摘要
通过野外采样和室内检测,对潍坊典型烟区临朐县植烟土壤、烟用肥料和烟田灌溉水重金属含量和风险进行了调查和分析。结果表明,临朐县植烟土壤和烟用肥料均低于限量标准,烟田灌溉水远低于限量标准,整体风险较低。烟草生产季Cd外源总量占对应耕层土壤含量的比例远高于其它重金属,结合各外源占有比例说明复合肥、钾肥和有机肥中的Cd是临朐烟区土壤重金属外源控制的重点。
The samples of soil, fertilizer and irrigation water were collected in typical tobacco field in Linqu of Weifang, Shandong Province, and the contents of As, Cd, Cr, Hg and Pb in them were detected in laboratory. The result showed that the heavy metals in soil and fertilizers were less than limit standards respectively, and the heavy metals in irrigation water were far less than limit standards. Therefore, the ecological environment of Linqu tobacco-planting region is in low risk of heavy metal pollution. The input of Cd in tobacco-planted season is far more than those of other heavy metals. The analysis of proportions of input sources indicated that the Cd in compound fertilizer, potassic fertilizer and organic fertilizer should be the key of source control.
