Based on the meteorological data of 8 sets of microclimate monitoring stations in the grape producing area in east foothills region of Helan Mountain and Yinchuan national reference station in 2019, the climate difference between Yinchuan station and the representative station was compared and analyzed, and the vertical changes of meteorological elements at Meiyu Winery were analyzed. The microclimate differences at four wineries in the same climate zone and five sub-regions in different climate zones were analyzed. The results are as follows: (1) Meteorological elements at Meiyu Winery and Yinchuan station in the same region were significantly different. (2) The 10 cm soil temperature fluctuated most and 40 cm soil temperature was most stable on a typical sunny day. The daily average soil temperature on a typical sunny day in autumn and winter increased in the order of 10 cm40 cm in spring and summer. There was no significant difference of relative humidity in each month, growing seasons and the whole year between 50 cm and 150 cm height. (3) In the same climatic zone, the microclimate was greatly affected by topography, altitude and soil type. The higher the gravel content was, the higher the temperature was; the higher the altitude was, the lower the humidity and the greater the wind speed were. precipitation during the growing season was most at Liushi Winery with a lower altitude in front of the mountain, and it was least at Hennessy Winery. (4) The precipitation, air relative humidity and photosynthetic active radiation gradually decreased, and the temperature gradually increased from south to north in five small winery regions in east foothills region of Helan Mountain.
