The invention provides a method for preparing marsh gas through fermentation of traditional Chinese medicine residue. The method specifically comprises the steps of pretreatment of the traditional Chinese medicine residue, precise treatment of the traditional Chinese medicine residue, domestication and mixing of inocula, inoculating, fermentation and the like, wherein during the precise treatmentof the traditional Chinese medicine residue, urea is adopted as the nitrogen source for regulating the carbon-nitrogen ratio, and an ammonium hydroxide-ammonium chloride buffer solution is adopted foradjusting the pH; the inoculum 1 is formed by mixing of biogas slurry, fresh pig manure and traditional Chinese medicine residue at the mass ratio of 6 to 3 to 1 and domestication, and the inoculum 2is formed by mixing of anaerobic sludge from a sewage treatment plant and the traditional Chinese medicine residue at the mass ratio of 9 to 1 and domestication. With the method provided by the invention, the technical problem
