桂南亚热带酿酒葡萄反季节栽培与酿酒特性初步研究

广西南部属于亚热带季风气候区，冬季光热资源丰富，降水稀少。利用反季节栽培技术，采用避雨栽培，人工诱发萌芽等措施，使赤霞珠和梅露辄葡萄在该地区成功种植。经检测赤霞珠和梅露辄的冬果总糖含量均达到130 g/L，总酸分别为7.58 g/L和7.42 g/L，利用GC-MS分析了两种单品种酒的挥发性成分，两种酒中检测并鉴定出的化合物达40种以上，赤霞珠干红葡萄酒中酯类占56.82%，醇类20.45%，酸类15.9%，其他6.8%。梅露辄干红葡萄酒中酯类占55.0%，醇类17.5%，酸20.0%，其他7.5%。研究结果表明反季节栽培的赤霞珠和梅露辄在桂南亚热带地区生长表现良好，葡萄酒表现出品种的特征香气。
