土培条件下东南景天对镉的耐性和富集特性的研究OA
Study on Tolerance and Enrichment Characteristics of Sedum alfredii Hance to Cd in Soil Culture
[目的] 探讨土培条件下东南景天矿山与非矿山生态型植物对Cd耐性和富集能力的差异.[方法] 采用土培盆栽的方法,以向水稻土中加入不同量的镉作为处理,研究东南景天两种生态型植物在不同镉含量土壤中的生长反应以及体内镉含量与积累量变化.[结果] 两种生态型植物对土壤中不同含量Cd的生长反应不同,矿山生态型对土壤Cd的耐受阈值为300 mg/kg,非矿山生态型为50mg/kg.矿山生态型地上部最大Cd含量为893 mg/kg,根部最大Cd含量为344m…查看全部>>
[Objective] To reveal the differences of tolerance and uptake characteristics of cadmium in soil between mined ecotype and nonmined plants of 5. Alfredii. [ Method ] Using pot culture, different amount of Cd were put into soil as treatment, to study the growth responses of two ecotypes plants of S. Alfredii in soil with different Cd content and the change of Cd content and accumulation. [ Result] The growth responses were different obviously between the two …查看全部>>
