Integrated farming of rice (IFA), as a time-honored agricultural model, can effectively increase productivity and provide ecological benefits. Rice-wheat rotation rice-crayfish ( Procambarus clarkii ) are two most widely applied IFA patterns in China. In this study, we compared the differences soil microbial communities predicted their functions these models by sequencing 16s rRNA analyzing bioinformation. The results showed that crayfish increased abundance diversity microorganisms. main differentially abundant phyla between groups were Actinobacteriota, Bacteroidota, Desulfobacterota, while genera Bacteroidetes_vadinHA17 , Sphingomonas Thiobacillus . Similarity Percentages (SIMPER) analysis indicated species also had highest contribution to composition groups. Random forest prediction was employed identify potential biomarkers distinguish communities. Spirochaetota identified biomarker phyla. Streptomyces Kribbella Paludibacter could serve genera. Functional Annotation Prokaryotic Taxa (FAPROTAX) revealed dominant bacterial rice-wheat model aerobic chemoheterotrophy chemoheterotrophy. contrast, more diverse, primarily including methylotrophy, human pathogens all methanotrophy. co-occurrence network enhanced modularity community, fewer nodes edges, which implying internal connections. conclusion, wheat planting drove significant paddy fields, with Actinobacteriota Desulfobacterota biomarkers. Compared cultivation, system incorporating richness functions, promoted presence keystone connecting roles. Our study would not only clarify effects different on communities, should valuable insights for future adjusting cropping controlling current problems.
