Abstract The health level of seedlings is closely connected with the growth and development
of plant after fix planting，and also with crop yield and quality. Research and development for safe，
environment friendly，and economic efficient cultivation technology is an important issue in modern
facility agriculture．Light environment control technology is a new energy saving，environment
protecting，economical effective，simple and convenient method．This paper summarized the research
progress and application of light environment control technology in light intensity，light quality and
photoperiod three fields in vegetable seedling culture，and prospected the application of LED light
source for vegetable seedling cultivation in factory．
