4种植物吸收甲醛能力分析

以红豆杉、美人蕉、八角金盘、茉莉等4种植物为研究对象，通过人工模拟环境，在3种不同甲醛浓度下探讨4种植物吸收甲醛的能力。结果表明：4种植物对甲醛均有较好的吸收能力；综合考虑12 h内3种浓度下整个植株的吸收率，红豆杉的吸收效果最好，美人蕉和八角金盘次之，茉莉的吸收效果最差；4种植物单位叶面积吸收量随甲醛浓度的增大而增大，高浓度下美人蕉的单位叶面积吸收量最大，其吸收能力最强。

Study on Formaldehyde Absorption Capacity of Four Plant Species

The formaldehyde absorption capacity of four plant species, i.e.,Taxus chinensis, Canna indica, Fatsia japonica and Jasminum sambac was studied with a sealed chamber of boilerplate by three formaldehyde concentrations. The results showed that all the four plant species had a pretty good absorption capacity to formaldehyde. By comparing the absorption rate of formaldehyde with 3 different concentrations in 12 hours, Taxus chinensis was the best, followed by Canna indica and Fatsia japonica, the formaldehyde absorption rate of Jasminum sambac was the weakest. The formaldehyde absorption amount per unit leaf area was increased along with the concentration increment. Under high formaldehyde concentration, the absorption amount per unit leaf area of Canna indica was the highest, indicating the formaldehyde absorption capacity of Canna indica was the strongest among the four plant species.
