PROBLEM TO BE SOLVED: To provide a cultivation apparatus capable of cultivating plants which requires as little labor as possible while effectively utilizing natural laws and water resources.SOLUTION: A cultivation apparatus consists of a cultivation tank, a lift pump, a sprinkler which makes the lift pump circulate water and sprinkles water into the cultivation tank, and a solar panel for power generation which feeds electric power to the lift pump. The apparatus comprises: a water storage tank placed above the top surface of the cultivation tank detecting means for detecting a water amount in the water storage tank and a control unit which controls drive of the lift pump. The apparatus keeps on driving the lift pump by the information of the lower limit or less of the water amount obtained from the detecting means, and keeps on stopping the lift pump by the information of the upper limit of the water amount. Thus, circulation of water is automatized depending on a climate, and a cultivation apparatus of plants or fish and shellfish which requires as little labor as possible while effectively utilizing water resources can be provided.COPYRIGHT: (C)2015,JPO&INPIT【課題】自然の摂理と水資源を有効活用しつつ極力手間をかけずに栽培できる栽培装置を提供する。【解決手段】栽培槽と、揚水ポンプと、前記揚水ポンプによって水を循環させ栽培槽に散水する散水器と、前記揚水ポンプに給電する発電用ソーラーパネルとからなる栽培装置において、前記栽培槽の上面より上方に置いた貯水タンクと、この貯水タンクの水量を検知する検知手段と、前記揚水ポンプの駆動を制御する制御装置を備え、検知手段から得た水量の下限以下の情報によって揚水ポンプを駆動し続け、且つ水量の上限情報によって揚水ポンプを停止し続けるようにする。これによって水の循環が天候によって自動化され、水資源を有効利用しつつ極力手間をかけない植物や魚介類の栽培装置が提供できる。【選択図】 図1
