Winter vegetables change time, rush time, low temperatures, often make the vegetables grow poorly after colonization. In this regard, winter vegetables should pay attention to several aspects.
Sterilization within the shed must be completed after the harvest of vegetables, in order to make the next morning leek market, many farmers easily rushed planting, which laid the hidden dangers for the next vegetable disease. When changing vegetables, it is necessary to clean up the dead leaves in the shed and seriously perform disinfection work in the shed.
It is not true that the soil can't be thrown away and the soil can't be thrown away from the shed. It's best to deep-flip it by hand or use a rotary cultivator to fully plow the shed.
The use of basal fertilizers must be decomposed. The winter temperatures are low, and chicken manure accumulates outside the shed. The fermentation is often incomplete. In winter, greenhouses are kept warm but confined. The use of chicken manure that is not fully decomposed can cause ammonia and other harmful gases to accumulate in the shed. Therefore, when applying basal fertilizer after vegetables are changed, it is necessary to apply adequately decomposed fertilizers. In addition, some compound fertilizers with high nitrogen content are unfavorable.
Before the planting of vegetables, the “warmth†of the land is required, and the ground temperature in winter is low, which is not conducive to the rooting of the vegetable seedlings after planting. Excessive humidity at low temperature can also cause rooting. Therefore, the land must be aired a few days before the vegetable is planted, so that after planting the vegetables, new roots will be established as soon as possible, and the seedlings will emerge early.
