The seedling medium of this creation includes a substrate and a seedling space. The substrate is hollow and cylindrical, and the seedling space is surrounded and formed in the substrate.The created seedling medium has the function of convenient basin changing and selling, and can improve the quality of cultivated plants. It can omit the steps that traditional plants need to press the seedling medium into the cultivation basin when changing basins, reduce the problem of uneven cultivation quality caused by human operation, greatly reduce the cost of manpower and time, and improve the survival rate of plants. It can be managed with automatic equipment or Production, reduce labor cost and improve efficiency.本創作的育苗介質包括一基質體和一育苗空間，該基質體呈空心圓柱狀，該育苗空間環繞形成於該基質體中。本創作的育苗介質具有方便換盆與販賣的功效，並可提升培育植物的品質，可省略傳統植物換盆時需將育苗介質壓入培養盆中的步驟，降低人為操作造成培育品質不均一的問題，大幅減少了人力和時間成本，並提升了植株的存活率，並可配合自動化設備進行管理或生產，降低人力成本提升效益。
