The present invention relates to a water holding cultivation method and a water holding cultivation device for plant cultivation. The device comprises a ridge unit including several independent water holding divisions several water supply units respectively mounted in the water holing divisions of the ridge unit and, a root covering unit covering on top of the ridge unit and the water supply units for plant growth. The cultivation method utilizes the aforementioned device and includes the steps of making ridges on a vacant land establishing divisional water supply system and, soil covering, etc. The design for the cultivation method and device may enable the water supply being independent and underground, such that the water may be independently supplied to each division and near the root of the plant to be effectively utilized, and it is convenient to manage by divisions for the plants cultivated on each of water holding divisions.一種保水栽培方法及保水栽培裝置,用來栽種植物,該裝置包含一個包括數個獨立之保水區域的田埂單元、數個分別安裝在該田埂單元之保水區域內的供水單元,以及一個鋪蓋在該田埂單元及該等供水單元上方並供植物生長的覆根單元。所述栽培方法則是利用前述裝置,在一空地上進行造埂、建立分區供水系統,以及覆土等步驟。上述栽培方法及裝置的設計,可以讓水源的供應獨立並地下化,使水源能夠獨立分區供應,並且鄰近植物的根部而被有效地運用,同時方便分區管理栽種在各個保水區域上方的植物。1...造埂單元10...邊架11...造埂座111...通道112...圍繞壁113...平壁部114...弧壁部12...擋水布13...保水區域2...供水單元21...供水管211...水道212...管壁3...覆根單元31...粗沙層32...種植土層
