A planting device, which is suitable of being installed under an anti-theft sun-shading rainwater-shading canopy, comprises a container, a rainwater irrigation unit, a tap water irrigation unit, an artificial irrigation unit and a water-absorbing unit. To attain the expected purposes, the container is configured with a bottom wall, a peripheral wall, an inner pipe wall having a top edge, a partition wall outwardly extended from the top edge of the inner pipe wall toward the peripheral wall, and a water-storing chamber defined jointly by the bottom wall, the peripheral wall, the inner pipe wall and the partition wall. Soil is filled in the inner pipe wall and on the partition wall. The rainwater irrigation unit comprises a rainwater pipe. The artificial irrigation unit comprises an artificial water-adding pipe and at least one water permeation hole, in which the artificial water-adding pipe is arranged in the soil of the container and penetrated through an artificial water-adding pipe that is communicated between the partition wall and the water-storing chamber. The water-absorbing unit comprises a water-absorbing end arranged in the water-storing chamber, a top end located in the soil, and a water-absorbing body connected to the water-absorbing end and the top end.一種適用於安裝在一防盜遮陽遮雨棚下的植栽裝置包含一容器、一雨水灌溉單元、一自來水灌溉單元、一人工灌溉單元及一吸水單元,確實達成本發明的目的,容器包括一底壁、一周壁、一內管壁、一自內管壁頂緣向外延伸至周壁的分隔壁,及一由底壁、周壁、內管壁與分隔壁共同界定的儲水腔,土壤填充於內管壁中與分隔壁上,雨水灌溉單元包括一雨水管,人工灌溉單元包括一設置於容器的土壤中且穿過分隔壁與儲水腔連通的人工加水管及至少一透水孔,吸水單元包括一設置於儲水腔的吸水端、一於土壤中的頂端及一連接吸水端及頂端的吸水體。1‧‧‧容器11‧‧‧底壁12‧‧‧周壁13‧‧‧內管壁14‧‧‧分隔壁15‧‧‧儲水腔16‧‧‧透水孔17‧‧‧水位計18‧‧‧排水孔2‧‧‧雨水灌溉單元21‧‧‧銜接管22‧‧‧雨水管23‧‧‧雨水儲水桶24‧‧‧活性碳濾芯25‧‧‧樞接桿26‧‧‧浮球3‧‧‧自來水灌溉單元31‧‧‧自來水管32‧‧‧樞接桿33‧‧‧浮球34‧‧‧直立桿35‧‧‧矽橡膠止水浮球4‧‧‧人工灌溉單元41‧‧‧人工加水管42‧‧‧透水孔43‧‧‧流道5‧‧‧吸水單元51‧‧‧吸水端52‧‧‧頂端53‧‧‧吸水體54‧‧‧玻纖吸水棉支架6‧‧‧照明單元61‧‧‧太陽能板62‧‧‧電池63‧‧‧植物燈A‧‧‧土壤100‧‧‧防盜遮陽遮雨棚
