| 摘 要： | 本文采用室内盆栽试验,在4 kg铜尾矿中分别加入腐熟鸡粪0、8、16、32 g,记作JF0(CK)、JFB、JF16、JF32处理方式.研究不同比例腐熟鸡粪改良铜尾矿后对菊科植物串叶松香草(Silphium perfoliatum)生长和尾矿基质性质的影响.结果表明:在尾矿基质中添加鸡粪改良后,植物株高、冠幅、叶长、叶宽、茎叶生物量、根系生物量、植物体总磷含量均显著增加(P＜0.05),植物根长也有增加.随着串叶松香草的生长,尾矿基质中总氮、总磷含量增加,有效磷含量显著增加(P＜0.05),土壤pH值和有效态Cu、Zn含量有所降低,土壤微生物量C、脲酶和脱氢酶活性提高.相关分析表明,尾矿基质中铵态氮含量与植物叶长、茎叶生物量、茎叶总氮呈显著正相关(P＜0.05),有效磷含量与植物株高、冠幅、叶长、叶宽、茎叶生物量、根系生物量、茎叶总磷、根系总磷(P＜0.01)和土壤脱氢酶活性(P＜0.05)呈显著或极显著正相关,总磷含量与植物冠幅、叶长、叶宽、茎叶生物量、茎叶总磷、根系总磷呈显著正相关(P＜0.05).综合分析表明,串叶松香草在铜矿业废弃地植被恢复过程中具有较大应用潜力,鸡粪改良效果较好,JF16处理方式较为妥当. |
