The film greenhouse must be windproof

Even if the film in the thin-film greenhouse does not put the floating film, the temperature in the shed after the straw curtain is kept above 18℃. But before removing the grass curtain, farmers should not rush to remove the floating film. In case of sudden wind and rain, you can quickly put down the floating film to prevent the grass curtain from being blown over or wet.

Be sure to set a breathable cover to press the film according to the wind direction. If it is westerly wind or westerly wind when laminating the film, you can only press the west side of the floating film fixed on the back slope of the film greenhouse shed, not the east side, so that even a small amount of wind blows into the bottom of the floating film to form airbags. The air inside will also be driven out quickly to make the floating film close to the grass curtain to prevent the wind from blowing on the floating film and blowing on the grass curtain. When the blowing direction is different, use the opposite method of pressing the film. The same is true for film greenhouses. Vegetable farmers can press a layer of film upwards at the bottom of the gable of the greenhouse to block the joint between the film and the gable, which can prevent strong wind from blowing in and out from the bottom of the film. In order to protect the arch from the wind, the vegetable grower should install a windproof film at the bottom of the east and west sides of the arch, and the width of the windproof film should be from the underground on one side of the arch to the upper vent. For example, when the west wind blows, vegetable farmers will cover the windproof film on the west side to prevent wind from entering the shed from the vent on the west side of the arch shed. If the wind power exceeds level 6, the air outlet on the leeward side of the arch shed should be opened for better wind protection.
