| 摘 要： | 为探究硅、镁、锌互作最优配比以提高水稻产量,以水稻品种龙粳29为试材,利用二次回归正交旋转设计方案研究硅镁锌不同配比用量对水稻光合作用及产量的影响。结果表明:净光合速率与产量呈负相关,气孔导度、胞间二氧化碳浓度和蒸腾速率与产量呈正相关,气孔导度对产量的影响最大,施用中间量的硅镁锌肥能使气孔导度达到最大值。

| Abstract: | The effect of different amount of silicon,magnesium and zinc on rice photosynthesis and yield were studied,using second orthogonal returnation rotation design program.The result showed that the net photosynthetic rate was negative correlative with yield.The stomatal conductance,intercellular CO_2 concentration and transpiration rate was positive correlative with yield.But,stomatal conductance impacted yield greatly most.The stomatal conductance will reach max while the three kind of fertilizers staying middle levels. |
