A plant cultivation device comprises at least a container body. Each container body is provided with a strip-shaped bottom plate, and a plurality of equally-spaced partition boards are provided on the bottom plate, so that a plurality of separated cells are formed on the bottom plate. One side of the bottom plate is provided with a back plate which is utilized to connect each partition board, and the back plate is provided with a plurality of windows which are respectively communicated with the cells. Further, the bottom plate is provided with a plurality of first through holes which are respectively communicated with the cells. Thus, each cell of the container body can be acted as a growth space for receiving a plant, and the first through hole formed on the bottom plate is used as a channel for allowing plant root to contact with a nutrient solution located below the container body. Especially, under the action of the windows of the container body, the growth space of each plant is allowed to get a better air convection effect, thus to avoid plant decay caused by excessive humidity in the growth space in a relatively more active and reliable means and even to promote the growth effect of plant.本發明之植物栽培裝置,係具有至少一容器本體;其中,各容器本體係設有一長條狀的底板,於底板上設有複數等距排列的隔板,使於底板上區隔出複數格位,於底板其中一側設有一連接於各隔板之間的背板,於背板上設有複數分別與各格位相通的窗口;以及,於底板上設有複數分別與各格位相通的第一通孔。俾可利用容器本體之每個格位做為收容植物的生長空間,以及利用底板上的第一通孔做為植物根部與容器本體下方之養液接觸的通道;尤其,可在容器本體之窗口作用下,讓每一個植物之生長空間皆可獲致較佳的空氣對流效果,以相對更為積極、可靠之手段,避免因為生長空間過於潮濕而導致植物腐爛,更可藉以提升植物之生長品質。10‧‧‧植物20‧‧‧介質30‧‧‧容器本體32‧‧‧隔板321‧‧‧弧形導角322‧‧‧斜切面33‧‧‧格位34‧‧‧背板35‧‧‧窗口40‧‧‧底盤41‧‧‧凸肋42‧‧‧槽位50‧‧‧介質承架51‧‧‧容器單體
