Routine maintenance methods of greenhouse film

Greenhouse film is an important part of agricultural inputs. Its rational use and daily maintenance have become an important part of saving input costs. Here we introduce several daily maintenance methods of greenhouse film.

Daily maintenance precautions:

1. Anti-rupture: Materials used to build greenhouses. Mostly iron wire, aluminum wire, etc. are used. These hard and sharp materials can easily puncture the film. Therefore, the material used to build the shelf should have a smooth surface. Shape and smooth the pole tip and bamboo joints, and use soft materials such as hemp rope to tie the pole. Do not use hard materials such as iron wire and aluminum wire.

2. Anti-seaming: The greenhouse film is made up of several narrow-width films. If the seams are too narrow. The bonding area is small, and it will cause seams to fall apart when pulled hard. Therefore, the bonding area should be increased when splicing. Improve bonding strength and avoid seams coming off during use.

3. Windproof: The thin and light greenhouse film is easily blown by strong winds in winter. Therefore, after the film is covered, it should be pressed with a laminating line immediately. Generally, a laminating line is pulled every 1-2 scaffolds. The tightness of the line should be moderate. In areas where strong winds often blow, simple wind barriers can be set up on the windward side to reduce wind damage.

4. Anti-aging. After greenhouse production, the film must be washed, dried, and rolled. Place in a ventilated, dry and dark place. This can delay aging and extend service life. Also, during collection. Special care should be taken to protect the film from exposure to sunlight, smoke and fire.

5. Repair frequently: Agricultural film is damaged during use and must be repaired immediately. Nowadays, most manufacturers are equipped with film repair tape.

6. Remove water droplets: During the cultivation of vegetables, due to the large temperature difference between the indoor and outdoor greenhouses. There is often a layer of water droplets attached to the inside of the ordinary film covered, even if it is a non-drip film. Water droplets will also appear after use time, and these water droplets will seriously affect the light transmittance of the shed film. Reduce the temperature inside the greenhouse. Water droplets dripping onto the crops can easily cause diseases. Pay attention to daily exhaust ventilation, which can reduce the moisture content in the greenhouse.
