5种旱稻对酸性Cd污染土壤的提取修复潜能研究
Study of cadmium phytoextraction capacity of different rice cultivars growing in acid soil
为探究旱稻对酸性Cd污染土壤的植物提取修复潜能，采用盆栽方法，研究了Cd在水稻各器官的分布、迁移能力以及累积量。结果表明，常规籼型水稻地上部生物量均显著高于旱稻；Cd在水稻不同部位含量分布依次为：根系>茎秆>叶>谷壳>糙米；旱稻转移系数TF比常规水稻强，顺序依次为：赣农旱稻1号>中旱209>中旱211≈旱优3号>沪旱15号>常规中稻Ⅱ优明86≈常规中籼稻扬Ⅱ优6号；旱稻对土壤全量和有效量Cd的生物富集系数BCF均比常规水稻强，顺序均为：赣农旱稻1号>中旱211>中旱209>旱优3号>沪旱15号>常规中稻Ⅱ优明86>常规中籼稻扬Ⅱ优6号；各品种修复供试Cd污染土壤至福建农业土壤重金属二级标准所需的修复时间，以全Cd为基准依次为(年)：常规中籼稻扬Ⅱ优6号(30.3)>常规中稻Ⅱ优明86(11.4)>沪旱15号(10.0)>旱优3号(9.8)>中旱209(7.0)>中旱211(6.5)>赣农旱稻1号(4.7)，以有效Cd为基准依次为(年)：常规中籼稻扬Ⅱ优6号(17.4)>常规中稻Ⅱ优明86(6.6)>沪旱15号(5.8)>旱优3号(5.6)>中旱209(4.0)>中旱211(3.8)>赣农旱稻1号(2.7)。
o explore the upland rice to acidic Cd contaminated soil by plant extracts repair potential, The Cd in the regeneration of the organs distribution, migration and accumulation quantity ability. The results show that Cd in different parts content distribution for root > stem > leaf > chaff > rice husk. The capacity of migrate the copper were Gan None .1 > Zhong Han.209> Zhong Han.211≈Hanyou.3 > Hu Han.15 > Common medium rice ⅡU Ming.86≈Common medium rice Yang II U.6. The accumulation ability of were Gan None .1> Zhong Han.211> Zhong Han.209> Hanyou3 > Hu Han.15 > Common medium rice ⅡU Ming.86> Common medium rice Yang II U.6. The extraction of fixed the soil in the order total content and effective quantity Cd length of time were Common medium rice Yang II U.6 (30.3, 17.4 years)> Common medium rice ⅡU Ming.86 (11.4,6.6 years)> Hu Han.15 (10.0, 5.8 years)> Hanyou3 (9.8, 5.6 years)> Zhong Han.209 (7.0, 4.0 years)> Zhong Han.211 (6.5, 3.8 years)> Gan None .1 (4.7, 2.7 years).
