Abstract In order to promote the development and popularization of fertilization equipment in China, the current development status of fertilization equipment used in fertigation were been summarized. The technical characteristics, research progress and existing problems of Venturi fertilizer, differential pressure tank, proportional fertilization pump, plunger pump and solid fertilizer dissolving fertilization device were mainly explained and analyzed. Based on the concept of green agriculture development and the development needs of the agricultural internet of things, the future research priorities and development trends of fertilization equipment were proposed. Under the background of the country′s vigorous development of sustainable ecological agriculture, it is urgent to combine the characteristics of regional planting of crops, comprehensively implement strategies, innovate and develop a variety of advanced fertilization equipment and technologies, and establish water and fertilizer management technologies system to effectively improve water and fertilizer utilization. The flow law of water and fertilizer solution in the pipe, optimization design methods, product development and standardization, irrigation and fertilization schedule, and intelligent fertigation system should be investigated to achieve multifunctional, low energy consumption and precision of fertilization equipment.
