摘　　要：利用贵州蓝莓种植核心区蓝莓开花期近30年逐日气温、降雨、相对湿度等气象资料,通过算术平均、线性演变趋势等统计方法,分析研究利于灰霉病发生的气温、降雨、湿度演变规律。结果表明:贵州蓝莓种植核心区主要种植品种的花期,集中出现在3月上旬到4月下旬;随着全球气候变暖,主栽蓝莓品种花期有显著提前趋势;连阴雨、相对湿度持续≥85%的日数均向有利于灰霉病发生发展的方向演变,特别是最近10年蓝莓花期降雨、湿度条件更有利于重级灰霉病发生。Based on the daily temperature,rainfall,relative humidity and other meteorological data during the flowering period of blueberry in the core blueberry planting area of Guizhou in the past 30 years,the change law of temperature,rainfall and humidity conducive to gray mold disease is analyzed by statistical methods such as arithmetic mean and linear evolution trend.The results show that the flowering period of the main blueberry varieties in the study area is concentrated in early March to late April.With global warming,the flowering time of the main blueberry varieties shows a significant trend of antedating.The days of continuous rain and relative humidity≥85%,which is conducive to the occurrence of gray mold disease,are increasing.In recent 10 years,the rainfall and humidity conditions during the flowering period of blueberry are more conducive to the occurrence of severe gray mold disease.
