中文摘要：
为了解渍水对油菜的影响和恢复期油菜养分的变化，采用盆栽试验，研究不同持续时间的渍水对油菜（Brassica napus L.）品种中双11号苗期生长及养分吸收的影响。结果表明，渍水对苗期生长的不利影响不仅在于渍水期间，还在于渍水后生长恢复所需的时间。随渍水时间延长，叶片氮（N）、磷（P）、钾（K）、铁（Fe）、锌（Zn）、铜（Cu）含量显著降低，锰（Mn）含量显著升高；根系N、Fe、Zn、Cu含量显著升高，P含量显著降低，Mn含量3d时显著升高之后显著降低，而K含量没有显著变化。渍水使土壤中硝态氮与铵态氮的比例显著降低；速效P含量显著降低；速效K和有效态Fe、Zn含量出现先升高后降低的波动；有效态Cu在渍水期间没有显著变化，渍水后显著降低。
英文摘要：
To understand the nutrient uptaking during and after the waterlogging stress, a pot experiment was conducted to investigate the effects of different waterlogging durations on rapeseed growth and recovery using Brassi- ca napus L. cv Zhongshuang 11. Results showed that the adverse effect of waterlogging on oilseed rape seedling was not only on growth during stress, but also on recovery period after flooding. The leaf nitrogen （N）, phosphorus （ P）, potassium （ K）, iron （Fe）, zinc （Zn） and copper （Cu） concentrations were significantly decreased, but the leaf manganese （Mn） concentration was significantly increased with the period of waterlogging lasted. The root N, Fe, Zn, and Cu concentrations were significantly increased, the root P concentration was significantly de- creased, the root Mn concentration was significantly increased at 3d then significantly decreased, and the root K concentration was no significantly different during waterlogging. Moreover, in soils, the proportion of nitrate to am- monium and available P concentration were both significantly decreased. Available K, Fe and Zn concentrations were curved. Cu concentration in soils was no significantly different during waterlogging but significantly decreased after.
