摘要
对大气氟污染与观赏植物牡丹叶片中的含氟量之间的关系进行了分析。结果表明 :( 1 )一定时间内牡丹叶片的吸氟量和积累量成正相关。 ( 2 )牡丹叶片中的含氟量与测定点距污染源的距离呈负相关。 ( 3 )牡丹叶尖枯病是因大气氟污染所致 。
The relationship between air fluoride pollution and the fluoride content in ornamental peony foliage was analysed.The results show that the obtaining and accumulation of fluoride in peony foliage in a certain period are positively related while the fluoride content is negatively related to the distance between inspection spot and the source of fluoride pollution;that peony leaf tip blight is caused by air fluoride pollution but not by pathological changes.
