7种植物对室内甲醛净化能力的比较

以橡皮树(Ficus elastica)、龟背竹(Monstera deliciosa)、白玉黛粉叶(Diffenbachia'Camille')、金边竹蕉(Dracaena deremensis'Roehrs Gold')、芦荟(Aloe arborescens var.natalensis)、麒麟掌(Eephorbia neriifolia var.cristata)、中斑吊兰(Chlorophytumcomosum'Vittatum')为材料,采用人工模拟熏气方法,测定其在0.32 mg·m-3、0.89 mg·m-3甲醛污染24 h后,对甲醛的吸收效果,及自身电导率、叶绿素含量、超氧化物歧化酶活性的变化。结果表明:随着甲醛气体浓度的升高,植物对甲醛气体的吸收率都呈下降趋势。当甲醛为0.32 mg·m-3时,对植物内部生理影响非常小;当甲醛为0.89 mg·m-3时,对植物内部生理影响很大。

The Comparison of the Indoor Formaldehyde Decontamination Ability of 7 Plants

Seven indoor plants:Ficus elastica,Monstera deliciosa,Diffenbachia ′camille′,Dracaena deremensis ′Roehrs Gold′,Aloe arborescens var.natalensis,Eephorbia neriifolia var.Cristata,Chlorophytum comosum ′Vittatum′ were measured by simulation experiments and evaluated with artificial simulation fumigation method for the ability of removal of formaldehyde after 24 hours long pollution of 0.32 mg·m-3 and 0.89 mg·m-3 of formaldehyde.At the same time it had surveyed the change of the plants' physiology index sign,such as electric conductivity rate,chlorophyll content,and SOD activity.The result showed:the plants presented a drop tendency to the formaldehyde gas clearance percentage.with formaldehyde gas density elevating,.Under the condition of the formaldehyde density of 0.32 mg·m-3,all physiology plant index varieties were all very small.Under the condition of the formaldehyde density of 0.89 mg·m-3,all physiology plant index varieties were all very large.
