The vegetables that the Shenzhou 13 astronauts ate before their expedition came from the LED plant factory

On October 16, the Shenzhou 13 manned spacecraft was ignited into space. In order to better ensure the daily food for the astronauts of the Shenzhou series of manned missions, the Jiuquan Satellite Launch Center built a unique "vegetable field" in March this year. "--Artificial light type vegetable factory. This factory mainly uses LED plant spectroscopy technology, nutrient solution cultivation technology, automated environmental control technology and intelligent equipment to grow high-quality and high-yield vegetables in the purification plant.

"Large size, good appearance, no pesticides." Compared with traditional vegetable planting, plant factories show obvious advantages: they do not need to occupy a large area of ??land, and are not restricted by environmental conditions, and can be used in urban parking lots, indoors and other places throughout the cycle , Mass production.

With this benefit, domestic LED plant lighting has also ushered in development. Recently, some related companies have begun to enter the domestic plant lighting field. As the first stock of plant lighting power supply, Songsheng shares said that the current plant lighting power supply orders are good, and it will actively expand the domestic plant lighting power supply market in the future.

A few days ago, the Daily LED reporter interviewed the "Top 25 Plant Lighting Companies in China's LED Industry in 2020" on related issues in the field of plant lighting. Most companies expressed optimism about the domestic LED plant lighting market.

Liu Yongji, general manager of Wuxi Yiming Optoelectronics Co., Ltd., a holding subsidiary in the field of plant lighting, said that on the one hand, the increase in global population will inevitably lead to insufficient food supply from cultivated land, and intensify the contradiction between population and land. Plant factories can well alleviate this contradiction; on the other hand, with people’s pursuit of a healthy and green life, the demand for pollution-free vegetables will further increase, and the use of plant lighting will also be expanded. Whether at home or abroad, from the perspective of development, the market prospect of plant lighting is broad.

Wang Zhenhua, general manager of Shenzhen Sunray Biotechnology Co., Ltd., said that in the current domestic plant lighting field, most small and medium-sized enterprises invest in plant lighting only on the independent research and development of a few plants such as tomatoes and Chinese cabbage. Large companies actively invest, and the future market space is broad.

"Our offspring are less and less farming, so the industrialization of planting is imperative." Dong Hongliang, chairman of Guangdong Weizhaoye Optoelectronics Energy Saving Co., Ltd., said that the next three years will continue to focus on hemp planting products. But in the long run, this industry is driven by high-performance light sources, drivers, and high-dimensional product design concepts, and the future of the plant lighting industry has a bright future.
