土壤中农药的迁移转化规律及其影响农药在土壤中残留、降解的环境因素

ENVIRONMENTAL FACTOR THAT THE MIGRATION OF PESTICIDE TRANSFORMS THE LAW AND INFLUENCESPESTICIDE TO REMAIN IN THE SOIL,DDEGRADE IN THE SOIL

农药在土壤中的残留是对农业环境造成污染的一大根源。本文介绍了农药在土壤中降解转化的主要途径及机理,包括微生物降解、水解和光解,分析了土壤中不同环境因素(有机质、湿度、温度、pH值、根系分泌物和粒径等)对农药降解和转化过程的影响,展望了今后的研究方向,旨在为进一步治理和修复土壤的农药污染提供依据。

The pesticide residues in the soil are causing a great origin of pollution to the agricultural environment,.This text has introduced pesticide and degraded main route and mechanism transformed in the soil,including the little biodegradation,hydrolysis and photodissociation,have analyzed different environmental factors in the soil(Organic matter,humidity,temperature,pH,roots secretion and a foot-path,etc).Degrade and transform the influence of the course on pesticide,has looked forward to the research direction in the future,aim at offering basis for further controlling and repairing the pollution by pesticides of the soil.
