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。
Industrial pollution emitted by the harmful gases to the atmosphere, not only affect human health, but also affect the plant area of the plant growth. Different plant species, the reaction of harmful gases are not the same. Through testing, a group of plants that have strong resistance to harmful gases are selected to green the industrial and mining areas, which not only can maintain the landscaping but also appropriately reduce the harm of air pollution. Scientific testing programs for screening resistant plants include: site surveys, smog tests, field pot experiments and field observations. The purpose of the ground planted observation is to obtain the test data of the plant’s resistance and greening effects under the conditions of low concentration, long-term and high concentration, short-term air pollution.
