The utility model discloses a sampling device for rapidly detecting verticillium dahliae microsclerotia in soil, which comprises an air compressor, a pressure gauge and a microorganism sampler, and a gas inlet of the air compressor is connected with an exhaust port of the microorganism sampler through a pipeline. And the pressure gauge is arranged on a pipeline for connecting the air compressor and the microorganism sampler. According to the utility model, the air compressor is started, the fine weighing spoon is used for weighing a soil sample, the weighed soil sample is quickly poured into the inlet at the top end of the microorganism sampler, the palm is propped against the inlet of the device, and the soil sample can be uniformly laid in the culture dish under the action of air extraction in the microorganism sampler; then culturing to form macroscopic bacterial colonies, counting the bacterial colonies, and calculating the individual concentration according to the sampling volume, so that the content of
