Abstract：There are mainly two problems in use of nutrient solution in soilless cultivation: one is hypoxia of nutrient solution, the second is pathogens which easily contaminate during the recycling of nutrient solution. This study compares the current methods of oxygen-increased and disinfection of nutrient solution, analyses the using range and advantages and disadvantages, and puts forward the oxygen-increased and disinfection of nutrient solution aerated by Micro-nano bubbles, introduces in detail the principle, advantages, scope of use and the popularization and application of this technology, in order to provide reference for oxygen-increased and disinfectant technology of nutrient solution in soilless cultivation.
