Abstract: The present invention provides a light transmissive material based on retainment of specific wavelengths, and its insulation composite material and composite carrier thereof, wherein, the light transmissive material is used to retain specific wavelengths of light, so that the wavelength of light of a specific section can pass through the light transmissive material. The invention can be applied to the cultivation of plants, letting the specific section of light wavelengths conform to the range of the light wavelengths, which can regulate plant growth, to enhance the photosynthesis effect of plants, and promote plant growth. Also by adding heat insulation materials, to achieve the effect of summer heat insulation and winter heat preservation, which provides a plant-adapted growth environment, thereby improving crop growth efficiency and increasing the yield, which can help solve the problem of human food.

Abstract: A continually ink-supplying device for an inkjet printer includes a plurality of ink containers positioned on an upper or a vertical side of an inkjet printer and a plurality of guide tubes respectively connecting each said ink container with a ink tube or a ink cartridge of a printer. Each ink container has a tube hole and an ink hole closed with a cap. The guide tube is inserted through the tube hole, having its front end reaching to the inner bottom of the ink container, and having its rear end connected with an ink tube or an ink cartridge of the printer. Then the ink container is made transparent or semi-transparent to be visible to let a user know readily the quantity of the ink stored therein, and the user can refill readily to prevent ink from interrupted in printing.
