络合剂对叶面肥料中营养物质浓度的影响研究

Study of Effect of Complexants on Concentration of Nutrients in Foliar Fertilizers

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.
