Description

  The present invention provides a root storage chamber into which a culture solution is supplied and discharged inside a box made of a heat insulating material, the leaf stem portion of the plant planted on the upper plate of the box on the top surface of the box, and the root in the above-mentioned root storage Plants grown in a plant cultivation box or a panel floated on the surface of the culture solution, and the leaves and stems of the plant extended from the bottom of the panel and the roots extended from the bottom of the panel into the culture solution. The present invention relates to a reversing device for other various types of plant cultivation bodies such as cultivation panels.

  The present inventor previously turned the panel upside down 180 degrees on the immersion liquid as a method for controlling the pests adhering to the leaf stem portion of the plant in the plant hydroponics using the plant cultivation panel. By immersing the plant leaf stem part in the immersion liquid for a long time and suffocating and killing the pest, and the above cultivation panel is turned upside down 180 degrees, and the plant leaf stem part is immersed in the immersion liquid for a short time and leaves the pest. A method to detach from the stem was proposed.

  In order to carry out the above proposed method, the present inventor further, as a device for inverting the plant cultivation box, a plurality of cultivation boxes are juxtaposed in the front and rear adjacent state, and the shafts projecting on the left and right sides facing each cultivation box Each box is supported rotatably, and a sprocket is fixed to the axis of each box, and an endless chain is hung on each sprocket of each box adjacent to each other, so that each cultivation box is simultaneously connected via each chain. A chain-type reversing device was proposed which can be rotated in the same direction.

  However, the conventional chain-type reversing device has a risk that when the cultivation boxes are reversed at the same time, the plant leaf stems protruding from the upper surface of each box may collide with the adjacent box. There is an inconvenience limited to short ones, and the method of planting has to be planted in one horizontal row, resulting in a disadvantage that the yield is reduced.
