摘要
在自行设计的密闭玻璃箱内,采用熏蒸方法,用浓度分别为0.39、0.47 mg/m3的甲醛对吊兰、常春藤、豆瓣绿、绿萝、龟背竹、袖珍椰子等6种室内观赏盆栽植物熏蒸24 h,比较这6种植物的甲醛净化效果。结果表明:6种植物均具有净化甲醛的能力,在0.47 mg/m3甲醛浓度下,6种植物整体盆栽对甲醛的去除率达33%,高于盆栽地上部分的去除率(14.7%)。6种植物整体盆栽对甲醛去除率从高到低依次为龟背竹、袖珍椰子>吊兰>绿萝>豆瓣绿>常春藤;植物盆栽地上部分对甲醛去除率从高到低依次为龟背竹>豆瓣绿>常春藤>袖珍椰子>绿萝>吊兰。盆栽土壤微生物对甲醛去除最强的是绿萝和袖珍椰子,盆栽消毒土壤对甲醛去除最强的是吊兰。
In a self-designed airtight glass box, this research compares the effect on purifying formaldehyde of six kinds of indoor ornamental plants including Chlorophytum comosum (Thunb.) Baker, Hedera nepalensis K, Koch var. sinensis (Tobl.) Rehd., Peperomia tetraphyUa (Forst. F.) Hooker et Arnott, Scindapsus aureus (Linden et Andre) Bunting, Monstera deliciosa Liebm, Chanu^dorea elegans Mart by fumigation method for 24 hours. The concentration of formaldehyde is 0.39 mg/m3 and 0.47 mg/m3. The results show that the six kinds of plants all have different levels of decontamination. When the concentration of formaldehyde is 0.47 mg/m3, the plants can remove 33% formaldehyde while the removal rate of the plants above ground is 14.7%. The removal rate order of the six plants is M. deliciosa Liehm, C. elegans Mart., C. comosum (Thunb.) Baker, S. aureus (Linden et Andre) Bunting, P. tetraphyUa (Forst. F.) Hooker et Arnott, H. nepalensis K,Koch vat. sinensisi (Tobl.) Rehd., while the removal rate order of the six plants above ground is M. deliciosa Liebm., P. tetraphylla (Forst. F.) Hooker et Arnott, H. nepalensis K,Koch vat. sinensisi (Tobl.) Rehd., C. elegans Mart, S. sanreus (Linden et Andre) Bunting and C. comosum (Thunb.) Baker. Soil microorganisms of S. anreus and C. elegans Mart., and purifying soil of C. comosum (Thunb.) Baker have the strongest ability to remove formaldehyde.
