Now we can eat off-season fruits and vegetables every season, thanks to the greenhouse. So, the significance of the greenhouse film is relatively large, how to maintain the high temperature of the film at high temperature?
1. Open the bottom hole of the vegetable greenhouse film and the ceiling vent first, and the air convection wind can be dispersed. Try to locate at the bottom of the appetizer film, the height of the inside should be 60-80cm, that is, 10-15cm from bottom to top. Open the front bottom of the ventilation flue, and the wind will pass through the film from the top of the vegetable greenhouse film, which is a better cooling effect.
2. Use water scientifically and increase humidity through the water shed. The watering time is 3-5 days. The watering time should not be too much. The watering day should be small. The watering should be scanned or over-ridged watering, watering, etc. Although there is a lot of groundwater and water, but not much, it can meet the growth and growth of plastic film crops in vegetable greenhouses. Temperature drops in the greenhouse.
Greenhouse film is a tool used by greenhouse farmers. How to store it after use?
1. After using the membrane, it needs to be cleaned up in time. Then wipe the sludge on the film with a rag.
2. Hang the cleaned film in a cool and ventilated place to dry. Due to the moisture on the film, it is easy to age during storage.
3. After drying, roll the film into a simple board with a width of about 20 cm. After rolling, the board is pulled out. When the roller is rolling, farmers can put a small amount of talcum powder to prevent adhesion.
4. Be careful. Build a loft on the roof beam, and then paste a film on it. You don't have to wait until next spring to move it. This method is more convenient and effective.
5. Wash the used agricultural film and dry it, use wooden sticks to make a core roll or bundle, bury it in a pit of 1-2 meters deep, press 30-50 cm of wet soil, and take it out the following year. It is as soft and transparent as the new film.
6. Greenhouse storage. In summer and autumn, the indoor temperature is suitable, and the greenhouse film can be placed in the greenhouse to avoid freezing and cracking of the film.
