Correlation analysis of BIO effect on soil different bacterial composition and chemical properties. A: Redundancy analysis (RDA) of soil differentially active soil bacterial genera and chemical properties (p value = 0.02). B: The correlation analysis of yield, weed control efficiency, soil chemical properties and bacteria communities. Sample names denote the following: BIO50: 750 kg/hm2 BIO-treated soil in 2017 and 2021; BIO100: 1500 kg/hm2 BIO-treated soil in 2017 and 2021; BIO200: 3000 kg/hm2 BIO-treated soil in 2017 and 2021; BIO400: 6000 kg/hm2 BIO-treated soil in 2017 and 2021; BIO800: 12,000 kg/hm2 BIO- treated soil in 2017 and 2021; HPS: herbicide-treated soil in 2017 and 2021; CBF: common bio-fertilizer in 2017 and 2021; CBFS: common bio-fertilizer-treated soil in 2017 and 2021, and CK: untreated control soil in 2017 and 2021
