The three elements of crop growth are sunlight, temperature, and moisture. The agricultural film is one of the main covering materials of the greenhouse, and the light transmittance, heat preservation, and drip-resistance naturally become its main physical indicators. In order to ensure that the agricultural film can fully function, the following problems should be paid attention to when installing and using the agricultural film. 1. The plastic film must be stored in a shaded, dry place before installation and use. It must not be exposed to the sun and rain. If it is installed in winter, the agricultural film should be placed at room temperature (2-3 degrees Celsius) before installation. 2. The iron and metal wires in the structure of the booth should be well plated and must not use dirty and rusted components. At the same time, avoid using exposed metal wires and creating sharp corners to prevent tearing of the plastic film. 3. During the installation, the agricultural film must be tightened and leveled so as not to affect the use effect. For example, the Greek PEP film has many functions such as light transmission, heat preservation, drip proofing, dust prevention, etc. However, if it is improperly installed, it will not only exert its proper function, but will also seriously affect the service life. 4. Do not put the film against it, otherwise it will not function. If the word “this side of film should face the soil†is marked on the Greek pep film, it will look up in the interior of the shed and it can be read positively. 5. The film should not be installed when the temperature is too high, because the film is thermally expanded at this time, and when the temperature decreases, the film will shrink, causing breakage and tearing. In the event of a rupture, it is advisable to use dedicated tape repairs to avoid affecting the functional effects of the plastic film. 6. Before opening the film roll, check the ground condition of the work place to avoid puncturing or scratching the film. 7. Do not walk on the film. You should not put assembly tools or Other objects on the film to prevent breaking the film. 8. Special attention should be paid to avoid the direct connection of the film and the greenhouse components. If it is unavoidable, a white acrylic-vinyl base should be applied to the connection area. Do not apply mixed organic solvents. 9, to avoid direct contact with crops and irrigation, heating pipes and other equipment and film. 10. Do not burn vegetable residues, crop residues, etc. at room temperature, so as not to damage the film. 11, try to limit the maximum amount of pesticides, herbicides, biological treatment products used to control the concentration of sulfur hydrogen mixture. 12. When using insecticides on plants, prevent spraying on the film. 13. Avoid attachment of insecticides on the membrane in contact with greenhouse components. After the use of pesticides, the greenhouses should be ventilated as soon as possible. 14. In the place where the film is covered, an appropriate amount of soil should be piled on the film so as to prevent the spraying of the disinfectant on the film. 15. Do not use sulfuric acid.
