Yellow tungsten oxide powder may be used to prepare a heat insulation agricultural film with good heat absorption effect. The new agricultural film can be a land cover film for agricultural or horticultural use, which can warm the soil by absorbing infrared light due to the infrared light absorbing layer containing the infrared absorbing particles – yellow tungsten oxide. But, it does not make the temperature in the greenhouse/shed rise.
Moreover, since the yellow tungsten oxide nanoparticles also have a good ultraviolet blocking effect, the agricultural film also has an excellent heat insulating effect. This shows that such film can play a certain bactericidal effect. And the plants in the greenhouse will grow well without excessive exposure to ultraviolet light. Therefore, this agricultural film is especially suitable for greenhouses in the Yangtze River Basin. Certainly, in the Yangtze River Basin, it is not enough to rely on a single layer of agricultural film for winter in the greenhouse. It must be supplemented with other measures. For example, add heat insulation materials such as grass hoes outside the greenhouse, or put a simple shed in the shed to make a double shed.
