First, the shed should be thoroughly disinfected. Some vegetable farmers have made an early listing of the squat vegetables, rushed to plant in the Qingyuan, and neglected the disinfection work in the greenhouse, laying a hidden danger for the disease of the squat vegetable. When changing vegetables, the dead leaves of the shed must be cleaned up, and the disinfection work in the shed should be done carefully. After the vegetable clearing garden, 1 kg of sulphur yellow powder per acre is added with sawdust, mixed and placed in various points in the shed, and the used agricultural implements are put into the shed, and the dark ignited and then sealed in the closed shed for 12 hours; It can also be used for fumigation with 45% chlorothalonil smog 400-600g per acre . It is necessary to close the shed for 2 days during fumigation and ventilate for 1-2 days before planting . Soil disinfection have shed, 95% of the available agent 450 times hymexazol wet the ground after planting vegetables. In the shed with underground pests, an appropriate amount of pesticide can be applied before the planting to prevent underground pest damage.

 

Second, the soil should be deep. Some vegetable farmers have not rushed to sheds because they havetily changed their rafts, but they have only cultivated vegetables and plowed them. This is not recommended. It is best to turn it over manually, or use a rotary tiller to fully plow the shed. The base fertilizer applied must be fully decomposed.
