A plant cultivation system capable of moving a holding member for holding a plant by a simpler method. A plant cultivation system (1) includes first and second water channels (11, 12) provided at equal intervals, a moving body (16) that moves in the first and second water channels (11, 12), and a moving body (16). Moving means for moving along the first and second water channels 11 and 12. The moving body 16 includes a holding member 16a that holds the plant 3, and first and second floats 16c and 16d that are provided on the holding member 16a and float on the first and second water channels 11 and 12, respectively. .
