The utility model relates to a tray structure which can form a planting tower.In particular, there is a planting space on one side of the planting hole tray.On the other side of the disc body of the planting hole,The lower position is provided with a hollow assembling inner circular shaft sleeve and an assembling outer circular shaft sleeve.The set-up inner circular shaft sleeve is provided with a convex tenon.The outer circular shaft sleeve of the assembly is provided with a plurality of equally divided concave tenons.So that the concave tenon of the outer circular shaft sleeve and the convex tenon of the inner circular shaft sleeve of the lower planting hole disk can be combined into one.The inner wall of the two groups of inner circular shaft sleeves and the outer circular shaft sleeves are connected by a plurality of strengthening ribs, and a strengthening fitting assembly vertical shaft tube with hollow inner part is arranged.It is used for docking when setting.In this way, a plurality of planting hole trays are arranged in an orderly manner from the top to the bottom.A spiral column plant tower was formed by staggered deployment.It is characterized by.一種可以組成植生塔的盤體結構，尤特指植栽穴盤體一側設有栽種空間，該植栽穴盤體另一側的上、下位置處設有內部呈中空的組立內圓軸套筒與組立外圓軸套筒，該組立內圓軸套筒設有一凸卡榫，該組立外圓軸套筒設有複數個等分的凹卡榫，讓上一層的植栽穴盤體可以利用組立外圓軸套筒的凹卡榫與下一層的植栽穴盤體其組立內圓軸套筒的凸卡榫套接卡合成一體，該二組立內圓軸套筒與組立外圓軸套筒的內壁利用複數個強化隔肋連接設有一內部呈中空的強化配件組立軸管，做為套設時互相對接之用，藉此將複數個植栽穴盤體由上依序盤旋而下互相堆疊，交錯展開組裝成一螺旋狀的柱體植生塔，為其特徵者。
