The invention relates to the technical field of soil remediation, and provides a halohydrocarbon degradation microorganism composite remediation material and a preparation and application method thereof. The preparation method of the material comprises the following steps: adding the solid magnetic iron-based biochar into a dehalogenation microbial fermentation culture medium, then inoculating a dehalogenation microbial seed solution, fermenting, and taking out a fermentation liquid suspension mixed with the solid magnetic iron-based biochar after the fermentation is finished, so as to obtain the halohydrocarbon degradation microbial composite repair material. According to the method, the solid magnetic iron-based biochar and the dehalogenation microorganisms are co-fermented, so that the synergistic effect among the biomass charcoal, the nano zero-valent iron and the dehalogenation microorganisms can be improved to the maximum extent, and the halogenated hydrocarbon microorganism composite repair material wi
