PROBLEM TO BE SOLVED: To provide a cultivation bed and a cultivation device capable of widely distributing roots of crops in capillary hydroponics.SOLUTION: The cultivation bed is used in capillary hydroponics and comprises a culture medium part that allows crops to adhere, a root shielding water permeable sheet provided at the bottom part, and a laminate part provided between the culture medium part and the root shielding water permeable sheet. The laminate part has a weak root shielding water permeable layer that has weaker root shielding properties than the root shielding water permeable sheet, and a low water pumping layer laminated on the bottom part side of the weak root shielding water permeable layer and that has lower water pumping power than the weak root shielding water permeable layer.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】毛管水耕栽培において作物の根を広く分布させることができる栽培床及び栽培装置を提供する。【解決手段】本発明の一態様に係る栽培床は、毛管水耕栽培に用いられる栽培床であって、作物を着生させる培地部と、底部に配設される遮根透水シートと、上記培地部及び上記遮根透水シート間に配設される積層部とを備え、上記積層部が、上記遮根透水シートより遮根性が弱い弱遮根透水層と、上記弱遮根透水層の底部側に積層され、上記弱遮根透水層より揚水力が低い低揚水層とを有する。【選択図】図1
