小麦赤霉病是我国长江中下游麦区的重要病害,我省鄂东南沿江滨湖地区尤为严重,其流行频率高,为害损失大。关于该病预测预报的研究,国内外报道甚多,大多都是建立在对病害流行的主导因素分析的基础之上。有的以气象因子为主,有的以菌量为主,有的则是对气象因子、菌量和其他因素进行综合分析,从而作出预报。湖北省小麦赤霉病长期预报协作组(《中国农业科学》1983,1)曾经提出了病害、气象要素、大气环流三者相结合的长期预报方法,但其既要考虑病害与感病期气象要素的关系,又要考虑前期的典型气候特征和前期的天气过程、
Wheat scab is an important disease in the middle and lower reaches of the Yangtze River in our country. The riverside lakes in the southeastern part of Hubei Province are particularly serious. The epidemic frequency is high and the damage to the crops is large. About the disease prediction and forecasting research, there are many reports at home and abroad, mostly based on the analysis of the dominant factors of disease epidemic. Some meteorological factors, some based on the amount of bacteria, while others are meteorological factors, bacteria and other factors for a comprehensive analysis to make forecasts. The long-term forecasting method for the combination of diseases, meteorological elements and atmospheric circulation has been proposed by the Cooperative Group for Long-term Forecast of Wheat Scab in Hubei Province (“Chinese Agricultural Science” 1983,1). However, Elements of the relationship, but also consider the typical characteristics of the previous climate and pre-weather process,
