| 摘 要： | 以6个不同品质基因型大豆品种为试材,探讨了苗期追施尿素对叶片光合生理和植株干物质积累的影响。结果表明:随着生育进程,各品种的叶面积指数、叶色值和光合速率呈单峰曲线变化,干物质积累呈"S"型曲线。苗期追施尿素会对开花期至鼓粒初期大豆的叶面积指数、光合速率和叶色值产生显著影响,单株干物质积累最大速率和平均速率在施肥处理间均存在极显著差异。追施氮肥会使单株干物质最大积累速率出现时间提前,以高蛋白品种提前天数最多。

| Abstract: | Six soybean cultivars of different quality genotypes were used to study the effects of N fertilizer on photosynthetic physiology and dry matter accumulation.The experiment was carried out by the split plot design in field.The results showed that as the growth and development of plant,the LAI,leaf greenness and leaf photosynthetic rate showed a single-peak curve,while the dry matter accumulation showed a typical S curve.There were significant effects on LAI,leaf photosynthetic rate and leaf greenness from th... |
