Abstract: In order to make basic weather stations better conduct meteorological service, observation data in phenological period of Yuanling jujube and meteorological data in Chiping County from 1971 to 2014 were compared to explore the advantageous and disadvantageous climatic conditions for Yuanling jujube. The results showed that annual average temperature, frost-free season in Chiping County, and extreme high and low temperature, sunshine hours and precipitation in growth period of Yuanling jujube could satisfy the demand of Yuanling jujube growth. The annual extreme high temperature of Chiping County was usually lower than 42℃ with a shorter duration. Sunshine duration was sufficient (1433.8 h) and conducive to jujube coloring. The average precipitation in growth period was 528.2 mm, which could meet the requirement of high quality and yield jujube. The main meteorological disasters were the uneven distribution and great annual variation of precipitation which could lead to local drought and flood. Besides, late frost and strong wind would also affect the yield and quality of jujube.
