摘　　要：【目的】探究充氧微/纳米气泡水在设施蔬菜栽培应用的可行性。【方法】以普通自来水作为对照,以两种溶氧浓度(20和30 mg/L)充氧微/纳米气泡水为处理,进行不同灌溉用水条件下的白萝卜对比栽培试验,观测其生长及相关品质指标。【结果】与对照组相比,低溶解氧浓度下的根长、根粗、经济产量、生物产量以及VC含量和可溶性糖含量分别增加了4.8%、4.1%、3.5%、4.1%、9.9%和5.8%;高溶解氧浓度下上述指标分别增加了13.7%、5.6%、13.7%、15.1%、22.5%和9.3%。【结论】充氧微/纳米气泡水对白萝卜的生长发育以及部分品质指标有明显的促进作用,且高溶解氧浓度的促进效果更加突出。该技术在设施蔬菜栽培领域应用是可行的,为设施蔬菜的安全生产提供了一种有效的物理手段。[ Objective] The research aims to study the feasibility of application of oxygenated micro/ nano - bubble water in the field of protected vegetable cultivation. [ Method ] White radishes were cultivated with different kinds of irrigation water, i.c. plain tap water was used as a control, two kinds of oxygenated mi- cro/nano bubble water with different dissolved oxygen concentration （20 mg/L and 30 mg/L） were used as treatment groups. The growth and quality of different groups were investigated. [ Result ] Compared with the control group, the root length and diameter, economic and biological yield, content of VC and soluble sugar of the low dissolved oxygen concentration group were increased by 4.8% , 4.1% , 3.5%, 4.1% , 9.9% and 5. 8% respectively; and meanwhile, the values of high concentration group were increased by 13.7% , 5.6%, 13.7%, 15. 1%, 22.5% and 9.3% respectively. [ Conclusion] Oxygenated micro/nano - bubble water benefited the growth and development as well as some quality indicators of white radish, and the effect of water with high dissolved oxygen concentration was more effective. The results illustrated the feasibility of application of the technology in protected vegetable cultivation, and provided an effective physical means for the safetyproduction of protected vegetable.
