The objective of this study was to investigate the fungal community succession and variations in chicken manure (CM) compost with different concentration of bamboo biochar (BB) as additive via the using of metagenomics method. The consequent obviously revealed that Chytridiomycota, Mucoromycota, Ascomycota and Basidiomycota were the dominant phylum, while Batrachochytrium, Funneliformis, Mucor, Phizophagus and Pyronema were the pre-dominant genera in each treatment. Redundancy analyses indicated that higher dosage of biochar applied treatments has significant correlation between fungal communities and environmental factors. The diversity of fungal community was analogous but the relative abundance (RA) was inconsistent among the all treatments. In addition, the principal component analysis was also confirmed that T5 and T6 treatments have considerably correlation than other treatments. However, the mean value of RA remained maximum in higher dosage of biochar blended treatments. Ultimately, the RA of different fungal genus and species were influenced in CM compost by the BB amendment.
