Abstract: Taking Derwent series database as the main data source, and using bibliometric method and CiteSpace visualization tool, the invention patents of blockchain agricultural application research in recent ten years were comprehensively analyzed from the aspects of technology development process, technology R & D power distribution, technology hot spots and frontier. The results showed that the research on agricultural application of blockchain had attracted the attention of all countries in the world, especially blockchain technology powerful nations, but it was still in its infancy. China leaded in the R & D intensity of blockchain agricultural application, but lacked innovation, and the R & D subject was mainly enterprises. Business application mode, data processing and data transmission, security management and other related research were the hotspots of blockchain agricultural application research. Database application and software technology related research were the frontier of blockchain agricultural application research. In this condition, China should pay attention to the quality of technological achievements, grasp the technological frontier, pursue the deep integration of technological innovation and agricultural application, and improve the global influence of Chinas blockchain agricultural application.

摘要： 以德温特系列数据库为主要数据来源，利用文献计量学方法和CiteSpace可视化工具从技术发展历程、技术研发力量分布、技术热点与前沿等方面对近十年区块链农业应用研究的发明专利进行全面分析。结果表明：区块链农业应用研究已经引起世界各国，特别是区块链技术强国的高度重视，但目前尚处于起步阶段；中国在区块链农业应用研发强度上较为领先，但创新性不足，研发主体以企业为主；商业应用模式、数据处理与数据传输、安全管理等相关研究是区块链农业应用研究热点，数据库应用和软件技术相关研究是区块链农业应用研究前沿。在这种形式下，我国应重视技术成果质量、把握技术前沿、追求技术创新与农业领域应用深度融合，提高我国区块链农业应用的全球影响力。
