Watering the vegetables in the greenhouse, it depends on the sky, but also depends on the ground, but also depends on the variety of vegetables. Generally speaking, the following points should be noted:
First, watering should not be too much. When the temperature in the greenhouse is low, the amount of water should be small, and the interval should be long. Avoid flooding with large water, causing vegetable roots.
Second, watering should not be arranged when the temperature is high at noon. Do not water in the morning and evening. The water temperature should be around 20 °C. Use well water when it is cold.
The third is the weather changes and watering. Sprinkle on sunny days, do not pour or do not pour on cloudy days, avoid watering in cold weather. When the weather turns from sunny to cloudy, the amount of water should be gradually reduced, and the interval should be appropriately lengthened. When the weather turns from cloudy to sunny, the amount of watering should be small to large, and the interval should be relatively shortened.
Fourth, the amount of watering in different parts is different. When the temperature difference between various parts in the greenhouse is large, the amount of watering should be different. The entrance and exit of the greenhouse and the center of the greenhouse are relatively strong, the ventilation is smooth, the temperature is high, the water evaporation of the land is large, and the watering amount is large. More should be a little, north of the shed, the shed along the two sides of low temperature, humidity, short sunshine hours, watering should be less or not watered.
Fifth, different watering periods are different in different growth periods. Generally, watering should be controlled during the seedling stage. If the water is moderately poured in the middle and late stages, the vegetables should be less poured during the slow growth stage, and should be poured more during the rapid growth period.
