A kind of multilayer plant cultivation device,System comprising a upper layer cultivating container,Bottom cultivating container and a hollow fixed cylinder,The upper layer cultivating container,Bottom cultivating container and a hollow fixed cylinder all have moisture-inhibiting,Ventilating performance,The bottom surface of what bottom cultivating container is fixed by system by the hollow fixed cylinder bottom end system,The bottom surface of the upper layer cultivating container has an axis hole,The axis hole periphery is extended with locating plate,The axis hole of at least one or more upper layer cultivating container is arranged the hollow fixed cylinder outer surface of what by system,Keep locating plate and hollow fixed cylinder fixedly connected,Cause hollow fixed cylinder that can close the bottom surface axis hole of upper layer cultivating container,Cause above the cultivating container of upper layer cultivating container position what bottom,And form a multilayered structure； It is to put fertilizer or nutritional agents in the hollow fixed cylinder of what,And compost is put in what bottom cultivating container and upper layer cultivating container,The area Zhi Zai is formed,When water injects hollow fixed cylinder,The intracorporal fertilizer of the hollow fixed column or nutritional agents can be diluted with water penetration into the area Zhi Zai,To reach the double effects of irrigation and fertilising.一種多層植栽裝置，係包含一上層栽培容器、底部栽培容器及一中空固定柱體，該上層栽培容器、底部栽培容器及一中空固定柱體皆具有透濕、透氣特性，係將該中空固定柱體底端係固定於底部栽培容器的底面，該上層栽培容器的底面具有一軸孔，該軸孔周緣延伸有定位片，係將至少一個或一個以上之上層栽培容器之軸孔套設於中空固定柱體外表面，使定位片與中空固定柱體固定連結，致使中空固定柱體會將上層栽培容器的底面軸孔封閉，導致上層栽培容器位於底部栽培容器上方，而形成一多層結構；係於中空固定柱體內擺放肥料或營養劑，並於底部栽培容器及上層栽培容器中置放培養土，形成植栽區，當水注入中空固定柱體時，該中空固定柱體內的肥料或營養劑即會被稀釋跟水滲透至該植栽區中，以達到灌溉與施肥的雙重效果。
