The invention discloses a real-time on-line monitoring device for multiple gases of farmland. The device includes a superluminescent diode, a diode controller, a function generator, a spectrometer, an off-axis quartz tuning fork enhanced photoacoustic cell, a power meter, an adder, a lock-in amplifier, a data acquisition card, and a notebook computer. The modulated light emitted by the superluminescent diode undergoes beam splitting by a beam splitter, then one part of the light enters the spectrometer through lens gathering, and the other part of light enters the off-axis quartz tuning fork enhanced photoacoustic cell through lens gathering. Gases in the photoacoustic cell absorbs energy, and thermal energy is generated by nonradiative transition, so that the gases can expand and shrink, and resonant sound waves generated in a tubular resonant cavity are detected by the quartz tuning forks. The quartz tuning forks convert the detected sound signals into electrical signals. The two electrical signals are respectively amplified by pre-amplifiers, added together by the adder, and then transmitted to the lock-in amplifier to carry out demodulation. The demodulated signals are acquired by the data acquisition card, and after analysis, concentrations of the gas can be obtained.
