摘    要:采用温室盆栽试验,对生长于污泥中的几种耐性植物遏蓝菜属(Thlaspigoesingense)、羽叶鬼针草(Bidensmaxi-mowiczianaOett)、酸模(RumexacetosaL.)、紫苜蓿(MedicogosativaL.)和印度芥茉(Indianmustard)的植物干重、体内重金属(Cu、Zn、Pb、Cd)的含量、叶片中叶绿素含量和植物根系对重金属的活化率做了研究。结果表明,生长于污泥中的植物其干重比对照均有不同程度的增加,其中羽叶鬼针草与对照相比差异极显著;不同植物对不同重金属的吸收量亦不同;各种植物叶片中的叶绿素含量变化不同,与对照相比,差异不显著;遏蓝菜对Cu、Zn的活化率最高,印度芥茉对Cd的活化率最高。

关 键 词:污泥  重金属  响应  活化作用

Abstract:To study the improvement of plants on biosolids and the activated impact of plant roots on heavy metals, a test was conducted in green-house. Thestudy researched the following parameters: dry weights of plants, contents of heavy metals (Cu, Zn, Pb, Cd) and chlophyll in plants, and the activated ratios of plant roots on heavy metal. The results showed that the dry weights of all theplants cultivated in biosolids increased compared with control sample, and the difference between Bidens maximowicziana Oett and control sample was extremely significant. The uptake contents of heavy metals and chlophyll contents in different plants were found to be different, and the difference of chlophyll contents among different plants was subtle compared with the control. Additionally, the activated ratios of Cu and Zn in Thlaspi goesingense were the highest, and so wasCd in Indian mustard.
Keywords:Biosolids  heavy metal  response  activated impact
