Now that the temperature is getting higher and higher, some unsuitable temperatures in the film can cause poor plant growth. Therefore, we must master a trick to make the film cool.

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.
In addition, while cooling the greenhouse, the most fundamental thing is to enhance the plant's stress resistance, such as flushing some biological bacterial fertilizers, in conjunction with spraying a certain amount of plant growth regulators or foliar fertilizers, such as Yunda 120, Aidu. Harvest, chitin, etc., can effectively improve the resistance of vegetable leaves and reduce the high temperature hazards.
