Abstract
A sub-irrigation bed includes a bottom, a side wall surrounding the bottom, a water inlet, and a water outlet. A plurality of support structures is arranged on an upper surface of the bottom, and tops of at least a part of the plurality of support structures lie in the same horizontal plane. By reducing the contact area between the cultivation container and the surface of the sub-irrigation bed to reduce local water accumulation caused by surface tension, the sub-irrigation bed and the cultivation apparatus using the sub-irrigation bed provided by the present invention solve the problem of water accumulation caused by incomplete drainage and the resulting problems that roots grow out of the cultivation container and seedlings grow irregularly, thereby achieving a good root control effect.
