The wavelength of the led plant lamp is very suitable for the growth, flowering and fruiting of plants. General indoor plants and flowers will grow worse and worse with time, the main reason is the lack of light irradiation. The LED light irradiation suitable for the required spectrum of plants can not only promote their growth, but also prolong the flowering period and improve the quality of flowers. The application of this efficient light source system to agricultural production such as greenhouses, greenhouses and other facilities, on the one hand, can solve the problem that the lack of sunlight leads to the decline of the taste of tomatoes, cucumbers and other greenhouses, on the other hand, it can make the winter greenhouses jackets vegetables before and after the Spring Festival to market, so as to achieve the purpose of off-season cultivation.
Since blue is conducive to the growth of plant leaves and red is conducive to the flowering and fruiting of plants, the number of red and blue beads of this lamp can be specially made according to the user’s plant requirements for light.
Light and plant light affect plant has four forms: light quality, photoperiod and light intensity and light quantity, plant growth and yield (the plant size, the number of flowers, and other characteristics) mainly accept the influence of the amount of light in the day, plants form (height and plant type), mainly related to light quality (mainly blue, red,). Photoperiod sensitive plants are mainly affected by the duration or photoperiod of light, while photoperiod insensitive plants (neutral) are most affected by the amount of light. Photosynthesis is mainly affected by the amount and intensity of light. Photosynthesis occurs mainly in the visible spectrum, (400-700 nm) in the red light district and strongest photosynthesis in blue light LED plant growth light according to choose the growth mechanism of the optical activity of plant photosynthesis, using LED light source, carried out in accordance with the scientific RB ratio of mixed color, synthetic needed to make plants grow light, pure spectrum, spectrum is concentrated in the 450-470615-625. Compared with ordinary plant lamp obvious advantage, ordinary plant lamp can radiate the ultraviolet light that is useless to plant growth and infrared light, waste is very big.
Agricultural university experts through cloning technology to cultivate a batch of Holly seedlings, according to their growth state in different color light source, to find the most suitable for plant growth of “nutrient light.” Remember, Holly seedlings in purple light, the highest, but small leaves, shallow roots, a look of malnutrition. Not only are young plants dwarfed by yellow light, their leaves look lifeless. Holly grows best under a mixture of red and blue light. It is strong and has a well-developed root system. According to introducing, the red bulb of this kind of illuminant and blue bulb are in accordance with 9:1 scale configuration. In addition to Holly seedlings, experts also used phalaenopsis, Wenxin orchid, strawberry, tomato light experiments. It turned out that red and blue light at 9:1 was most beneficial for plant growth.
