| 摘 要： | 通过土培试验测定了不同浓度芘处理下小白菜根和茎叶的生物量、芘及其它矿质元素的含量和一些营养品质指标。结果表明:芘对小白菜根干重的影响显著,对茎叶干重和株高的影响不显著,全株干重由于根干重的下降而呈下降趋势;根中的芘含量和土壤中残留的芘含量随土壤中芘浓度增加而显著增加,茎叶芘含量与对照无显著差异,土壤芘降解率随芘浓度增加表现为先上升再下降的趋势;茎叶有机碳和根粗灰分含量随土壤芘浓度的增加而下降,茎叶粗灰分和根有机碳含量施芘处理显著高于对照,芘促进了根对土壤中N、P、K和S的吸收同化,并加速其向茎叶的转移。茎叶粗蛋白含量较对照有所增加,粗纤维和可溶性糖含量则随芘浓度增加而下降,其中可溶性糖含量各个处理与对照之间的差异达显著水平。
