| 摘 要： | 目的]研究超级稻Ⅱ优602植株对N素水平和配置方式的动态反应。方法]试验以II优602为材料,分析不同施N量及配置方式下功能叶、叶鞘、茎秆全N含量的动态变化。结果]不同N素水平下功能叶的最高全N含量出现的时期不同,其中A3水平下以复水期最高。齐穗期、成熟期植株各部位的全N含量均表现为施肥处理>CK,功能叶>叶鞘>茎秆,而不同处理下,植株不同部位的全N含量表现出明显的差异。Ⅱ优602在成都平原种植,适宜的施N水平和配置方式为:N素165kg/hm2,底肥:追肥=6:4。结论]该研究为超级杂交稻的高产栽培提供N素调控的理论依据。

| Abstract: | Objective] The paper was to study the dynamic responses of super rice IIyou602 plants to different nitrogen levels and configuration modes.Method] With super rice IIyou602 as test material,the dynamic changes of total N content in functional leaves,leaf sheaths and stems under different application amount of nitrogen and configuration modes were analyzed.Result] The highest total N content of functional leaves under different N levels appeared in the different periods,which was the highest during rehydration period in A3 level.The total N content in various plant positions during full heading stage and maturity stage showed fertilization treatments > CK,functional leaves > leaf sheaths > stems.The total N content in different plant positions showed obvious difference in different treatments.When the super rice IIyou602 was planted in Chengdu plain,the proper application level of N and configuration mode was as follows:165 kg/hm2,fertilizer:topdressing = 6:4.Conclusion] The study provided theoretical basis for nitrogen regulation of high yield cultivation of super hybrid rice. |
