First of all, grasp the watering time. The cucumber in the winter booth should be selected in the sunny morning, because the water temperature is close to the ground temperature at this time, the ground temperature is easy to increase, and there is sufficient time for dehumidification in the afternoon. Watering on a sunny day, not pouring on a cloudy day, the temperature and temperature of the water on a sunny day are high, and the water temperature will not be significantly reduced after watering. However, it cannot be watered for a long time. Therefore, the temperature is high and the ground temperature is low. After the water is poured, the ground temperature is too low and the water absorption in the roots is insufficient, resulting in wilting of stems and leaves.
Second, grasp the amount of watering. In the winter when the cucumbers in the greenhouse are short of water, the amount of watering must not be too large. Water should be poured. Otherwise, the soil will be deprived of oxygen and the roots will suffocate and rot, resulting in yellowing and even death of the leaves.
Again, we must grasp the water temperature. In winter, the water temperature of the river is very low. Directly using river water to pour into the ground will significantly reduce the temperature of the ground, which is unfavorable to the growth of cucumber. It is better to pour groundwater, or build a pool in the shed, pour the water into the pool and then pour it. The water temperature should not be lower than 3°C, and the amount of watering should be small. On the day of watering, it is necessary to restore the ground temperature as soon as possible, and at the same time, to remove moisture as much as possible to prevent downy mildew and powdery mildew caused by excessive humidity.
