This study assessed the impact of phytoremediation on reducing the residual concentration of metolachlor in soil treated with doses of 530.7 and 1061.4 g/ha and its effect on microbial biodiversity in contaminated areas. For the plant species and , a significant efficacy of 54.5 and 36.4% was observed in the dissipation of the herbicide, especially at higher doses. Although metolachlor application reduced soil microbial biodiversity, phytoremediating plants, especially , promoted greater richness and distribution of microbial species, mitigating the negative effects of the herbicide. Principal component analysis revealed the influence of these plants and metolachlor on the composition of the microbial community. These results highlight the importance of phytoremediation in promoting soil biodiversity and reducing herbicide contamination, providing crucial insights for remediation strategies in contaminated areas.
本研究评估了植物修复对降低用530.7和1061.4克/公顷剂量处理过的土壤中异丙甲草胺残留浓度的影响及其对污染区域微生物生物多样性的作用。对于植物物种 和 ，在除草剂消散方面观察到显著功效，分别为54.5%和36.4%，尤其是在较高剂量时。尽管施用异丙甲草胺降低了土壤微生物生物多样性，但进行植物修复的植物，尤其是 ，促进了微生物物种更丰富的丰富度和分布，减轻了除草剂的负面影响。主成分分析揭示了这些植物和异丙甲草胺对微生物群落组成的影响。这些结果凸显了植物修复在促进土壤生物多样性和减少除草剂污染方面的重要性，为污染区域的修复策略提供了关键见解。
