| 1 | 黄麻修复重度镉污染农田的品种筛选显示文摘为研究不同黄麻品种对土壤重金属镉污染的修复能力,以5个黄麻品种为材料,种植于湖南浏阳的重度镉污染试验农田中。黄麻栽种后,每月测一次根、茎、叶的镉含量,并测定纤维成熟后黄麻各生理性状,计算黄麻镉累积量、富集系数、转移系数等。结果表明:黄麻在重度镉污染农田中仍能正常生长,随着植株的生长,不同黄麻品种和组织间镉含量差异显著(p<0.05),并呈现持续下降趋势;不同黄麻品种的镉富集系数和转移系数均大于1;叶的镉转移能力强于茎。在5个黄麻品种中,中黄麻11号、菜用黄麻3号、桂菜黄麻2号均对重金属镉具有较强的吸收和富集能力,可以用于修复农田镉污染。 | 尹明 杨大为 唐慧娟 潘根 常丽 李建军 邓勇 张翠萍 李德芳 赵立宁 黄思齐 | 2020 | 中国麻业科学2020，42，4： | 6 |
| 2 | 宝景天-小麦轮作修复重金属污染土壤的工程案例显示文摘河北省邢台市某重金属锌、镉污染农田,通过现场采样调查,确定其污染面积约39.09 hm^2,Zn、Cd最大污染浓度为404 mg/kg、2.91 mg/kg。本项目采用八宝景天-小麦轮作的植物修复模式,配合施加重金属活化剂、钝化剂、复合肥等措施提升八宝景天的生物量和对Zn、Cd的吸收量。经过三轮修复,土壤中Zn、Cd平均浓度分别为292.09 mg/kg(修复目标值为300 mg/kg)、0.38 mg/kg(修复目标值为0.6 mg/kg),去除率分别为14.65%和48.7%;小麦籽粒中Zn、Cd平均浓度分别为43.263 mg/kg(标准限值50 mg/kg)、0.059 mg/kg(标准限值0.1 mg/kg),去除率分别为44.05%和42.7%,均达到修复目标要求。 | 陆英 肖满 张文辉 燕虞迪 | 2020 | 环境生态学2020，2，8： | 1 |
| 3 | 不同杀青方式对伴矿景天秸秆干化的影响研究显示文摘为探究伴矿景天秸秆快速干化的方法,通过翻炒杀青、蒸汽杀青、微波杀青和直接阴干4种秸秆处理方式,对离田伴矿景天秸秆的失水速率、失水比例、失水量、含水率及镉(Cd)含量进行分析。结果表明,与直接阴干的秸秆相比,经杀青的秸秆失水速率、失水比例、失水量均较高,最终含水率较低。杀青结束后阴干初期,经翻炒杀青的秸秆失水速率、失水比例、失水量显著高于蒸汽杀青和微波杀青;阴干过程中,经翻炒杀青的秸秆含水率降至70%以下耗时最短仅需120 h,而经蒸汽杀青和微波杀青的秸秆含水率降至70%以下分别需180 h和216 h;阴干结束时,经蒸汽杀青和翻炒杀青的秸秆失水量最多,分别为459.40 g和459.80 g,并且不同杀青方式不会对秸秆Cd萃取总量造成显著影响。对伴矿景天离田秸秆进行杀青处理可以缩短干化周期且不会对秸秆Cd萃取总量造成显著影响;其中翻炒杀青可加速水分逸散,缩短含水率降至70%以下所耗时长,更符合转运、焚烧或其他后端处置措施的要求,该研究为超积累植物工程修复应用的产后处置技术提供了新思路和技术验证。 | 刘书洪 陈锦 蒋慧丹 胡志鑫 贺爱国 戴艳娇 | 2023 | 中国农学通报2023，39，18： | 0 |
| 4 | The effects of different electrode materials on seed germination of Solanum nigrum L.and its Cd accumulation in soil显示文摘The effects of different electrode on Solanum nigrum L.seed germination were determined.The result showed that germination percentage(GP)of seeds in treatment T2(titanium elec-trode)was 26.6%higher than in control(CK,without electric field).High potassium and calcium concentrations were beneficial for seed enzymatic activity in treatment T2,which could partly explain the increase in GP.Cd accumulation(μg/pot)in S.nigrum treated with any electric field was significantly higher(p<0.05)than in CK without electric field.Specif-ically,Cd accumulation under the treatment T3(stainless steel electrode)was the highest both in roots and shoots;this accumulation in shoots and roots were 74.7%and 67.4%higher for stainless steel than in CK.This increase must have been associated with a higher Cd concentration in plants and did not exert a significant effect on the biomass.In par-ticular,Cd concentrations in roots and shoots under stainless steel treatment were both significantly higher than in CK(p<0.05),which had to be related to the higher available Cd concentration in the soil in the middle region.Furthermore,it could be attributed to al-tered soil pH and other soil properties.Moreover,none of the biomasses were significantly affected(p<0.05)by different electrode materials compared to CK. | Lei Xu Huiping Dai Lidia Skuza Shuhe Wei | 2022 | Journal of Environmental Sciences2022，34，3： | 0 |
