PROBLEM TO BE SOLVED: To provide an elevated culture apparatus capable of precisely managing the amount of a liquid to be supplied in accordance with the progress of photosynthesis of plants cultivated on a high cultivation bench set in a greenhouse.SOLUTION: According to the present invention, there is provided an elevated culture apparatus 30 in which a liquid supply unit 31 is controlled to carry out an operation of supplying water, a nutrient solution, etc. in a predetermined supply amount per unit time in a predetermined time period of a day to strawberry seedlings 23 through a supply pipe 4 arranged along an elevated cultivation bench 1. The elevated culture apparatus 30 is supplied with a measured value of the drained amount of a drained liquid, which flows from a drained liquid amount-measuring part 33 and is recovered to a drainage recovery part 32 along a drainage groove 14 at the bottom of the elevated cultivation bench 1. The elevated culture apparatus 30 increases or decreases the amount of a liquid to be supplied so as to maintain the drained liquid amount at a predetermined set amount based on the drained liquid amount.SELECTED DRAWING: Figure 3
