Consulting serviceThe precautions of film replacement for greenhouse
1. The bamboo rafts in the greenhouse should withstand the heavy pressure of the grasshoppers. When the snow weather is encountered, the bearing capacity will increase greatly, which will cause some of the bamboo rafts to be crushed or crushed. Such bamboo rafts should be maintained or replaced in time. 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, vegetable greenhouse construction of the bottom of the mountain wall wire pad scrap tires or soles, etc., expand the steel wire bearing area, to avoid the steel wire into the gable.
3, the vegetable greenhouse construction in the shed surface and the front turning place pad rag, rubber tube, PVC tube, etc., or put a plastic hose on the laminating rope to avoid direct contact between the laminating rope and the shed film, reduce the lamination The friction between the rope and the shed film slows down the wear rate of the shed film.
4, vegetable greenhouse construction should shorten the time when the old membrane is removed to the new membrane. 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, the construction of inferior membranes and old membranes in vegetable greenhouses is not good for fogging in winter, and it is easy to produce dew when releasing air, which leads to high humidity in the shed, which is not conducive to disease prevention. 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.
