A plant cultivation apparatus is provided to enable stable high-yield cultivation of crops and promotes balanced growth of the underground part and aerial part of crops by preventing root browning and thickening caused by oxygen deficiency during hydroponic cultivation. A plant cultivation apparatus(1) comprises: an auxiliary cultivation panel(10) with a planting hole(12) to insert a germination support body of sowing-seed and to plant seedlings to be cultivated; a cultivation panel(20) with a mounting jaw(22) at the inside surface to mount the cultivation panel and a net(24) to support root of crops passed through the planting hole; a cultivation tank(30) for storing a nutrient solution to supply to crops; a height adjusting device(100) for controlling the level of the nutrient solution and the height of crops; and a power source control device(70) for automatically ascending and descending of crops by applying an electric current. The cultivation tank has a nutrient solution supply device(40) with a nutrient solution supply pipe(42) to automatically supply a nutrient solution. The nutrient solution supply pipe has an air Venturi device(60). |
