Flexible insulation for maintenance and insulation facilities
At present, the main insulation facilities used in the shed are insulation quilts. In the process of use, due to the very large tension generated, no matter how thick the insulation quilt, more or less will be elongated, and the insulation When it is damp, the thermal insulation will be moved down due to the greater tension at the lower part. Therefore, the upper and lower ends must be fixed firmly after the insulation is laid. Due to the different heights of the front face of the greenhouse, the strut roller shutter machine also needs to be adjusted many times to prevent the machine head from "arching" the film. When the roller shutter machine is rolled, because the heat preservation quilt on the roller rod is too small to reach the thickness enough to support the machine head, the machine head will form a huge pressure on the heat preservation quilt, straw curtain and shed film at the bottom, which will cause Larger damage. To prevent this from happening, just adjust the distance between the pole and the nose appropriately. Fix the bottom of the pole immediately after adjustment to prevent it from moving. After repairing the insulation facilities, pay attention to flexible insulation according to weather changes. Temperature management in early winter should be based on balanced heat preservation, and avoid drastic temperature changes that affect the normal growth of vegetables. After the temperature drops, the ventilation decreases, and the front face vents should be closed in time. If you do not pay attention at night, cold wind entering the shed will affect the growth and development of the lower fruits, and aggravate the occurrence of physiological problems such as fruit cracking and crumbs. The cover time of the heat preservation quilt should be controlled well, and the night temperature in the shed should not be lower than 12 ℃, and no excessive heat preservation. Short-term low temperature conditions are good for vegetables to adjust their own functions and improve stress resistance. Disclaimer: Some articles on this website are transferred from the Internet.
