- 摘要：石油污染土壤的植物修复技术以其处理成本低、无二次污染、自然美观等特点,正逐步成为石油污染治理研究的一个重要方向.而修复植物的筛选是植物修复技术首要解决的问题.为此以花卉植物种子发芽作为生态指示,探讨其对石油污染土壤的反应,设置了4组不同浓度的石油污染土壤处理,对8种供试花卉植物的种子发芽率进行了盆栽实验观测.结果表明:不同的花卉种子对石油污染表现出不同的耐受性,与清洁对照土壤相比,大多数花卉种子的萌发都明显受到石油烃污染的抑制,其中受石油烃污染影响最严重的是二月兰(Orychophragmus violace).相比之下,4组浓度处理下硫华菊(Cosmos sulphureus)和孔雀草(Tagetes patula)具有较高的耐受性和种子发芽率,因而具有修复石油污染土壤的潜力.
- Abstract：The phytoremediation technique of petroleum contaminated soils is becoming an important research direction in petroleum contamination treatment due to its low cost,avoidance of secondary contamination and natural beautification.Screening of appropriate plants for remediation is the key question which must first be solved in phytoremediation.Using seed germination as an ecological indicator,the germination of 8 ornamental seeds planted in contaminated soils were observed at 4 pollution concentration levels.The results showed that these ornamental seeds had significantly different responses to petroleum pollution.Compared with those planted in clean soils,the germination of most ornamental seeds planted in the contaminated soils was obviously inhibited.February orchid(Orychophragmus violace)was the ornamental affected most adversely.Fortunately,strong endurance and high seed germination were observed for Cosmos sulphureus and Tagetes patula under 4 different levels of petroleum pollution,thus displaying the potential of remedying petroleum contaminated soils.
