不同盆栽基质对净化甲醛效果的影响

Effect of Purifying Indoor Formaldehyde Pollution of Different Cultivated Substrates

以4种盆栽基质组合为试材,采用气体密封舱熏气法,进行甲醛熏气处理,以净吸收率来比较盆栽基质吸收甲醛能力的大小,为净化室内甲醛污染筛选出适合的植物盆栽基质。结果表明:被测盆栽基质在一定程度上均可以有效吸收甲醛,在种植前其吸收甲醛的能力从大到小依次为硅藻土、草炭、树皮、锯木屑,而在种植后其吸收甲醛的能力从大到小依次为硅藻土、树皮、草炭、锯木屑,综合分析表明,4种盆栽基质均适合室内净化甲醛空气污染植物的应用,特别是硅藻土、树皮、草炭等,值得推广。

To select suitable cultivated substrates for use in purified indoor formaldehyde pollution, 4 kinds of substrates were evaluated for their effectiveness in reducing formaldehyde concentrations in a simulated fumigating box environment ,and the absorption capacities were compared and ranked according to the net ratio of absorption. The results showed that the capacities of different substrates in removing formaldehyde were different, and the order of the substrates according to the absorption efficiency amount before planted was diatomite〉peat〉bark〉sawdust, the order of the substrates according to the absorption efficiency amount after planted 30 days was diatomite〉bark〉peat〉,sawdust. According to formaldehyde removal capacity in the experiment, the four different substrates were suitable for use in purified indoor formaldehyde pollution,especially diatomite,bark and peat.
