Simulation of cucumber downy mildew Spread and sedimentation based on HYSPLIT

Cucumber downy mildew is a typical fungal airborne disease in which pathogenic spores are transmitted remotely by air currents, resulting regional endemics. It of great significance to study and analyze the temporal spatial changes spores, especially trajectory sedimentation concentration propagating with airflow air, for prediction cucumbers. Therefore, based on GDAS meteorological data from October November 2017, this uses HYSPLIT-5 model simulate propagation pathogen main cucumber planting areas China, analyzes frequency long-distance long-term series process, explores transmission law provides theoretical basis predicting
