1. Sterilization within the shed must be thorough: when the vegetables are changed, the dead leaves in the shed must be cleaned up and the disinfection in the shed must be done. After the vegetable is pulled out, 1000 grams of sulphur powder per acre is mixed with sawdust. After mixing, the seeds are placed in various points in the shed. The used agricultural implements, poles, etc. are also put into the shed, and the closed shed is lit after dark fire. Fumigation for 12 hours. After disinfection, planting vegetables is better. 2. The soil should be deep-turned: Many farmers have failed to fully plow their sheds due to a hasty rush, but have just ploughed the vegetable planters. This is incorrect. It's best to deep-flip it by hand or use a rotary cultivator to fully plow the shed. 3. Basal fertilizers must be fully cooked: If these chicken wastes that are not adequately cooked are used, it is very easy to cause harmful gases such as ammonia to accumulate in the sheds, thus causing the vegetables to be smoked.
