摘要

Background and aims

Albic soils are typically low-productivity, severely restricting sustainable agricultural practices. Improving their fertility and productivity has become a critical issue for enhancing soil use in agriculture.

Methods

In this study, the interactions between rhizosphere microbes and metabolites in maize were investigated under four conditions: control (CK), biochar addition (BC), Piriformospora indica inoculation (PI), and the combination of biochar and P. indica (BP). We used 16S rRNA sequencing and untargeted metabolomics to analyze the effects on maize biomass, photosynthetic parameters, and root growth.

Results

The BP treatment significantly increased maize shoot and root biomass by 81.7% and 85.6%, respectively, compared to the control. Additionally, the BP treatment altered the microbial community structure and metabolite composition, favoring beneficial bacteria such as Bacillus and Lysobacter and promoting the secretion of the differential metabolite isoleucine. Pathway analysis revealed that the BP treatment stimulated isocitrate secretion, which may serve as a metabolic marker.

Conclusion

This study comprehensively elucidates the mechanisms of crop-microbe interactions through a combined analyses of 16S rRNA and untargeted metabolomics. It provides a valuable strategy for improving productivity in albic soil by applying biochar and P. indica.
