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 rang 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.本發明係提供一基於保留特定波長之透光材料，其隔熱複合材料及其複合載體，其中，該透光材料係用以保留特定之光波長，使特定區段之光波長得以通過該透光材料；本發明係可應用於植物之培育，使光波長之特定區段為可調節植物生長的光波長範圍，以提高植物行光合作用之效果，使促進植物生長；並可藉由添加隔熱材料，使達致夏天隔熱、冬天保溫之效果，以提供植物適性之生長環境，藉以提升農作物生長效率，進而提高產率，藉可有助於解決人類之糧食問題者。
