The vegetable sheds in the winter sheds have a tight time, and the peasants often pay insufficient attention to some items, resulting in poor growth after the vegetables are planted. What should you watch out for when changing vegetables in winter? First, the disinfection in the shed must be thorough. After the vegetables were parked, the vegetable farmers had to catch up and promote the early listing of the squat vegetables. Most of them rushed to plant and neglected the disinfection work of the greenhouses, laying a hidden danger for the outbreak of vegetable diseases. When changing vegetables, we must clean up the dead leaves from the shed. Add 1 kg of sulfur powder per acre to the sawdust and mix it in the shed. Mix all used farm implements and racks together. Put into the shed, dark fire ignited and closed the fumigation for 12 hours. Can also use 45% of chlorothalonil smoke agent 400-600 grams per acre fumigation sterilization, fumigation, two days to close the greenhouse, open ventilation vents two days before planting. 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. After disinfection, planting vegetables has a good effect. In greenhouses with underground pests, appropriate amounts of pesticides can be applied to the vegetables before they are planted to prevent damage from underground pests. Second, the soil should be deep turned. Many vegetable farmers have failed to fully plow their sheds due to a hasty change. They have only plowed the vegetable cultivation rakes. This is not appropriate. It's best to deep-flip it by hand or use a rotary cultivator to fully plow the shed. Third, basal fertilizer must be fully cooked. In winter, the temperature is low, if chicken manure is used when basal manure is used, chicken manure is often not thoroughly fermented outside the shed. In winter, greenhouses are insulated and relatively airtight. If these inadequately cooked chicken wastes are used, it is very easy to cause harmful gases such as ammonia to accumulate in the sheds and to smoke vegetables. 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. In order to increase the effect of chicken manure, 1000 g fertility can be mixed with 2 m3 chicken manure. Certain compound fertilizers with excessive nitrogen content should not be used as basal fertilizers during this period. Fourth, vegetables must be warmed before planting. The lower ground temperature in winter is not conducive to the rooting of vegetable seedlings after planting. Excessive humidity at low temperature can also cause root collapse. Therefore, two days before the vegetable is planted, it is necessary to seal the vents of the greenhouse and warm the soil so that the vegetables will be rooted as soon as possible after planting, and the seedlings will emerge as early as possible.
