The correct use of agricultural film can not only increase crop yield, but also improve the life of agricultural film, thereby reducing production costs. Therefore, the following points should be paid attention to when using:
First, before covering the agricultural plastic film, ensure that the skeleton is smooth and thorn-free, so as not to damage the agricultural plastic film, and the film is flattened and pressed when covering, and it is best to reinforce it with a grass rope to prevent strong winds. When moving, covering, unmasking, and folding the film, prevent jerking and pulling, so as to avoid the agricultural plastic film being punctured by the scaffolding and being blown by the wind.
Second, the agricultural film is damaged during use and must be repaired immediately. The repair method is hot adhesive method. The hot adhesive method is suitable for polyethylene agricultural plastic films. First wash and dry the broken place, then cut a piece of agricultural plastic film slightly larger than the crack or hole and put it on top of the crack, and then cover a piece of cellophane or aluminum foil in the cigarette box, and use a red-hot iron bar to blanch back and forth on cellophane or aluminum foil a few times, and the two layers of film are bonded.
Third, after use, agricultural plastic film must be flattened and rinsed in time, and hung in a cool place to dry. When storing, sprinkle with a layer of talcum powder and roll it up, without folding and weighing it.
