Daily maintenance of greenhouse film
The operating procedure of the water replenishment method is to first scrub the damaged area, cut a piece of film that is slightly larger than the damaged area without holes, dipped in water and stick it on the hole, drain the air between the two films, and press it flat. . The paper patch method is generally used when the agricultural film is slightly damaged. Dip a piece of paper in water and stick it on the damaged place while it is wet. Generally, it can be used for about 10 days. The glutinous method is to use white flour and water to make a paste, and then add red enamel equivalent to 1/3 of the weight of dry flour, and it can be used to replenish the film after a little heating. In addition, there is a glue repair method. Wash all around the hole and apply it with a brush dipped in special glue. After 3-5 minutes, take a film of the same texture and stick it on it. The glue can be stuck firmly after it dries. The hot patch method and the glue patch method have good effects on the film patching, but the patch patch method not only leaks air, but also is easy to pull apart, and thinner shed films are not suitable for use.
