| 中文摘要: |
| 为探求不同土壤水分和镉浓度对油菜生长生理特性及产量的影响，设置3个土壤水分处理组（相对含水量70%~80%、60%~70%和50%~60%），每个水分处理下分别设置6个镉处理浓度（0、5、10、15、20、30 mg·kg-1），共18个处理。测定不同水分及镉处理对油菜生长、生物量、光合参数及产量的影响。结果表明：土壤水分的增加，对油菜株高、生物量、光合作用和产量有明显的促进作用；在供试镉浓度处理下，油菜生长生理及产量指标并无显著性差异，表明油菜对镉具有较好的耐受性。 |
| 英文摘要: |
| In this paper, the rape(Brassica junica) was used as test materials, and two factors including water content and cadmium stress were tested, comprising three water treatments(70%~80%、60%~70% and 50%~60% of relative moisture content) and six cadmium treatments(0、5、10、15、20、30 mg·kg-1), to find out the effects of different soil moisture and cadmium concentrations on physiological characteristics and yield of rape. The results showed that with the increase of soil water content, the plant height, biomass, photosynthesis and yield of rape were significantly promoted; Under the tested Cd concentrations, there were no significant difference in rape growth physiology and yield index, which indicating that rape had a certain resistance to cadmium in cadmium contaminated soil. |
