通过应用综合生态环境效益法，以灯心草为指示植物可以将土壤环境质量二级标准上限值设定为土壤中5种重金属的临界毒性效应值。

POD and SOD activities in Juncus Effuses increased first and then decreased afterwards, while CAT activity decreased linearly. In gerneral, the enzyme activities were gradually activated when the concentration of heavy metals was within the lower concentration range of the soil environmental quality which indicated their synergic resistance to heavy metal stress to a certain degree.

在接近土壤环境质量标准低浓度设计范围内，灯心草3种保护酶有逐渐被激活的趋势，表现出一定的协调性共同抵制重金属的毒害。

Pot experiment was used to study the effects of four amendments (calcium-magnesium phosphate, sepiolite, calcium carbonate and organic manure) on the growth and heavy metal accumulation characters of Juncus effuses grown on the soil contaminated by lead/zinc mine tailings .

通过盆栽试验研究了铅锌尾矿污染土壤上施用钙镁磷肥、海泡石、碳酸钙和有机肥等4种改良剂对灯心草生长发育和产量以及重金属元素Cu、Cd、Pb、Zn积累特性的影响，并分析了施用改良剂后土壤pH值和土壤中有效态重金属含量的变化。

Then, the whole herb of Juncus effusus was extracted with 95% ethanol. The ethanolic extract was further separated with petroether, chloroform, ethyl acetate and methanol in turn to give four fractions.

用95%乙醇提取制备了总提取物，然后将总提物用石油醚、氯仿、乙酸乙酯、甲醇依次萃取，分成极性大小不同的部位，通过药理活性筛选后确定了有效部位为乙酸乙酯部分。

Eco-toxicology effects of compound stress of Cu, Cd, Pb, Zn and As on growth, chlorophyll content and protective enzyme of Juncus Effuses were studied using pot culture. Concentrations of the heavy metals in the soil were designed according to the State Soil Environmental Quality Standard. Considering practical application, soils contaminated with tailings and wastewater from Lead/Zinc mining were also used in the experiment.

通过盆栽试验，以现行土壤环境质量标准为浓度设置依据并结合实际污染土壤研究了不同处理水平的Cu、Cd、Pb、Zn、As 5种重金属复合污染对灯心草生长、叶绿素含量及保护酶系统的影响。
