Temperature was the critical factor to decide whether facility for growing apricot success or not.Near ten year's weather data were analysed and the temperature in different sheds were compared with each other.Three concepts were put forward according to temperature,i.e.suitable scope,less suitable scope and dangerous scope.The lowest and highest temperature in suitable scope among the three period of florescence stage,sensitive period to low temperature,and the stage of first fruit dropping was 2.1-7.7 ℃,13.0-18.8 ℃,3.2-8.1 ℃,13.3-19.0 ℃,4.3-10.6 ℃ and 15.2-24.1 ℃,respectively.In suitable scope,the days of daily temperature being in the scope in the right stage takes account for not less 60% of all days,and the days in dangerous scope,not more than 10%,at the same time,the fatal high temperature and low temperature should be avoided.
