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.
