In spring, there are more windy days and the greenhouse film is easily exposed or torn. Therefore, strengthening the greenhouse is the key to ensuring the safe production of vegetables. Do you have a good idea in strengthening the greenhouse? Spring Rain: Listen to the weather forecast in time, and take reasonable measures to respond to the predicted wind force is the basis for preventing the danger of strong winds. In general, the north wind below the 5th level does not pose much threat to grasshoppers and shed films, but the 4th westerly wind or east wind can blow the grasshoppers. Therefore, it is necessary to cover the sheds in advance according to the forecasted wind size and wind direction. The material is compacted. With the increase of temperature, even if the greenhouse does not put a floating film, the temperature in the shed can be kept above 18°C. But before there is no retreat, do not rush to remove the floating membrane, and quickly drop the floating membrane when encountering sudden gale and rainy weather, so as to avoid the grasshopper being blown by strong wind or get wet by rain. Flowing Xia: If the wind is blowing westerly or westerly wind, for the floating membrane fixed on the back slope of the shed, only the west side of the floating membrane can be pressed well and the east side is not pressed, so that even a small amount of wind blows into the bottom of the floating membrane. Airbags, the air in the airbags will be quickly expelled, so that the floating film clings to the grasshoppers, so as to prevent the strong wind from blowing up the floating film and blowing the grasshoppers; when the wind is blown against the east wind or east wind, the pressure is reversed. Membrane method. The same applies to the greenhouse film. A film can be pressed up at the bottom of the gable wall to block the joint between the film and the gable to prevent the strong wind from blowing through the bottom of the film to blow the film. Old farmers: If there are tall objects near the arch shed, the number of membrane ropes should be increased, and the entrances and exits of the arches should be sealed tightly to prevent the air flow from entering. Longfei: For the reinforcement of the arch sheds, a windproof membrane can be installed at the bottom of the east and west sides of the arch shed. The width of the windproof membrane must be from the underground side of the arch shed to the uppermost vent. For example, when the west wind is blown, the windproof membrane on the west side will be erected so as to prevent the strong wind from entering the shed from the vent on the west side of the arch and prevent the wind from blowing the film. If the wind exceeds level 6, it is also necessary to open the vent on the leeward side of the arch shelter to ensure that the air in the shed is exhausted. For the east-west shed, attention should be paid to strengthening the wind resistance of the shed film on both sides. First, the import and export should be tightly closed, and the second is to set the film ropes on both sides of the shed film. However, it should be noted that the film on both sides of the booth has a certain angle of inclination, and the use of film ropes is not good. A wide cloth strip of about 5 cm can be used to draw diagonally on the ground anchor at a vertical angle to the film. Tian Daoqinqin: The sheds equipped with roller blinds have certain wind resistance, but their wind resistance is limited. Once the wind is too strong, the strong wind will directly tear the grasshopper's fixed part when it is blown, resulting in losses. It is heavier than a shed without a shutter, so do not rely entirely on the shutter for wind protection. When the wind is greater than 5, to avoid accidents, the floating membrane should be put down for wind protection.
