Study on the Anti-acid rain Ability of Landscape Plants in Nanping

FANG Zhiwei(Foretry Colloge of Fujian Agriculture and Forestry University,Nanping 353001,China)  

Simulated experiments were made for 18 common gardens plants of southern China under the condition of different pH The results show that: 1) The effects caused by acid rain of different concentration on different species were different The lower the pH is,the more serious damage it will causeBut these species have better fastness against the acid rain of above pH352) According to their fastness the order is:Ilex cornutaPittpsporum tobiraCryptomeria \{fortune\}Podocarpus nagiPodocarpus macrophyllusTrachycarpus fortuneiBambusa ventricosaMagnolia liliflora DesrOsmanthus fragransBauhinia purpure Michelia figoJasminum nudiflorumOphiopogon bodinieri LevlAcer palmatumLantana camaraRhododendron simsiiPunica grannatumMurraya paniculata 3) The rules of symptoms of the injured species are different Some species change dramatically,such as Michelia figo,Rhododendron simsii Podocarpus macrophyllus Some species such as Magnolia liliflora Desr show a little symptom at first,but after some time,they become worse Some species,for example Jasminum nudiflorum,Lantana camara L.injured,Murraya paniculata,Bauhinia purpurea,Ophiopogon bodinieri Levl damage to a large extend in short time But to the species of Ilex cornuta, Pittpsporum tobira,Podocarpus nagiagrans,the changes are very slow and the symptoms will be shown after a long time.
