Plant growth is closely related to photosynthesis. According to the research of botanists, after a plant grows to a certain stage, the luminescence spectrum of light source begins to play a role in its growth and development. Blue violet light and long wave ultraviolet light mainly promote the formation of pigment in plants, and directly affect the absorption of phosphorus and trace metal elements and the formation of vitamin D and cuticle; Blue light is the light energy that promotes photosynthesis; Ultraviolet light (< 350 nm) can destroy plant growth; Green and yellow light inhibited the activity of chloroplasts and decreased photosynthesis; Orange red light is the light energy that greatly enhances plant photosynthesis and is conducive to plant growth. Therefore, other wavelength spectra should be converted into blue light and orange red light as much as possible, especially orange red light, which plays an important role in promoting plant growth, early maturity and yield increase. For the north and northwest regions with long sunshine, dry and long winter in China, The development of agricultural light conversion agricultural film has quite good economic and social benefits. When manufacturing agricultural film, add about 0.3% light conversion powder to make functional light conversion agricultural film. Covering greenhouse crops with the agricultural film, it can absorb the green light, yellow light and ultraviolet light that are destructive to plant growth and development in sunlight, and convert them into orange red light and blue light required for plant photosynthesis, especially orange red light, It can not only improve greenhouse temperature, enhance plant photosynthesis, promote plant growth and development and nutrient absorption, but also improve crop quality, significantly improve plant yield and quality. It has good temperature regulation effect and biological effect. It is a very effective "light fertilizer" without pollution The key technology of light conversion agricultural film is to convert ultraviolet light and yellow green light into orange red light (580 ~ 650nm) light conversion powder which can promote plant photosynthesis
