The invention relates to air quality monitoring technical field, the present invention provides a portable experiment device for analysis of particle wet deposition ability of a plant, the portable experiment device comprises a plurality of collecting barrels and water storage tanks, the water storage tanks are in one-to-one correspondence connection with the collecting barrels; the top parts of the collecting barrels are provided with water inlets, the bottom parts of the collecting barrels are provided with water outlets, a coarse filtration device, a fine filtering device and a plurality of layers of filtration membranes are in turn arranged in the collecting barrel, the pore diameter of the filter hole of the plurality of layers of filtration membranes are in turn decreased; and the water storage tanks are in connection with the water outlets. The portable experiment device for analysis of particle wet deposition ability of the plant is convenient to disassembly and move, classification analysis can be directly performed within a forest without the need of experiment in a lab, and the problem of simultaneous accurate measurement of wet deposition effects of different plants in different forest types during snows and rains can be solved.
