在SO2、Cl2污染环境栽培抗性植物的试验研究

<正> 工业生产排放出的有害气体对大气的污染,不但影响人的健康,而且也影响工厂区的植物生长。植物种类不同,对有害气体反应也不一样。通过试验筛选一批对有害气体具有较强抗性的植物,用以绿化工矿区,不仅可保持环境美化,还可以适当减轻大气污染的危害程度。 筛选抗性植物的科学试验程序包括:现场调查,熏气室试验、现场盆栽试验和现场地栽观测。地栽观测的目的在于取得植物在低浓度、长期和高浓度、短期的大气污染条件下的抗性反应和绿化效应的试验资料。

THE CULTIVATED EXPERIMENTS OF RESISTANT PLANTS IN POLLUTION OF SULFUR DIOXIDE AND CHLORINE

The cultivated experiments of resistant plants were carried out from 1974 to 1980 in factories polluted by industrial sulfur dioxide (SO2) and chlorine (Cl2), 50 species of plants were tested.As the result, more than 30 species were selected as the resistant plants which were adapted for growing in factories polluted by SO2 and Cl2, such as Ficus altissima, F. drupacea var. glabrata, Hibiscus tilaceus, Mimusops elengi, Mangifera indica, Ficus virens var. sublanceolata,,Syzygium jambos, Aleurites moluccana, Nerium indicum, etc.This study showed that the cultivated experiments through a long period of time in polluted environments were the important means for estimating the resistance of plants and were the final step of the Experimental procedure.
