This study was designed to compare the initial method for phytoremediation involving germination and transplantation. The study was also to determine the tolerance efficiency of Panicum maximum (Purple guinea grass) and Helianthus annuus (Sunflower) in TNT-contaminated soil and nZVI-contaminated soil. It was found that the transplantation of Panicum maximum and Helianthus annuus was more suitable than germination as the initiate method of nano-phytoremediation potting test. The study also showed that Panicum maximum was more tolerance than Helianthus annuus in TNT and nZVI-contaminated soil. Therefore, Panicum maximum in the transplantation method should be selected as a hyperaccumulated plant for nano-phytoremediation potting tests. Maximum tolerance dosage of Panicum maximum to TNT-concentration soil was 320 mg/kg and nZVI-contaminated soil was 1000 mg/kg in the transplantation method.
本研究旨在比较涉及发芽和移植的植物修复初始方法。本研究还旨在确定 Panicum maximum（紫色玉米草）和 Helianthus annuus（向日葵）在 TNT 污染土壤和 nZVI 污染土壤中的耐受效率。结果发现，与发芽相比，Panicum maximum 和 Helianthus annuus 的移植更适合作为纳米植物修复盆栽试验的起始方法。研究还表明，在 TNT 和 nZVI 污染土壤中，Panicum maximum 比 Helianthus annuus 更具耐受性。因此，在移植方法中，应选择 Panicum maximum 作为纳米植物修复盆栽试验的超积累植物。在移植方法中，Panicum maximum 对 TNT 浓度土壤的最大耐受剂量为 320mg/kg，对 nZVI 污染土壤的最大耐受剂量为 1000mg/kg。
