How to promote crop photosynthesis through the excellent light transmittance of PE Film?

Publish Time: 2024-05-08
The excellent light transmittance of PE Film can help promote photosynthesis of crops, thereby improving crop growth and yield. Here are some ways:

Proper selection of film type: Choose a polyethylene film with appropriate light transmission to ensure adequate sunlight transmission, but also consider protecting crops from excessive UV radiation.

Spectral transmittance optimization: Prefer films that provide appropriate spectral transmittance. Different crops may use different spectral ranges in photosynthesis, so the film should be chosen based on the needs of the specific crop.

Reduce light scattering: Some polyethylene films may cause light scattering, reducing light penetration. Choose a film with a low light scattering rate to minimize the loss of light.

Keep the film clean: Keep the surface of the polyethylene film clean to avoid the accumulation of dust, dirt and water droplets to ensure full penetration of light.

Control temperature: Appropriate films can help control the temperature in the greenhouse and provide a suitable growing environment, which is also crucial for promoting photosynthesis of crops.

Reasonable use of sunscreen nets: When excessive sunlight exposure needs to be controlled, you can consider using a sunscreen net with good light transmittance on the surface of the film or inside the greenhouse to reduce the impact of sunlight on crops, but ensure that it does not affect photosynthesis required light intensity.

Through the above methods, the excellent light transmittance of PE Film can be utilized to the greatest extent to promote photosynthesis of crops, thereby improving yield and quality.
