Short ultraviolet rays have an inhibitory effect on the growth of plants, can prevent plants from growing excessively, have disinfection and sterilization effects, and can reduce plant diseases. Visible light is the raw material for green plants to produce organic materials through photosynthesis. The chlorophyll of green plants absorbs the most red-orange light, followed by blue-violet light, and the least absorption of yellow-green light. Far-infrared rays produce heat effect and supply heat for crop growth and development. Under the irradiation of infrared rays, the ripening of fruits tends to be consistent, and near-infrared rays are useless for crops.
Therefore, in our fast propagation, red light is used to fill light in the process of hydroponics to achieve the maximum utilization rate.
1. In the process of stem growth, compare the effects of natural light and red light on plant growth. Under natural light, the chlorophyll content first decreases and then increases. However, the content of chlorophyll under red light is higher than that under natural light, indicating that red light has a significant promotion effect on the formation of chlorophyll, and this result becomes more obvious as the number of cultivation days increases.
2. Plant growth is better under red light, which may be due to the higher chlorophyll content in the plant body, stronger photosynthesis, and more carbohydrate synthesis, thus providing sufficient material and energy for plant growth. Let’s take a look. Chlorophyll and soluble sugar content under natural light and red light.
3. The soluble sugar content of 7 days of cultivation was lower than that of the 13th day, and it decreased more under red light than under natural light. The stems under red light also took root earlier than under natural light. After 13 days, the soluble sugar content under red light was higher than that under natural light, which may be related to the higher chlorophyll content under red light and stronger photosynthesis.
4. The activity of NR in stems under red light is significantly greater than that under natural light. It can be seen that red light can promote nitrogen metabolism in stems.
In short, red light has the effect of promoting plant stem rooting, chlorophyll formation, carbohydrate accumulation, absorption and utilization. In the process of rapid propagation, the use of red LED plant lights to supplement light has obvious effects on promoting the rapid rooting of various plants and improving the quality of seedlings. LED plant lights specialize in the research on the light distribution of plant lighting, and simulate natural light to the greatest extent, provide accurate spectral range for photosynthesis of plants, and provide customers with more comprehensive plant growth lighting solutions. It is the company’s purpose for consumers and users to provide High-quality products and services.
