The results showed that both inadequate and excessive nitrogen application accelerated the decreasing process of leaf area index ( lai ) and chlorophyll content at later growth stage , which led to earlier leaf senescence 结果表明,氮肥用量不足或过量均加速了生长后期叶面积系数及穗叶叶绿素含量的下降进程,使叶片提早衰老,但二者作用机制不同。
The results showed that yield structure of the middling population treatment were the most excellent as a whole and its grain yield was the highest among the three treatments , while the dynamic of tiller and its formation into panicles , root - bleeding intensity / spikeltes , lai and its structure , dry matter accumulation and transportation were the most reasonable too 结果表明,中等群体处理的产量结构最优,在三处理中稻谷产量最高,其茎蘖消长与成穗、颖花伤流量、叶面积系数与结构以及干物质积累与转运总体上最为合理。
