中文摘要:

依据冬小麦不同水分处理的灌溉试验,分析了抽穗期5种土壤水分条件下叶片气孔导度、冠气温差及光合速率等生理指标的日变化规律,并对各生理指标间进行了相关性分析。结果表明:土壤水分对冬小麦抽穗期气孔导度、冠气温差及光合速率有着显著的影响,且各指标日变化趋势基本一致；气孔导度与冠气温差、光合速率均呈正向相关,两者均随气孔导度的增加呈上升趋势,但不同土壤水分条件下上升幅度不同。

英文摘要:

Based on the irrigation experiment of winter wheat in different water treatments, the paper analyzed the daily variation rule of stomatal conductance,canopy-air temperature difference, photosynthetic rate etc physiological indicators of winter wheat in heading stage under 5conditions of soil moisture, and carried out the correlation analysis between physiological indicators. The result indicated that the change of soil moisture has significant effect to physiological indexes such as tomatal conductance,canopy-air temperature difference and photosynthetic rate of winter wheat in heading stage, and the daily variation trend of each index is almost synchronous. Stomatal conductance appears active correlation with canopy-air temperature difference and photosynthesis rate. The canopy-air temperature difference and photosynthesis speed rise with the increase of stomatal conductance of winter wheat at heading stage. But the amplitude is different under different moisture conditions.
