Rainwater will cause certain harm to greenhouses, and it is necessary for us to do a good job in the protection and flood prevention of greenhouses. Vegetable cultivation in greenhouses is a popular way now. There are many types of greenhouses nowadays, large or small. In terms of rain protection, we remind everyone to do this:
First of all, the top air outlet is rainproof, and most greenhouses are composed of two wide shed films and one narrow shed film. Therefore, during the construction of the greenhouse, the position of the air outlet is set at the top of the greenhouse. Prevent rainwater from being poured into the shed due to the irregular discharge on the roof of the shed, causing injury.
Rainproof film is set on the top. Prepare a plastic film with good light transmission. The length is determined by the greenhouse and the width is determined by the size of the air outlet. The plastic film can be hung up to prevent rain. From then on, each side of the canopy film is stringed with an iron wire. The upper end is fixed under the canopy film, the two ends are fixed with iron wires, and the middle can be stabilized by a thin rope. Flow down and into the canal.
