At Hall 3 of the International Expo City in Western China, a group of booths were separated by several layers of lattices, covering the soil with green vegetables. "This is the use of LED lights to fill the light, the growth cycle is much shorter." Booth director, Sichuan Xinli Light Source Co., Ltd. Wang Lin introduced the International Trade Division.
 
How can LED lights for lighting promote the growth of vegetables? "Plant growth depends on photosynthesis, LED lamp is to use a low-cost way to extend the time of plant growth every day." Wang Lin said that lettuce, for example, each morning and evening light 3.5 hours, the original two months of the growth cycle can be shortened to 20 days to 30 days. According to different fruits and vegetables such as cherries, strawberries, etc., the lamp will be adjusted accordingly to suit its spectrum.
 
This type of LED light can be used directly as an agricultural light source, allowing agricultural plants to become a reality - vegetables can be housed in layers through a layer of plaids, entirely relying on LED light sources. "It can greatly save land and achieve efficient and controllable vegetable production." Wang Lin said. At present, the technology has gone out of the country and has been implemented in Singapore and Canada. Shandong Shouguang has also built a 600,000-mu greenhouse that uses this LED lamp.
