<p>In the apparatus of the present invention, a culture medium is caused to permeate a medium support (10) made of a porous or fibrous material so as to nutriculture plants (T) implanted on the supports (10). In this case, the medium support (10) is put in a seedling raising chamber (20) kept under the sterile state and is put on a liquid exchanging apparatus (60) having a liquid exchange function inside this seedling raising chamber. The liquid exchanging apparatus (60) supports (permeates) the liquid (primarily, a culture solution) supplied from an external culture solution feeding apparatus (50) into the medium support (10) and discharges the liquid supported by the medium support (10) by utilizing capillary, for example, in accordance with the state of its liquid discharge portion (62). In this manner, the culture solution to be given to the plants (T) is exchanged automatically by utilizing the liquid exchange function of the liquid exchanging apparatus (60) through the medium support (10).</p> |
