Divergent Effects of Fertilizer Regimes on Taxonomic and Functional Compositions of Rhizosphere Bacteria and Fungi in Phoebe bournei Young Plantations Are Associated with Root Exudates

Fertilization is widely acknowledged as being an essential practice to improve forest productivity in ecosystems. However, too little consideration has been given the taxonomic and functional compositions of rhizosphere soil microbes their interactions with root exudates under different fertilizer regimes plantations. Here, we investigated effects four typical (CK, no fertilizer; CF, compound OF, organic CMF, microbial fertilizer) on communities potential groups Phoebe bournei young plantations, well associations physicochemical properties exudates. These results showed that strikingly affected community alpha diversity indices. The pathotroph was dominant fungal guild. With applications three fertilizations, relative abundances plant pathogen arbuscular mycorrhiza increased. bacteria highest OF regime, more powerfully by amendment CMF. Additionally, while simultaneously influenced physiochemical factors exudates, bacterial mostly impacted More importantly, application CF induced dramatic growths Fusarium, CMF treatment including Bacillus suppressed development Fusarium via adjusting species. Overall, our findings exhibit divergent responses fungi P. provides benefits for bacteria, can help alleviate inhibition through changing pathogens.
