摘要： 采用盆栽试验,研究短毛蓼对不同浓度锰污染土壤的耐性和富集效应,并施加不同浓度抗坏血酸对短毛蓼的修复效果进行强化研究。结果表明:短毛蓼对锰表现出很强的耐性,在锰添加浓度为2 000 mg·kg-1时短毛蓼仍然能正常生长;随着锰添加水平的提高,地上部分和地下部分的锰含量都显著增加。添加抗坏血酸可以使短毛蓼的耐锰性提高,在锰添加量为5 000 mg·kg-1时仍能存活;添加较低浓度抗坏血酸可以显著增加短毛蓼的锰迁移量。

关键词: 短毛蓼, 锰, 植物修复, 抗坏血酸

Abstract: Pot experiment was used to study the Mn tolerance andaccumulation of Polygonum pubescens Blume under different Mn concentrationsin soil.On the other hand,ascorbic acid was added into the Mn-contaminated to investigate its influence on the remediation effect of the soil by the plant.Theresults indicated that the Polygonum pubescens Blume showed certain toleranceto the Mn-contaminated soil.The plant still grew well when Mn concentration was2 000 mg·kg-1.With the Mn concentration in the soil increasing,the manganese concentration in the tissues of the plant increased.Adding ascorbic acid can improve the tolerance of the plant so that they can be still alive when the Mnconcentration was 5 000 mg·kg-1.Adding ascorbic acid of lower concentration can increase the Mn translocation amount of Polygonum pubescens Blume from the Mn-contaminated soil,but higher concentration showed restrictive effect.

Key words: Polygonum pubescens Blume, Mn, phytoremediation, ascorbic acid
