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.
