Dark blue nano tungsten oxide may be applied for producing thermal absorption agricultural plastic film. The obtained agricultural thin film is a type of nano thermal insulating agricultural film with the characteristics of relative high visible light transmittance, infrared shielding rate and appropriate ultraviolet transmittance. In order to obtain agricultural film with excellent heat insulating effect, some experts have specially conducted research on agricultural film with the addition of blue tungsten oxide powder. They found that the nano heat insulation…
