摘要: 采用2种施硒方式及不同硒浓度对油菜进行处理,测定油菜各部位的干质量及硒与其他元素的含量。结果表明,无论采用何种施硒方式,低浓度(土壤施硒0.1 mg·kg-1或叶面喷施0.1 mg·L-1)的硒有助于提高油菜生物量,而高浓度(土壤施硒1.0 mg·kg-1或叶面喷施0.5 mg·L-1)硒处理均降低了油菜生物量。外源硒增加了油菜根、茎、叶中氮、磷、钾、钙、镁、锰等的含量,以及油菜根中铁含量、叶中铜含量和根、茎中锌含量。外源硒促进了油菜茎中氮、磷、钾、镁、铁、铜、锌向叶的迁移,降低了根中磷、钾、镁、铁、锌向茎的迁移。低浓度硒降低了油菜根中钙向茎的迁移,高浓度硒促进了油菜茎中钙向叶的迁移。

Abstract: In the present study, the effects of two selenium (Se) application methods and different Se concentrations on the dry weight and element contents of rapes were investigated. It was shown that 2 selenium application methods had similar influences on rape. The rape biomass was increased by the lower Se levels (0.1 mg·kg-1 in soil or 0.1 mg·L-1 foliar application), yet was decreased by the higher Se levels (1.0 mg·kg-1 in soil or 0.5 mg·L-1 foliar application). External Se application increased the contents of N, P, K, Ca, Mg, Mn in roots, stems, and leaves, as well as Fe in roots, Cu in leaves and Zn in stems and root. External Se application enhanced the translocation of N, P, K, Mg, Fe, Cu, Zn from stems to leaves, while reduced the translocation of P, K, Mg, Fe, Zn from roots to stems. Se application reduced the translocation of Ca from roots to stems at the lower levels, whereas the translocation of Ca was enhanced from stems to leaves at the higher levels.

Key words: selenium, rape, mineral element, content, translocation characteristic
