Red light and blue violet light are the most effective for photosynthesis of green plants. Chlorophyll in chloroplasts of green plants mainly absorbs red light and blue violet light in sunlight, while carotenoids mainly absorb blue violet light, that is to say, red light and blue violet light are the most effective light response to photosynthesis.
The main spectra of plant growth lamps are concentrated in the blue and red areas. Scientists found that the spectral energy distribution of the lamp is very close to the efficiency curve of plant photosynthesis (especially for green plants), and it is the best light source for plant growth. The lamps that promote photosynthesis of plants use three band lamps with wavelengths of 430nm, 555nm and 630nm. This kind of lamp can promote the metabolism of flowers and accelerate the photosynthesis of flowers.
Modern agricultural plants control and regulate the industrial process of plants through the use of plant growth lights in greenhouses. The advantage of this approach is that it can get rid of the impact of natural climate change on crop growth, so that the whole agricultural production process is always in a controllable state.
