Abstract：The correlation between the threshold temperature of 0 ℃,3 ℃,5 ℃ and 7 ℃ and the initial flowering period of pear was analyzed,and the prediction of pear blossom period was carried out.The daily average temperature data of Guanxian national meteorological observation station from 1961 to 2021 and the observation data of pear phenology from 2012 to 2021 were analyzed by correlation analysis and regression analysis.The results show that the correlation between the limiting temperature of 5 ℃ and the pear blossom period is the best,and the calculation results of the pear blossom period prediction model can provide reference to the local service.
