The invention discloses a preparation method of a composite microbial organic fertilizer based on an attapulgite-modified material, and belongs to the technical field of microbial organic fertilizers.The preparation method adopts a fermentation method of adding fermenting bacteria and functional bacteria in a temperature-segmenting and batching manner to prepare the microbial organic fertilizer containing the following raw materials in parts by weight: 10-15 parts of activated attapulgite, 25-35 parts of traditional Chinese medicine residues, 15-25 parts of straws, 15-30 parts of livestock manure, 3-8 parts of CaO, 1-3 parts of fermenting bacteria and 1-3 parts of functional bacteria. The traditional Chinese medicine residues used in the invention contain a lot of crude proteins, crude fat, crude fibers, vitamins, trace elements iron, manganese, zinc, calcium and magnesium and biological active substances; the produced organic fertilizer has the advantages of promoting yield increaseof crops, improving qualit
