The objective of this experiment was to evaluate the effects of Triton X-100 (1000 mg kg) and nano-SiO (500 mg kg) on Erigeron annuus (L.) Pers. grown in phenanthrene spiked soil (150 mg kg) for 60 days. Results show that untreated groups, groups treated with both Triton X-100 and nano-SiO, exhibited better phenanthrene degradation rates and improved root biomasses, chlorophyll contents, and soil enzyme activities. This study demonstrates that Triton X-100 combined with nano-SiO protects plants, alleviating the stress of polycyclic aromatic hydrocarbons (PAHs), and can provide a means for improving phytoremediation of PAH contaminated soils.
本实验旨在评估 Triton X-100（1000mgkg）和纳米 SiO（500mgkg）对在含芘土壤（150mgkg）中生长的 60 天的苍耳（L.）的影响。结果表明，未处理组、同时用 Triton X-100 和纳米 SiO 处理的组表现出更好的芘降解率和提高的根生物量、叶绿素含量和土壤酶活性。本研究表明，Triton X-100 与纳米 SiO 结合保护植物，减轻多环芳烃（PAHs）的胁迫，可为改善 PAH 污染土壤的植物修复提供一种手段。
