With the development of modern agriculture, the pollution caused by the use of chemical fertilizers and pesticides has become a serious problem, posing a threat to human health and the living environment. The remediation of plant microorganisms has been seen as an economical, effective, and eco-friendly method of cleaning up soils contaminated with organophosphorus pesticides. In this study, white-rot fungi were immobilized by adsorption method, a plant-microbial remediation met was established. The data results show that after 30 days, the combined remediation system for corn microbes increased the rate of chlorpyrifos degradation by 18% compared to the single remediation of the plant, and the rate of combined remediation of ryegrass microbes increased by 23%. The effect of CPF content in soil on the combined remediation is mainly reflected in the significant difference in the number of microorganisms ( < 0.05). In this article, plant-microbial remediation were applied to soil contaminated by CPF, which provides a new idea for the remediation of pesticide-contaminated soil. Combined bioremediation may be a better alternative to mitigate the impact of high pollution on microorganisms at different pollutant concentrations compared to single microbial remediation or phytoremediation.
随着现代农业的发展,化肥和农药使用所造成的污染已成为一个严重问题,对人类健康和生存环境构成威胁。植物微生物修复被视为一种经济、有效且环保的清理受有机磷农药污染土壤的方法。在本研究中,通过吸附法固定白腐真菌,建立了一种植物-微生物修复方法。数据结果表明,30天后,玉米微生物联合修复系统使毒死蜱降解率比植物单一修复提高了18%,黑麦草微生物联合修复率提高了23%。土壤中毒死蜱含量对联合修复的影响主要体现在微生物数量的显著差异(<0.05)。本文将植物-微生物修复应用于受毒死蜱污染的土壤,为农药污染土壤的修复提供了新思路。与单一微生物修复或植物修复相比,联合生物修复可能是减轻不同污染物浓度下高污染对微生物影响的更好选择。
