Recently, during an interview in the countryside, the author discovered that the sudden high temperatures caused many vegetable farmers to be caught off guard, leaf margins were scorching and plants were wilting, and some common high-temperature diseases began to emerge. Many vegetable farmers have adopted a series of related measures such as large ventilation, shade nets, and some grasshoppers.
In an interview with Gaoling, a greenhouse grower in the village introduced to the author a simple and practical way to cool down—sprinkle cool water to cool down. That is, before the maximum temperature is reached on the day, spray water to cool the plants above the plants. The first is to use the low temperature of the water to reduce the temperature inside the shed; second is to form a water mist in the shed due to the temperature difference, which has a certain refracting effect on strong light.
During the spraying process, it should be noted that fresh water should be sprayed on the top of the plant and in the space below the roof rather than directly onto the plant. Sudden cold stimulation can make the plant unable to adjust in time and cause discomfort; there is also water spray. Do not ventilate the air, otherwise the water will evaporate directly from the tuyere. There is no point in it; then the sprayer should be cleaned to avoid residual drug.
What needs to be reminded is that the most fundamental way to reduce temperature in the greenhouse is to enhance the plant's stress resistance, such as flushing some biological bacterial fertilizers, spraying with a certain amount of plant growth regulators or foliar fertilizers, etc. The resistance of vegetable leaves is reduced by high temperatures.
