中国种业研究热点及趋势展望

Research Hotspot and Trend of China’s Seed Industry

种业作为战略性、核心性产业,关系到中国的粮食安全与经济社会发展大局。基于文献统计法,使用CiteSpace对1992—2020年中国知网(CNKI)数据库国内种业文献进行科学计量可视化分析,绘制出种业领域研究作者、研究机构、关键词的知识图谱。结果显示,种业领域作者和研究机构之间尚未形成稳定、密集的合作网络关系;种业研究的热点主要包括种业创新系统研究、种业发展战略研究、种企发展战略研究与种业管理体系建设研究4个方面。基于此,对未来种业研究前沿进行了展望,“垄三栽培”“有性杂交”“活动积温”等有关优质种质资源培育技术的主题将是未来种业研究的主要方向。

As a strategic and core industry,seed industry is related to food security and economic development in China.Based on the literature statistics method,using CiteSpace to visually analyze documents about the seed industry in China from CNKI database during 1992-2020,and knowledge maps of the authors,research institutions,and keywords were drawn.The results showed there is no stable and intensive cooperative network between authors and research institutions in seed industry,the research hotspots of seed industry mainly include four aspects of seed industry innovation system,seed industry development strategy,seed enterprise development strategy and seed industry management system construction.Based on this,the future research trend of the seed industry was forecasted,the cultivation technology of high-quality germplasm resources will be the main direction of future research,such as ridge-three technique,sexual hybridization,and active accumulated temperature.
