摘　　要：为全面深入了解玉米种植密度和产量相关研究在国内和国际的现状和发展趋势,以中国知网数据库和Web of Science核心合集数据库中2000—2022年收录有关玉米种植密度和产量领域的文献(5150篇)为样本,基于CiteSpace软件进行可视化分析。结果表明,美国居于该领域总研究量榜首,中国紧随其后,远远超过其他国家,近年来中国对该领域的研究论文数已经赶超美国,并且每年保持100篇以上的发文量。Agronomy Journal期刊发文量最多,共计230篇,在学术界影响力最大。中国学者刘鹏发文数量最多,对该领域的研究进展贡献最大,与其他作者合作也较为紧密。研究机构以高校为主,中国北方居多,各区域机构之间的合作仍有待加强。在该领域,鲜食和青贮等专用型玉米、氮水利用效率、可持续农业、机械化管理、土壤性质、产量损失、数学模型、秸秆利用等是近年来研究热点问题。To have a comprehensive and in-depth understanding of the current situation and development trend of researches on maize planting density and yield at home and abroad,5150 pieces of literature on maize planting density and yield collected from the CNKI database and Web of Science Core Collection database from 2000 to 2022 were taken as samples for visual analysis based on CiteSpace software.The results showed that the United States ranked first in the total research volume in this field,followed by China,far beyond other countries.In recent years,China had overtaken the United States in the number of research papers in this field,and kept more than 100 articles published every year.Agronomy Journal had the largest number of publications,with a total of 230 papers,and had the largest influence in academic circles.Chinese scholar Liu Peng published the most papers,made the greatest contribution to the research progress in this field,and cooperated closely with other authors.The research institutions were mainly universities,mostly in northern China,and the cooperation among regional institutions needed to be strengthened.In this field,special corn such as fresh food and silage corn,water and nitrogen utilization efficiency,sustainable agriculture,mechanized management,soil properties,yield loss,mathematical model,straw utilization,and so on are the hot research issues in recent years.
