In the traditional agricultural production, ordinary electric light sources are used to supplement lighting and apply different covering materials and other agricultural technical measures. For example, monochromatic fluorescent lamps or colored plastic films are used to change the light environment to control the growth and development of plants in the facility cultivation environment. led plant lamp uses different from these measures, thus avoiding the existence of varying degrees of problems, such as the lack of analysis of specific spectral components resulting in impure processing of light quality, light intensity inconsistency, close to or below the plant's light compensation point, Low light energy efficiency. The large number of LED applications in plant cultivation environment research results show that LED can solve these problems, especially suitable for artificial light control plant cultivation environment.
Plants rely on the energy of light for photosynthesis to grow, bloom, and the result. However, due to the ever-changing nature of the ever-changing climate change and light variations, plants can not fully absorb the photosynthetic nutrients they need during different growth periods in different growth periods, which is unfavorable for growth, especially in the seedling raising stage. In this regard, scientific and rational artificial spectrum of plant growth has created a good absorption and reflection conditions. The energy values of the blue and red regions are very close to the efficiency curves of photosynthesis of plants (more so for green plants) and are the best sources of plant growth.
In conclusion, red light can promote rooting, chlorophyll formation, carbohydrate accumulation and absorption and utilization of stem segments of chrysanthemum. In the process of rapid propagation of plant light supplemented with red light for a variety of plants to promote rapid rooting and improve seedling quality significantly.
