摘要
根据四川小麦赤霉病的监测资料及平行气象资料分析表明,小麦赤霉病流行的气象条件,主要是小麦抽穗杨花期遭遇暖湿连阴雨天气。提出了四川小麦赤霉病流行的暖湿连阴雨天气标准,并分析了有利于小麦赤霉病流行的暖湿连阴雨天气在季节内和地区的分布特点,及年际间变化规律和大气环流背景,为小麦赤霉病的预测提供依据。
According to the monitoring materials on Sichuan wheat scab and concerned meteorological materials, it was concluded that the meteorological conditions for the epidemic of wheat scab was mainly the continuous warm rainy days at the headingstage. This study presented the imdex of continuous warm rainy days for wheat scab cpidemic and analyzed the regional and seansonal distribution characteristics of continuous warm rainy days for wheat scab epidemic and exhibited the change pattern from year to year and the atmospheric circulation background. This study provided a foundation for the prediction for wheat scab.
