【摘要】 为探索中草药在赣南稀土尾砂治理中的适应性,选取了7种抗逆性强的中草药,从生长力、耐旱性和耐瘠性三方面对其在稀土尾砂基质上种植的适宜性进行了比较,结果发现:生长力以果桑最优,耐旱性以紫珠草最强,耐瘠性最好的为栀子;综合评分值显示紫珠草、栀子、果桑较好,其次为金银花和菊花,薄荷和金线草综合评分值较低,不适合作为稀土尾砂治理植物推广应用。重金属检测结果显示,在赣南稀土尾砂基质上种植的中草药,其铬、镉和铅等重金属含量均低于《药用植物及制剂外经贸绿色行业标准》(WM/T 2—2004)。经综合评定,紫珠草、栀子、果桑、金银花为适宜用于赣南稀土尾砂治理的中草药品种。更多还原

【Abstract】 To explore the adaption of Chinese herbs to tombarthite tails treatment in south Jiangxi Province,seven kinds of herbs with high stress resistance were selected to be planted to compare with the suitability among the terms of growth force,drought resistance and infertile resistance. It was found that mulberry perform better than the others in growth force,Callicarpa macrophylla more excellent in drought resistance,and Gardenia jasminoides better in infertile resistance. General evaluation showed the composite scores of Callicarpa macrophylla,Gardenia jasminoides and mulberry are higher,then Lonicera japonica and Dendranthema morifolium,and the minimum of Mentha haplocalyx and Antenoron filiforme,which are not suitable for applied in the tombarthite tails treatment. And more,the heavy-mental-element detection showed the level of Cr,Cd,Pb,et al. are lower than that required in Green Standards of Medicinal plants and Preparations for Foreign Trade and Economy( WM/T 2—2004).Therefore,the research suggests the Callicarpa macrophylla,Gardenia jasminoides,mulberry and Lonicera japonica are fit for the treatment of tombarthite tails in South Jiangxi Province.更多还原
