1. Damaged bamboo rafts are replaced in time: the bamboo rafts in the greenhouses are subject to the heavy pressure of grasshoppers. When heavy snow weather occurs, the bearing capacity is greatly increased, which may cause some of the bamboo rafts to be crushed or crushed. Such bamboo rafts must be maintained in time or replace. For the bamboo raft that has been crushed, it can be removed or replaced, or attached to the broken bamboo raft. The original broken part is wrapped with a cloth strip to prevent the film from being broken. Bamboo rafts that can only be used in the cracks can be wrapped in cloth.
2. The bottom of the wire on the mountain wall is padded with scrap tires or soles, etc., to expand the area of ​​the steel wire to avoid the steel wire into the gable.
3. Pad rags, rubber hoses, PVC pipes, etc. at the shed and front turning, or put a plastic hose on the laminating rope to avoid direct contact between the laminating rope and the shed film, and reduce the laminating rope and shed. The friction of the membrane slows down the wear rate of the shed film.
4. Be sure to shorten the time it takes for the old film to be removed to the new film. Now the vegetable farmers are helping each other to change the film. They can prepare the bamboo rafts that are ready to be replaced, prepare the new film in front of the shed, remove the old film, and immediately replace the bamboo rafts that need to be replaced. Covering, thus shortening the film change time.
5. Inferior membrane and old membrane are not good in fogging in winter, and dew is easy to produce when the wind is released, which leads to high humidity in the shed, which is not conducive to the prevention and treatment of diseases. It is recommended to replace the membrane on the venting belt once a year and replace it with a membrane with good quality and strong droplets.
6. When the vegetable farmers pull the grass, most of them are shed from the gable, which is easy to break the shed film, and the shed film on the mountain wall is directly exposed to the soil, which is more susceptible to erosion, affecting the insulation and service life of the greenhouse. . It is recommended to cover the old grasshoppers on the two mountain walls immediately after replacing the shed film, and press them with bricks or old cement pillars to prevent the vegetable farmers from stepping on the shed film when they are shed on the one hand, and to prevent the vegetable farmers from rain and snow when they are on the other hand. The upper and lower sheds are slippery for easy walking.
