摘要
对赣州烟田不同来源的灌溉水以及不同类型肥料中的5种重金属含量进行了分析与评价。结果发现:赣州烟田灌溉水有96.55%的样品处于清洁水平,灌溉水中As、Cd和Hg含量有显著的地域差异,不同来源灌溉水样品仅Cd含量有显著差异;赣州烟用肥料有96.67%的样品处于清洁水平,不同类型肥料的As、Cd、Cr和Hg含量差异显著,其中有机肥中As、Cd和Hg的含量较高,磷肥中的Cr含量和复混肥中的As含量也较高。
The contents of 5 kinds of heavy metals in different sources of irrigation water and different types of fertilizer for Gan- zhou tobacco field were analyzed and evaluated. The results showed that 96.5 % of irrigation water samples were at clean level. As, Cd and Hg contents in irrigation water had significant geographical difference. There was significant difference only in Cd content a- mong different sources of irrigation water samples. 96.67% of fertilizer samples were at clean level. As, Cd, Cr and Hg contents in different types of fertilizer samples were significantly different. Organic fertilizer contained higher As, Cd and Hg. Cr content in phosphate fertilizer and As content in compound fertilizer were higher than that in other fertilizers.
