The invention provides a planting module, which is composed of a pot, a water introduction pipe, a water inlet pipe and a position limiting structure. The pot includes a bottom having a periphery upwardly extended therefrom a trunk part to define a planting area. In addition, the bottom also downwardly extends a water outlet pipe communicated with the inside and the outside of the planting area. The bottom edge of the water introduction pipe is communicated with the water outlet pipe. The top edge of the water introduction pipe is disposed above the planting area. The water inlet pipe is communicated with the top of the water introduction pipe so as to perform watering over the planting area and supply water to the water outlet pipe. In addition, the water inlet pipe may be inserted to the water outlet pipes of other planting modules to extend and assemble a planting wall with a required height. The position limiting structure includes a first insertion part at one side of the trunk part and a second insertion part at the other side thereof so that the second insertion part is matched with another first insertion part of a different planting module thereby extending in a perpendicular direction to achieve a width of the planting wall to fit the space requirements.本發明係以一體之盆體、引水管、進水管及限位結構組成。該盆體係於底板四周向上延設有胴部,用以界定出種植區,而底板更向下接出一連通種植區內外之出水管,至於引水管底端係連通出水管、頂端係位於種植區上方,進水管係接通於引水管頂端,使之能對種植區進行澆灌及對出水管注水,且令該進水管能供其它植栽模組出水管插接,俾能延伸組裝出植栽牆所需高度,至於限位結構係於胴部一側設有第一嵌部、另側設有第二嵌部,使該第二嵌部能供不同植栽模組第一嵌部對合,據以橫向併排延伸,如此即可視空間需求而任意組裝出植栽牆之寬度。10‧‧‧盆體12‧‧‧胴部121‧‧‧背板122‧‧‧拱形板13‧‧‧種植區14‧‧‧出水管20‧‧‧引水管21‧‧‧中間段22‧‧‧下段23‧‧‧上段30‧‧‧進水管31‧‧‧內孔32‧‧‧鴨嘴部41‧‧‧第一嵌部411‧‧‧弧槽42‧‧‧第二嵌部
