Management techniques for shack vegetables in haze weather
One, cucumber, tomato, eggplant, and other types of vegetables. In the winter season, the normal growth of fruit and vegetable vegetables requires higher temperatures, accompanied by cloudy and foggy weather, insufficient lighting, slow temperature increase in the shed, weakened transpiration of the root system, and relatively weakened photosynthesis. If the plants are overloaded and bear fruit If too much, it will not be able to produce the necessary nutrients for the normal expansion of the fruit, and it is very easy to cause falling flowers and falling fruit. At the same time, the humidity in the shed is high and the temperature is low, which can easily cause various diseases. Therefore, we must first "reduce the burden" to reduce the number of fruit on one plant, and pick it up in time for achieving harvesting standards. At the same time, foliar fertilizers should be sprayed to enhance the antifreeze and resistance of the plants. After mixing with Xiaoda 120, potassium dihydrogen phosphate, white sugar, borax and other micro-fertilizers, they are evenly sprayed on the plants to increase the resistance of the plants. To maintain its robust growth. At the same time, minimize the number of watering and top-dressing. If the temperature in the greenhouse is low, the temperature in the greenhouse may be increased or artificial lighting may be used to increase the temperature in the greenhouse and extend the lighting time.
Second, leeks, spinach and other leafy vegetables. Due to the low temperature and high humidity, it is extremely suitable for the occurrence and spread of various fungal diseases, and it spreads and spreads very quickly, such as spinach downy mildew and leek gray mold. The spinach from Beilingtou Village, Dingzhou City, caused severe downy mildew due to low temperatures and low temperatures. For the serious sheds, if they fight blindly and do not achieve a significant effect, they must exterminate the turbulent areas as soon as possible, and then use a fumigation agent to deal with the sheds. According to the needs of the Spring Festival market, the parsley, fennel and rapeseed can be sown quickly. Leafy vegetables to make up for the loss caused by this simmering vegetable. For lightly affected sheds, if the recent foggy weather is not quickly reversed, the spraying method should be minimized when using drugs, and aerosol treatment can be used. To do a good job of exhalation and dehumidification work, we must choose to release moisture at noon, and often use a rag to wipe the fog droplets on the film to reduce the humidity inside the shed. Minimize the number of watering. If you want to irrigate, choose sunny morning to prevent flooding and flood at noon.
Third, nursery vegetables. At present, it is during the busy season of planting seedlings such as cabbage, tomato, and watermelon in the early spring. Most vegetable farmers are used to cultivate seedlings in semi-subterranean nursery beds in Yangshuo or greenhouses. In recent days, continuous low-temperature, dizzy, and foggy weather have adversely affected the normal germination and unearthing of seeds. To ensure the normal growth of seedlings, and for the cultivation of robust seedlings in the coming year, necessary measures must be taken to improve the seedling bed. Temperature, site selection Try to select the location in the middle of the shed, where the temperature is highest in the shed. In addition, it can be covered with a small arch, covering the film, artificial light, warming stove, or add fresh horse dung at the bottom of the nursery bed, to use horse manure fermentation maturity for the seedbed to raise the temperature, where conditions are available An electric hotbed is used to raise seedlings. In summary, the temperature of the nursery bed should be raised to meet the desired temperature for seed germination.
