PROBLEM TO BE SOLVED: To provide an air purifying and greening apparatus which is easy to resize, has good handling and workability, is difficult to cause the bias of a plant growth base, and can constantly keep the environment of plant growth in each portion of the plant growth base.SOLUTION: An air purifying and greening apparatus 1A has a plurality of planting units 2 arranged in a line. The planting unit 2 has a plant growth base 6 having a front side which is a planting surface in which a plant P is planted, a ventilation layer 7 which is a partition space adjacent to the back side of the plant growth base 6, and a fan 8 positioned in the back side of the ventilation layer 7 and sending air into the plant growth base 6. A plurality of the planting units 2 adjacent to each other are detachably connected by connecting means.SELECTED DRAWING: Figure 1【課題】サイズ変更が容易で、取扱い性および施工性が良く、植物生育基盤の偏りが生じ難く、植物生育基盤の各部で植物生育環境を一定に保つことができる空気浄化緑化装置を提供する。【解決手段】空気浄化緑化装置1Aは、複数の植栽ユニット2が並んで配置されている。植栽ユニット2は、正面側が植物Pの植えられる植栽面である植物生育基盤6と、この植物生育基盤6の背面側に隣接した仕切り空間となる通気層7と、この通気層7の背面側に位置して植物生育基盤6に通気するファン8とを有する。複数の植栽ユニット2は互いに隣合うもの同士が連結手段によって着脱可能に連結される。【選択図】図1
