What to pay attention to when watering vegetables
Greenhouse vegetable cultivation is to use greenhouse plastic film to grow vegetables, which is to artificially create a suitable ecological environment, adjust the vegetable production season, adjust market demand, and promote high-quality and high-yield vegetables, which is one of the effective means to increase farmers' income. Reasonable watering is an important measure to ensure the robust growth of greenhouse vegetables and increase yield. The following four countermeasures should be taken for watering vegetables in greenhouses: The first is shallow water: it should not be too large. At low temperatures, the vegetables in the shed evaporate slowly and the water demand is reduced accordingly. Therefore, the watering amount should be small and the interval should be longer. Avoid flooding with large water. It should be watered or sprayed to avoid it. Low temperature and high humidity cause roots of vegetables. In the first two days after watering, the humidity in the shed will easily increase, and reasonable ventilation and cooling should be paid attention to prevent induced diseases. Ventilation is generally appropriate at high noon temperatures. The second is the appropriate watering time: the greenhouse vegetables should be watered according to the seasonal characteristics of the appropriate time to arrange watering is better. The third is flexible watering according to the weather: according to the weather conditions, master the principle of "watering properly on sunny days, less or no watering on cloudy days, and no watering on snowy days". When the weather changes from sunny to cloudy, the amount of water should gradually decrease, and the interval is appropriately lengthened; when it changes from cloudy to sunny, the amount of water changes from small to large, and the interval time changes from long to short. The fourth is to focus on watering: the temperature of different parts of the greenhouse varies widely, and the amount of watering should be different. In the south of the greenhouse and near the heat sources such as stoves and flues, soil moisture and evaporation are large, and the amount of watering can be appropriately large. The temperature on the east and west sides of the greenhouse is low, and the sunshine time is short. The amount of watering should be appropriately small. some.
