Abstract

The total area of Gaoyou City is 1963 square kilometers, of which the land area is 1175 square kilometers and the water surface is 788 square kilometers. The history of aquaculture is long, the area of astragalus breeding is large, and the demand for seedlings is high. At present, all the seedlings of Astragalus membranaceus are wild seed. Carrying out this project in Gaoyou area not only solves the problem of shortage of seedlings of local farmers, but also has a strong help to the implementation and promotion of this project.
