The Principle Of Watering In Glass Greenhouses

Glass greenhouse cultivation has brought very good cultivation conditions for many growers, allowing plants to grow in a specific environment. In fact, manual irrigation also has certain advantages, which can be quantitatively controlled and range controlled. Next, let's take a look at the watering principle of the glass greenhouse. The general principle-not to sprinkle too much. In winter and spring, the temperature is low, the plants in the glass greenhouse evaporate slowly, and the water demand is relatively reduced. It requires less watering or spraying at intervals. Choose irrigation or spraying. In the first two days after watering, the humidity in the glass greenhouse is relatively high, and ventilation is required. Water spray time. A friend asked, should I choose a good time? Of course not that serious.

Generally, watering should be around noon in winter. Because the temperature is higher at this time, the effect is smaller. Those who are able to choose well water to irrigate the land as much as possible, the temperature difference should be smaller, and the plant habits should be faster. Sprinkle water flexibly. Here are three and seven words to teach us. Sprinkle on sunny days, less or no water on cloudy days, and avoid sprinkling on snowy days. According to this principle, watering the glass greenhouse will generally not cause problems. This is because the temperature is high on a sunny day, the water transpires quickly, and it is prone to drought; the weather changes from sunny to cloudy, the temperature drops, and the water transpiration decreases, so the water volume should be reduced and the interval should be longer. In a glass greenhouse, the temperature of each part varies greatly, so the amount of water sprayed should be different. In the south of the greenhouse and near the stove and other heat sources, because the temperature is high, the amount of water transpiration will be large, so the amount of water spraying should be larger; the temperature of the east, west, and north sides of the greenhouse is much lower, and the sunshine time is short, so it is necessary to reduce watering as appropriate. the amount.
