    农药对根际微生物群落的影响及潜在风险

    Effects of pesticides on the rhizosphere microbial community and potential risks

    • 摘要: 农药残留是全球面临的重大环境问题。残留于土壤中的农药不仅直接影响植物生长,也会扰乱植物根际微生物群落,除草剂、杀虫剂和杀菌剂等农药均能影响根际微生物群落的结构和功能。本文综述了农药对根际微生物的影响,揭示了农药可通过改变根际微生物间接影响植物生长的风险:农药能改变与碳、氮、硫、磷循环相关根际微生物的丰度,影响植物的营养摄取;也可能抑制部分根际生防菌的生长,改变相关致病菌的丰度并影响植物的免疫功能。研究农药对根际微生物的影响及潜在风险,将有助于更全面评估农药的生态安全,为农药安全创制和使用提供理论依据。

       

      Abstract: Pesticide residue is a major environmental problem worldwide. Pesticide residue in soil not only directly affects plant growth, but also disturbs plant rhizosphere microbial community. Pesticides, including herbicides, insecticides and fungicides, can affect the structure and function of rhizosphere microbial community. In this review, the effects of various pesticides on the rhizosphere microbial community and the risks of indirect effects of pesticides on plant growth by changing rhizosphere microorganisms were summerized. Pesticides can change the abundance of rhizosphere microorganisms, which are related to the soil circulation of carbon, nitrogen, sulfur and phosphorus, and affect the nutrient intake of plants. Pesticides may also inhibit the growth of rhizosphere biocontrol bacteria, which with results in the changes of the abundance of related pathogens and the plant immunity. Studies on the effects of pesticides on rhizosphere microorganisms and their potential risks will help us to assess the ecological risk of pesticides more comprehensively provide theoretical basis for the discovery and safely use of pesticides.
