小麦赤霉病气象环境成因研究进展

Progress in research on meteorological conditions of wheat scab

综述了国内外有关小麦赤霉病发生流行的气象环境成因方面的研究成果及其最新进展,包括小麦赤霉病发生流行的单一、多个气象因子和大尺度气候因子及其对小麦赤霉病发生流行的可能影响。结果表明:温度、雨湿条件、光照、风等气象要素在一定程度上决定了小麦赤霉病的发生流行程度;当温、湿等气象要素,菌源数量与花期在一定程度吻合时,会导致该病的大流行;El Nino和SST异常对赤霉病的发生流行有前兆性指示作用;结合地面气象因子、海温和500HPa高空环流建立的预测模型能够较好地预测赤霉病。还指出了目前研究中存在的不足,对该领域未来研究的发展方向进行了展望。

Achievements and recent progress of research on meteorological and environmental causes of wheat scab occurrence and prevalence at home and abroad were summarized.The causes include single and multi-meteorological factors and large-scale climate factors.The results show that temperature,humility,light,wind and other meteorological factors,in a certain extent,determine the occurrence and prevalence of wheat scab,especially when the temperature,humidity,other meteorological factors and the numbers of bacteria,to certain degree,coincide with the flowering period,it will lead to mass epidemic of wheat scab disease;El Nino,SST anomalies play an precursory roles in the occurrence of scab epidemics;based on combination of the ground meteorological data,SST data and 500HPa high-altitude circulation data,the established prediction model can predict wheat scab better.This paper also points out the shortcomings of the existing research and makes a prediction about the future development of research.
