PROBLEM TO BE SOLVED: To provide a multistage-type cultivation device which has a simple configuration, is capable of rectifying air flow in a closed-type structure of a cultivation chamber, and evenly adjusting temperature and humidity inside a cultivation chamber.SOLUTION: There is provided a multistage-type cultivation device S in which a plurality of multistage-type shelves 2, 2 are arranged inside a closed-type structure 1 being a closed space. A plurality of air conditioners 3, 3 are arranged at an upper end part of an inner side face wall of the closed-type structure 1 in such a manner that their cool air discharge ports face to each other, the plurality of multistage-type shelves 2, 2 are arranged in the state where the shelves have predetermined gaps K1 extending in a vertical direction such that their longer direction goes along a facing direction of the plurality of air conditioners 3, 3. The predetermined gaps K1 are arranged directly below a position where cool air discharged from the facing air conditioners 3, 3 collide.SELECTED DRAWING: Figure 2 |
