Liupanshui is located in the western part of Guizhou Province, on the slopes of the first and second terraces of the Yunnan-Guizhou Plateau, forming a plateau of mountains and valleys. The exposed rocks are mainly sedimentary rocks, of which carbonate rocks are the main ones. In the carbonate rock area, the soil formation is relatively slow, the organic matter content is low, the viscosity is large, the soil is poor, and many fertile soils, such as corn planting, cannot be harvested normally, but are more suitable for bitter growth. The whole city belongs to the north subtropical monsoon humid climate zone. It is affected by low latitude and high altitude, and it is warm in winter and cool in summer, and the climate is pleasant. The annual average temperature is 19.7 °C, the average temperature in January is 3 to 6.3 °C, and the average temperature in July is 19.8 to 22 °C. The annual precipitation is 1200 to 1500 mm. The frost-free period is 200 to 300 days. The terrain is undulating, and the climate difference is obvious in some areas. The rain and heat are basically the same season, which is suitable for the growth of bitterness. The natural conditions of Liupanshui have cultivated the excellent quality of Liupanshui Bitter Rice.
