摘要: 在葡萄品种'赤霞珠'生产园行间播种多年生黑麦草、紫花苜蓿、白三叶草,在葡萄果实成熟过程中分析其含糖量和含酸量的变化趋势,并进行酿酒试验及葡萄酒理化指标分析和感官品评,以探讨行间生草对'赤霞珠'干红葡萄酒质量的影响。结果表明,与清耕相比,行间生草可使葡萄果实还原糖含量增加,含酸量降低;葡萄酒中pH值、花色素苷、单宁含量升高,酒体颜色加深,结构感增强。因此,行间生草使'赤霞珠'葡萄果实及葡萄酒品质提高。

Abstract: The effects of vineyard green cover with white clover (Trifolium repens),perennial ryegrass (Lolium perenne) and alfalfa (Medicago sativa) on wine quality of 'Cabernet Sauvignon' were studied. The variation of grape berry reducing sugar content and total acid content was determined during maturing. Wine components were determined by comparing to clean tillage. The sensory quality of the wines was evaluated after winemaking. The results showed that reducing sugar content of berry increased, total acid content of grape berry decreased, while the pH, anthocyan, tannin of wine increased. Compared with those of clean tillage, significant difference in wine color and configuration occurred. It can be concluded that green cover improved the quality of grape berry and wine evidently.
