This creation system provides a kind of natural ecology soil horizon cultivating pot,Espespecially a kind of closed cultivating pot,The cultivating pot is that a bottom is in closed container,The what container bottom is laid with one layer of cobble as reservoir bed,It is the wall for preventing soil sagging that pebble masonry is laid on cobble,It is then covered with above small gravel and plants cultivation soil composition soil horizon,It is separately embedded with the gas-guide tube of at least one through container bottom,Imitative natural ecology soil horizon is built up according to this,Using the framework of natural ecology soil horizon,When it being made to pour water the plant of container plantation,Reach saturation state Hou when soil horizon absorbs water,Remaining excessive moisture content is the reservoir bed storage for flowing into cobble through soil horizon and constituting,When soil water shortage,The moisture content for storing what reservoir bed is returning to soil through wall by osmosis,It is absorbed in order to obtaining for plant,Natural soils ecological recycle system is established according to this,Not easily runed off up to moisture content,Need not often water,Free from environmental pollution,Without below potting placement tray,Not raw mosquito,The usable environmental protection effect person of any old container.本創作係提供一種自然生態土壤層植栽盆，尤指一種封閉式植栽盆，該植栽盆為一底部呈封閉式之容器，於容器最底層鋪設一層卵石作為儲水層，卵石上鋪設小礫石作為防止土壤下陷之間隔層，小礫石上方再鋪上植栽用土壤構成土壤層，另埋設有至少一條直達容器底部之導氣管，依此建構出仿自然生態土壤層，利用自然生態土壤層的架構，使其對容器種植的植株灌水時，當土壤層吸水達到飽和狀態後，剩餘過多的水份乃經土壤層流入卵石構成的儲水層儲存，當土壤缺水時，儲存於儲水層的水份乃藉滲透作用而經間隔層回到土壤，俾得供植株吸收，依此建立自然土壤生態循環系統，達水份不易流失、不必經常澆水、不污染環境、不用在盆栽下方放置托盤、不生蚊蟲、任何舊容器均可使用之環保功效者。
