Clamping device applicable to plant layering

The invention discloses a clamping device applicable to plant layering. The clamping device comprises a port clamping device, a bag body clamping device and a force applying clamping body which are integrally arranged, wherein the port clamping device can be used for clamping the fastening end of a layering bag tightly; the bag body clamping device can be used for clamping a layering bag body tightly; and the force applying clamping body is linked with the port clamping device and a bag body clamping device. The clamping device disclosed by the invention is high in clamping degree, and can effectively ensure that the layering bag is difficult in falling under the influence of external environment, is wide in application range, and can be applicable to multiple layering modes such as air layering, common layering, horizontal layering, earth-mounding layering and wave-shaped layering, and has the advantages of simple structure, easy implementation, lower cost and long service life.
