在张掖市灌溉试验站开展了设施延后栽培葡萄灌溉试验，研究了不同生育期水分胁迫对温室栽培葡萄光合指标的影响。结果表明，各个胁迫处理下光合速率均大于对照处理，而胞间CO2浓度相比对照均有明显下降，且以生育期的先后胁迫顺序从高到低排列。水分胁迫可以提高设施延后栽培葡萄的外观品质，以开花期胁迫处理下果粒重、纵横径最大。萌芽期胁迫处理使得果实产量增加，营养品质有所提高，并且叶片水分利用效率最高，可为设施延后栽培葡萄节水、调质、增效的灌溉制度提供依据。

The experiment was carried out at Zhangye Irrigation Experiment Station in Gansu Province to investigate the effects of water stress in different stages on the change of photosynthetic properties of greenhouse grape under delayed cultivation .The results showed that the net photosynthetic rate under all treatments of water stress was higher than that under the control .However the intercellular CO2 concentration under all treatments of water stress was obviously lower than that under the control ,and it was ranked from high to low according to the successive order of water stress .Water stress could improve the appearance quality of delayed grape .The single fruit weight ,longitudinal diameter and trans-verse diameter were the largest under moderate water stress in flowering stage .Under the treatment of moderate water stress in sprout stage ,both the yield and the nutritional quality of grape could be improved ,and the water use efficiency of leaves was the highest .These results could provide basis for irrigation system of greenhouse grape under delayed culti-vation so as to save water ,improve quality and increase efficiency .
