桂南雷司令反季节栽培与酿酒特性的初步研究

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。本文利用反季节栽培技术，采用避雨栽培，人工诱发萌芽等措施，使雷司令葡萄在该地区成功种植。以反季节栽培的雷司令冬果为原料进行酿酒实验，并对果实及葡萄酒品质进行分析，利用GC-MS检测香气物质。结果表明反季节栽培的雷司令在桂南地区生长表现良好，葡萄酒中含有28种酯类，6种醇类，7种羧酸类，3种其他香气物质，表现出品种的特征香气。

Study on the Off-season Cultivation and Vinification Characteristics of Riesling Grape in the Southern Guangxi

The south of Guangxi belongs to the subtropical monsoon climate, where has abundant sunshine and heat resources, rare rain in winter. Riesling grape can be planted successfully by using off-season cultivation technique, rainproof cultivation and artificial inducing sprout in southern Guangxi. The second-crop Riesling grape was used as raw materials for wine-making experiments. The qualities of grape and wine were analyzed and studied, and the major flavoring compositions of the produced wine were analyzed by GC-MS. The results showed that Riesling grew well in the south of Guangxi with off-season cultivation technique, the wine contains 28 esters, 6 alcohols, 7 acids and 3 others. The characteristic aromas were exposed in the wine.
