In a completely enclosed space, without sunlight and soil, plants thrive. When the reporter from Aladdin News Center walked into Guangdong lvai Biotechnology Co. , Ltd. , the first thing that came into view was a high-tech plant factory: dust-free, sterile and fully enclosed, with precisely controlled light, air, temperature, humidity and nutrient solution, several layers of special shelves are filled with vigorous vegetables, rare Chinese herbal medicines, melons and fruits, flowers and other plants, the vegetables produced can be eaten directly. Mr. Hong Yannan, chairman of guangmingyuanguang Technology Co. , Ltd. and Guangdong lvai Biotechnology Co. , Ltd. , is no stranger to plant factories and is one of the topics that are currently in the limelight. As early as 2010, guangmingyuan, who has been deeply engaged in the field of lighting for 12 years, began to study plant lighting. In 2015, guangmingyuan LED and launched Guangdong lvai Biotechnology Co. , Ltd. , specializing in the production of LED plant lighting lamps, providing LED plant factory planning, design and construction scheme as well as a complete set of plant growth containers, it is one of the few plant lighting manufacturers with a certain level of development in China. LED plant lighting in Guangdong lvai plant factory: a light formula that can be accurately controlled according to Mr. Hong Yannan, the plant factory is a systematic project, it involves disciplines in many fields such as optics, nutrient solution and space management, but these fields cannot be separated independently and need to be considered comprehensively from different dimensions. As one of the core production factors of plant factories, Guangdong lvai biology relies on the lighting foundation of its parent company, guangmingyuan, to extend from the perspective of light and study the influence of light on plant growth, and repeated verification. As for plant lighting, different varieties and different growth stages have very different requirements for spectrum. It is necessary to find a light formula that produces a good performance ratio for plant growth. In Guangdong lvai plant factory, at present, Guangdong lvai biology has reached strategic cooperation with many scientific research institutions and agricultural institutions in Guangdong, Yunnan, Beijing and other places, with a total of 12 patents granted and accepted, more than ten kinds of plant lighting products including tissue culture lamp, seedling lamp, plant growth lamp, high-power plant lamp, plant-to-plant fill lamp, etc. have been introduced; In close cooperation with its parent company guangmingyuan, relying on guangmingyuan's excellent production capacity and strict quality control capability, it has produced LED plant lighting products that accurately meet the requirements of light formula.
