摘　　要：采用CiteSpace软件,对2001-2024年间覆盖作物-玉米研究的发展趋势进行系统性分析。结果表明,国内外相关研究的发文量均呈上升趋势。美国(331篇)、巴西(67篇)和中国(32篇)发文量居前3位,在国内形成了以曹卫东、赵秋和于爱忠为代表的紧密学术社群,对覆盖作物-玉米研究贡献突出。中国农业科学院及美国农业部农业研究局等机构在该领域具有较高的学术水平。关键词分析表明,玉米田中土壤养分、土壤肥力和产量是覆盖作物研究的持续热点,研究内容从宏观的产量、表型等特征转向微观的生物动态和机理,焦点由传统农业转向现代保护性耕作。综上所述,覆盖作物研究在玉米生产中展现出广阔的研究前景和应用潜力,未来研究应聚焦于覆盖作物的生态效益和农业可持续性,探索其与土壤、微生物间的协同机制,以促进玉米生产的可持续发展。This study used CiteSpace software to conduct a systematic analysis of the development trends in cover crop-maize research from 2001 to 2024.The results show that the number of publications in this field is on the rise both domestically and internationally.The United States(with 331 publications),Brazil(67),and China(32)are the top three in terms of publication volume,with China accounting for 6%of the global research output,highlighting its pivotal role in this field.A close-knit academic community centered on scholars such as Wei-Dong Cao,Qiu Zhao,and Aizhong Yu has made significant contributions to cover crop-maize research in China.Institutions like the Chinese Academy of Agricultural Sciences and the United States Department of Agriculture's Agricultural Research Service have demonstrated high academic standards in this area.Keyword analysis indicates that soil nutrients,soil fertility,and yield in maize fields have been persistent hot topics in cover crop research,with a shift from macroscopic traits like yield and phenotype to microscopic biological dynamics and mechanisms,reflecting a transition from traditional agriculture to modern conservation tillage.In summary,research on cover crops shows broad prospects and potential applications in maize production.Future research should focus on the ecological benefits and agricultural sustainability of cover crops,exploring their synergistic mechanisms with soil and microorganisms to promote sustainable maize production.
