The invention discloses an integrated multi-parameter test platform for microbes. The integrated multi-parameter test platform is mainly applied to the qualitative and quantitative detection on the microbes in a liquid. The test platform comprises a high-accuracy plunger type trace sampling pump, a microfluidic chip, a microscopic lens, a microscopic high spectrometer, a computer, a fiber spectrometer and a dielectric spectrometer, wherein the high-accuracy plunger type trace sampling pump can be used for accurately controlling the sampling of a microbial test solution. According to the platform, information acquisition of microscopic images of the microbes in the liquid can be realized, meanwhile, spectral characteristic information and dielectric property information on the microbes can be acquired, and the synchronous acquisition of multivariate information on the microbes is realized, so that the synchronous acquisition of the multivariate information on the microbes is realized, the efficiency of detection is increased, and the accuracy of detection is improved.
