Abstract:

This study investigated the development of literature from 1972 to 2019, and the current state of knowledge relating to Vicia villosa var. glabresens, using CiteSpace as a bibliometric tool. It was found that the number of publications on V. villosa var. glabresens has grown rapidly over the study period. Key words with a high frequency of occurrence were ‘Green manure’, ‘Production’, ‘Lolium multiflorum Lam.’ and ‘Grass meal’. The journal with the largest number of publications on this crop was Sichuan Animal Husbandry and Veterinary Science, followed by Pratacultural Science and Guizhou Animal Husbandry and Veterinary Science, with article numbers of 10, 8 and 8, respectively. Several authors, including Xinkang Ling, Zaichun Xu, and Chongyi Kuang have published multiple articles on V. villosa, but the majority of authors have only single or occasional publications. At present, the research foci are forage and green manure uses, but in addition for ecological restoration, V. villosa var. glabresens has shown potential for development and utilization.
