| 摘 要： | 以济麦22为供试材料,在相同密度条件下,通过不同的种植方式和三种施氮量组合,探讨种植方式与施氮量对冬小麦光合生理特性及光能利用率的影响。结果表明：冬小麦＂20 cm＋40 cm＂沟播（沟播）能够显著提高小麦旗叶光合速率（Pn）、荧光参数与叶绿素含量指数（CCI）,从而维持较好的叶片光合生理功能。沟播光能利用率平均值显著高于平作大小行与等行距。施氮量增加显著提高冬小麦Pn、荧光参数与CCI等生理指标,光能利用率也随之提高。施氮量对冬小麦光合生理指标及光能利用率的影响超过种植方式。

| Abstract: | Jimai 22 was planted with different patterns and 3 nitrogen application rates at different densities,then their effects on the light use efficiency were discussed.The results indicated that the(20+40)-cm furrow planting could improve the photosynthetic rate(Pn),fluorescence parameter and chlorophyll content index(CCI) in the flag leaves of winter wheat.So the photosynthetic physiological function was kept better.The light use efficiency with furrow planting was obviously higher than that with flat planting ... |
