Abstract: Using Yanggao County, Datong City Meteorological Bureau from 1972 to 2012 4-5 monthly meteorological data and from 2001 to 2012 in apricot and flowering phenology data, using methods of meteorological statistics and disaster survey combined, according to the early warning index, different grades of apricot florescence freezing injury of florescence freezing injury index to analyze the decadal change. The results showed that: the florescence frost days, fruit period of frost days showed a decreasing trend, freezing injury index declined. In recent years, florescence freezing injury manifested in the effects on flowering, flowering probability of severe damage was rare, and young fruit period of severe freezing injury frequency was small, but once the freeze injury, most severe frost. Through this research, aiming at the kernel (meat) apricot production to adapt to climate change, provide scientific basis for quality and yield, apricot disaster prevention and mitigation, draw on the advantages and avoid disadvantages to provide reference.
