The present invention provides a green wall planting tank for placing a plurality of planting and filtering materials, which has a front plate, a back plate, a bottom plate and two side plates, wherein the front plate is inclined outward. And the bottom plate is provided with a plurality of first drainage holes and a plurality of top columns, wherein the first drainage holes are provided for filtering out excess water, and the top columns are configured to clamp the filter materials and lift them upwards. It is avoided that the filter materials are too close to the bottom plate to affect the drainage effect of the first drainage holes. The creation uses the front panel which is inclined to increase the exposed area of the plant to enhance the appearance. The top pillars prevent the first drainage holes from being blocked, and prevent the occurrence of water accumulation and affect the growth of plants and the growth of bacteria.本創作提供一種綠牆植栽槽體，供以放置複數個植栽與濾材，其具有一前板、一背板、一底板與二側板，其特徵在於，該前板係呈向外傾斜狀，且該底板設有複數個第一排水孔及複數個頂柱，該等第一排水孔係供以濾除多餘水分，該等頂柱供以卡固該等濾材並將其向上頂抵，避免該等濾材過於緊貼該底板而影響該等第一排水孔之排水效果。本創作利用傾斜設置之該前板，係可增加植栽的顯露面積以增進美觀性，該等頂柱則可防止該等第一排水孔堵塞，避免產生積水現象而影響植物生長及孳生細菌。
