摘要: 无土栽培的营养液要循环使用,并在重复使用前采用非农药方法对其消毒。分析了循环营养液物理消毒的主要方法:紫外线、臭氧、加热、过滤、过氧化氢、氯气、碘等,以及各自的优缺点和使用范围、消毒效果;并重点对目前在实际蔬菜生产中已经有一定应用面积的臭氧和紫外线消毒法,进行了讨论,提出了循环营养液物理消毒法的研究目标和发展方向。

Abstract: Physical methods of disinfection of nutrient solution from soilless culture systems are summarized, including the use of ozonization, ultraviolet radiation, heat treatments, filtration, iodination, activated hydrogen peroxide and others. Ozonization, ultraviolet radiation and heat treatments are feasible by now. Further development in disinfection of nutrient solution is also put forward.
