In Beijing and Tianjin, the major factors affecting the yield of autumn bean in autumn are the important factors that affect the yield, except for the high temperature in summer which causes flower fall and fall buds. Blight (dead seedlings), blight (dead seedling), rust (leaf disease) are the common diseases of autumn beans in Beijing and Tianjin. For autumn vegetables and stable production, high yield, in addition to the appropriate evening sowing and drug control, the selection of resistant varieties is a cost-effective technical measures.
