| 摘 要： | 采用盆栽土壤模拟试验方法,以油菜（Brassica campestris）为供试植物,通过向土壤中接种微生物,研究了四种菌株JA1,JA2,JA3,JA4对油菜吸收Cd的效果影响。结果表明：菌株JA1,JA2,JA4不仅可以促进植株的生长,分别使油菜的生物量提高17%,28%和32%,而且增强了植株对土壤Cd的吸收,使油菜地上部富集量较对照提高了26.8%,48.8%和65.9%,植物提取量较对照增加了48.9%,76.1%和119%,并且可有效促进土壤Cd的活化,分别使土壤Cd的有效态含量提高了25.9%,59.2%和41.9%;菌株JA3则使其植株地上部富集量、植物提取量和土壤Cd有效态含量降低,较对照降低了14.6%,11.8%和13.6%。各处理的叶绿素和可溶性蛋白含量均略高于对照。

| Abstract: | The study was conducted to investigate the effects of microbial inoculation on bioavailability of Cd in soil and Cd uptake by rape(Brassica campestris)as a Cd accumulator using a pot experiment.The results showed that strains JA1,JA2,JA4 promoted the biomass of rape,accounting for 17%,28% and 32% respectively.Furthermore,strain JA1,JA2,JA4 inoculation enhanced the concentrations of available Cd in the soil by 25.9%,59.2%,41.9% and also increased the Cd concentrations in rape roots by 48.9%,76.1%,119% and in... |
