PROBLEM TO BE SOLVED: To provide an efficient apparatus and method for supplying carbon dioxide dissolved water and growing water with dissolved carbon dioxide, which are to be applied to plants in greenhouse cultivation and a plant factory, and algae of a bioreactor.SOLUTION: The apparatus and method for supplying carbon dioxide dissolved water or growing water with dissolved carbon dioxide use a pump which serve both for supply solution circulation and solution sending, and attached with a switching cock for solution sending to the outside, and an aspirator or a microbubble generating nozzle, in a carbon dioxide dissolving tank with a sealable cover or a supply cock, supply carbon dioxide into the carbon dioxide dissolving tank followed by circulating carbon dioxide and water or growing water, detect the saturated state of carbon dioxide in the carbon dioxide dissolving tank with a carbon dioxide variable flow meter or a bubble counter, and stop carbon dioxide supply followed by switching the switching cock to a solution sending side so as to send solution to the outside.COPYRIGHT: (C)2012,JPO&INPIT【課題】本発明はハウス栽培や植物工場の植物や、バイオリアクター等の藻へ施用する炭酸ガス溶解水や炭酸ガス溶解の育成水の効率的な供給装置および供給方法を提供する。【解決手段】密閉できる蓋または供給用コックのついた炭酸ガス溶解槽で、外部への送液用の切り換えコック付の給液循環及び送液の兼用ポンプとアスピレータやマイクロバブル発生用ノズルを用い、炭酸ガス溶解槽内に炭酸ガスを供給し、炭酸ガスと水または育成液を循環させ、炭酸ガスの面積式フローメーターやバブルカウンターで炭酸ガス溶解槽の炭酸ガスの飽和状態を検出し、炭酸ガス供給を止め、切り替えコックを送液側にし、外部に送液することにより、炭酸ガス溶解水または炭酸ガス溶解の育成液を供給する供給装置と供給方法。【選択図】図1
