The invention relates to the technical field of biological fermentation, and particularly discloses a fermentation inoculant and an anaerobic fermentation method of corn straw. The fermentation inoculant provided by the invention comprises bacillus stearothermophilus, bacillus amyloliquefaciens, clostridium butyricum and bacteroides. Furthermore, the fermentation bacterial agent is prepared from the following components in parts by weight: 2.3 to 2.7 parts of bacillus stearothermophilus, 1.5 to 2.2 parts of bacillus amyloliquefaciens, 1.0 to 1.2 parts of clostridium butyricum and 1.0 to 1.2 parts of bacteroides; the invention further provides an anaerobic fermentation method of the corn straw, and three-section gradient fermentation is adopted. According to the fermentation inoculant and the anaerobic fermentation method of the corn straw, provided by the invention, the fermentation time of the corn straw can be shortened, the conversion rate of the corn straw is improved, and efficient utilization of waste r
