Chinese Academy of Agricultural Sciences has developed a special light source for plant LED and plant LED light source system

Recently, environment and sustainable development in agriculture, Chinese Academy of Agricultural Sciences researcher Yang Ji Chang presided over the completion of the "LED plant source energy efficient production of key technology research and application" by the experts organized by the Ministry of agriculture in Beijing.

Yang Qichang introduction, the photosynthesis of plants is the use of 610 - 720 nm wavelength (660 nm wave) orange light, the light energy absorbed about physiological radiation around 55%; followed by 400 - 510 nm wavelength (450 nm wave) blue violet, accounted for about 8%. Therefore, it is necessary to develop an artificial light source based on the two bands, especially the wave crest, which can greatly improve the utilization rate of light energy. The emergence of LED light source provides the possibility to achieve this goal.

The research group has developed light quality, light intensity, adjustable frequency, and has the advantages of high temperature and high humidity environment of the plant and plant LED special light source factory LED light source system, the specific needs for plant breeding, tissue culture, vegetables and medicinal plants planting, greenhouse and other uses of light illumination, developed with red and blue light LED is the main component of intelligent LED light source and light environment can be adjustable, easy to install the LED flexible lamp belt, lamp, lamp board and other series, and through the combination of LED and solar photovoltaic power generation technology, significantly reducing the energy consumption of the system. The combination of red and blue LED light on the mining before the implementation of 2 - 5 day hydroponic vegetables short-term continuous illumination and improve the comprehensive quality of leafy vegetables, and combined with the nutrient solution control technology, experiment shows that to reduce the nitrate content, improve leaf water soluble sugar and vitamin C content, solved the quality control problem of soilless culture the.
