Abstract
A newly developed long-life spectrum conversion film, which converts light from the green light region to the red light region, was investigated for its performance and weatherability. The growth and development of two types of Chinese cabbage and radish grown under the conversion film and non-conversion film (natural light type film) was also investigated. Spectral irradiance of two different thicknesses (60μm and 100μm) of spectrum conversion film was compared to sunlight (non-covering), with the green region decreasing to 0.87 and 0.74 (sunlight=1), respectively, and the red region increasing to 1.06 and 1.11, respectively. The conversion characteristic of the spectrum conversion film was maintained in the nine months after covering the greenhouse. Also, it is considered from the interior weatherability acceleration test that the performances can be maintained for at least five years. The growth of two types of Chinese cabbage increased under the two different thicknesses of conversion films compared with growth under the non-conversion film. The growth of the underground part of the radishes was significantly enhanced under the 100 μm conversion film.
