The culture unit 20 is connected to the outlet end of the photosynthetic reaction unit 10, and the culture solution of the photosynthesis reaction unit 10 enters the culture unit 20, and can be cooled in the culture unit 20, and by controlling the flow rate of the culture solution in the culture unit 20 And the way to reduce or stop photosynthesis, so that the algae in the culture solution undergoes a physiological regulation program in the culture unit 20.

The culture unit 20 has an adjusting tank 21, and a plurality of first partitions 22 and second partitions 23 arranged in the adjusting tank 21. In this embodiment, the adjusting tank 21 is a rectangular tank body. 21 can be a closed tank or an open tank. The two ends of the adjustment tank 21 in the longitudinal direction can define an inlet end 201 and an outlet end 202.
