摘要： Greenhouse screen for use as a filter for short-day treatment of plants and made of a film, textile, non-woven material or a combination thereof with high light resitance and good weathering conditions. The greenhouse screen at least partly consists of a material which in one or more layers has high absorption of light in a significant part of the wavelength interval 575-800 nm and with substantially total absorption in the wavelength interval 600-750 nm and which has high transmittance of light in the wavelength interval 400-575 nm.
