摘要
通过盆栽试验,研究了石油污染物在不同土壤类型上对小白菜生物量和VC、总糖含量等品质指标的影响。结果表明:在3种土壤上石油污染物对小白菜产量和品质的影响表现一致,石油污染物浓度为500 mg/kg时,可以促进小白菜的生长,表现为产量、株高增加,对小白菜的品质影响也很小,但是当浓度超过500 mg/kg时,随着浓度的加大,对小白菜的抑制作用就越来越明显,小白菜产量和品质开始下降。
By pot experiment, the effect of petroleum pollutant on rape biomass and contents of Vc and total sugar were studied. The results showed that 500 mg/kg petroleum pollutant could promote the rape growth which performed as increasing the yield and plant height, and also had little effect on rape quality. But when the concentration of the petroleum pollutant was over 500 mg/kg, the rape yield and quality began to decrease with the increase of the petroleum pollutant concentration.
