The invention discloses an integrative anaerobic and aerobic fermentation method of straws. The method comprises: weighing straws according to a weight proportion that the volume of each stere methane tank body is corresponding to 55kg straws, crushing the straws, mixing 0.2% by weight of ammonium bicarbonate in the straws, adding the straws in an aerobic fermentation tank through a feed opening, starting a biogas slurry reflux unit, spraying the biogas slurry onto the straws in the aerobic fermentation tank through a spray head, controlling the weight ratio of the straws to the biogas slurry to 1:1, opening the feed opening during the fermentation process to perform aerobic fermentation for 7 days; opening the feed opening through a slot, throwing the straws into the methane tank body, and a layer of mesh plates is arranged in the methane tank body, so that the straws perform anaerobic fermentation above the mesh plates. According to the invention, the technical design is reasonable, the structure of the met
