摘要
采用盆栽试验法探讨了华北油田石油污染土壤上玉米（Zea mays）和小麦（Triticum aestivum）在不同石油污染物浓度下的发芽率、株高、生物量及其对石油污染物的清除效率。结果表明，在0～60g/kg的石油污染物浓度范围内，玉米的发芽率均高达80％以上，并且其株高和生物量受石油污染物的影响相对较小；在10～30g/kg 的范围内，玉米（70日龄）的除油率均达到40％以上。小麦在浓度10～30g/kg范围内发芽率较高，但随着污染物浓度的升高发芽率急剧下降，株高和生物量亦相应降低。与小麦相比，玉米对石油污染的耐受性更强。
The germination rate,plant height,biomass and petroleum removal efficiency of maize and wheat in different oil concentration of soil pollution in Huabei Oilfield were studied by using the method of a pot experiment.The results showed that the germination rate of maize were more than 80%in 0~60g/kg of oil pollutants concentration range,and oil removal rate of maize(70dof age)was more than 40%in 10~30g/kg range.Germination rate of wheat is higher in the concentration of 10~30g/kg range,while fell sharply with the increase of concentration,and plant height and biomass also reduced correspondingly.Tolerance of maize to oil pollution is stronger compared with that of wheat.
