Abstract:

The study aims at providing data reference for the research of nodule nitrogen fixation in legumes. Relevant papers on the effects of nodule nitrogen fixation on legumes in CNKI and Web of Science Core Data Platforms (WOS) from their establishment to early 2020 were searched. Bibliometrics methods and CiteSpace 5.5.R2 software were used to analyze and visualize the publishing time, journals, research institutions, countries, research topics and keywords of the literature. A total of 4886 Chinese and English papers were found, including 3015 Chinese papers and 1871 English papers. The number of published papers increased gradually, and the United States, China and Brazil were the top three countries with most published papers, while French National Academy of Agricultural Sciences was the institution which had the largest number of published papers. The papers were published on 940 journals, mainly journals of microbiology, soil and agriculture. Among them, Soybean Science and PLANT AND SOIL published more papers in this field. The effects of nodule nitrogen fixation on stress resistance of legumes and the gene and genetic diversity of rhizobia are the main directions of current research. At present, the research groups on nitrogen fixation in legumes are relatively stable, and the research still receives attention from scholars at home and abroad. The occurrence and regulation mechanism of nodule nitrogen fixation and the gene and genetic diversity of rhizobia are current research hotspots and possible future research trend.

Key words: nodule nitrogen fixation, rhizobia, legumes, bibliometrics, visual analysis
