以竹芋科和蕨类室内盆栽植物各10种为试验材料,分别置于体积为1.0m×1.0m×0.8m密封玻璃箱内,甲醛起始浓度均设置为15mg/m3,连续观察7d。结果表明:卷叶巢蕨(Neottopteris nidus cv.Volulum)、矩叶肖竹芋(Calathea lubbersiana)对甲醛抗性最强(Ⅰ级);银线竹芋(C.ornata)、银羽斑竹芋(C.setosa)、翠叶竹芋(C.freddy)和彩虹竹芋(C.roseo-picta)抗性较强(Ⅱ级);巢蕨(N.nidus)、傅氏凤尾蕨(Pteris fauriei)、银脉凤尾蕨(P.ensiformis cv.Victoriae)、银心大叶凤尾蕨(P.cretica cv.Albolineata)、肾蕨(Nephrolepis cordifolia)、华南毛蕨(Cyclosorus parasiticus)、乌毛蕨(Blechnum orientale)、花叶竹芋(Maranta bicolor)和天鹅绒竹芋(C.zebrina)抗性最差(Ⅳ级)。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1～3d之间。吸收甲醛最快的植物是天鹅绒竹芋和星蕨(Microsorum punctatum),最慢的是华南毛蕨、银脉凤尾蕨、卷叶巢蕨和银羽斑竹芋。对甲醛处理产生伤害反应少或较少,而吸收能力强的前8种植物是:巢蕨、青苹果竹芋(C.rotundifolia)、银心大叶凤尾蕨、银线竹芋、二歧鹿角蕨(Platycerium bifurcatum)、卷叶巢蕨、彩虹竹芋和翠叶竹芋,可作为甲醛净化专用植物应用推广。
10 species of Potraceae and Pteridophyte were used as test materials and placed in sealed glass boxes of 1.0m × 1.0m × 0.8m in volume respectively. The initial concentration of formaldehyde was set at 15mg / m3 for 7 days. The results showed that Neottopteris nidus cv. Fuller and Calathea lubbersiana had the strongest formaldehyde resistance (Grade Ⅰ), C.ornata, C.setosa, C.freddy and C.roseo-picta (Grade Ⅱ), N.nidus, Pteris fauriei , P. flexiformis cv. Victoriaiae, P.cretica cv. Albolineata, Nephrolepis cordifolia, Cyclosorus parasiticus, Blechnum orientale, Maranta bicolor, and C. zebrina (Grade IV). After formaldehyde treatment, the concentration of formaldehyde in the sealed glass box showed a decreasing change, the fastest decreasing concentrated in the test after 1 ~ 3d. The fastest formaldehyde-absorbing plants are Microsorum punctatum and the slowest species are Southern China fern, Yinfeng Pteridopteris, Coccinella septempunctata and Agla platyphylla. Formaldehyde treatment harm less or less, while the absorption capacity of the top 8 plants are: nectar, green apple taro (C.rotundifolia), silver heart Pteridophyta, silver line arrowroot, two Antler fern (Platycerium bifurcatum), leaf roller nest fern, rainbow arrowroot and Cui leaf arrowroot, formaldehyde can be used as a dedicated plant purification applications.
