"Dingxi has three treasures: potatoes, yams and potatoes." An old saying has been passed down from mouth to mouth by local people to this day, describing the northwest people's "feelings" for the potato. From self-sufficiency to scale development, from industrial cultivation to industrial upgrading, the potato industry has always been one of the driving forces in the development process of this northwestern city. Dingxi is located in the middle of Gansu Province, at the intersection of the Qinghai-Tibet Plateau and the Loess Plateau. The complex geological and geomorphic features determine the diversity of climate types. As everyone knows, the natural conditions of drought and little rain, but become the advantageous resources suitable for potato breeding and growth.
