There are two main problems in the use of nutrient solution for soilless cultivation: one is that nutrient solution is easy to be anoxic; the other is that the nutrient solution is easy to contact with pathogens when it is recycled.
Micro nano bubble technology is to use micro nano bubble rapid generation device to dissolve gas into water quickly and efficiently to produce micro nano bubbles. The remarkable characteristics of micro nano bubbles are that they rise slowly in water, stay for a long time, produce self-compression, have high solubility in water, and have physiological activity to promote plant growth. Therefore, micro nano bubble technology is considered to be very suitable for application in hydroponic cultivation system.
In addition, compared with other aeration methods, the micro nano bubble technology is less affected by temperature, so it has significant advantages in summer and other high temperature seasons. The micro nano bubble technology is used to dissolve oxygen into the nutrient solution to form micro nano bubble oxygen-enriched water to oxygenate the nutrient solution. The micro nano bubble technology is used to dissolve ozone into the nutrient solution to form micro nano bubble ozone water, and the ultraviolet sterilizer exerts a synergistic disinfection effect on the nutrient solution.
The micro nano bubble technology can effectively dissolve oxygen and ozone in water, and the generated micro nano bubbles have slow-release effect, which can prolong the retention time of oxygen and ozone in water and improve the utilization rate; it can realize the dual functions of increasing oxygen and disinfection, which can not only oxygenate the nutrient solution, but also disinfect the nutrient solution, effectively reducing the accumulated investment cost of a single equipment.
