In this study，high efficient and multifunctional strains were screened from lichen fungi，and high efficient microbial fertilizer was developed.Hydrolytic circle method was used at the initial screening，then DNS method，molybdenum-antimony colorimetric method and plate antithetic method were used to qualitative determine the strains with high efficiency in degrading cellulose，dissolving inorganic phosphorus and inhibiting pathogen activity.Different combinations of strain were used to develop microbial inoculant，and pot experiments were carried out to select the best combination for promoting growth.Efficiently degrading cellulose strains from 120 lichen fungi were 1905-2，1909-7，1913-6 and 1915-2.Among them，strains 1905-2 and 1915-2 had the activity of inhibiting pathogenic fungus.Efficiently dissolving phosphorous strain was 1905-4，which also had the activity of inhibiting pathogen.Combined with morphological and molecular identification，strains 1905-2 were identified as Tolypocladium tropicale，1905-4 as Aspergillus tubingensis，1909-7 as Aspergillus aflatoxiformans，1913-6 as Penicillium chrysogenum，and 1915-2 as Purpureocillium by combining morphology and molecular sequence Lilacinum.The combination 5 (1905-4，1915-2)had the advantages in increasing stem length and wet weight，and it had the best effect in degrading cellulose and dissolving phosphorus.Therefore，the combination 5 was selected as the final microbial inoculant.Selecting high-efficiency functional strains from lichen fungi and developing compound microbial inoculant with high efficiency in degrading cellulose，dissolving inorganic phosphorus and inhibiting pathogen can provide the theoretical basis for the development and utilization of microbial resources and the high-yielding ecological microbial inoculant.
