摘  要：
以番茄为试验材料,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产量、平均单果重和水分利用效率影响的研究,结果表明:增加灌水量可提高番茄的产量和交替隔沟灌溉下番茄的平均单果重。降低灌水量或施氮量时,水氮必须满足一定比例才可增加番茄平均单果重和提高交替隔沟灌下番茄的水分利用效率。水氮耦合、氮是影响番茄产量、平均单果重和水分利用效率的主要因素。水是影响番茄产量、平均单果重和固定隔沟灌番茄水分利用效率的主要因素。灌溉方式是影响番茄产量和水分利用效率的主要因素。

摘  要：
The effect of different combination of water and nitrogen on the yield,average single fruit weight and water use efficiency of greenhouse tomato is studied through selecting tomato as experiment material and setting two irrigation modes,namely fixed furrow irrigation and alternative furrow irrigation,in which each has two water levels and two nitrogen levels and the total is eight treatments.The results show that increasing irrigation water can increase the yield and the average single fruit weight of tomato under alternative furrow irrigation;when reducing irrigation water or nitrogen application rate,average single fruit weight and water use efficiency under alternative furrow irrigation can be improved only with certain proportion of water and nitrogen;Water and nitrogen coupling and nitrogen are the main factors affecting the yield,average single fruit weight and water use efficiency under alternative furrow irrigation;water was the main factor affecting the yield,average fruit weight and water use efficiency under fixed furrow irrigation;irrigation mode is the main factor influencing the yield and water use efficiency.
