摘要

Purpose

Given that conventional rice production relies heavily on chemical fertilizers and pesticides, this study aimed to evaluate whether the combined application of micro‑nano bubble (MNB) technology and microbial agent (MA) can serve as an innovative approach that simultaneously enhances yield and ecological sustainability through improved nutrient use efficiency and soil health, thereby synergistically promoting rice growth.

Methods

Pot experiments were conducted using rice seedlings grown from seeds that were initially soaked in the respective treatment water for 3 days. The seedlings were then cultivated for 50 days in paddy soil collected from a rice field in Shanghai, China. Four treatments were established: a control group (CK, receiving clear water), MA alone (MA), MNB alone (MNB), and the combined MNB and MA (MNB-MA). The corresponding treatment water was applied not only during the initial soaking but also through regular irrigation every 1–3 days throughout the entire 50-day cultivation period. Rice growth traits, soil physicochemical parameters, microbial community composition, and rice transcriptomic profiles were measured.

Results

The MNB-MA treatment significantly improved seedling development, with sprout and root lengths increasing by 2.01% and 10.89%, respectively. It enhanced nutrient utilization by increasing phosphorus uptake, raising soil pH, reducing salinity, and improving cation exchange capacity. MNB-MA also enriched microbial richness and diversity, stabilizing plant–soil microbial interactions and promoting ecological balance. Transcriptomic analysis revealed that differentially expressed genes were enriched in catalytic activity, binding, and metabolic processes, particularly in ribosome-related pathways, highlighting a molecular basis for improved growth.

Conclusion

The combined MNB-MA treatment synergistically enhances rice performance and soil fertility through complementary effects on nutrient availability, microbial community structure, and gene expression.
