The present invention easily assembled construction have a size different bath tailored to simple cultivation scale, respectively, to provide a plant cultivating tub which is excellent in durability. A a rectangular bottom plate 2A, and a corner wall 2B erected on the two opposite edge side of the bottom plate, an end wall provided upright on one side edge of the bottom plate adjacent to these corner walls provided, the other end two ends of the joint 2D is formed at the edge unit 2 of the bottom plate, the junction piece is deposited on the junction side surface each other and the joining lower surface side each other adjacent to the end unit with 4, abut the two ends unit is opposed junctions each other, joined portions together of the units that are adjacent to each other are applied to the joint portion side surface and these bonding the lower surface side of the adhesive bond The result is integrated by the strip, it is characterized in that a drainage port is formed in a portion of one of the end unit. .BACKGROUND 2【課題】施工が簡単で栽培規模に合わせた大きさの異なる槽をそれぞれ組み立て易く、耐久性に優れた植物栽培槽を提供する。【解決手段】矩形状の底板2Aと、底板の対向する2つの端縁側に立設されたコーナー壁2Bと、これらコーナー壁に隣接する底板の一側端縁に立設された端部壁を備え、底板の他側端縁に接合部2Dが形成されてなる2つの端部ユニット2と、隣接された端部ユニットの接合部下面側どうしと接合部側面側どうしに被着される接合片4を備え、2つの端部ユニットが接合部どうしを対向させて突き合わされ、相互に隣接されたユニットの接合部どうしがこれらの接合部下面側と接合部側面側に被着し接着された接合片により一体化されてなり、一方の端部ユニットの一部に排水口が形成されたことを特徴とする。【選択図】図2
