1. A drawer-type plant cultivation apparatus, comprising:
a body unit having a hexahedral frame configured to be erected on a ground, the body unit having a plurality of support bar pairs symmetrically disposed on inner surfaces of both sides of the hexahedral frame to be vertically spaced apart from each other;
a plant unit having at least one plant box, each of the at least one plant box having both sides of a top end thereof being configured to be inserted into a front of the body unit to be seated on one of the plurality of support bar pairs on both sides, the at least one plant box being movable forward and rearward; and
at least one piping unit, each being disposed inside each of the at least one plant box,
wherein each of the at least one piping unit comprises:
a piping part connected to a rear of each of the at least one plant box to supply a nutrient solution and supply oxygen; and
one or more corrugated pipe parts connected to bent points of the piping part,
wherein, when the at least one plant box is moved forward, the at least one piping unit is configured to be moved forward of the body unit while being disposed in the at least one plant box while the one or more corrugated pipe parts are extended,
wherein, when the at least one plant box is moved rearward, the at least one piping unit is configured to be inserted into the body unit while being disposed in the at least one plant box while the one or more corrugated pipe parts are contracted,
wherein each of the at least one plant box is configured to be selectively installed onto any one of the plurality of support bar pairs according to a height of a plant to be planted in each of the at least one plant box, the at least one plant box having no restriction to installation space from a bottom of the body unit to a top of the body unit,
wherein each of the at least one plant box includes a plurality of through holes defined on a bottom portion of a rear side of each of the at least one plant box, and each of the at least one piping unit includes an oxygen module including a plurality of oxygen pipes,
wherein the plurality of oxygen pipes extends through the plurality of through holes, respectively, to be arranged in a bottom portion of a soil contained in each of the at least one plant box to supply oxygen uniformly to an overall area of the soil.
