The utility model relates to a base structure of a plant potting plant, which mainly comprises a base part, a fixing groove extending upward from the base part to form a three-dimensional potting plant for fixing, a positioning hole arranged at the bottom of the fixing groove for fixing a water return pipe, at least a water storage wall surrounding one side of the base part, so as to form a water storage space on the base part, and then a water storage space is arranged in the water storage space Set at least one filter element.With the above structure, the integrated clamping tank can be used to hold the three-dimensional potted plants, so as to enhance the overall structural strength, directly recover the water to the water storage space, and install the water return pipe through the positioning hole, so as to save the water source and reuse, and keep the water quality of the water storage space clean with the filter element, so as to avoid the motor blocking, thereby increasing the practicability and convenience of the three-dimensional potted plants. u3002本新型為有關一種植物盆栽之底座結構，主要結構包括一基底部、一由該基底部向上延伸形成供卡固一立體盆栽之卡固槽、一設於該卡固槽底部供固定一回水管之定位孔、至少一環繞於該基底部一側之儲水壁，以於該基底部上形成一儲水空間，再於該儲水空間內設置至少一過濾元件。藉上述結構，以一體成形的卡固槽容置立體盆栽，而提升整體的結構強度，且可直接回收水分至儲水空間中，並透過定位孔安裝回水管，達到節約水源、重複利用之目的，並以過濾元件保持儲水空間之水質潔淨，避免馬達阻塞，藉此增加立體盆栽的實用性及便利性。
