Abstract:

Since 2006, the issue of soil acidification in tea plantations has received widespread attention in the academic community, with a large number of related research results emerging and gradually developing into a new field of knowledge. To analyze the existing literature in the field of soil acidification in tea plantations, identify knowledge clusters and research networks, grasp the research trends and developments as a whole and provide new ideas and references for future research, the article used CiteSpace software to visually analyze the research status, research hotspots and research frontiers of tea garden soil acidification. The results showed that the research on tea garden soil acidification roughly experienced three stages: budding stage (1976 to 1990), slow development stage (1991 to 2005) and rapid growth stage (2006 to 2019); the research group was mainly composed of universities and scientific research institutes in Zhejiang, but the scientific research institutes published a small amount of paper. Among the keywords, “tea tree” had the highest attention, “pH value” was the earliest and long-lasting keyword, and the research of tea garden soil acidification has become a continuous frontier research field. Based on the existing research on tea garden soil acidification, it is necessary to break through the framework of “soil acidity” in the future, expand the research scope, build a research network, innovate research methods and conduct diversified research from a broader perspective.

Key words: tea, soil acidification, CiteSpace, network map analysis, bibliometric analysis
