1. A plant cultivation apparatus comprising:
- a guide rail disposed above a cultivation bed and extending along the length direction of the cultivation bed;
a movable unit coupled to the guide rail and configured to move along the guide rail;
an arm unit comprising a first end that is coupled to the movable unit, and a second end that is extendable from the movable unit toward the cultivation bed;
an ultraviolet (UV) radiation unit coupled to the second end of the arm unit and configured to irradiate the cultivation bed with a set amount of UV light;
a sensor configured to measure a distance between the UV radiation unit and the cultivation bed; and
a control unit configured to control a length of the arm unit according to distance information included in an output signal of the sensor, and to control a speed at which the movable unit moves along the guide rail such that the entire cultivation bed is irradiated with substantially the same amount of UV light.

5. A plant cultivation apparatus comprising:
-
a shelf; a frame configured to support the shelf; an ultraviolet (UV) radiation unit disposed on the frame above the shelf and configured to irradiate plant material disposed on the shelf with UV light for period of time before the plant material is processed, the UV radiation unit comprising an ultraviolet light emitting diode (UV-LED) module comprising a first LED that emits UV-A light and a second LED that emits UV-B light or UV-C light; a moveable unit disposed on the frame and configured to move the UV irradiation unit with respect to the shelf; and a control unit configured to control the moveable unit and the UV radiation unit, such that the plant material is irradiated with an amount of UV light sufficient to increase the content of ginsenosides in the plant material, wherein the plant material comprises harvested ginseng. - View Dependent Claims (6, 7)
