Since blue is good for plant leaf growth, and red is good for plant flowering and fruiting, the number of red and blue lamp beads in this lamp can be specially made according to the user's plant requirements for light.
There are four forms of light and plant light affecting plants: light quality, photoperiod, light intensity and light quantity. Plant growth and yield (plant size, number of flowers and other characteristics) are mainly affected by the amount of light received throughout the day The influence of plant morphology (height and plant type) is mainly related to light quality (mainly blue light, red light, etc.). For plants that are sensitive to photoperiod, their flowering (short-day and long-day plants) is mainly affected by the duration or photoperiod of light, while plants that are insensitive to photoperiod (neutral) are most affected by the amount of light. Photosynthesis is mainly affected by the amount of light and light. Strength influence. Photosynthesis mainly occurs in the visible spectrum, (400-700nm) the strongest photosynthesis in the red light region and the blue light region. The RB ratio is mixed for color mixing, and the light necessary for plant growth is artificially synthesized. The spectrum is pure, and the spectrum is concentrated in 450-470, 615-625. Compared with ordinary plant lights, they have obvious advantages, which will radiate ultraviolet light and infrared light that are useless for plant growth, which is very wasteful.
Experts from the University of Agriculture have cultivated a batch of holly seedlings through cloning technology, and look for the most suitable "nutrient light" for plant growth according to their growth status under different color light sources. Remember to see that the holly seedlings under the purple light are the tallest, but the leaves are small and the roots are shallow. They look like malnutrition. The seedlings under the yellowish light are not only short, but the leaves look lifeless. The holly that grows under the mixed red and blue light grows best, not only is strong, but the root system is also very developed. According to reports, the red and blue light bulbs of this light source are configured in a ratio of 9:1. In addition to holly seedlings, experts also conducted light experiments with Phalaenopsis, Oncidium, strawberries, and tomatoes. The results prove that the 9:1 red and blue light is the most beneficial to plant growth.
The wavelength of the plant lamp is very suitable for the growth, flowering and fruiting of plants. Generally, indoor plants and flowers will grow worse and worse with time. The main reason is the lack of light irradiation. The LED lamp suitable for the required spectrum of plants can not only promote their growth, but also prolong the flowering period and improve the flowering of the flowers. quality. The application of this high-efficiency light source system to agricultural production such as greenhouses, greenhouses and other facilities on the one hand can solve the shortcomings of the lack of sunlight leading to the decrease in the taste of tomatoes, cucumbers and other greenhouse vegetables, and on the other hand, it can also advance the winter solanum vegetables in the greenhouse. It will be listed around the Spring Festival, so as to achieve the purpose of off-season cultivation.
