Abstract:

To gain a deeper understanding of the research foci, development status, and hotspots in the field of apple tree fertilization, and to provide reference for the future research directions of apple tree fertilization practices, this paper conducted a retrieval of relevant literature from 2000 to 2023 based on the core paper databases of CNKI and Web of Science. Using analysis tools such as VOSviewer and CiteSpace, we performed a visual analysis of the publication volume, publishing institutions, authors of the 761 collected papers, as well as keyword co-occurrence, clustering, and emergence, and constructed a knowledge map in the field of apple tree fertilization. The results indicate that significant progress has been made in apple tree fertilization research in recent years, improving fruit quality, optimizing fertilization strategies, and reducing environmental pollution have become research hotspots. The annual publication volume generally shows an upward trend, with the formation of large-scale research teams and institutions. Keywords such as yield, quality, and soil nutrients remain current and future research hotspots. It is predicted that green manure, sustainable development, soil improvement, and precision fertilization may become hot research directions in the field of apple tree fertilization.

Key words: apple tree fertilization, bibliometrics, visual analysis, CiteSpace, VOSviewer
