In traditional agricultural production, ordinary electric light sources are generally used to supplement the light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, and changing the light environment to regulate the growth and development of plants in the facility cultivation environment. Plant panel light adopts different measures to avoid problems of different degrees, such as lack of analysis of specific spectral components, resulting in impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of the plant. The energy efficiency of the illumination light source is low. A large number of application research results of Plant panel light in plant facility cultivation environment show that Plant panel light can solve these problems and is especially suitable for artificial light-controlled plant facility cultivation environment.
 
Plants rely on the energy of light for photosynthesis to grow, flower, and bear fruit. However, due to the ever-changing climatic changes and light changes in nature, plants cannot fully absorb the photosynthetic nutrients they need during different growth periods, which brings disadvantages to growth, especially in the seedling stage. In this regard, the scientific and reasonable Plant panel light artificial spectrum creates good absorption and reflection conditions for plant growth. The energy values ​​of the blue light zone and the red light zone are very close to the efficiency curve of plant photosynthesis (and the efficiency is more significant for green plants), which is the best light source for plant growth.
 
In short, the red light Plant panel light can promote the rooting of chrysanthemum stems, chlorophyll formation, carbohydrate accumulation, absorption and utilization. In the process of rapid propagation, the use of red light Plant panel light to supplement light has obvious effects on promoting the rapid rooting of various plants and improving the quality of seedlings.
