<p>PROBLEM TO BE SOLVED: To realize excellent cultivation and to improve workability, since a conventional cultivation assistant device, such as a heating piping, has problems: that the device cannot effect on entire plant which grows in vertical direction since the device has a construction where the device extends in forth and back direction and a construction where the device topically effecting on a point near the growth point of the plant; and that it is thus considerable that light receiving is restricted and operation from a passage is obstructed due to a large-scale structure thereof in which, for example, cultivation assistant devices extending in forth and back direction are arranged on the same cultivation line but vertically different positions and effects on the plants planted at the vertically different positions.SOLUTION: A cultivation facility comprises a plurality of cultivation units for cultivation of plants on a pair of right and left cultivation lines in a manner where the cultivation units are arranged in parallel between the right and left cultivation lines. A passage (9) in forth and back direction is arranged between each right and left pair of the cultivation units. Cultivation assistant devices (121, 122) suspended from upper side of a gap between the pair of right and left cultivation lines and extending in vertical direction are arranged in a manner where the devices may move in forth and back direction.</p> |
