Ethylene release amount detection device for cut chrysanthemum

The invention provides an ethylene release amount detection device for cut chrysanthemum. The polyimide base material and the gas sensitive layer attached to the surface of the polyimide base material are directly adhered to the surface of the to-be-detected position through the silica gel supporting structure, a heat insulation gap can be provided through the silica gel supporting structure, and the heating layer on the back side of the gas sensitive layer is prevented from damaging the surface of the to-be-detected position in the detection process. The silica gel supporting structure has viscidity and can be firmly and directly adhered to the surface of a detected object, glue is not needed, and the detected object is not damaged. In addition, the silica gel supporting structure has a certain thickness, so that the structure is more stable, adhesion failure caused by the influence of the elasticity of the material is avoided, and the detection work of the electrode structure can be continuously and stably
