The invention belongs to the technical field of contaminated soil remediation, and particularly relates to a halogenated hydrocarbon reductive dehalogenation repair slow-release complex microbial inoculant and a preparation method thereof. The complex microbial inoculant is mainly composed of a dehalogenation bacterium solution, edible vegetable oil and a surfactant, a large number of bubbles areprepared from the edible vegetable oil and the surfactant, and then the dehalogenation bacterium solution is added to enable dehalogenation bacteria to be wrapped by the bubbles. The formed bubbles not only can wrap and protect the dehalogenation bacteria, but also can promote the diffusion of the complex microbial inoculant in the horizontal direction; the edible vegetable oil provides an electron donor, a carbon source and nutrient substances to promote the growth of the dehalogenation bacteria; and the surfactant can emulsify and solubilize the vegetable oil and hydrophobic organic pollutants, improves the bioavail
