以生菜（Lactuca sativa L.）为试验材料，研究了两种去除水培营养液中细菌的方法（紫外线照射法和亚微米过滤法）的效果。生产这两种方法都能有效地去除细菌;但是，在高强度下，紫外线消毒器显着抑制了在处理过的溶液中生长的植物的生产。较低强度的紫外线或亚微米过滤器去除细菌似乎略有促进植物生长，但没有表现出一致的，统计学上显着的效果。
Two methods of removing bacteria from hydroponic nutrient solution [ultraviolet (UV) radiation and submicronic filter] were evaluated for efficiency and for their effects on lettuce (Lactuca sativa L.) production. Both methods were effective in removing bacteria; but, at high intensity, the ultraviolet sterilizer significantly inhibited the production of plants grown in the treated solution. Bacterial removal by lower intensity UV or a submicronic filter seemed to promote plant growth slightly, but showed no consistent, statistically significant effect.
