PROBLEM TO BE SOLVED: To provide a cultivation system that can prevent cultivating plants from saprophytic bacterial infection, replant failure, etc., and reduce the running cost, facility cost, etc.SOLUTION: Cultivation containers 10a1 to 10a4 individually house plants 12Pa1 to 12Pa4 and are connected between a distribution supply passage 14 and discharge passage 16 through branch supply pipes 20U1 to 20U4 and branch discharge pipes 20D1 to 20D4. The water level LH of a nutrient solution LQ in each of the cultivation containers 10a1 to 10a4 is kept at a predetermined level. After a waste liquid from the discharge passage 16 is processed by a waste liquid treatment device 22, the processed nutrient solution is returned to the cultivation containers 10a1 to 10a4 through a recovery pipe 24.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】栽培システムにおいて、栽培する植物の雑菌感染、連作障害等を予防でき、しかも、ランニングコスト、設備費用等を低減できること。【解決手段】栽培用容器10a1~10a4が、植物12Pa1~12Pa4をそれぞれ個別に収容し、分岐供給管20U1~20U4、分岐排出管20D1~20D4を介して分配供給路14と排出路16との間に接続されるもとで、栽培用容器10a1~10a4内の養液LQ´の水位LHが所定の値に維持され、排出路16からの廃液が廃液処理装置22に処理された後、処理された養液が回収管24を通じて栽培用容器10a1~10a4に戻されるもの。【選択図】図1
