PURPOSE:To increase the number of cultured plants per unit area without causing the withering of the plant, by supplying and circulating a culture liquid to the top of a culture cylinder which is three-dimensionally supported on a post. CONSTITUTION:An elastic foamed material 2 containing a seed is pushed into a circular culture cylinder A1 through a pushing opening 4 opened in the direction of length. A plurality of the culture cylinders A1 are supported by supporting holes 6a of supporting posts 6 in multiple stages while keeping horizontal state and interposing prescribed spaces in vertical direction. An induction hose 10 is connected to a connection tool 8 attached to the bottom of the culture cylinder A1. The culture liquid in the top culture cylinder A1 is transferred to the lower culture cylinder A1 by the head and returned to the culture liquid tank 12 from the bottom culture cylinder A1. A pump P is actuated to supply the culture liquid 14 in the tank 12 to the top culture cylinder A1 through a suction pipe 20 and a hose 22 and the supplied culture liquid is successively transferred and circulated through the hose 10 to the lower culture cylinders A1. |
