Plant cultivation system

A plant cultivation system for cultivating a plant, the plant cultivation system comprising:

• a transporting conveyor which transports a container, where the plant is planted, along a transport pathway;
• and
• an irrigation device which is located in an irrigation area on the transport pathway, and supplies liquid to the plant planted in the container,
• wherein the irrigation device includes:
• a nozzle which discharges, from above, the liquid to the container located in the irrigation area;
• a cover which has a box shape with a bottom end portion open, and prevents the liquid discharged from the nozzle from splattering around the container;
• and
• a moving mechanism which moves the cover between a first position and a second position,
• the bottom end portion of the cover has a receiving recessed portion extending from the bottom end portion of the cover toward an inside of the cover, for receiving the liquid from the nozzle flowing down an inner surface of the cover, and
• the nozzle extends through a top surface of the cover,
• wherein (i) when moved to the first position, the cover covers space above the container located in the irrigation area, and (ii) when moved to the second position, the cover is removed from the space above the container located in the irrigation area and the space is uncovered, and
• the moving mechanism moves the cover (i) to the first position when the liquid is supplied to the plant, and (ii) to the second position when the supplying of the liquid to the plant ends.
