BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high grade cultivation apparatus capable of selective partial opening and closing, and more particularly, to a supporting apparatus 100 arranged in two rows in a vertical direction from a ground, A support frame 200 formed on each support 100； A plurality of ports (300) seated on the support frame (200) and configured for strawberry seedlings； And a slide groove 220 is formed on both sides of the upper portion of the support frame 200. The slide groove 220 is formed at an upper portion of the support frame 200, Each of the thermal insulation tunnels 400 is formed to be able to move along the support frame 200 and covers the upper part of each of the thermal insulation tunnels 400, A blocking plate 210 is formed on both sides of the upper portion of the support frame 200 to selectively open and close the inside of the house. The barrier plate (210) is formed to extend higher than the upper side of the support frame (200), and is formed to correspond to the inside of the thermal insulation tunnel (400) The inside of the heat insulating tunnel 400 located at the rear side And water is supplied to the port 300. When the water is supplied to the port 300, the water is supplied to the lower part of the support frame 200, And is connected to the blocking plate 210 by a nozzle so that chlorine dioxide is introduced into the inside of the thermal insulation tunnel 400. In addition, (600), thereby maintaining the original purpose of the strawberry cultivation apparatus and at the same time maximizing the effect of thermal insulation by completely sealing the strawberry seedlings through the selectively openable and closable thermal tunnel and clogging plate And it is possible to selectively flow the thermal insulating tunnel, so that it is possible to control the ventilation and the thermal insulation according to need, thereby providing convenience of use, To inhibit bacteria by feeding
