Ventilation Method of Anti-insect Netting in High-Temperature Period

For the greenhouse covered with the anti-insect netting, it is not common to have a room temperature of more than 40 ℃. In this case, the ventilation work becomes crucial. How can we do well in the greenhouse during the high-temperature period?

1. Usually, in order to avoid the entry of cold air, the greenhouse will block the wind deflector. In summer, we can remove the wind deflector.

2. It can replace the yarn mesh at the vent with a lower mesh number to expand the vent.

3. An air vent can be added.

4. The exhaust fan can be added appropriately.

5. Remove the straw curtain on the greenhouse, and the vent area above the greenhouse can be opened to a large extent, which can speed up the elimination of high-temperature gases in the greenhouse.

6. If the air outlet is covered with the insect net or sunscreen net, the air outlet can be increased by 10-20 cm during ventilation. If the ambient temperature in the shed is still high when the air outlet is expanded, the front air outlet should be properly pulled up at this time. It must be noted that the opening must also flexibly adjust its height and clear width to control the greenhouse temperature within a scientific and reasonable range.
