摘要
通过对1989～2000年陇南小麦条锈病越夏调查资料统计分析,明确了越夏菌量与越夏区7～8月降水量密切相关,越夏菌量与秋苗发病及来年流行程度相关显著。组建了以越夏菌量预报来年流行程度的长期预测模型。
Based on analyzing the investigated data of Longnan area during 1989to 2000,it was ascertained that the amount of over -summer pathogens be closely related to the rainfa ll during July to August of the over -summer area,and the amount of over su mmer pathogens be remarkably relate d to the incidence of wheat strip rust on autumn wheat seedlings and the epi demic degree of the disease in the nex t year.Based on the amount of over summer pathogens,a long forecast mo del for the epidemic degree of the dis ease in next year was built up.
