摘要
土壤对农药的吸附作用是农药在土壤中的重要迁移转化行为之一,它对土壤环境质量的变化有着重要的影响。阐述了农药在土壤中吸附的几种作用机理,以及影响农药吸附的主要因素,例如土壤有机质、粘土矿物、pH值、离子强度、温度和表面活性剂等,并提出了今后农药吸附的研究方向。
The absorption of pesticides is one of the most important behaviors of transference and transformation of pesticides in soils,and it also plays significant role in the soil environment.Several absorption mechanisms were described in this paper,and the factors influencing the pesticides＇ absorption such as soil organic matter,clay mineral,pH value,ionic strength,temperature,surfactant and so on,were discussed.Moreover,the tendency of the study on the absorption of pesticides in soils was also put forward.
