Abstract:
Based on the daily average temperature，maximum temperature，minimum temperature，sunshine hours，average relative humidity，precipitation，average wind speed per 2 minutes and maximum wind speed data of concentric national basic weather stations from 1981 to 2020.The new method was used to calculate the daily average temperature，maximum wind speed and maximum wind speed，the changes of climate resources and the climatic factors that led to the reduction of yield of concentric round jujube during the 40-year period from 1981 to 2020 and 2021 by using linear trend coefficient and other statistical methods,in order to provide reference for development of jujube industry.The results showed that,1）in Tongxin county，the climate guarantee rate of average temperature，sunshine and accumulated temperature of 10 ℃ in annual value of meteorological factors for jujube planting exceed 95%，but the climate guarantee rate of annual precipitation was only 2.5%.The climate guarantee rate of the average temperature in the key development period was more than 80% in the budding period and the leafing period，but less than 80% in the flowering period and the fruit growth period.2）During the whole growth period，the average temperature showed an increasing trend，the average wind speed per 2 minutes showed an increasing trend，and the sunshine hours，precipitation and relative humidity showed no obvious change trend，the above five factors had different changing trends in different growth periods.3）The climatic characteristics of the main growing season of concentric jujube were cold-wet，cold-wet，warm-dry and warm-wet in 4 interdecadal variations.4）The main meteorological factors affecting of Chinese jujube in 2021 were low temperature and rainy in germination stage，windy weather from flowering stage to fruit growing stage，hot and rainy weather from flowering stage to fruit growing stage，and rainy weather during ripening stage.
