| 摘 要： | 测定了郑州市的5种园林植物叶面颗粒物附着密度,利用扫描电镜观察比较了各测试树种叶表面微形态.结果表明,颗粒物附着密度在不同树种之间存在差异,各植物叶片颗粒物附着密度由高到低依次是海仙花>枇杷>广玉兰>垂柳>女贞.大气颗粒物主要附着在叶片上表面,叶片表面滞留大气颗粒物能力由高到低的微形态结构依次是绒毛>沟槽>小室>条状突起.这些微形态结构越密集、深浅差别越大,越有利于滞留大气颗粒物.深度清洗后叶片表面仍能滞留小粒径的颗粒物. |
| 关 键 词： | 园林植物 大气颗粒物 叶表面 微形态 |

| Abstract: | With five garden plant species in Zhengzhou City as test materials,the adhesion density of atmospheric particles on leaf surface is tested and the micro-configurations of leaf epidermis are observed through scanning eletron microscope(SEM).The results showed that the adhesion densities of atmospheric particles in five researching plants were significantly different,and the adhesion densities of particles in the atmosphere decreased in the order of Weigela coraeensis > Eriobotrya japonica> Magnolia grandiflo... |
| Keywords: | garden plant atmospheric particles leaf epidermis micro-configurations |
