| 摘 要： | 对种植在安化山区镉污染农田中的亚麻生育期、农艺性状与原茎产量及吸镉特性进行了初步研究,供试品种“阿里安”两年平均产量达4207.5kg/hm2,表明亚麻对镉污染农田有较好的适应性;同时分析了亚麻各器官及整个单株的镉富积和转运能力,实验证实亚麻对镉有一定的富积作用,富积系数(BC)最高达到4.33,对于整株亚麻镉含量表现为:地下根>地上茎叶。

| Abstract: | In the paper,ecological adaptability of 2 flax varieties was simply studied on growth duration,agronomic characters,yields of raw-stem and absorbing Cd power.The results showed that it was feasible to cultivate flax in Cd polluted agricultural land of Anhua county,and flax could make Cd accumulated and transfered,the most bio-accumulation coefficient(BC) was 4.33,the contents of Cd in the root were more than contents in the up-ground of flax. |
