Abstract：Facility sweet cherry is an important deciduous fruit tree with high added value in the north of China.Sweet cherry is a short-day and light-loving crop.During winter and spring,some key developmental stages,e.g.the flower bud differentiation,functional leaf development,flowering and fruiting,fruit development and fruit color-changing maturity of protected sweet cherry are often affected by low light stress.It is very important to overcome the low light and low illumination by adopting effective light environment control methods to guarantee the high yield and high quality of sweet cherry.Reports showed that the three-dimensional space guarantee of light intensity,light quality and light period of the tree canopy can be strengthened by supplementing artificial light,laying reflective film and erecting light transmission film,and the ability of light interception and utilization of the tree canopy as a whole can be improved.In this paper,the characteristics of light environment and the requirements of light environment control of sweet cherry canopy in facility are summarized.Based on the requirement of emergency and routine lighting,LED lighting strategy for sweet cherry production in facility was proposed.
