Provincial agricultural research institutes are local agricultural research institutions. They are familiar with local agricultural and rural conditions, and have advantages in scientific and technological achievements, technical reserves and the construction of scientific and technological talent support systems. In the process of promoting the implementation of the rural revitalization strategy, all the responsibilities and obligations of the agricultural research institute are to identify the focus of scientific and technological support and talent support in rural revitalization, and break the bottleneck and constraints of rural revitalization. By sorting out the current situation of agricultural science and technology experts serving the grassroots in the problem of talent support for rural revitalization, this paper analyzed the existing problems and put forward countermeasures and recommendations.
