Greenhouse film is the main facility for heat preservation and light transmission in winter. In recent years, there have been instances of poor vegetable growth, reduced production, and even death due to problems such as reduced light transmittance and dripping. In the deep winter season, how should the shed film be maintained and managed? Do a good job in shed film dust removal to increase light transmittance Choose a shed film with good dust resistance, which is the basis to ensure that the shed film has less dust. The production materials and processes of greenhouse film are different, and the dust resistance is very different. Currently, the most popular dust removal measure is dust removal cloth strips. The dust-proof belt can be made of long cloth strips, etc., one end is fixed to the roof of the shed, and the other end is fixed under the shed. The length is slightly longer than the span of the shed (generally 0.5 to 0.7 meters longer than the width of the shed film). In this way, the cloth strip will swing with the wind to wipe off the attachments on the shed film, keep the shed film clean, and increase the transmittance of the shed film. In addition, a water spray device can be installed on the top of the shed film to spray water to clean the dust on the shed film when there is too much dust to improve the light transmittance of the shed film. Pay attention to rational use of drugs to slow down the aging of greenhouse film When disinfecting in the shed, ***Do not use sulfur or other acidic drugs for fumigation, and it is strictly forbidden to spray pesticides on the membrane surface. After the film is covered, vegetable farmers must also pay attention to avoiding high temperature and stuffy sheds, otherwise the dripping anti-fogging additives added on the shed film will easily precipitate prematurely and quickly, causing the shed film to turn white and black, which directly affects the light transmittance. In addition, the droplet anti-fog effect will be severely weakened, affecting the normal use of the shed film. Prepare for windbreak and repair damage in time There are frequent strong winds in winter, which damages the shed film, especially the shed film at high temperature. The laminating rope can ensure the flatness and stability of the shed film when the wind blows, and will not fluctuate up and down, so as to prevent the shed film from being broken. It is recommended to choose a nylon rope with a thickness of about 0.6 cm to 0.8 cm. The contact area with the shed film is large and the damage is small. When there are small holes or cracks in the greenhouse film for too long, the vegetable grower can use scotch tape to directly paste it. For larger damage, the vegetable grower must first clean the area around the hole and apply it with a brush dipped in special glue. After 5 minutes to 5 minutes, take a piece of film with the same texture and stick it on it. After the glue dries, you can stick it firmly. In addition, placing a floating film on the thermal insulation quilt can not only increase the thermal insulation and prevent the cover from being wet in rain and snow, but also greatly enhance the wind resistance and prevent the shed film and thermal insulation from being safe.
