A kind of potting plant material compression set solves the problems, such as inconvenience on known potting plant material extrusion operation with what. This creation includes: one first extrusion and one second extrusion, and along a direction of extrusion opposing compression or to back out, and second extrusion is equipped with perforating port that one opens up along the direction of extrusion and one is connected to the posting port of the perforating port； One third extrusion sets what second extrusion, and the corresponding posting port with group； Thereby, it can achieve the purpose that preferable plant material squeezing effect under the premise of not damaging plant cultivation and basin body is allowed to separate with the first extrusion or the second extrusion, to change the purposes of basin for potting.一種盆栽植材壓縮裝置，用於解決習知盆栽植材擠壓操作上不便之問題。本創作包含：一第一擠壓件及一第二擠壓件，用以沿一擠壓方向相對擠壓或退開，而該第二擠壓件上設有一沿該擠壓方向開設之穿置口及一連通該穿置口之置入口；一第三擠壓件，以組設於該第二擠壓件，並對應該置入口；藉此，能夠在不損傷植栽的前提下，達到較佳植材擠壓效果且讓盆體與第一擠壓件或第二擠壓件分離的目的，以為盆栽換盆之用途。
