摘　　要：流行学田间调查发现树莓灰霉病发生与生育期、温度、降雨量和种植方位有密切关系,另外植株不同部位病情指数存在差异。流行学研究证明多因子Logistic模型可以较好地反映树莓灰霉病流行动态。树莓青果期不易发病,果实采收盛期发病较重并且增长较快,即病害流行逻辑斯蒂期(0.05～0.95)为产果期16～33d,积温达409～877℃,累积降雨量达53～159mm。The occurrence of Botrytis cinerea on raspberry was closely related to temperature,growth stage,rainfall and different orientation based on 2-year epidemics study.Moreover,the parts of plant also influenced disease index.The epidemics fitted the Logistic model.The results showed that Botrytis cinerea disease occured severely on harvest stage and occured slightly on early fruit setting stage.The Logistic period（0.05 to 0.95） was fruit harvesting period from 16d to 33d,with cumulative temperature from 473℃ to 874℃ and cumulative rainfall from 81mm to 175mm.
