| 摘 要： | 以甘蓝型油菜品种‘秦优九号'为材料,通过盆栽试验研究了不同浓度锌处理对油菜生长、产量和养分吸收的影响及其在植株地上部器官中的富集特征.结果表明:低浓度锌处理( 100 mg·kg-1),一定程度刺激了油菜的生长,植株的花期生物量、光合速率、产量和主要矿质元素含量等指标均与对照差异不显著.随着土壤中锌浓度的增大,植株的花期生物量、光合速率、产量、主要矿质元素含量、株高和主花序长等指标均显著下降(P＜0.05),而一次分枝数变化不明显.油菜地上部不同器官对锌的富集特征差异显著,总体上呈现出茎秆中的含量大于籽粒中的趋势. |

| Abstract: | A pot experiment was conducted to study the effects of different zinc treatments on growth,yield,and nutrient uptake and enrichment characteristics of zinc in above-ground organs of rapeseed(B.napus cv.'Qinyou 9').Comparing with the control,low zinc level in soil stimulated the rape growth to some extent,but had less effect on the plant biomass,photosynthetic rate yield and main mineral element contents.With the further increase of zinc level in soil,the plant biomass,photosynthetic rate,yield,main mineral ... |
