Abstract:

By using the basic meteorological data of 2001 to 2019 from Yingjisha national meteorological observing station and the phenological observation data and freezing injury data, the freezing rate of flower bud and yield of Amygdalus communis were analyzed. Combined with mathematical statistics, the meteorological factors causing frozen flower bud during overwintering period of Amygdalus communis in Yingjisha were studied. The results showed that the lowest air temperature in winter and its lasting days, the lowest land surface temperature and frozen earth depth caused the freezing of Amygdalus communis buds, but there was no obvious impact of the maximum snow depth of winter and its lasting days and winter precipitation. When the lowest temperature was -23℃ to -18℃, its lasting days and the lowest land surface temperature were the main factors causing frozen flower buds.

Key words: Yingjisha, Amygdalus communis, overwintering, freezing injury, meteorological factor
