- 摘要:
- 以大戟科、桑科、五加科13种室内盆栽植物为试验材料，分别置于体积为1.0 m×1.0 m×0.8 m密封玻璃用箱内，甲醛起始浓度均设置为15 mg/m3，连续观察7 d，测定叶片叶绿素含量、细胞膜透性、干物质、甲醛含量，研究其对甲醛的净化作用。结果表明：福禄桐对甲醛抗性强（0级）；常春藤、鸭脚木、变叶木抗性较强（Ⅰ级）；南洋森、细叶榕、一品红抗性中等（Ⅱ级）；红雀珊瑚、玉麒麟、星点变叶木、柳叶榕抗性较差（Ⅲ级）；抗性最差（Ⅳ级）是橡皮树、圆叶福禄桐。甲醛处理后，密封玻璃箱内甲醛浓度均呈递减变化，递减最快都集中在试验后1~3 d。对甲醛处理产生伤害反应少或较少，而吸收能力强的前5种植物是：常春藤、鸭脚木、一品红、柳叶榕、福禄桐，可作为甲醛净化专用植物应用推广。
- Abstract:
- Thirteen plant species from Euphorbiaceae，Moraceae and Araliaceae families were tested for their abilities of removing formaldehyde (FDH) in the air.Each plant was placed for seven days in a 1.0 m×1.0 m×0.8 m glass box filled with formaldehyde with the initial concentration of 15 mg/m3，determination of chlorophyll content，cell membrane permeability，dry matter，formaldehyde content,purification of formaldehyde-polluted air by several potted plants were studied.The results showed the top resistance of Polyscias balfouriana to formaldehyde pollution damage；some plants such as Hedera nepalensis,Schefflera octophylla showed the secondary resistance ability to FDH；other plants such as Polyscias fruticosa, Ficus microcarpa, Euphorbia pulcherrima showed the three levels resistance ability；plants such as Pedilanthus tithymaloides, Euphorbia neriifolia var.cristata，Codiaeum variegatum，Ficus benjamina showed the four levels resistance ability.Ficus elastica and Polyscias balfouriana showed no resistance to FDH.The absorption of plants for FDH in the glass chamber was found especially apparent different during the first three days.In conclusion，5 species of the potted plants which could be recommendable to be used for FDH purification were Hedera nepalensis, Schefflera octophylla，Euphorbia pulcherrima，Ficus benjamina,?Polyscias guifoylei.These plants had a high absorption ability to FDH and had less damage.
