摘　　要：采用红蓝组合(2∶3)LED灯对设施栽培蔬菜全生育期进行补光处理,研究其对不同蔬菜坐果率以及产量的影响。研究结果表明,LED灯补光处理能不同程度地提高供试蔬菜作物的坐果率;可显著增加瓜类蔬菜的主蔓雌花数,提高其单果质量和667 m2产量,其中节瓜最为显著,其单果质量和每667 m2产量分别提高5.3%和15.6%;LED补光处理对茄子影响也较明显,单果质量和每667 m2产量分别提高7.6%和7.8%,但对番茄和辣椒影响不明显。With the ratio of red and blue light emitting diodes（LED） of 2∶3,the paper studied the irradiation effects of the LED lights on the fruit setting rate and yield of different crops in greenhouse during their whole growth period.The results showed that,the LED lights treatment could improve the fruit setting rate of the tested crops in various degree,andsignificantly increase the female flower number on the main stem of melon crops.The fruit weight and yield of melon crops were also increased.The fruit weight and yield of chieh-qua were significantly increased by 5.3% and 15.6%,and the fruit weight and yield of eggplant were also significantly increased by 7.6% and 7.8% respectively in the LED lights treatment,but the LED lights treatment had no significant effects on tomato and pepper.
