Trace elements are essential nutrients for plant growth and development， and fertilizers made from them play an important role in improving the yield， quality， and stress resistance of crops， and farmland health. Compared to traditional trace element fertilizers， new trace element carrier fertilizers have the characteristics of good water solubility， strong stability， difficulty in soil fixation， and easy absorption and utilization by plants through the organic combination of efficient carriers and trace elements. Screening or manufacturing efficiency enhancing carrier is the core of developing new trace element fertilizers. This article overviewed efficiency enhancing carrier and their types， as well as the status of studying and developing new trace element carrier fertilizers in recent years. The effects of applying new trace element carrier fertilizers in agricultural production， as well as the main effect mechanisms of various high-efficiency carriers in trace element fertilizers were summarized and analyzed. The status of applying new trace element fertilizers was clarified. The problems existing in the practical application of the new type of trace element fertilizer were pointed out， and targeted suggestions were put forward， and the future direction of efforts was prospected.
