摘要:

[目的]分析我国苜蓿青贮研究领域发展概况。[方法]以中国知网(CNKI)数据库中收录的苜蓿青贮文献为研究对象,利用可视化计量分析软件CiteSpace 5.8.R3绘制苜蓿青贮研究文献知识图谱,对苜蓿青贮研究领域的研究机构、作者进行合作网络分析,对关键词进行共现、聚类及突现分析。[结果]在设定的检索条件下,1994年出现第一篇苜蓿青贮研究论文;1994—2021年苜蓿青贮文献年度发文量呈现上升趋势;《黑龙江畜牧兽医》发文量最多(31篇),《草业学报》总被引频次(763次)和篇均被引频次(31.79次)最高;玉柱发文量最多(34篇),中国农业大学为发文量最多的机构(57篇),以玉柱为中心形成了稳定的科研团队,但跨机构及团队之间合作不够紧密;苜蓿青贮作为关键词出现的频次最高(103次),围绕发酵品质、青贮品质、混合青贮、添加剂、乳酸菌等关键词开展研究。[结论]我国苜蓿青贮研究成果丰富,需加强跨机构、跨地区、跨团队的合作研究;发酵品质和苜蓿青贮微生物群落组成与功能研究、苜蓿青贮微生物制剂的研发等方面仍然是我国苜蓿青贮研究领域的发展趋向。

Abstract:

[Objective] This study aimed to assess the developmental status in the filed of alfalfa silage research in China. [Method] The alfalfa silage associated literature indexed in CNKI database was selected as the research object, and the knowledge map of research literature on alfalfa silage was drawn by using the visual and metrological analysis software CiteSpace 5.8.R3. The cooperative network analysis was performed for the institutions and authors in the filed of alfalfa silage research, and the co-occurrence, clustering and emergence analyses were carried out for the keywords. [Result] Under the set retrieval conditions, the first research paper on alfalfa silage appeared in the year of 1994. The annual number of alfalfa silage publications showed an upward trend from the year of 1994 to 2021. Heilongjiang Animal Husbandry and Veterinary Medicine published the most research papers (31). Acta Prataculturae Sinica had the highest total citation frequency (763 times) and citation frequency per paper (31.79 times). Yuzhu, an author from China Agricultural University published the most papers (34), and China Agricultural University was the organization with the most publications (57). A stable scientific research team has been formed with Yuzhu as the focal point, but collaborations among varied institutions and teams were insufficient. The most frequently used keyword was alfalfa silage (103 times). Researches were carried out focusing on the keywords such as fermentation quality, silage quality, mixed silage, additives and lactic acid bacteria. [Conclusion] The research achievements on alfalfa silage in China are rich, and more collaborations across institutions, regions and teams are necessary. Fermentation quality as well as composition and function of microbial community of alfalfa silage, and research and development of microbial preparations for alfalfa silage are still the developmental trends in the field of alfalfa silage research in China.
