摘要
试验旨在探究青贮玉米品质领域的研究现状与发展动态。基于中国知网(CNKI)和WOS核心数据库2015—2023年相关文献,采用CiteSpace软件对发文趋势、科研合作网络、关键词共现与聚类、研究前沿及演进路径等进行可视化分析。结果显示,青贮玉米品质相关研究年发文量总体呈上升趋势,以中文文献为主;核心作者群体已初步形成,但跨机构合作相对薄弱;研究热点从早期的“产量”与“发酵品质”逐步拓展至“种植密度”“营养品质”“经济效益”及“播期”等多个维度。关键词突现与时区演化分析表明,“青贮饲料”“品种”“播期”与“消化率”等主题逐渐成为近年来该领域的研究前沿。研究表明,试验结果系统揭示了青贮玉米品质领域的研究态势与发展路径,可为该领域未来的研究方向提供参考。
This experiment aimed to investigate the research status and development trends in the field of silage maize quality.Based on relevant literature from the China National Knowledge Infrastructure(CNKI)and WOS core databases from 2015 to 2023,CiteSpace software was employed to visualize and analyze publication trends,scientific research collaboration networks,keyword co-occurrence and clustering,research frontiers,and evolution pathways.The results showed that the annual number of publications related to silage maize quality generally exhibited an upward trend,with Chinese literature dominating the field.The core group of authors was initially formed,but cross-institutional collaboration remained relatively limited.Research hotspots had expanded from early'yield'and'fermentation quality'to multiple dimensions,including'planting density','nutritional quality','economic benefits',and'sowing date'.Keyword burst and timezone evolution analyses revealed that topics such as'silage feed','variety','sowing date',and'digestibility'had gradually emerged as research frontiers in this field in recent years.The study indicates that the results of this experiment systematically reveal the research trend and development path in the field of silage maize quality,which can provide reference for future research directions in this field.
