The invention provides a micro-fluidic chip and a microbiological detection method, the micro-fluidic chip comprises a chip body, the chip body is provided with a mixing module, the mixing module comprises a first gas pumping structure, and a mixing pneumatic valve, a mixing one-way valve, a liquid mixing valve and a mixing channel which are connected in sequence; the first gas pumping structure is used for controlling the mixing pneumatic valve and the liquid mixing valve to be switched between an opening state and a closing state; the mixing pneumatic valve is used for controlling whether the mixing one-way valve communicates with the liquid conveying channel; the liquid mixing valve is used for storing liquid or gas when in an open state, and the liquid or gas is squeezed into the mixing channel when the liquid mixing valve is in a closed state. The device further comprises a pumping module which is used for pumping liquid to the mixing module and is similar to the mixing module in structure and principle,
