Prediction method and system for winter wheat scab

The invention relates to the technical field of winter wheat disease monitoring, in particular to a winter wheat scab prediction method and system, and the method comprises the following steps: S1, collecting scab areas BM of N groups of winter wheat and particle deformation degrees BC of N groups of winter wheat; s2, treating the collected disease spot areas BM of the N groups of winter wheat to generate disease spot expansion speeds BS, and treating the disease spot areas BM of the N groups of winter wheat and the disease spot expansion speeds BS of the N groups of winter wheat to generate the average number of the disease spot areas BM of the winter wheat and the average number of the disease spot expansion speeds BS of the winter wheat. According to the method, the scab area, the particle deformation degree and the scab expansion speed data are directly taken into the influence on the wheat scab, and the influence degree is specifically quantified, so that the prediction precision of the winter wheat scab
