主 题：fungal community mixed leaf litter non-additive effect Pinus massoniana high-throughput sequencing
摘 要：Aims The conifer litter is fairly recalcitrant and nutrient poor,and broadleaved litter promotes coniferous litter decomposition by increasing degradable nutrients and promoting microbial *** Pinus massoniana litter and three broadleaved litters may increase the diversity and abundance of fungal decomposers compared with those in *** litter and vary depending on the number and proportion of broadleaved species *** We analysed the composition and diversity of fungal communities during mixed litter decomposition in southwestern China with 35 treatments(***,Toona sinensis,Cinnamomum camphora and Sassafras tzumu litter)using Illumina high-throughput *** Findings The mixed litters increased fungal diversity and richness compared with those in the single-species litter,except in the following treatments:*** litter accounting for 70%-80%in the ***+***,***+***+*** and ***+***+*** combinations,and ***+***+***+*** combination with small proportion of *** *** diversity and richness of the 7:1:2 combination of ***+***+*** were significantly higher than those in the other *** and Basidiomycota were the dominant phyla,and Aspergillus was the most abundant *** decomposition of litters from one needleleaf and one broadleaved species(6:4)and one needleleaf species and two broadleaved species(broadleaved litter accounting for 30%-40%)exhibited synergistic interactions throughout the decomposition process,and the relative abundance of fungi that decompose refractory substances *** ***+***+*** combination and a 30%-40%broadleaf litter proportion increased fungal diversity and accelerated the decomposition of recalcitrant coniferous ***,*** and *** are a potential candidate species for mixed planting with ***
