Blue nano tungsten oxide may be used to prepare thermal absorption agricultural plastic film, which is environmentally friendly, non-toxic and transparent with high visible light transmittance and thermal absorption performance. So, such thin film can be applied to agricultural greenhouses. We all know that the solar radiation spectrum has a very important influence on plant growth. The distribution of solar radiation spectrum can be divided into ultraviolet light region, visible light region and infrared light region. The wavelength of the…
