摘要： To mitigate the soil sloughing and hypoxia from long-term reclaimed water irrigation through ozone micro-nano bubbles (O-3-MNBs) technology, we planted maize in a greenhouse to assess the impacts of O-3-MNBs (OG), reclaimed water (RW), and reclaimed water-O-3-MNBs (ORW) drip irrigation on the rhizosphere soil and bacterial communities during the nutrient growth of maize. The results revealed that, compared with the CK treatment, both irrigation treatments significantly increased the available nitrogen (AN) and potassium (AK) contents, with the highest AN and AK contents found in the soils irrigated with reclaimed water at 96.13 +/- 1.76 mg kg(-1) and 355.6 +/- 13.89 mg kg(-1), respectively. High-throughput sequencing revealed that reclaimed water-aerated drip irrigation improved the diversity of the rhizobacterial community, with the dominant phyla being Proteobacteria and Actinobacteria. Verrucomicrobia, Actinomycetia (class), and Bacilli (class) were identified as biomarker species for the OG, ORW, and RW treatments, respectively. AN and AK are pivotal factors influencing bacterial distribution. A structural equation model revealed that reclaimed water-aerated drip irrigation directly improved soil fertility, thereby influencing the structure and diversity of rhizosphere bacterial communities. This study offers a new technology for the safe and efficient use of reclaimed water while also promoting the development of modern agriculture.
