The selection of chelating agents is particularly important in the production of chelated medium and trace elements,and the influence of different chelating agents on the physicochemical properties of chelated medium and trace elements is studied;A preparation method for chelated medium and trace elements is introduced,and stability of the resulting chelated products is tested.The results indicate that the prepared chelated trace elements can stably exist in soil leachate and are very stable over a wide temperature range,providing reference for the application of chelated medium and trace elements and having broad application prospects.
