本文报告了在小麦籽粒灌浆期间用水喷雾提高叶片光合速率以及单位面积产量的结果。光合速率的提高与叶片气孔阻力降低有关。单位面积产量的增加是籽粒饱满程度提高的结果。本研究进一步证实了前文的结论,并且表明用少量水可以改善田间小气候和作物水分状况,减轻光合作用“午睡”现象,提高光合速率,进而增加作物产量。
This paper reports the results of using water spray to increase leaf photosynthetic rate and yield per unit area during wheat grain filling. The increase of photosynthetic rate is related to the reduction of leaf stomatal resistance. The increase in yield per unit area is the result of increased grain fullness. This study further confirms the previous conclusions and shows that using a small amount of water can improve the microclimate and crop moisture in the field, reduce “nap” phenomenon of photosynthesis, increase photosynthetic rate, and then increase crop yield.
