PURPOSE:To enable the supply of culture solution and oxygen alternately to root in high efficiency with low energy consumption, by culturing a plant in a manner so as to alternately contact its root with air and culture solution. CONSTITUTION:A setting panel 2 is positioned at a level higher than the culture solution level 4 and a plant 3 is planted on the panel. The surface of the solution is waved with an oscillation disk 1 placed on the surface 4. The plant 3 is supplied with the culture solution and oxygen by the waved surface 4 of the solution. |
