【摘要】：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。
[Abstract]:Based on the analysis of the present situation of fertilizer utilization in China, the present situation of fertilizer efficiency of chelating fertilizers in the market is summarized. The results showed that the effects of EDTA chelating fertilizer, humic acid chelating fertilizer and glycol-alcohol chelating fertilizer were significantly higher than those of common inorganic fertilizer, which could not only increase crop yield but also improve quality. Compared with other chelating fertilizers, glycol-alcohol chelate fertilizer has the advantages of easy chelating multi-dentate structure, strong transport ability in plant and good effect of fertilizer. The problems in the synthesis and application of chelate fertilizer were analyzed, and the importance and necessity of developing chelating fertilizer in China were pointed out. It is an effective way to achieve zero increase of fertilizer consumption in China by actively developing carbohydrate chelate fertilizer.
