摘　　要：以3年生藤稔葡萄为材料,探讨了灌水下限对部分根域干燥栽培葡萄生长发育的影响。结果表明,部分根域干燥条件下,转色期之后设施葡萄灌水下限应该控制在-30kPa左右,即土壤饱和持水量的70%左右,此时叶面积生长量没有显著减少,果实产量、品质与双侧灌溉处理没有显著差异,但灌溉水利用效率显著提高。The influence of irrigation low limit on growth and development of three years old Fujiminori plant was studied under partial root-zone drying cultivation. The results showed that the water potential should be controlled at -30kPa, which was 70% of saturated soil water content after veraison. And leaf area growth amount did not significantly reduce, the fruit yield and quality had no difference with the conventional double irrigation. But the irrigation water use efficiency was increased significantly.
