不同的植物,在不同的环境条件下,抗氯和吸氯的能力各不相同。本文以桂林市常见绿化植物为材料,用自己设计的开顶式熏气装置进行试验,观察植物受氯污染时的反应症状,根据症状的有无和轻重程度,划分植物的抗性等级。此外,以氯污染区生长正常的植物叶片含氯量减去相对清洁区植物叶片含氯量(相对基数值),称为植物叶片正常吸氯净化量;以植物受到严重氯污染以致叶片枯死脱落时的含氯量减去正常吸氯净化量,称为植物叶片非常净化量,借以表示植物在氯污染非常严重的情况下所能发挥的最大净化潜力。
Different plants, in different environmental conditions, the ability to resist chlorine and chlorine vary. In this paper, the common greening plants in Guilin as materials, with their own design open-top fumigation devices were tested to observe the reaction symptoms of plants contaminated with chlorine, according to the presence of symptoms and severity of plant resistance levels. In addition, the chlorophyll content of chlorophyll in plants with normal growth of chlorine minus the chlorophyll content (relative base value) of plant leaves in relatively clean area is called the normal chlorination amount of chlorophyll in plant leaves; When the chlorine content minus the normal amount of chlorine purification, known as the very purification of plant leaves, in order to indicate the plant in the case of chlorine pollution can play a very serious potential maximum purification.
