Abstract：In spring of 2007 ,three-year-old Fujiminori (Vitis viniferaxV, labrusca) vines were transplanted into trough (60 cm in width and 30 cm in depth) with spacing of 60 cm. The bed was divided into two equivalent parts, full of a mixture of garden soil ,sand and mature mushroom slag. The vine roots were distributed into the two parts. Experiment was conducted with a complete randomized design with 4 drip-irrigation treatments, including PRDs (partial root-zone drying) and DI (dou-ble irrigation). Shoots were pinched before the beginning of flowering,lateral shoots were pinched with one piece of leaf re-tained. 2,4,6 shoots were set respectively for the three PRDs,and that was 54 L,27 L and 18 L of wetting volume for each shoot. 4 shoots were set for the DI. The vines were used to evaluate the vegetative growth ,fruit development and soil water po-tential in response to the wetting volume under partial root-zone drying and conventional double irrigation. Results showed that,the treatment with 27 L wetting volume for each shoot with 0.6～0.7 m~2 leaf area has no difference with the conventional double irrigation treatment which had the same wetting volume on water potential of wet zone, fruit yield and quality, but with increased the water use efficiency. The results suggested that 50 L wetting volume per m~2 leaf area could meet the requirement of the growth and berry development for grapevine under partial root-zone drying.
