Abstract: The research of fertilization machinery is related to food security and the coordinated development of agricultural production and ecological environment. This paper provides a reference for relevant researchers to systematically understand the development status of the field of fertilization machinery, and provides reference for subsequent research. In order to grasp the current situation and main academic context of the field of fertilization machinery more intuitively, this paper used mathematical statistics and knowledge graph visualization software based on four databases such as Web of Science core papers, China Academic Journal Full-text Database, WIPO Patent Scope and China Patent Full-Text Database, and the knowledge map of fertilization machinery field was drawn. The results show that the number of papers published and patents issued in the field of fertilization machinery has increased year by year. China and the United States have the largest number of papers published and patents issued in the field of fertilization machinery, and the United States Department of Agriculture and the Chinese Academy of Sciences as the center of close cooperation with other institutions. Foreign periodicals in the field of fertilization machinery are mainly agricultural and forestry periodicals, while domestic periodicals are mainly agricultural machinery periodicals. The research directions in the field of fertilization machinery at home and abroad are all based on variable fertilization. Foreign research hotspots and frontiers focus on precision agriculture as a carrier, and the application of sensors, Internet of things, machine learning and other new technologies in the field of fertilization machinery. Domestic research hotspots and frontiers focus on variable fertilization and numerical simulation. In summary, the research in the field of fertilization machinery can be roughly divided into three stages (germination stage, initial stage and development stage), and now it is in the third stage. The future research in the field of fertilization machinery is expected to develop in the direction of unattended mode.
