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 3COPYRIGHT: (C)2018,JPO&INPIT【課題】温室内に設定された高設栽培ベンチで栽培される植物の光合成の進捗状況に即して給液量を精度良く管理可能な高設栽培装置を提供すること。【解決手段】高設栽培装置30は、給液部31を制御して、高設栽培ベンチ1に沿って配置した給液管4を介して、イチゴの苗木23に対して、1日のうちの所定時間帯において単位時間当たり所定の給液量で水、養液などの給液動作を行わせる。高設栽培装置30には、排液量測定部33から、高設栽培ベンチ1の底の排水溝14に沿って流れて排液回収部32に回収される排液の排液量の測定値が供給される。高設栽培装置30は、排液量に基き、当該排液量が予め定めた設定量に維持されるように給液量を増減する。【選択図】図3
