摘要: 以Web of Science数据库为基础,对1985—2020年发表的以绿肥为研究主题的文献进行可视化分析,为绿肥研究者跟踪研究前沿、把握研究方向提供理论参考。运用文献计量法,结合CiteSpace和VOSviewer可视化分析技术,绘制了绿肥研究学科知识图谱。结果表明,以绿肥为主题的期刊论文发文量整体呈上升趋势;刊载绿肥研究论文最多的国际期刊是《Agronomy journal》,其次是《Plant and soil》《Indian journal of agricultural sciences》;学科共现特征图谱表明,农学学科发文频次最高,影响力最强,而环境科学的交叉最广泛。在研究国家方面,美国、印度、巴西、中国占据主导地位;在研究机构方面,美国农业部农业研究所发文量最多,其次是加拿大农业与食品学会、中国农业科学院;在研究作者方面,中国农业科学院曹卫东研究员是发表绿肥领域论文最多的学者,形成了以其为核心的绿肥研究团队,其次为菲律宾的Ladha团队、巴西的Neto团队。在研究热点方面,绿肥研究集中在绿肥耕作管理、培肥土壤、氮素利用、固碳减排等领域,尤其是中国农业科学院的曹卫东团队在稻田绿肥紫云英培肥土壤、养分利用及固碳减排等方面取得了显著成绩,具有较强的国际影响力。

Abstract: In order to provided theoretical reference for researchers to track domestic and international research frontiers, grasp the research direction, the foreign literature of green manure from 1985 to 2020 were visually analyzed based on Web of Science database.Using the bibliometric method, combined with CiteSpace and VOSviewer visual analysis technology, the knowledge graph of green manure research subjects was drawn. The results showed that the number of papers on the theme of green manure was on the rise, and the international journal with the most research papers on green manure was Agronomy journal, followed by Plant and soil and Indian journal of agricultural sciences. From the network of discipline co-occurrence, agronomy had the highest frequency of publications and the strongest influence, while environmental science had the most extensive coverage. In terms of research countries, the United States had published the most papers, followed by India, Brazil, and China. In terms of research institutions, USDA Agricultural Research Institute has published the most papers, followed by the Agriculture and Agri-Food Canada and the Chinese Academy of Agricultural Sciences. In terms of research authors, Researcher Wei-dong Cao of the Chinese Academy of Agricultural Sciences was the scholar with the most research papers in the field of green manure research and had formed a green manure research team, followed by the Ladha team in the Philippines and the Neto team in Brazil. In terms of research hotspots, green manure research focused on the fields of green manure cultivation management, improving soil fertility, nitrogen utilization, carbon emission. In particular, the team of Wei-dong Cao from the Chinese Academy of Agricultural Sciences had made remarkable achievements in improving soil fertility, nutrient utilization, carbon emission in rice fields with the green manure of Astragalus vulgaris and had a strong international influence.
