【摘要】 采用裂区设计,研究了品种和肥料对冬小麦叶片主要生理参数和产量及水分利用效率的影响。结果表明,不同品种之间的净光合速率、蒸腾速率、籽粒产量有显著差异,但气孔导度、水分利用效率差异不明显。增施肥料提高了叶片光合速率,并且它与施肥水平和生育阶段有关。更多还原

【Abstract】 The effects of fertilizing on physiological index of leaves, yield and WUE(water using efficiency) of two winter wheat cultivars were determined. The results showed that between two cultivars, the net photosynthetic rate, transpiration rate and grain yield were significantly different while stomatal conductance and WUE were not obviously different between two cultivars. Fertilization which was related to fertilization amount and different growth stages improved photosynthetic rate of leaves.更多还原
