摘要
比较了吉林省吉林市10种宿根花卉不同季节和不同时间的滞尘能力。结果表明,不同植物单位叶面积滞尘量有差异,芍药(Paeonia lactiflora Pall.)、玉簪[(Hosta plantaginea(Lam.)Aschers)]、马蔺(Irisensata Thunb)和黑心菊(Rudbeckia hirta L.)滞尘能力较强,总体上同种植物滞尘能力夏季大于春季;在达到饱和之前,随时间的延长,滞尘量随单位叶面积的增加而增长,雨后第10天滞尘量对总滞尘量的贡献最大,雨后14 d达到饱和。
The dust retention capacities of 10 perennial root flower plants in different seasons and times in Jilin were compared. Results showed there were differences between the dust reduce quantity of different greening tree species. The stronger dust-blocking effect were Paeonia lactiflora Pall, Hosta plantaginea（Lam.） Aschers, Irisensata Thunb and Rudbeckia hirta L.. Overall, the dust detaining abilities of the same tree species in the summer was stronger than that in spring. Before the saturation of the dust detaining ability, the amount of dust increased with the increase of the unit leaf area. The amount of dust retention in 10th day after the rain was the biggest. It reached saturation in 14th after the rain.
