Abstract: Functional organic fertilizer is an important path to promoting the reduction of chemical fertilizer. Due to the lack of systematic literature, there is insufficient understanding of the research progress, hot spots, and trends in this field. This paper adopts CiteSpace 5.8 R1 software, retrieves the literature related to functional organic fertilizer from the CNKI and core data sets of the web of science, and makes statistical and visual analysis from the number of documents, authors, institutions, keywords, and hot spots. The results showed that: ① At present, the research on functional organic fertilizer is in a hot state. The number of papers issued by domestic scholars has exceeded that of foreign scholars in 2021, and the influence of domestic scholars in this field is better than that of foreign scholars. ② Among the domestic scholars and teams, Shen Q. R., Liu Q., Lin, X. G. are important forces in the research of functional organic fertilizer. The institutions are mainly agricultural scientific research institutions and universities, such as Nanjing Agricultural University, Chinese Academy of Sciences, China Agricultural University, Chinese Academy of Agricultural Sciences, etc. On the whole, the amounts of papers issued by foreign scholars are low and scattered, and no obvious research team has been formed. ③ The research keywords at home and abroad mainly focus on the research and development of functional organic fertilizer, and the benefit analysis of the nutrient status, functional diversity change and enzyme activities after the application of organic fertilizer. At the same time, new hot keywords such as functional gene, carbon and diversity analysis have been produced. ④ According to the analysis of timeline mapping, the main clustering types such as organic fertilizer, diversity and adsorption have been formed at home and abroad. Organic fertilizer, biochar, hummus, long-term fertilization observation, bacterial community and diversity are the current hotspots. At the same time, due to the mature application of high-tech means, these hotspots will maintain the research heat for a long time. This paper objectively reveals the research trends, hot spots and trends of functional organic fertilizer, and believes that the research on the functionality, effectiveness and stability of materials in the preparation of functional organic fertilizer should be strengthened at present. At the same time, focus on the environmental benefit analysis after the application of organic fertilizer should include product quality, human health, environmental residue, nutrient slow-release and carbon fixation, in order to better promote green development and ecological revitalization.
