PURPOSE:To enable culture of plant in ideal arrangement and to improve the production efficiency by using a guide member for guiding a float from the upstream side of the flow of a culture liquid to the downstream side and temporarily mooring the float to the guide member. CONSTITUTION:The objective apparatus is provided with a guide member 34 for guiding a float 11 from the upstream-side to the downstream-side of the flow of culture liquid 3 and with a mooring device for temporarily mooring the float to the guide member according to the growing stage of the transplanted plant. The float is transferred in a state guided with the guiding member and, accordingly, the entanglement of the plants of adjacent floats can be prevented. Since the float guided by the guiding member is moored with the mooring means 40 according to the growth stage, the plant can be cultured interposing optimum spacings between the plants according to the growth to enable the culture of plant in ideal arrangement. |
