In traditional agricultural production, the use of ordinary electric light sources to supplement the illumination and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, to change the light environment to regulate the growth and development of plants in the facility cultivation environment. The led plant grow light adopts different measures to avoid different degrees of problems, such as lack of analysis of specific spectral components, resulting in impure optical quality processing, inconsistent light intensity, close to or even below the plant’s light compensation point. The illumination source has low energy efficiency. A large number of application studies of LEDs in plant facility cultivation environments have shown that LEDs can solve these problems and are particularly suitable for use in artificial light-controlled plant facility cultivation environments.
After application testing, LED grow lights are very suitable for plant growth, flowering, and results. Plants rely on the energy of light for photosynthesis to grow, flower, and produce. However, due to the ever-changing climate change and illumination causes in nature, plants can not fully absorb the photosynthetic nutrients needed during their different growth stages, which brings disadvantages to growth, especially in the seedling stage. In this regard, scientific and rational artificial spectroscopy has created good absorption and reflection conditions for plant growth. The energy values of the blue and red regions are very close to the plant photosynthesis efficiency curve (more significant for green plants) and are the best source of plant growth. Red light promotes rooting, chlorophyll formation, carbohydrate accumulation, and absorption and utilization of chrysanthemum stem segments. The use of red light plant grow light in the rapid propagation process is effective in promoting the rapid rooting of various plants and improving the quality of seedlings. In general, indoor plants and flowers, due to the lack of natural light, will grow worse with time, and by using the LED plant light with the required spectrum (light quality combination) of the plant, it can not only promote its growth but also prolong the flowering period and improve The quality of the flower. Applying this high-efficiency light source system to agricultural production such as greenhouses, greenhouses, etc., on the one hand, can solve the drawbacks of the lack of sunshine, which leads to the decline of the taste of tomatoes, cucumbers, and other greenhouse vegetables. On the other hand, it can also make winter greenhouses and fruits and vegetables in advance. It will be listed before and after the Spring Festival, so as to achieve the purpose of anti-season cultivation.
