摘要:
本文通过油菜盆栽试验,研究了山东三大类型土壤上石油污染物对油菜产量和叶绿素含量、POD、硝酸还原酶活性、根活力、细胞膜透性等一系列生理指标的影响。研究结果表明:不同土壤类型油菜的生长受石油污染物影响的程度不同,其中棕壤土上油菜生长受土壤石油烃含量的变化影响较小,对石油烃造成的影响修复能力较强,油菜长势最好产量最高。不同石油烃含量对油菜生长的影响也不同,当石油烃含量为500 mg/kg时,与空白处理相比,油菜产量有所增加,但随石油烃含量继续增大,对油菜的影响也越明显,表现为油菜产量、叶绿素含量、根活力、硝酸还原酶活性大幅降低,细胞膜透性和POD大大增加。

Abstract: By rape pot experiment, rape response of three-type soils in Shandong Province to incorporation of oily sludge was studied. Rape biomass and physiologic indices included yield, chlorophyll content, POD, NR activity, root vigor and cell membrane permeability. The results showed that effects of oil-pollution on rape were varied with different soil types. The effect of petroleum hydrocarbon on rape growth in brown soil was lightest. The ability to repair for oily sludge was stronger in brown soil. Rape growth was best and yield was highest. Effects on rape growth were varied with petroleum hydrocarbon content. Petroleum hydrocarbon could promote rape growth when the consistency was 500 mg/kg. It increased rape yield. But when the petroleum hydrocarbon consistency > 500 mg/kg, the harm of rape was more serious. It was shown that rape yield was decreased. Chlorophyll content and root activity and NR activity reduced gradually with the increase of petroleum hydrocarbon consistency. Cell permeability and POD activity increased rapidly with the increase of petroleum hydrocarbon consistency.
