LED,as the preferred light source and means for environment control in facility horticulture,is energy-efficient,precise,long-lasting,and has high light efficiency.By controlling the light attributes such as light quality,intensity,and photoperiod,it can regulate plant photosynthesis and morphogenesis,adjust the growth and development,biomass,fruit yield,flowering and quality of horticultural crops in controlled environments.This provides benefits for supplemental lighting in greenhouses.Moreover,based on the significant benefits brought by spatio-temporal light environment control,dynamic lighting and three-dimensional lighting have emerged and are thriving,with broad prospects for application.This article summarizes greenhouse LED lighting products and application areas,introduces the concepts of dynamic lighting and three-dimensional lighting technologies,reviews the research progress in controlling plant growth,yield,flowering,and agricultural product quality through light quality,intensity,and photoperiod regulation.The paper also provides insights into the future development prospects of the greenhouse LED supplementary lighting industry.
