At present, some of the earlier wintering quail vegetables have begun to pull out gardens, and winter and spring vegetables are facing planting. Since it was in the winter and the time was rushed, the farmers often paid insufficient attention to some matters, resulting in poor growth after planting. Therefore, the following winter vegetables should be paid attention to in the following three aspects:
First, the disinfection of the shed to thoroughly vegetables After the garden, the vegetable farmers to catch the gargle, so that the winter and spring vegetables in the market as soon as possible, most of the rushed planting in the garden after turning the ground, while ignoring the disinfection of greenhouses, and thus the occurrence of spring vegetable diseases Planted hidden dangers. Therefore, when the vegetables are changed in the winter, the dead leaves in the shed must be cleaned and the disinfection in the shed must be done.
Second, basal fertilizer should be fully cooked in winter, low temperatures, chicken manure accumulated outside the shed is often incomplete fermentation. The winter greenhouses are relatively closed. If these chicken manures are not adequately cooked, it is easy for ammonia to accumulate in the shed and not to go out and smoke vegetables. Therefore, when the vegetables are used for basal fertilization, they must pay attention to see if the chicken manure has fully decomposed. The appearance of brownish odor is not fully cooked chicken manure, should be strictly prohibited. Mixing 1 kg of fertility and 2 cubic meters of chicken manure will fully decompose the chicken manure and increase the effect of decomposition. Some compound fertilizers with too high nitrogen content are not easy to use as base fertilizers in the winter, so as to prevent volatile ammonia from harming vegetables.
Third, before the colonization of vegetables to increase the ground temperature to lower temperature in winter, is not conducive to vegetable seedlings rooted, excessive humidity at low temperatures can also occur roots. Therefore, it is necessary to close the vents of greenhouses 2 days before the planting of vegetables to increase the temperature of the soil so that the vegetables will be rooted as soon as possible after planting, and the seedlings will emerge as early as possible.
