为了解设施蔬菜化肥减施技术领域的发展趋势，掌握该技术领域的最新研究热点。本文基于Web of Science(WOS)核心合集数据库，以"设施蔬菜化肥减施技术"为主题进行高级检索，选取2003～2022年发表的810篇文献，利用CiteSpace、VOSviewer、HistCite可视化分析软件，从年发文量、学科分布、发文期刊、发文国家、研究机构、研究学者、主要研究热点及其变化趋势等指标进行计量分析。结果表明:1)从2003～2022年，设施蔬菜化肥减施技术研究领域的文献数量整体呈上升趋势，所涉及的学科以环境科学为主，占文献总数的36。4％，发文量最多的学术期刊有Journal of Cleaner production、Science of the Total Environment等;2)中国、美国、德国在设施蔬菜化肥减施技术研究领域发表论文数量较多，并且国际合作密切，中国科学院、中国农业科学院、中国科学院大学、中国农业大学和南京农业大学是国内论文发表数量较多的研究机构，中国农业大学的陈清、林杉，卡尔斯鲁厄理工学院的Klaus Butterbach-Bahl，西南大学的陈新平是该领域较有影响力的研究学者;3)产量仍是设施蔬菜化肥减施技术研究领域一个重要关注点，未来研究趋势可能将集中于水分利用率及氮素管理等方面。综上所述，各国对设施蔬菜化肥减施技术研究已有大量基础，通过化肥减量增效技术的应用，提升水肥的利用率，提高设施蔬菜产量，推动农业可持续发展是未来的研究焦点。
Bibliometric Study of Papers in the Field of Fertilizer Reduction Technology for Facility Vegetables
[Objective]Understanding the latest research hotspots and development trends in the field of chemical fertilizer reduction technology for facility vegetables was the goal of the present study.[Method]With the help of the Web of Science(WOS)core collection database,an advanced search was carried out with the theme of"Facilized vegetable fertilizer reduction technology",resulting in 810 literatures published from 2003 to 2022 for further analysis.Quantitative analysis was then performed in the aspects such as the number of published papers per year,distribution of disciplines,published periodicals,published countries,research institutions,research scholars,main research hotspots and their changing trends by using the visual analysis softwares of CiteSpace,VOSviewer and HistCite.[Results]The results showed that:1)From 2003 to 2022,the number of literatures in the research field of facility vegetable fertilizer reduction technology showed an overall upward trend,and the main discipline involved was environmental science,accounting for 36.4％of the total number of literatures.The academic journals with the largest number of publications were Journal of Cleaner Production,Science of the Total Environment,etc.2)China,the United States,and Germany were the top countries with the largest number of published papers in the field of research on fertilizer reduction technology for facility vegetables.Moreover,close cooperations were observed among these countries.Chinese Academy of Sciences,China Agricultural University,Chinese Academy of Agricultural Sciences,and Nanjing Agricultural University were among the top research institutions that had published a large number of papers.In detail,CHEN Qing and LIN Shan from China Agricultural University,Klaus Butterbach-Bahl from Karlsruhe Institute of Technology,and CHEN Xinping from Southwest University were the top scholars in this field.3)Yield was still an important direction in the research field of fertilizer reduction technology for facility vegetables,and future research trends should focus on water use efficiency and nitrogen management based on the keywords analysis.[Conclusion]In summary,there are a lot of foundations for the research on fertilizer reduction technology for facility vegetables in various countries.It is the future to improve the utilization rate of water and fertilizer,increase the yield of facility vegetables,and promote the sustainable development of agriculture through the application of fertilizer reduction technology.research focus.
