A plant cultivation device is provided, including a cultivation frame body (10), a plurality of hydroponic bases (20), a soil cultivation base (30), a plurality of filter bases (40), a water storage base (50) and a plurality of lights (60), the cultivation frame body having a frame (11), wo sides of a top surface of the frame of the cultivation frame body each having a front rod (12) and an rear rod (13), a plurality of hold bases being disposed between and on the front rods, the plurality of hold bases (121) respectively having three layer hydroponic bases, each of which is hollow and has a plurality of cultivation holes (201), each of the hold bases corresponding to one of the lights, the soil cultivation base, the soil cultivation base having a bell syphon with a drain tube (81) disposed thereinside, the water storage base having a submersible pump (100) and an external inlet tube (70).本創作係提供一種植耕設備改良，其主要是於一植耕架體的上半部以一定間隔架設有一個以上的中空且設有複數個栽植孔之水耕座(可以是水管型也可以是層架式水槽型的水耕座)，而於下半部則以疊置方式由上而下設有一土耕座及一個以上之過濾座與一個蓄水座，於蓄水座設有沉水馬達，並外接一進水管導接至最上方之第一層水耕座之左端(或右端)，而於第一層水耕座的右端(或左端)設導流管導接至下一層的第二層水耕座右端(或左端)，而於第二層水耕座的左端(或右端)設導流管導接至下一層的第三層水耕座左端(或右端)，而於第三層水耕座的右端(或左端)設出水管導流至土耕座上，另外於每一層水耕座及土耕座上方皆設有一或複數個照明燈管，於每一層水耕座的栽植孔上皆置入植栽物，而於土耕座內填置有培養土(或植栽土或介質土或組合的多層石礫層)並置入植栽物，且於土耕座內設有一虹吸鐘，藉此設置，利用沉水馬達將水由蓄水座抽送至第一層水耕座內，經導流管再流過第二層、第三層後，由出水管排至土耕座內，而由虹吸鐘將土耕座內過多的水排放至過濾座經過濾後流入蓄水座內，藉由此循環水流以供水耕植栽物與土耕植栽物吸收水份並帶動養劑的均勻混合和流動，得讓栽植的蔬果達到最佳的品質，由於此架構同時得以進行水耕及土耕，這也提升了整體的實用性。
