摘　　要：研究了LED株间补光对番茄叶片质量、光合作用和果实品质的影响。结果表明:LED补光使番茄上部、中部和下部叶片单位叶面积鲜重明显增加,光合作用增强;同时,LED补光增加了果实中可溶性固形物含量、可溶性糖含量、糖酸比、VC含量和VE含量,并且果实品质有了明显提高,果实采收期提前5d。The effects of LED supplementary lighting among plants on leaf quality, photosynthesis and fruit quality of tomato were studied in greenhouse. The results showed that tomato leaf fresh mass per unit of the upper, middle and lower parts increased obviously, and the photosynthesis enhanced after the treatment of LED supplementary lighting;Soluble solids content, soluble sugar content, sugar acid ratio, VC content and VE content increased also. Compared with the control, the fruit quality was obviously improved, and the fruit harvest time was 5 days in advance.
