Light Diffusion Greenhouse Film
Diffuse is the phenomenon that light is projected irregularly in all directions after passing through transparent medium. Intuitively, that is, soft light. It is important to emphasize that diffuse light belongs to the light transmittance, so it will not affect the utilization of light energy by plants. Diffuse reflection agricultural film has the following characteristics:
1. Reduce the proportion of direct light transmitted to the shed and increase the proportion of scattered light; The light entering the shed is soft and the light is even, which avoids the burning of crops caused by direct light in high temperature stage.
2. On the one hand, the transmittance of the film is improved and the luminous flux is increased. On the other hand, the diffuse effect will make the fog (scattering light) of the product increase obviously; The temperature of diffuse film is higher in the morning and evening than that of the transparent film - and at noon when the light is strong, the temperature will be lower than that of the transparent film. In some high temperature areas in the south, the temperature in the shed should be reduced at noon, and the crops should be protected from burning and a comfortable artificial working environment should be provided.
3. Diffuse soft light and direct light can reduce the side effects of exposure, increase the light receiving surface by scattering, improve the absorption effect of crops to light, and the light is more uniform and scattered light increases, so that the irradiation area is larger, so that the crops in the shed can get sunlight regardless of whether they are at some dead angle or not.
4. Diffuse agricultural film is mainly used in flower planting, vegetable and fruit seedling raising, etc., so as to avoid direct light burn.
