主 题：Rhizosphere Biochar Fungal community Life strategies Network analysis
摘 要：Soil fungi have many important ecological functions,however,their life strategies and interactions in manure fertilized soils are not well *** aim of this study was to investigate the effects of biochar amendment on the fungal life strategies and species interactions in ryegrass(Lolium perenne L.)rhizosphere soil by high-throughput *** soil treatments were evaluated:soil and pig manure mixture without planting ryegrass and biochar application(bulk soil),mixture with ryegrass planting(rhizosphere soil(RS)),and addition of 2%(w/w)biochar with ryegrass(RS+biochar).Our results indicated that temporal turnover,defined as the slope of linear regression between community similarity and time,was significantly higher in the biochar amendment(slope=-0.2689,p0.0001)relative to the rhizosphere *** biochar addition,the percentage of species employing slow acclimation ecological strategies decreased(from 27% to 17%)and the percentage of sensitive species increased(from 40% to 50%)in comparison to the rhizosphere *** analysis indicated that fungal communities in the biochar amendment enhanced positive correlations compared to the rhizosphere soil and bulk *** equation model indicated that soil pH was the most important factor in altering fungal life strategies and interactions in manure fertilized soils.
