为了解植物对PM2.5的净化作用,设计了一种玻璃试验箱,以微型汽油机尾气为PM2.5源,应用CASELLA CEL-712 Microdust Pro实时粉尘监测仪,测定了杜鹃、金边大叶黄杨、月月桂、红檵木、八角金盘5种常用园林绿化植物对PM2.5的净化作用。结果表明:植物对以汽油燃烧的尾气中的PM2.5有明显的净化作用。在试验箱内,经过8个小时左右的净化,空气质量可达到国家一级（优）标准。不同植物对PM2.5的净化作用差异较大,供试的5种植物中,单位叶面积净化能力从强到弱依次为:红檵木>杜鹃>月月桂>八角金盘>金边大叶黄杨。高浓度PM2.5在短时间内对这5种植物的外部形态没有造成伤害。

In order to understand the purifying effect of the plant on PM2.5, a glass test chamber was designed. The micro-gasoline engine tail gas was used as PM2.5 source, and GASELLA CEL-712 Microdust Pro real-time dust monitor was used to measure the purification of PM2.5 by five kinds of landscaping plants as Rhododendron simsii, Euonymus japonicus var. aurea-marginatus, Osmanthus fragrans var. semperflorens, Loropetalum chinense var. rubrum, and Fatsia japonica. The results showed that the plant had obvious purifying effect on PM2.5. In the test box...
