摘  要：
试验设置固定隔沟灌和交替隔沟灌两种灌溉方式,每种灌溉方式设置2个灌水水平和2个施氮水平,共8个处理,展开不同水氮组合对温室番茄光合特性影响的研究。结果表明:追肥前番茄叶片光合速率日变化呈"双峰"曲线,追肥后出现"双峰"和"单峰"两种曲线。追肥前后番茄的蒸腾速率日变化均呈"单峰"曲线。追肥前,交替隔沟灌均能提高番茄叶片的光合速率和蒸腾速率,高水处理表现得更显著。追肥后,交替隔沟灌比固定隔沟灌能显著提高番茄叶片的蒸腾速率,交替隔沟灌高水或固定隔沟灌低肥处理均可明显提高番茄的蒸腾速率。

摘  要：
The coupling effect of water and nitrogen on the photosynthetic rate and transpiation rate of greenhouse tomato was studied by setting up two irrigation methods with 8 treatments,which were fixed furrow irrigation and alternative furrow irrigation,each irrigation method with 2 water levels and 2 nitrogen levels. The results indicate that: the photosynthetic rate of tomato shows the "double peak"curve before adding fertilizer,and the two curves of "double peak"and "single peak"after adding fertilizer; the transpiration rate of tomato shows the"single peak"curve before and after adding fertilizer; the photosynthetic rate and transpiration rate of tomato leaves can be improved under the alternative furrow irrigation before adding fertilizer,and it performances more significantly under the high water treatment; after fertilization,the transpiration rate of tomato leaves can be improved under the alternative furrow irrigation or under alternative furrow irrigation with higher water or fixed furrow irrigation with lower fertilizer.
