Problem to be solved: to provide a support structure of a fruit tree which is simple, inexpensive, and does not shake strongly and is suitable for the embankment type rhizosphere control cultivation method, and an extraction pipe for a Y-shaped finish for use.Solution: the support structure of the fruit tree consisting of the following members, suitable for orchards having a plurality of embankment rows (regions in which a plurality of embankments are linearly arranged at regular intervals) related to the embankment type troposphere control cultivation method, are at least supported by the above described members, and both ends of the vertical pipe 1 and both side pipes 2It is composed of both end guide pipes for y-letter completion, fixing pipes for longitudinal pipes, reinforcement support pipes, intermediate longitudinal pipes 6, intermediate transverse pipes, intermediate guide pipes for Y-shaped cutting, and wire rows 9, fixed base and vertical pipes 11. The wire 9 extends to the end of the orchard in the left and right direction, and the end portion is fixed to the support for the bird net for covering the whole orchard.Diagram【課題】盛土式根圏制御栽培法に適した、簡便かつ安価で風にも強く揺れない果樹の支持構造及びこれに用いるY字仕立用誘引パイプの提供。【解決手段】盛土式根圏制御栽培法に係る複数の盛土列(一定間隔で直線的に複数の盛土を配置した領域)を有する果樹園に適した、少なくとも下記の部材からなる果樹の支持構造であり、両端縦パイプ1、両端横パイプ2,Y字仕立用両端誘引パイプ、縦パイプ同士の固定用パイプ、補強用支持パイプ、中間縦パイプ6、中間横パイプ、Y字仕立用中間誘引パイプ、ワイヤ9、固定ベース、縦パイプ同士の間に設けた盛土列11から構成されている。ワイヤ9は左右方向に果樹園の端まで伸びており、その端部は果樹園全体を覆う防鳥ネット用支柱に固定されている。【選択図】図1
