| description | Sulfonylurea herbicides (SH) are widely used throughout the world. In this paper, the degradation of sulfonylurea herbicides (SH) in eight different agricultural soils was studied by exploring the synergism between microbial consortium (MC) and plants. In the experiment, chlorimuron with a concentration of 50 mg/L was used as the only carbon source to domesticate and prepare the MC. The degradation of six sulfonylurea herbicides was determined, among which bensulfuron (BN), due to its better degradation effects, was selected. The best degradation conditions of BN were determined as follows: pH 7, 20 °C, and BN concentration 20 mg/L, and after 20 days, the degradation rate of BN by MC reached 90.49%. The physical and chemical properties of eight different agricultural soils were compared, and the correlation between them and the degradation effect of BN was analyzed. When plants were combined with 3% MC to remediate BN-contaminated soil, it was beneficial to plant growth, and the degradation rate of BN was the highest (81%) after 25 days. In addition, the content of soil urease and soil catalase in the soil increased to 449 ug/g and 12.19 mmol/g after 25 days of combined remediation. The results showed an effective bioremediation strategy to restore agricultural soil contaminated by BN. |
