Promoting the high-quality development of rural towns with agricultural characteristics is of great significance for boosting rural revitalization and modernization, and it will usher in new opportunities in the 14th five-year period. Taking the Northern International Seed and Seedling Town as an example, this paper analyzed its industrial development foundation, explored its development strategies from the construction of the whole industrial chain, linkage of functional systems, integration of industry and city, and other fields, and summarized its implementation path from the aspects of industrial decision making, policy support, system planning, operation mode, and project implementation. Results show that rural town’s agricultural features can build the whole industry chain wisdom circulation, identify key industries, promote the coordinated development of tertiary industry, promote the construction of the depth of fusion system of the cities, and incorporate some new elements into the system, including the ecological+, wisdom+, health+, and culture+ industries. However, during the development process, some problems should be avoided, including uniformed functions and town homogeneity. To promote the sustainable development and modernization of rural towns with agricultural characteristics, this paper suggests to upgrade the core support policy, to build more integrated “1+N” models, to enhance multilateral collaborations, and to create a stage by stage development plan.
