摘　　要：重点研究了 2种络合剂用量对叶面肥料中中、微量营养元素浓度的影响。结果表明 ,通过加入合理的络合剂 ,能明显提高叶面肥料中的中微量元素的浓度 ,同时提出了如何根据理论研究成果设计以氮磷钾为主体加入中、微量营养元素的叶面肥料配方的方法。The focus of the study is on the effect of the dosage of two complexants on the concentration of secondary and micro-nutrients in foliar fertilizers. The results show that the addition of a complexant at a rational dosage will markedly increase the concentration of secondary and trace elements in foliar fertilizers. A method is also proposed to formulate foliar fertilizers based on NPK with the addition of secondary and micro-nutrients in line with the results of the theoretical study.
