The Effects of Microbial Inoculants on Bacterial Communities of the Rhizosphere Soil of Maize

The bacterial community of rhizosphere soil maintains properties, regulates the microbiome, improves productivity, and sustains agriculture. However, structure function communities have been interrupted or destroyed by unreasonable agricultural practices, especially excessive use chemical fertilizers. Microbial inoculants, regarded as harmless, effective, environmentally friendly amendments, are receiving more attention. Herein, effects three microbial inoculant M two commercial inoculants (A S), on maize under nitrogen application rates were compared. Bacterial treated with different from those non-inoculant control. OTU (operational taxonomic unit) numbers alpha diversity indices decreased except for in CF group. Beta showed structures changed compared Furthermore, key phylotypes analyses exhibited differences biomarkers between treatments visually. Overall, had shared unique abilities regulating other increasing potentially beneficial bacteria decreasing negative. This work provides a theoretical basis sustainable
