| 摘 要： | 在四川盆地小麦白粉病初染源研究的基础上,组建了四川盆地小麦白粉病测报模型(MPMSB)。该模型把四川盆地划分为三大区域,针对影响各大区域的菌源地和高空气流走向,确定各大区的关键病情监测点。模型组建从收集菌源地的资料开始,利用天气图和孢子捕捉器监测有利于孢子远程传播的天气系统,根据计算机模拟和贮存的资料进行综合分析作出预报,并送各关键监测点验证。预测结果表明,该模型测报准确,并有可能成为新的测报方法和手段。

| Abstract: | The forecasting model on Wheat Powdery Mildew in Sichuan Basin (MPMSB) was proposed based on the results of initial inoculum of wheat powdery mildew in Sichuan Basin and of other researches. The three regions with different directions high air mass and of inoculum source in Sichuan Basin and the target area of disease incidence survey in each region were designated in this model. Simulation model was founded from the begining of the collection of the data about inoculum source regions A forecast for the disease incidence in Sichuan Basin was made by the analysis of some integrated factors including spore trap in air, simulating calculation of the latent period and other data by microcomputer, weather map in favour of air-borne spore dissemination, and so on. The incidence forecast indicated that this model was of considerable preciseness to target area and may be a new forecasting method in plant disease. |
