PROBLEM TO BE SOLVED: To provide a hydroponics apparatus capable of suppressing temperature changes of culture solution.SOLUTION: A hydroponics apparatus comprises: a main pipe a plurality of branch pipes which branch approximately from above the main pipe so as to be fluidly connected to the main pipe, and disposed at approximately the same height to each other a cultivation container disposed inside each of the plurality of branch pipes and a tank which is fluidly connected to both ends of the main pipe, and stores liquid circulating through the main pipe, the branch pipes and the cultivation containers. According to the constitution, the main pipe for supplying culture solution from the tank to the cultivation container is disposed below the cultivation container, so that the main pipe can be also buried underground together with the branch pipes and the cultivation containers disposed inside the branch pipes, and temperature changes of the culture solution can be suppressed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】培養液の温度変化を抑制できる水耕栽培装置を提供する。【解決手段】主配管と、前記主配管と流体的に接続するよう前記主配管から略上方に分岐し、互いに略同じ高さに配設された複数の枝管と、前記複数の枝管各々の内部に配設された栽培容器と、前記主配管の両端と流体的に接続され、前記主配管と前記枝管と前記栽培容器を循環する液体を貯蔵するタンクと、を備えることを特徴とする。このような構成によれば、タンクから栽培容器に培養液を供給するための主配管が栽培容器よりも下方に配設されるため、枝管及びその内部に配設される栽培容器と共に、主配管も地中に埋めることができ、培養液の温度変化を抑制することができる。【選択図】図1
