Bacterial liquid for promoting aerobic fermentation heat production of corn straws as well as preparation method and application of bacterial liquid

The invention discloses a bacterial liquid for promoting straw aerobic fermentation heat production. The bacterial liquid comprises low-temperature starting bacteria and high-temperature cellulose degrading bacteria; the preparation process comprises the following steps: culturing the low-temperature starting bacteria and the high-temperature cellulose degrading bacteria to a logarithmic phase to obtain a low-temperature starting bacteria solution and a high-temperature cellulose degrading bacteria solution; mixing the low-temperature starting bacterial liquid and the high-temperature cellulose degradation bacterial liquid into a fermentation culture medium, and carrying out mixed culture to obtain bacterial liquid; applying the microbial inoculum to preparation of a solution for promoting aerobic fermentation and heat production of the straws, and enabling the straws to be subjected to aerobic fermentation, so the straws can be quickly fermented to produce heat. 本发明公开了一种促进秸秆好氧发酵产热的菌液，所述菌液包括：低温启动菌和高温纤维素降解菌；制备
