Multifunctional microbial agent and application thereof

The invention relates to the technical field of bioengineering, in particular to a multifunctional microbial agent and application thereof. The invention provides a multifunctional microbial agent. The multifunctional microbial agent comprises a complex microbial agent and an adsorbable carrier, the adsorbable carrier comprises livestock and poultry manure, mushroom bran and straw. According to the invention, three new bacillus strains with nitrogen fixation, phosphate solubilizing and potassium solubilizing activities are obtained through screening, and are used as excellent microbial agent production strains. The complex microbial inoculant produced by mixing the microbial inoculant, the exogenous organic raw materials, the animal dung and the crop straws can better improve the soil microbial environment, activate soil immobilized nutrients, promote crop nutrient absorption and improve the yield and quality of crops. 本发明涉及生物工程技术领域，尤其涉及一种多功能微生物菌剂及其应用。本发明提供了一种多功能微生物菌剂，包括复合菌剂和可吸附载体；所述可吸附载体包括畜禽粪便、菌糠和秸秆。本发明通过筛选得
