The present invention relates to a seedling pot mounting device for a fixed seedling pot laid in a high-bed cultivation apparatus, which comprises: a pair of upper and lower lateral pipes (2, 2′) mounted and fixed in a lateral direction to a pole pipe (1) of the high-bed cultivation apparatus； a mount (3) mounted on the lateral pipes (2, 2′) by using a strap (6) while crossing the pipes (2, 2′)； and a pair of pot supporting rods (4, 4′) mounted on an upper portion of the mount (3), wherein the mount (3) is configured to fasten, to an upper end of a vertical pipe (3b) having a predetermined length, a U-shaped coupling portion (31) having an arc with a diameter which is the same as a diameter of an arc of the vertical pipe (3b) and a square hole (32) and a circular hole (32′) respectively formed in both side surfaces to face each other and a supporting frame (3a) formed with one end of the U-shaped coupling portion (31) longitudinally extending and having semi-circular supporting grooves (34, 34′) on which the pot supporting rods (4, 4′) for mounting a seedling pot (5) on front and rear portions of an upper surface is mounted and supported, using a shank bolt (3c) and a nut (3c′). Accordingly, the mount (3) can be forcibly transferred on the lateral pipes (2, 2′) in a lateral direction and folded by rotation, thereby maximizing convenience of installation and usage. At the same time, the device has a simple configuration, thereby being distributed at low costs to farmers, and thus, it is possible to maximize reliability such as greatly reducing the burden on the farmers.본 발명은 고설재배장치에 부설하는 제자리육묘를 위한 육묘포트 안착장치에 관한 것이다.구성에 있어서, 고설재배상의 지주관(1)에 횡방향으로 장착 고정시키는 상하 한 쌍의 횡파이프(2)(2')와, 조리개(6)를 이용하여 상기 횡파이프(2)(2')에 크로스 결착시키는 안착대(3), 상기 안착대(3)의 상부에 안착되는 한 쌍의 포트받침봉(4)(4')으로 구성하되, 상기 안착대(3)는 소정의 길이로 된 수직관(3b) 상단에, 상기 수직관(3b)의 원호와 같은 크기의 원호내경을 가지며 양 측면에 각각 사각공(32)과 원형공(32')이 대향 천공된 U형 결합부(31)와, 상기 U형 결합부(31)의 일단이 길게 연장되어 상면 전후부에 육묘포트(5)를 안착시키기 위한 포트받침봉(4)(4')을 안착 지지하는 반원형 받침홈(34)(
