The present invention relates to the technical field of plant cultivation, and specifically relates to a bottom water supply irrigation bed and a cultivation apparatus comprising said irrigation bed. The irrigation bed comprises a bottom part, side walls surrounding the periphery of the bottom part, and a water inlet and a water outlet, the upper surface of the bottom part being provided with a plurality of support structures, and the top parts of at least some of the plurality of support structures being on the same horizontal plane. The irrigation bed and the cultivation apparatus using said irrigation bed provided in the present invention target the problem of water accumulation caused by incomplete drainage and the problems of roots growing out of cultivation containers and uneven growth of seedlings as a result of same, reducing the local water accumulation caused by surface tension by means of reducing the contact area between the cultivation container and the irrigation bed surface, and achieving a good root control effect.
