| 摘 要： | 对大豆不同生育期地上部植株干物质动态和氮素积累与转运动态变化进行试验研究。结果表明,大豆各器官(除荚果外)干物质积累均在结荚至鼓粒期间达到高峰;不同器官氮素积累间存在差异,叶片呈单峰曲线,峰值出现在结荚期,叶柄、茎呈逐渐下降趋势,但变化幅度不大,结荚后荚果中氮素积累迅速增加;不同叶位叶片氮素含量先增加而后下降,不同叶位叶柄呈高-低-高的变化趋势。

| Abstract: | The dynamic of dry matter in upside-plant and the dynamic change of nitrogen accumulation and translocation on different development stage of soybean were studied.The results show that:accumulation of dry matter in each organ(except pod)were up to peak between pod-setting and pod-filling stage;but the difference was existed in nitrogen accumulation of different organ:nitrogen accumulation in leaf was a curve with one peak and the peak was in pod-setting stage;nitrogen accumulation in petiole and stem was in drop tendency,the am - plitude of variation was little;nitrogen accumulation was increase fast in pod after pod-setting stage,nitrogen content in leaf on different position was increase first and then decrease,nitrogen content in petiole on different position was high-low-high tendency. |
