The invention relates to the technical field of biological agents, in particular to a nitrogen-fixing microorganism complex microbial inoculant and an application thereof. The complex microbial inoculant comprises bacillus licheniformis and aspergillus fumigatus; the complex microbial inoculant can efficiently promote nitrogen accumulation in a vinasse organic fertilizer production process and enhance the fertilizer efficiency of vinasse organic fertilizer; and all the used strains are screened from a vinasse fermentation environment, so that the utilization of the strains is friendly to the ecological environment, safe and free of secondary pollution. 本发明涉及生物菌剂技术领域，尤其是一种固氮微生物复合菌剂及其应用，所述的复合菌剂包含地衣芽孢杆菌(Bacillus licheniformis)和烟曲霉(Aspergillus fumigatus)；本发明所述的复合菌剂能够高效的促进酒糟有机肥制作过程中氮素的积累，提高酒糟有机肥肥效；且所用菌株均筛选自酒糟发酵环境，其利用对生态环境友好，安全无二次污染。
