摘要
在实验室人工控制条件下，研究了不同浓度土壤石油污染对两种藜科植物幼苗生长的影响。实验结果表明：土壤石油污染质量分数为500—5000mg／kg时，对碱蓬幼苗株高的生长有一定的促进作用，土壤石油污染质量分数在15000～30000mg／kg时有显著的抑制作用；任何浓度的土壤石油污染都会抑制翅碱蓬幼苗株高的生长，随着石油浓度的逐级增加，抑制作用逐级增大。
Effects of petroleum pollution at different concentrations on seedling growth of two kinds of chenopodiaceae plant under artificially controlled in laboratory was studied. The results showed that the petroleum would promote the height of seedling of Salsola glauca Bunge when the mass fraction of oil-contaminated soil was the 500 5000mg/kg while the petroleum would remarkably restrain it when the mass fraction of oil - contaminated soil was at 15000 -30000mg/kg ; Any concentration of oil-contaminated soil would restrain the growth of seedling of Salsola hetroptera Kity, With the level of oil concentration increasing, the level of restraint would increase.
