The present invention is a multi-structure prefabricated multi-pillar structure by installing a plant cultivation manager to maintain the standing state between the pillars in order to produce a plant cultivation manager accommodated edible plants and ornamental plants in a plurality of pillars to the desired display form It is about. The prefabricated multi-pillar structure maintains a ground state on the floor, and stands at a constant height to have a central column having a hollow volume； A plurality of auxiliary pillars arranged at equal intervals along the circumferential direction of a constant distance from the central pillar； A fixed band portion located higher than a general key is connected horizontally between the central pillar and the auxiliary pillar, and the auxiliary pillars are horizontally connected, and between the central pillar and the fixing band portion of the auxiliary pillars, and between the auxiliary pillars. A plurality of first horizontal fixing bars for fixing the center pillar and the auxiliary pillars in an upright state while maintaining a constant distance from each other； A fixing band portion is continuously connected horizontally between the center pillar and the auxiliary pillar at a position higher than the first horizontal fixing band, and between the auxiliary pillars, between the center pillar and the fixing band portion of the auxiliary pillars, and the auxiliary pillar. A plurality of second horizontal fixing bars fixed together with each other to fix the center pillar and the girder columns in an upright state while maintaining a constant distance from each other； Diagonally connected between one region of the first horizontal anchor and the other region of the second horizontal anchor and diagonally connected between one region of the second horizontal anchor and the other region of the first horizontal anchor to maintain a cross state. A cross anchor for maintaining the cross state and reinforcing the standing state by
