Integrated cultivation practices help reduce economic costs and increase crop yield. However, it is unclear how integrated improve soil microbial diversity its related mechanism in rice field. Therefore, four i.e., no N application (N0), local farmers’ practice (FP), high-yield high-efficiency (HYEY), super-high-yield practice, impacts on properties structure composition of community were explored. Compared with N0, SHY treatment, significantly increased alkaline nitrogen organic matter contents. HYHE treatments altered fungal Alpha diversity. Based Venn diagram analysis, the bacterial communities under all was similar, but different compositions communities. Cluster analysis indicates that Proteobacteria absolute dominant group communities, Chloroflexi, Bacteroidetes, Acidobacteria group. Different methods also led to changes main factors affecting bacteria fungi composition. Available potassium environmental affected bacteria, strong available soil. Correlation network showed HYEY substantially number positive correlations among fungi. To sum up, beneficial management options terms improved fertility respectively.
