How to protect the wind in the greenhouse
Recently, the windy weather in our district has encountered a lot of windy weather, which has brought a big impact on agricultural production in greenhouses. How to prepare for wind prevention and reduce natural disasters in agriculture? Today we will introduce some tips for the prevention of gale in the construction of greenhouses: (1) Strictly seal the door hole: When strong winds come, it is forbidden to invade the air flow. In particular, if the doorway opens in front of the greenhouse, materials for sealing the door must be prepared; (2) Windproof Winding Machine: Under normal conditions, the winder is stopped at the position slightly upward in the middle of the lighting surface. The wind resistance effect is best, and two ends of the rolling machine roll are connected with wire and anchored with gable anchors. (3) The shed film must be tightly pressed: The greenhouse film most likely to be destroyed by the wind is the shed film, which is the key to wind protection. The shed film is pressed into a wave-like structure through the film line, and when the wind comes, the greenhouse film can be guaranteed. It does not fluctuate up or down, and is relatively stable. The pressure on the film is not tight. When the wind comes, the film is flat, but it fluctuates up and down, making it more vulnerable to damage. At the same time, the sides of the film must be tightly pressed to ensure that the air is not filled, and the greenhouse is filled with greenhouse air. The main reason for the damage. When the wind is extremely large, it is imperative that small bamboo poles can be used to tie the steel frame and pressure the shed film to resist wind, but it will cause many small holes on the shed film to affect the heat preservation; (D) fruit protection: the cultivation of large fruit-shaped greenhouses, especially melons and other crops, the fruit is larger and heavier, when the wind swings the steel frame so that the Guagua fall off, use a net pocket to the fruit pocket; (5) Pressing the film line: Ensure that the film is tightly pressed in the greenhouse. It is strictly forbidden to use a string to simply lay down the problem, or the number of film lines is not enough. It is not possible to pull a few steel frames one at a time. It is best to add a small tightener on each lamination line, which is easy to tighten and can be quickly operated; (6) Greenhouse irrigation: When the greenhouse has a gushing air, if the gully is small, it is necessary to first handle the location of the gushing air and pressure the site of the glacier. When the ventilation is large, first open a suitable tuyere at the lower part of the greenhouse, so that the wind can smoothly flow out, avoid damaging the film, and then tighten the air and close the tuyere that opens at the downwind; Lab Nitrile Gloves,Disposable Gloves,510K Disposable Gloves,Astm D6319 Examination Gloves Puyang Linshi Medical Supplies Co., Ltd. , https://www.linshihealths.com
