基于Web of Science数据库对中美苜蓿研究趋势分析

Analysis of the research trend of alfalfa in China and the United States based on the Web of Science database

本文以“Medicago sativa”或“alfalfa”或“lucerne”为题目检索Web of Science核心合集数据库中收录的1998-2021年间紫花苜蓿研究相关文献,并精炼中美两国的发文,以历年发文数量及变化趋势、研究方向、发文机构、发文期刊为主要指标进行对比分析,旨在为我国紫花苜蓿研究提供借鉴,使我国苜蓿产业更好地应用于社会生产。结果表明,美国作为紫花苜蓿研究大国,总发文量远超其他国家,近年主要以农学、乳品动物科学、昆虫学、食品科学等技术性研究为主,注重苜蓿经济性、效益性发展,发文期刊多为乳品类、作物类和动物类专业性期刊;我国作为继美国之后的第二大苜蓿研究国,发文量近年迅速增加,自2016年起年发文量超出美国,主要以植物科学、农学、环境科学等基础性研究为主,侧重于苜蓿抗逆性、品质性研究,发文期刊多为植物类与综合类期刊。未来需根据我国当前苜蓿产业的发展需求,加强紫花苜蓿基础性研究,同时加强研究与生产利用紧密结合,使相关研究更好地服务于我国苜蓿产业的发展。

Alfalfa(Medicago sativa), known as the “queen of the forages”, is one of the most important forage crops that is widely cultivated in the world. Papers pertaining alfalfa published from 1998 to 2021 were retrieved and screened, with the words “Medicago sativa” or “alfalfa” or “lucerne” in the titles, based on the Web of Science database. Further, the papers were refined for those published in China and the United States, and the retrieved papers were analyzed according to the number and trend of published papers, research directions, institutions, and journals to provide reference for the future research of alfalfa in China, and to make China’s alfalfa industry better applied to social production. Our results showed that as the leader of alfalfa research, the United States has far more papers than other countries. These papers mainly focus on agronomy, technical research such as dairy science, entomology and food science, and pay attention to the economic and benefit development of alfalfa. Further, most of the published journals are professional journals of dairy products, crops, and animals. The number of papers on alfalfa in China, the second largest alfalfa research country, has increased rapidly in recent years, and has exceeded that in the United States since 2016. Meanwhile, the papers in China have been based on the basic research of plant science, agronomy, and environmental science, focusing on the stress resistance and quality of alfalfa, and have been published in plant and comprehensive journals. In the future, depending on the current development needs of alfalfa industry in China, researchers should steadily pay attention to the basic research of alfalfa and strengthen technical research of alfalfa, to contribute to better serve the development of alfalfa industry in China.
