摘　　要：[目的]研究干旱区赤霞珠葡萄(Vitis vinifera L.cv.‘Cabernet Sauvignon’)着色期含糖量的变化规律,并拟合其数学模型。[方法]对干旱区栽培的赤霞珠葡萄,在着色期进行定期多点测定含糖量。[结果]赤霞珠葡萄可溶性固形物含量的增加有2个明显不同的阶段,其中以第1阶段增长最快,可溶性固形物增量占采收时总含糖量的27.1%,日均增糖量为0.32%,为葡萄果实快速增糖期。而且U型架比篱架含糖量增加0.20～1.50个百分点。数学模型验证表明,赤霞珠葡萄含糖量增加的规律符合直线回归方程。[结论]该研究可为确定葡萄适宜的采收期,为酿酒葡萄的优质高效丰产提供理论依据。[Objective] The aim was to study the sugar content change law of Cabernet Sauvignon grape during coloring stage in Arid Areas,and simulating its mathematical model.[Method] The sugar content of Cabernet Sauvignon grape in Arid Areas during coloring stage were determined.[Result] The results show that Cabernet Sauvignon grape＇s soluble solids content has two distinct increase stages,of which phase 1 is the fastest growing,soluble solids content represents 27.1% of the total sugar content,and the sugar average daily increase amount is 0.32%.The sugar content when using U-shaped frame increases 0.2-0.5 percentage point than trellis.Mathematical model validation shows that the increase of Cabernet Sauvignon shape sugar content fits the basic laws of linear regression equation.[Conclusion] The study provides a theoretical basis for confirming the suitable harvesting time and high efficiency and high yield production of vinifera.
