高丹草在低浓度铜-镉-菲复合胁迫下的生长及响应特性OA北大核心CSTPCD
Growth and response characteristics of Sorghum-sudan grass under combined low stress of copper-cadmium-phenanthrene
针对焦化厂等工矿废弃地残留的重金属-多环芳烃污染风险高、低成本绿色环保技术缺乏等问题,通过田间试验,研究低浓度铜-镉-菲复合胁迫下高丹草萌芽率,生物量,铜、镉累积,菲去除及叶绿素含量的变化规律,探索其生长及污染物迁移累积等响应特性.结果表明:10 mg·kg-1菲和100 mg·kg-1铜复合胁迫可促进高丹草生长,茎叶和根系生物量分别增加14.7%和8.1%,5 mg·kg-1镉抑制了高丹草生长.铜、镉主要累积在高丹草根部,菲-铜复合胁迫可促进铜…查看全部>>
To study the growth and response characteristics of Sorghum-sudan grass under low concentrations of combined heavy metal-polycyclic aromatic hydrocarbon pollution,the germination rate changes,biomass,accumulation of copper,cadmium and phenanthrene degradation and chlorophyll composition were detected by field experiments.The results showed that the combined stress of 10 mg·kg-1 phenanthrene and 100 mg·kg-1 copper could promote Sorghum-sudan grass growth,incr…查看全部>>
