As the saying goes, 'all living things depend on the sun for their growth' there is no life without sunshine. Normal growth and development of crop, flowering results are through photosynthesis, light formation reaction, photoperiod regulation. So to promote plant growth of fluorescent lamps is based on plant growth and development of spectral wavelength selective absorption and development. After using the product, emission spectrum and the selection of plant absorption spectrum matching, in order to achieve the best effect of crops fill light, and other light sources such as: fluorescent lamp, incandescent lamp, high-pressure sodium lamp is designed for the visual effect of people's eyes lighting light source, lighting for humans. A large number of experiments and tests to prove: the eyes light color sensitive area and light color choice area the distinction that having essence. For example: human's most sensitive to green light, and plants for green basic do not absorb light, so will apply to the human lighting light source, used for crops to fill light, the light efficiency is very low. North all kinds of crops in greenhouse, because winter time is short and light cloudy, rain, snow, fog weather will cause serious lack of light; Southern greenhouse crops in the rainy season, the rainy weather phenomenon also can appear the lack of light, the crops can't normal photosynthesis. Plant growth lamp, can scientifically to fill light of plants, it is suitable for all stages of plant growth, can make the plant leaves hypertrophy, root developed, grew well, enhance the resistance and immunity, promote the plant early maturity, increase production, improve fruit quality. Can also inhibit the growth and breeding of relative virus and worm eggs, reducing the amount of pesticides, reduce the pollution to the environment and crops, in line with the current trend of 'green'.
