Abstract:

【Objective】 To summarize and analyze the research status and progress of LED supplementation technology for vegetables at home and abroad in the hope of providing a theoretical basis for the application of LED fill light technology in the efficient production of facility vegetables in China.【Methods】 Related literature in domestic and foreign were collected, and meanwhile, these literature were sorted and analyzed.【Results】 LED light source was an ideal light source for facility agricultural production, appropriate light formula (light quality, light intensity and light duration and cumulative daily light amount) could significantly improve the dry matter quality and strong seedlings index of vegetables seedling.Light supplementation at the top and between plants could improve the canopy light distribution and enhance the overall photoeynthesis of plants in long season cultivation.It was an effective way to accurately control the dynamic light environment by combining the light filling method with the cultivation environment parameters to achieve green, high quality and efficient production of facility vegetables.【Conclusion】 Artificial light supplementation is an effective way to improve the greenhouse light environment and solve the unfavorable light factors such as weak light and insufficient light time in winter vegetable production.Through the combination of light formula, vegetable varieties and cultivation environment optimization, the production efficiency of vegetable facilities can be comprehensively improved.
