic acid chelate fertilizer,and sugar alcohol chelate fertilizer had better application effects than common inorganic fertilizers.They not only increased the crop yields but also improved the crop quality significantly.Compared to the other chelate fertilizers,sugar alcohol chelate fertilizer had considerable advantages of higher transport capacity in plants and better application effect due to its easily chelated multi-tooth structure.This paper analyzed the existing problems in the synthesis and application of chelate fertilizers at present.It also pointed out the significance and necessity of the preparation technology for chelate fertilizers now.To develop sugar alcohol chelate fertilizers was an effective way to realize the "zero growth" in the consumption of chemical fertilizers in China.
