LED light promotes plant growth in vegetable greenhouse

Besides lighting, LED can realize optical communication, which is amazing enough Today we are going to tell you that LEDlight can also promote plant growth With the crisis of overcapacity in the first generation of le d simple lighting, more and more Dongguan le d began to turn to the field of special lighting, using le d to create a small "sun" for indoor plants Biao Jun optoelectronics introduces Taiwan technology to launch the LE D plant growth lamp module, and has ten years of experience in the photoelectric industry, Shenzhen Wright, also moved from Shenzhen to Dongguan, and began to engage in LE D biological lighting It is well known that plants need light to grow The biology textbook also said that only sunlight can help plants to complete photosynthesis, while Shi Guangdian, deputy general manager of shenlaite, told reporters: "LEDlight can simulate specific spectral components of sunlight, which has been widely recognized by the botany community." "During photosynthesis, most of the chlorophyll absorbs red light, blue light and violet light, and the light wavelength is about 400-700nm," Shi Guangdian said LED is different from incandescent lamp, the chip light is single, can provide a specific spectrum of a certain growth stage for plants directly The wavelength of 440-490nm is blue light, which can promote the growth of green leaves; the wavelength of 600-700nm is red light, which is helpful for flowering and bearing fruit and prolonging flowering period; the wavelength of 300-440nm is violet light and ultraviolet light, which are the main light energy to promote the formation of plant pigments, and directly affect the absorption of phosphorus and aluminum, the formation of vitamin D, cuticle, and the accumulation of dry matter "Our concept of plant factory is to make vegetable greenhouses into factory workshops Each workshop has different LED lighting Soilless plants can be moved to different workshops according to the needs of different growth periods." According to Shi Guangdian, at present, the laboratory in Zhuhai has begun to cultivate The growth of plants can be "fast forward" or slowed down by LEDlight The green and yellow light with a wavelength of 500-600nm can inhibit the activity of chloroplasts and reduce photosynthesis The chip also relies on imports to match the solution The principle is so simple Now on Baidu search, you will find that many led enterprises in Dongguan have successively launched monochromatic light le d to promote plant growth "The competition in the traditional le d lighting market has become white hot Biolighting is a new field, and as long as you understand the spectral law, it is better to apply and promote." According to an analysis by a senior manager of LED enterprise and an investigation by a reporter from Nandu, although these LED lighting have transformed the battlefield, the chip source still mainly relies on imports Shenlaite has obtained the first level agent authorization of Samsung led, and puma Jun has introduced Taiwan chips The enterprise is still fighting for solutions In fact, led bioluminescence can also eliminate the living space of pests and diseases, minimize the use of synthetic materials and reduce the pollution index According to Shi Guangdian, shenlaite will first complete the basic light source test of the plant factory series, and then continue to develop three series of animal factory series, family health series and public health series by using LED light [actuarial account] it does not waste spectrum and save electricity, which is better than fill light In fact, before the emergence of LED, modern horticultural and plant factories had "fill light" technology, which used fluorescent lamp, high-pressure sodium lamp, etc these light sources contain a large proportion of infrared and green light components "In fact, all plants need is red light and blue light Most of the light energy is wasted." Shi Guangdian said that LED plant growth lights can emit red and blue light that plants need, so they are extremely efficient It can be said that the power of LED plant growth lamp is several watts, equivalent to tens of watts or even hundreds of watts of traditional lighting effect In addition, LED can save more than 90% of the electric energy compared with the traditional lamp, and the operation cost is greatly reduced LED can control the growth speed of plants, prolong the flowering period of flowers and plants, and accelerate the results of cash crops In addition, it can also be used for animal breeding, using specific wavelength led to promote animal production, reduce disease, reduce the use of feed additives and hormones, etc.
