摘　　要：以“赤霞珠”为试材,在葡萄园行间覆盖砂石(Cover gravel,CG),利用砂石白天吸热快、夜晚降温快的自然属性,探究行间覆盖砂石对酿酒葡萄果实品质和香气物质的影响。实验以行间清耕为对照(Contrast check,CK),于果实转色前至成熟期监测植株微域环境,测定浆果品质及香气物质并分析差异。结果表明:与CK相比,CG增高了白天叶幕温度,降低了土层温度;CG加速了可溶性糖、花色苷和类黄酮的积累,成熟时分别较CK高12.2%、23.3%和12.7%;CG减缓了可滴定酸、单宁和总酚的降解,成熟时分别较CK高18.1%、22.3%和7.4%。CG和CK检测到的香气种类分别为45种和44种,共有香气成分为11种。CG增加了醛酮类和萜烯类化合物总的相对含量,分别较CK高10.7%和60.6%,脂类和醇类化合物有所减少,分别较CK减少25.6%和45.6%。因此,行间覆盖砂石有助于提高赤霞珠果实品质。To use the natural properties of gravel effectively,such as warming rapidly in the day and faster cooling at night.In this paper,we study the effect of inter-row gravel mulching on the quality and aroma of grape berry.The Cabernet Sauvignon was selected,and 2 treatments of line covering with gravel(CG)and tillage(CK)were configured.The microenvironment was monitored from the veraison to grape ripening stage.We measured the berry quality and aroma and analyzed the differences between the CG and CK.The results showed that compared with CK,the CG increased the leaf curtain temperature during the day and reduced soil temperature.Compared with CK,CG accelerated the accumulation of soluble sugar,anthocyanin and flavonoid,which increased soluble sugar by 12.2%,anthocyanin by 23.3%and flavonoid by 12.7%in mature grape berries.CG slowed the degradation of total acids,tannins and total phenol compared with CK,which increased total acids by 18.1%,tannins by 22.3%and total phenol by 7.4%in mature grape berries.A total of 45and 44 kinds of volatile compounds which included CG and CK,including 11 components.Compared with CK,CG increased the total relative content of ketones,aldehydes and terpenes,which was 10.7%and 60.6%higher than CK.CG reduced the relative content of ester and alcohol,which was 25.6%and 45.6%less than CK.These results indicating that CG can improved berry quality.
