　　Lanzhou watermelons come in a wide variety of types and have a planting history of at least 300 years. They are divided into two main categories: "Shanghe Melon" and "Hansha Melon." The "Shanghe Melon" is mainly grown along the Yellow River in Xigu District, while the "Hansha Melon" is primarily cultivated in the dry sandy fields north of the Yellow River. Lanzhou produces numerous watermelon varieties that evolve rapidly, with currently over 30 different types. The most widely planted is the P2 watermelon, which is known for its high yield, strong resistance, vigorous growth, excellent quality, large size, sweet taste, juicy flesh, fine texture, few seeds, soft pulp, refreshing flavor, and an average sugar content of 10–11%. It matures early, has a short growing cycle, and is available on the market as early as early July. The White Flower Skin watermelon features high yield, short maturation period, thin rind, high sugar content, few seeds, and is currently one of the fastest-growing varieties in Lanzhou with early availability and good economic returns. Among mid-season varieties, Zhongyu No.1 has a green rind and round fruit, averaging 4–5 kilograms in weight.
