绿色植物对净化空气,保护和改善环境有积极的作用。许多高等植物具有抵抗和吸收有毒气体的能力,但各种植物对有毒气体的抵抗能力是不同的。为了选择出能抵抗和吸收有毒气体的树种,1973年我们就开始进行调查研究和对比筛选工作,对几十种绿化树种的抗毒能力有了概括的了解,现简介如下。一抗有毒气体树种的选择选择抗有毒气体的树种主要可通过以下几种办法:(一)对工厂污染区现有绿化树种的生长情况进行调查,比较其抗性强弱:在某些经常散发有毒气体的工厂附近,各种树
Green plants play a positive role in purifying the air, protecting and improving the environment. Many higher plants have the ability to resist and absorb toxic gases, but the resistance of various plants to toxic gases is different. In order to select the species that can resist and absorb toxic gases, we started the investigation and comparative screening work in 1973 and gave a general understanding of the anti-virus ability of dozens of greening species. The brief introduction is as follows. The selection of primary toxic gas species The choice of anti-toxic gas species mainly through the following ways: (a) of the existing contaminated area plant greening species to investigate the growth of the situation, compared its resistance: In some often distributed Toxic gas near the plant, various trees
