【摘要】 选用8种常用室内观赏植物,将盆土与茎叶部分隔开,放入自行研制的甲醛熏气箱中,对植物进行熏气试验,测得熏气前后甲醛的变化量和植物叶面积,以单位叶面积甲醛减少量来比较8种植物吸收甲醛能力的大小。结果表明:甲醛质量浓度是国际标准10～15倍情况下,8种观赏植物均能吸收空气中的甲醛,但因种类不同吸收能力大小不一。吸收甲醛能力排序为:橡皮树>海芋>一叶兰>银皇后>马拉巴栗>散尾葵>红掌>孔雀竹芋。单位叶面积植物吸收甲醛量依次为:橡皮树>海芋>一叶兰>马拉巴栗>银皇后>散尾葵>红掌>孔雀竹芋。甲醛质量浓度是国际标准50～60倍情况下,8种观赏植物吸收甲醛能力排序为:一叶兰>银皇后>海芋>马拉巴栗>橡皮树>散尾葵>红掌>孔雀竹芋。单位叶面积植物吸收甲醛量依次为:一叶兰>马拉巴栗>海芋>橡皮树>银皇后>红掌>孔雀竹芋>散尾葵。根据单位叶面积吸收甲醛量的差异,将植物的吸收能力分为2类,吸收甲醛能力较强的植物有:一叶兰、马拉巴栗、海芋、橡皮树、银皇后(与空白组相比有显著性差异(P<0.05));较低的植物有:红掌、孔雀竹芋、散尾葵(与空白组相比无显著性差异)。更多还原

【Abstract】 This paper has chosen eight species of indoor ornamental plants.Pot and soil were separated from the haulm and put into a self-designed fumigating box to conduct a fumigating experiment.We measured the change of formaldehyde and the plant leaf area before and after the fumigating.Also we compared the ability of the eight plants to absorb formaldehyde based on the reduction of formaldehyde in the unit leaf area.The results showed that if the mass concentration of formaldehyde was 10～15 times as high as the international standard(0.08 mg/m~3),all the eight kinds of ornamental plants can absorb formaldehyde in the air,but their absorption capacity varies with each kind.Their absorption capacity was as follows:Ficus elastica>Alocasia macrorrhizos>Aspidistra elatior>Aglaonema commulatum cv.Silver Queen>Pachira aquatica>Chrysalidocarpus lutescens>Anthurium andraeanum>Calathea makoyana.The absorption efficiency of the formaldehyde amount per unit of leaf area was as follows:Ficus elastica>Alocasia macrorrhizos>Aspidistra elatior>Pachira aquatica>Aglaonema commulatum cv.Silver Queen>Chrysalidocarpus lutescens>Anthurium andraeanum>Calathea makoyana.If the mass concentration of formaldehyde was 50～60 times as high as the international standard,their absorption capacity was as follows:Aspidistra elatior>Aglaonema commulatum cv.Silver Queen>Alocasia macrorrhizos>Pachira aquatica>Ficus elastica>Chrysalidocarpus lutescens>Anthurium andraeanum>Calathea makoyana.The absorption capacity of the formaldehyde amount per unit of leaf area was as follows:Aspidistra elatior>Pachira aquatica>Alocasia macrorrhizos>Ficus elastica>Aglaonema commulatum cv.Silver Queen>Anthurium andraeanum>Calatheamakoyana>Chrysalidocarpus lutescens. According to the absorption capacity of the formaldehyde amount perunit of leaf area,the absorption capacity of the plants falls into two categories:the plants that absorb more formaldehyde include:Aspidistra elatior,Pachira aquatica, Alocasia macrorrhizos,Ficus elastica,Aglaonema commulatum cv.Silver Queen(There was a striking difference when compared to the blank group(P<0.05));those which absorb less formaldehyde include:Anthurium andraeanum, Calathea makoyana,Chrysalidocarpus lutescens(There was no striking difference when compared to the blank group).更多还原
