The low temperature in winter and the watering of vegetables in greenhouses are different from other seasons. It is necessary to look at the sky, see the seedlings, and reasonably water the plants. This is an important measure to ensure the robust growth of vegetables in greenhouses and increase production.

The first is shallow water and should not be too large. At low temperatures, vegetables evaporate slowly in greenhouses and the water requirement decreases accordingly. Therefore, the amount of watering should be small, the interval time should be longer, and flooding should be avoided. Watering or spraying should be suitable to prevent the roots of vegetables from being chilled and humid. . After the first two days of watering, it is easy to cause the humidity in the shed to increase. It is necessary to pay attention to reasonable ventilation to reduce the temperature and prevent the occurrence of diseases. Ventilation is generally preferred at high temperatures at noon.

The second is proper watering time. Watering of vegetables in winter should be arranged before and after noon. It should be better after 10 o'clock in the afternoon and before 3 o'clock in the afternoon. The greenhouse temperature during this period is relatively high, and the side effects after watering are minimal. Avoid watering in the early morning and evening to prevent freezing of vegetables. Watering should use well water as much as possible, because the well water temperature is higher, which can reduce the physiological stimulation of vegetables.

The third is to look at the days of flexible watering. According to the weather conditions, we should master the principle of “a fair amount of water in the sunny days, little or no pouring in cloudy days, and avoid watering in the wind and snow days”. When the weather changes from sunny to cloudy, the amount of water must gradually decrease, and the interval should be appropriately extended. From cloudy to sunny, the amount of water should increase from small to large, and the interval time should be shortened.

Fourth, the amount of watering should be focused on: The temperature of each part of the greenhouse has a large difference, and the amount of watering should also be different. In the southern part of the greenhouse, large amount of soil moisture evaporates, and the amount of watering can be appropriately larger; the temperature on the east and west sides of the greenhouse is lower, the sunshine duration is also shorter, and the amount of watering should be less
