PROBLEM TO BE SOLVED: To provide a cultivation device constructed by closely arranging a plurality of hollow three-dimensional members set with an opening part (2) on the side face so as to supply a further large amount of air directly to the surroundings of roots, and let air freely flow in a culture medium, in view of the fact that conventionally, it is not easy for a cultivation container and a cultivation device using soil to take air into a culture medium because of the structure, and to increase air permeability requires air permeable materials or equipment and materials to take much labor and cost.SOLUTION: A cultivation device is constructed by bringing a plurality of hollow three-dimensional members (1), (1)... which have a square column form and whose at least upper end is opened, to an aggregate by mutually closely arranging side faces of at least one of each member (1), setting opening parts (2) connected to each other on at least each of the side faces adjacent to each other in a row, among each of the side faces of each of the members (1) forming the aggregate, and fastening the aggregate by fixtures.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来、用土を用いる栽培容器や栽培装置は構造上、培地に空気を取り込むのは容易でなく、通気性を高めるには通気材や機材を要して手間やコストがかかる。本発明はより多量に直接根周りに空気を供給し、且つ空気が培地内を自在に流れるように、側面に開口部(2)を設けた複数の中空立体部材を寄せ並べて成る栽培装置を提供する。【解決手段】角柱状を成し、少なくても上端が開口した複数の中空立体部材(1).(1)・・を、各部材(1)の少なくても一つの側面同士を相互に寄せ揃えた集合体にし、当集合体を構成する各部材(1)の各側面のうち、少なくても互いに隣り合って並ぶ側面同士の夫々に、互いに繋がりあう開口部(2)を設け、当集合体を固定具で固定したことを特徴とする。【選択図】図1
