Three vegetables for winter vegetables

Three vegetables for winter vegetables

When the shed is to be sterilized, it is necessary to clean up the dead leaves in the shed and to do a good job of disinfection in the shed.
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. Can also use 45% of the chlorothalonil smoke agent 400 ~ 600 grams per acre fumigation sterilization, fumigation, the need to close the greenhouse for 2 days, 2 days before planting to open vent ventilation. The soil in the shed is also to be sterilized. The ground can be sprayed with 30% Thiophanate 1000 times or 95% Hymex Agent 450 times. Planting vegetables after disinfection is effective.

The soil should be deep-rooted. Many vegetable farmers have not ploughed their sheds in full due to a hasty rush. Instead, they 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.

The basal fertilizer must be fully roasted. If these chicken manures that have not been adequately cooked are used, it is easy to cause harmful gases such as ammonia to accumulate in the shed, thereby causing the vegetables to be smoked. Therefore, when basal fertilizer is used for vegetables, it is necessary to pay attention to see if the chicken manure has fully decomposed, and the appearance is yellowish-brown odor which is not fully decomposed chicken manure, and must be avoided.
