甜菜褐斑病流行规律微机模拟预测模型的探讨

An Exploration on Predicting the Epidemic Trend of Cercospora Leaf Spot of Sugarbeet by Microcomputer

褐斑病是甜菜的主要病害之一,危害性很大。目前对甜菜褐癍病的预测方法陈旧,准确性差,防治上存在较大的盲目性。本文试图阐明利用微机对甜菜褐斑病发生发展起决定作用的自然条件、品种抗性等因素加以归纳整理,得出预测模型,达到准确预测出甜菜褐斑病发生流行规律及发病程度的目的。

The cercospora leaf spot is one of the main diseases infecting sugarbeet. The present method for predicting the epidemic of cercospora leaf spot of sugarbeet is backward with its less accuracy. We try to use the microcomputer to process the factors which influence the occurrence and development of the disease, such as the natural conditions and the resistance of varieties, to obtain a theoretical model by which the epidemical trend and infection degree of the disease can be forecasted accurately. In order to reach the purpose the content relative to the subject was described.
