The system has the advantages of convenient and fast construction, less moisture evaporation, fast temperature rise under the low-temperature condition, low facility cost and the like. However, the system does not involve stirring of the algae liquid, and further improvement of the culture effect is influenced.

Utility model 202120393960.4 discloses a little algae liquid's disturbance device, takes local heavy object in the plastics section of thick bamboo area, leans on wind-force to drive to let the section of thick bamboo area move and then drive algae liquid and take place the action, forms to stir. However, this method can only produce local shaking, and the shaking range of the algal solution is small, so that it is difficult to control the effect of shaking.
