Disclosed is a green forage continuous cultivation apparatus to continuously cultivate green forage used as feed for domestic animals, thereby enabling production of crops within a reduced time. In the green forage continuous cultivation apparatus, seed beds are moved along a guide in a curvilinear route by means of a curvilinear movement device within a main body, the seed beds a being immersed in a water supply unit while being moved along the curvilinear route, which enables periodic supply of water to the seed beds. Supplying water to the seed beds by moving the seed beds along a curvilinear route enables adjustment of the supply period of water by adjusting a movement speed of the seed bed. Also, it is possible to prevent leaves from rotting or growth of moss or bacteria on leaves due to water because water is directly supplied to roots rather than leaves.
