The flexible isolation layer is fixed in the sealing groove by the extrusion strip, which facilitates the removal of the flexible isolation layer and can be repeatedly used.

[0013] The technical solution of the utility model also includes: the flexible isolation layer is connected to the inner wall of the containing box by means of a sealant.

[0014] The technical solution of the utility model also includes: the flexible isolation layer comprises a nylon net or a plastic film.

[0015] The technical solution of the utility model also includes: the rotating bracket is provided with a rotating groove opening upward, and the rotating shaft is arranged in the rotating groove. By providing the rotating groove opening upward on the rotating bracket, it is convenient to take and place the rotating shaft, and it is convenient to quickly replace the flexible isolation layer.

[0024] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, a potted plant device for studying the interaction between the roots of intercropped plants comprises a containing box 1, a rotating bracket 2, a rotating shaft 3 and a flexible isolation layer 4, wherein the containing box 1 opens upward, a rotating bracket 2 is arranged at a middle position above the containing box 1, and the rotating shaft 3 is rotatably mounted on the rotating bracket 2 along the width direction of the containing box 1; the rotating bracket 2 is provided with a rotating groove 21 opening upward, and the rotating shaft 3 is arranged in the rotating groove 21.

[0027] The upper end of the flexible isolation layer 4 is wound around the rotating shaft 3 , and the flexible isolation layer 4 is sealed and connected to the inner wall of the containing box 1 , thereby dividing the inner cavity of the containing box 1 into two planting areas.

[0028] The bottom of the storage box 1 is opened, and a detachable bottom plate 5 is provided at the bottom of the storage box 1 .

[0029] The bottom of the receiving box 1 is provided with a sliding key 11 along the length direction, and the bottom plate 5 is provided with a sliding groove 51 matching the sliding key 11 . The bottom plate 5 is slidably arranged at the bottom of the receiving box 1 .
