Blueberry is a new kind of world-wide small perennial fruit tree with high fruit nutritional values,rich varieties and high production benefit,which is suitable for off-season cultivation in facilities.Facility blueberry production area expanded gradually in both the South China and the North China,and the pot substrate cultivation has become the development direction nowadays.However,due to the facility shade and heat preservation measures,there are serious problem of lacking light(intensity and photoperiod)in facility blueberry production,especially in winter and spring.LED lighting is the most direct method to solve the facility blueberry light shortage.We can design the lighting scheme with best spectrum,appropriate light intensity and photoperiod to optimize light environment for blueberry growth,flower and fruit development.Then,high-yield and high-quality as well as marketing ahead of time will be achieved.This paper summarized the present situation of blueberry planting in China,analyzed the reasons of insufficient illumination,and put forward the design principles of LED light scheme.
