    摘要:

    铜污染是严重影响药用植物生长发育的环境问题之一,为了明确人参对铜元素吸收规律和铜污染基质养分有效性影响,以两年生和三年生人参为试验材料,设置0、100、300、500和1000 mg/kg共5个铜离子浓度。结果表明,随着铜处理浓度增加,两年生人参和三年生人参根系活力均出现下降趋势,最多均在1000 mg/kg铜处理时分别显著下降62.33%和44.18%。两年生和三年生人参各时期铜含量均随着处理浓度的增加显著增加且均在绿果期达到基本稳定,红果期略有上升,在1000 mg/kg铜处理时两年生人参根、茎、叶分别显著上升214.03%、93.83%、216.03%,三年生人参根、茎、叶分别显著上升505.65%、337.84%、189.11%。铜处理后基质有效磷、碱解氮、速效钾含量和pH均显著下降,最多分别显著下降57.24%、34.78%、32.61%和22.06%。铜处理会显著改变人参对铁、锰和锌的吸收,在绿果期时,随着处理浓度的增加,两年生人参根部锌、铁和锰在1000 mg/kg铜处理时分别显著下降29.43%、20.71%和56.75%,叶片分别显著下降34.32%、31.62%和47.26%,三年生人参根部锌、铁和锰在1000 mg/kg铜处理时分别显著下降28.54%、19.91%和46.64%,叶片分别显著下降30.25%、16.56%和43.23%,两年生人参微量元素变化略高于三年生人参。总体上来看,三年生人参整体各部位铜含量高于两年生人参,人参各部位铜含量随处理浓度增加而上升。两年生和三年生人参在展叶期到绿果期过程铜吸收速率最快,在绿果期基本达到稳定。绿果期到红果期有略微上升但不明显。铜处理会降低基质养分有效性,也会阻碍人参对锌、铁和锰的吸收。

    Abstract:

    Copper pollution is one of the environmental issues that seriously affects the growth and development of medicinal plants. In order to clarify the absorption pattern of copper elements by ginseng and the influence of copper pollution on the effectiveness of substrate nutrients,two-year-old and three-year-old ginseng were selected as experimental materials,and five copper ion concentrations of 0,100,300,500 and 1000 mg/kg were set up. The results showed that with the increase of copper treatment concentration,the root vitality of both two-year-old and three-year-old ginseng showed a decreasing trend,with the most significant decrease of 62.33% and 44.18%,respectively,under the treatment of 1000 mg/kg copper. The copper content of ginseng at different stages increased significantly with the increase of treatment concentration,reaching a basic stability in the green fruit stage,slightly increasing in the red fruit stage. Under the treatment of 1000 mg/kg copper,the root,stem and leaf of two-year-old ginseng increased significantly by 214.03%,93.83% and 216.03%,respectively,while the root,stem and leaf of three-year-old ginseng increased significantly by 505.65%,337.84% and 189.11%,respectively. After being treated with copper application,the contents of available phosphorus,alkaline hydrolysis nitrogen,available potassium and pH in the substrate decreased significantly,with the most significant decrease of 57.24%,34.78%,32.61% and 22.06%,respectively. Copper treatment significantly altered the absorption of iron,manganse and zinc by ginseng. In the green fruit stage,with the increase of treatment concentration,the root zinc,iron and manganse of two-year-old ginseng decreased significantly by 29.43%,20.71% and 56.75% under the treatment of 1000 mg/kg copper,while the leaf decreased significantly by 34.32%,31.62% and 47.26%,respectively. The root zinc,iron and manganse of three-year-old ginseng decreased significantly by 28.54%,19.91% and 46.64% under the treatment of 1000 mg/kg copper,while the leaf decreased significantly by 30.25%,16.56% and 43.23%,respectively. The changes in trace elements of two-year-old ginseng were slightly higher than those of three-year-old ginseng. Overall,the copper content in all parts of three-year-old ginseng was higher than that of two-year-old ginseng,and the copper content in ginseng increased with the increase of treatment concentration. The absorption rate of copper by both two-year-old and three-year-old ginseng was the highest during the leaf unfolding stage to the green fruit stage,and reached a basic stability in the green fruit stage. There was a slight increase from the green fruit stage to the red fruit stage,but it was not significant. Copper treatment reduced the effectiveness of substrate nutrients and also hindered the absorption of zinc,iron,and manganse by ginseng.
