The present invention relates to a bed soil distribution and supply device for a bed for high-altitude cultivation. The bed soil distribution and supply device for a bed for high-altitude cultivation, which is placed on the bed for bed soil placement, performs earth and sand filling and groundwork at the same time, and forms a ridge well, includes: a loading portion having an open upper portion where an insertion portion is formed for earth and sand (bed soil) insertion and storage, having slopes formed on respective side surface plates and having various types of structures in which upper portions are wide and lower portions are narrow, and having a discharge portion smaller in size than its upper portion formed in its lower portion, a vertical member preventing a deviation of earth and sand by coming into contact with an upper surface of the bed being included in an end portion of the discharge portion a pressing stop portion where a protruding entering member is formed on a front face of the loading portion and the earth and sand are compressed or subjected to groundwork for ridge formation on its back face a bed width adjustment unit horizontally connected to the other end of the lower portion of the loading portion such that the width of the bed varies and a wheel inserted into a plurality of shafts disposed in the entering member protruding from the front face of the loading portion.본 발명은 고소재배용 베드의 상토분배공급장치는 상토를 안치하는 베드의 상부에 안착되어 토사를 충전(充塡) 함과 동시에 정지, 두둑을 원활하게 형성하는 고소재배용 베드의 상토분배공급장치에 있어서,상부는 개방되어 토사(상토)를 인입 저장하는 인입부가 형성되고, 각형의 상광하협(上廣下陜)의 구조로 각 측면판에는 경사가 형성되어 있고, 하부에는 상부보다 크기가 적은 배출부가 형성되고, 상기 배출부의 단부에는 베드의 상면과 접촉하여 토사가 이탈되는 것을 방지하는 수직부재를 포함한 적재부와, 상기 적재부의 전면에는 돌출된 진입부재가 형성되고 그 후면에는 토사를 압착 내지 정지, 두둑을 형성하는 누름정지부와, 적재부의 하부 타단에는 수평으로 연접되어 베드의 폭을 가변하는 베드폭조정부와, 적재부의 전면에 돌출된 진입부재에 복수의 축을 부설하고 그 축에 끼워진 바퀴가 형성된 것을 특징으로 한다.
