An upright planting system suitable for irrigation with a liquid and comprising a ring member, a plurality of filler members, and a plurality of liquid absorbing members. The annular wall member extends in an annular shape up and down, has a radial wall thickness of at least 2 cm, and defines an inner space extending upward and downward for the liquid to flow, and is formed with a plurality of inner and outer passages and communicates with the inner space. The space for the plug. The filler members are respectively disposed in the plug spaces. The liquid absorbing members are respectively disposed in the filling members, and respectively extend from the filling members into the inner space and can absorb the liquid. The invention only needs to cut the waste material generated by the annular wall member due to the formation of the plugging space, and then the liquid-absorbent member is put into the back and plugged back to manufacture, so the invention is relatively simple to manufacture. It has the advantage of being easy to produce.一種直立式栽種系統，適用於利用一液體灌溉，並包含一個環壁件、數個填充件，以及數個吸液件。該環壁件橫剖面呈環狀地上下延伸，徑向壁厚至少為2公分，並圍繞界定出一個能供該液體流動且上下延伸的內部空間，且形成有數個內外貫通並連通該內部空間的塞置空間。該等填充件分別設置於該等塞置空間中。該等吸液件分別設置於該等填充件中，並分別由該等填充件延伸至該內部空間中且能吸收該液體。本發明於製造上僅需將該環壁件因形成該等塞置空間所產生的廢料剖開，再將該等吸液件放入後塞回即可製造完成，故本發明製造上相當簡單，具有易於生產的優點。
