Led plant lamp professional research plant lighting distribution, and maximize the simulation of natural light, provide accurate spectral range for plant photosynthesis, provide customers with more comprehensive plant growth lighting scheme, for the company’s purpose, to provide consumers and users with high-quality products and services.
Short ultraviolet rays can inhibit the growth of plants, prevent plants from overgrowth, have disinfection and sterilization effects, and reduce plant diseases. Visible light is the raw material for green plants to produce organic matter by photosynthesis. The red orange light is the most absorbed by green plants, followed by blue and purple light, and the yellow green light is the least. Far infrared radiation produces heat effect and supplies heat for crop growth and development. Under infrared radiation, fruit ripening tends to be consistent. Near infrared ray has no use for crops.
Therefore, in our rapid propagation, in the process of hydroponics, red light is used to supplement light to achieve the maximum utilization rate.
1. Compared with the effect of natural light and red light on plant growth, chlorophyll content first decreased and then increased under natural light. However, the chlorophyll content under red light was higher than that under natural light, indicating that red light promoted the formation of chlorophyll, and the result was more obvious with the increase of culture days.
2. The growth of plants under red light is better, which may be due to the higher chlorophyll content, more vigorous photosynthesis and more carbohydrate synthesis, which provides sufficient material and energy for the growth of plants. Let’s look at the chlorophyll and soluble sugar content under natural light and red light.
3. The soluble sugar content of 7 days culture was lower than that of 13 days, and the content of soluble sugar under red light was much lower than that under natural light. After 13 days, the content of soluble sugar under red light was higher than that under natural light, which may be related to the higher chlorophyll content and more vigorous photosynthesis under red light.
4. The activity of NR in stem segments under red light was significantly higher than that under natural light, indicating that red light could promote nitrogen metabolism in stem segments.
In a word, red light can promote rooting, chlorophyll formation, carbohydrate accumulation, absorption and utilization of plant stems. In the process of rapid propagation, the application of red LED plant light has obvious effect on promoting the rapid rooting of various plants and improving the quality of seedlings.
