摘　　要：研究避雨栽培对酿酒葡萄果实采收期、果实品质和葡萄酒质量的影响,为酿酒葡萄避雨栽培技术的实施提供理论依据。以蛇龙珠(Vitis viniferaL cv.Cabernet Gernischt)为材料,采用简单避雨方式和露地栽培(对照),在果实转色期后监测果实糖酸变化,并测定成熟果实还原糖、总酸、花色素、总酚和单宁等指标;采用小容器酿造工艺酿制蛇龙珠干红葡萄酒,测定葡萄酒的颜色、花色素、总酚和单宁等指标。结果表明:(1)避雨栽培推迟了蛇龙珠果实的成熟期;(2)避雨栽培对蛇龙珠果实花色素、葡萄果皮中单宁含量影响极显著,对其他指标没有显著影响;(3)避雨栽培对蛇龙珠干红葡萄酒花色素含量及颜色影响极显著,对总酚和单宁含量无显著影响。The effects of rain protection cultivation on the harvest time,berry and wine quality of Vitis vinifera L cv.Cabernet Gernischt were studied,which could provide a theoretical basis for the practice of rain protection cultivation in vineyard.The rain protection cultivation of Cabernet Gernischt grapevine was evaluated with open field cultivation as control.The contents of sugar and total acids in berry during ripening were monitored.The contents of reducing sugars,total acids,anthocyanins,total phenolics and tannins in ripened berry were measured.The Cabernet Gernischt dry red wine was brewed by traditional technology in a small container.The chromatic characteristics and the contents of anthocyanins,total phenolics and tannins of the wine were determined.The results showed that：（1） the mature period of Cabernet Gernischt was postponed by rain protection cultivation;（2） only the contents of anthocyanins and tannins in skin were significantly affected by rain shelter cultivation;（3） only anthocyanin contents and chromatic characteristics of the wine were significantly affected by rain protection cultivation.
