污染农田茭白镉积累特点及茭白安全生产的土壤镉阈值OACSTPCD
Cd Accumulation Characteristics of Zizania latifolia in Polluted Farmland and Safety Threshold of Cd in Producing Areas
为了解茭白对土壤镉的吸收与积累特点,从浙江省镉污染地区的茭白产地同时采集了57对茭白不同器官样(根、短缩茎、叶、肉质茎)与耕层土样,分析了茭白不同器官中镉的积累规律及其与土壤镉含量的关系.结果表明:茭白不同器官中镉含量由高至低依次为:根＞短缩茎＞叶＞肉质茎,根、短缩茎、叶、肉质茎中镉的平均富集系数分别为1.553、0.675、0.222、0.077.茭白各器官中镉的积累与土壤镉污染水平呈正相关,相关系数由高至低顺次为根>短缩茎>叶&g…查看全部>>
To understand the characteristics of Cd uptake and accumulation by Zizania latifolia,57 pairs of Zizania latifolia organs(roots,short stems,leaves and fleshy stems)and topsoil samples were collected from Cd-polluted fields in Zhejiang Province to study the accumulation of Cd in different organs of Zizania latifolia and its relationship with soil Cd content.The results showed that Cd accumulated in different organs of Zizania latifolia decreased in the order …查看全部>>
