Abstract: In order to find the best drip irrigation mode suitable for the wine vineyards in Hongsibao area, this paper took 6 a wine grape ‘Cabernet Sauvignon’ as the test material, and used drip irrigation as the irrigation method to design 5 different irrigation water gradients: 1 500 m³·hm^-2 (T1), 2 250 m³·hm^-2 (T2), 3 000 m³·hm^-2 (T3), 3 750 m³·hm^-2 (T4), and 4 500 m³·hm^-2 (T5). The effects of different drip irrigation on the growth, photosynthetic rate, water use efficiency, yield and quality of wine grape plants were analyzed. The results showed that: T4 treatment (3 750 m³·hm^-2) had the most significant effect on growth of new shoot length and plant height, the best nutrient absorption, and significantly increased the relative chlorophyll content (SPAD) and vegetation difference index (NDVI) of wine grape during the flowering and expansion stages, the dry matter accumulation of fresh leaves was the largest, the water use efficiency was the most significant (42.69%), and the yield per plant was the highest (2.24 kg). When the drip irrigation exceeded 3 750 m³·hm^-2, it caused a certain amount of yield reduction. In addition, tannin content decreased first and then increased with the increasing of drip irrigation, anthocyanin content increased first and then decreased with the increase of drip irrigation, and there was a significant positive correlation between total phenolic content in grape skins and drip irrigation. Under T4 treatment, the contents of soluble solid (19.87%), titrable acid (0.72%) and soluble sugar (19.44%) in wine grapes were all at relatively appropriate levels, with relatively high glycolic acid, high tannin (3051 mg·g^-1), the highest total phenol content (10.65 mg·g^-1), and the best grape quality, which was the optimal drip irrigation mode in this experiment.

摘要： 为了寻求适宜红寺堡地区酿酒葡萄园的最佳滴灌灌溉模式，以6年生酿酒葡萄‘赤霞珠（Cabernet Sauvignon）’为供试材料，灌水方式采用滴灌，设计5个不同灌水量梯度：1 500 m³·hm^-2（T1）、2 250 m³·hm^-2（T2）、3 000 m³·hm^-2（T3）、3 750 m³·hm^-2（T4）以及4 500 m³·hm^-2（T5），分析了不同滴灌量对酿酒葡萄植株生长、光合速率、水分利用效率、产量以及品质的影响。结果表明：T4（3 750 m³·hm^-2）处理对新梢长及株高生长促进作用最为显著，养分吸收状况最好，且能显著提高酿酒葡萄花期和膨大期叶绿素相对含量和植被差异指数值，鲜叶片干物质积累量最大，水分利用效率提高最为显著（42.69%），单株产量最高（2.24 kg）。当滴灌量超过3 750 m³·hm^-2时，则会引起一定量的减产。另外，单宁含量随滴灌量增加呈先减小后增加趋势，花色苷含量随滴灌量增加呈先增加后降低趋势，酿酒葡萄果皮总酚含量与滴灌量呈显著的正相关关系。T4处理下，酿酒葡萄可溶性固形物（19.87%）、可滴定酸含量（0.72%）及可溶性糖含量（19.44%）均处在相对适宜的水平，糖酸比较高，单宁含量高（30.51 mg·g^-1），总酚含量最大（10.65 mg·g^-1），葡萄品质最佳，是本研究中最佳滴灌灌溉模式。
