摘　　要：采用简易设施水培法筛选得到适合在海南水培种植的高产生菜品种——罗马生菜,同时研究不同通气处理对生菜平均单株质量和品质的影响。结果表明:通气处理可显著降低生菜叶片的硝酸盐、纤维素含量,提高维生素C、可溶性糖和可溶性蛋白质的含量,其中以7:00～19:00每隔4 h通气2 h的处理对提高生菜平均单株质量和品质效果最好。Roman lettuce is the best hydroponically grown high-yielding lettuce cuhivar in Hainan. The effect of different airing treatments on the yield and quality of the lettuce were studied by hydroponics with simple facility. The results showed that following the airing treatment, yield, vitamin C, soluble sugar and protein content were relatively high, nitrate and cellulose content were relatively low. Taking yield and quality as the measurement index, the optimal airing treatment for ＇Roman lettuce＇ under hydroponics was every 4h aerated 2 h（7： 00-19： 00）.
