摘要

PROBLEM TO BE SOLVED: To provide a support structure for a plant growing layer, which can more efficiently and easily form a support structure for a plant growing layer, which has a loaded weight reduced as much as possible; a material for forming the support structure for the plant growing layer; and a base.SOLUTION: Bases S are provided on each of hill portions F3 of a folded-plate roof F. A wire net N is supported on the base, and a wire N1 in a crosswise direction and a wire N2 in a lengthwise direction decide a position of the wire net N with respect to each of the bases S so that the wire net N and the bases S have a relationship in a predetermined horizontal location. A mat for forming the plant growing layer is supported on the wire net N supported on the bases S.
