Baijiu production is closely related to climate and environment,and superior climate and environment conditions are the important factors for producing high-quality Baijiu.This paper is based on the seven types of meteorological data from Zhenyuan and Renhuai,Guizhou from 1961 to 2022,and compares and analyzes the climate and environment conditions of the two places.The re-sults show that the climate in Zhenyuan and Renhuai is warm,with an average annual temperature of around 16 ℃.The average high-est temperature during the traditional Daqu-making period(June to September)is around 30 ℃,with a high proportion of days ex-ceeding 30 ℃.The air is humid,with an average annual precipitation of around 1000 mm,and the relative humidity remains at 80％throughout the year.The sunshine is abundant,with an average annual sunshine duration of about 1200 h.The wind speed is low,with an average wind speed of 1 m/s to 1.5 m/s.Warm and humid climate,sufficient sunshine and low wind speed are the common climate characteristics of the two places,creating a unique climate environment for Baijiu production.
