1. Winter vegetable cultivation requires a larger Greenhouse angle and an arched roof to facilitate light transmission. Greenhouse width and back slope width: For winter production, the greenhouse width should be 6-6.5 meters, and the horizontal distance of the back slope should be 0.8-1 meter to facilitate light transmission and heat retention.
2. Timely pruning and removing side shoots, old, diseased, and dead leaves, is essential. This significantly improves light conditions inside the greenhouse and increases vegetable yield.
3. The quality of the greenhouse film directly affects sunlight transmission and light quality. Therefore, it is crucial to choose a high-quality Sawtooth Greenhouse film with strong light transmission. 0.10-0.12mm long-life, drip-free PVC film is commonly used in production due to its good light transmission and heat retention properties.
4. Regularly cleaning dust and debris from the greenhouse film can increase light transmission by more than 30%. Additionally, snow should be promptly removed from the film after snowfall to increase transparency and light intake.
