Autumn vegetables are the main winter vegetables in Shanghai market varieties. In the autumn cabbage production, the virus disease is the main disease affecting yield and quality. In the big year of virus disease, the output of green vegetables dropped sharply and the loss of edible value for the most part led to a lighter vegetable winter season. Daejeon autumn cabbage virus disease occurrence, development and weather conditions are closely related. In this paper, the relationship between the incidence of autumn vegetable disease and meteorological conditions and its agricultural meteorological indicators and other issues, through the artificial climate chamber made a simulation test,
