| 摘 要： | 在烤烟生长季节设逐沟灌(对照)、交替隔沟灌、微喷灌、摇臂式喷灌、滴灌五种灌水方式,利用LI-6400便携式光合作用仪研究了不同灌水方式对烤烟光合作用的影响。结果表明:与对照相比,各处理不同程度地提高烤烟大田现蕾期以前的光合能力,降低蒸腾速率,提高叶片水分利用效率。特别是,摇臂式喷灌使烤烟的光合速率(Pn)提高了7.05%~24.97%、蒸腾速率(Tr)减少了5.10%~38.74%、WUE提高了16.48%~83.01%,滴灌使烤烟的Pn提高了6.23%~22.71%、Tr减少了7.65%~39.92%、WUE提高了34.55%~78.15%,而且使烟田供肥特性和烟株光合生理与烤烟的生长发育规律相吻合,利于烤烟及时落黄,是烟田最优的灌溉方式,而交替隔沟灌和微喷灌可以用作烟田前期灌溉。
