Description
本発明の水耕栽培装置1では、培養液2中のイオン成分バランスの変動を抑えるためには、培養液2中のイオン成分をなるべく初期値に近い状態で推移させることに着目した。具体的には、本発明の水耕栽培装置1には、培養液循環経路5において、培養液2の一部に対し、該培養液2中の水分を除く成分の合計100質量%に対して、50質量%を超える該成分を培養液循環経路5外に排出させる分離手段6を有する構成とした。従来、培養液2はそのまま培養液循環経路5に戻していたのに対して、本発明では、従来とは逆に、培養液2中の水分を除く成分のうち一部の割合の成分を廃棄(排出)させることで培養液2中のイオン成分バランスの変動を抑えている点に特徴がある。
