摘  要：
为探究钾肥对‘玫瑰香’葡萄品质的影响，以 6 年生‘玫瑰香’葡萄为试材，研究了 3 种钾肥施用量（30、40 和 50 kg/667m~2）对果实品质（硬度、果形指数、含水量、可溶性固形物、可溶性糖、可滴定酸、可溶性蛋白以及 VC 含量）的影响。结果显示：钾肥施用量为 30 kg/667m~2时，果实的硬度（1.03 kg/cm~2）、可溶性糖含量（5.37 mg/g）、果形指数（1.2）最高，显著高于其他处理，其可滴定酸含量（0.22%）、含水量（74.35%）显著低于其他处理。隶属函数综合分析得出，施用量为 30 kg/667m~2的钾肥处理，果实的综合品质最好，平均隶属函数值为 1.16，其次是 40 kg/667m~2的处理，平均隶属函数值为 0.80。因此，补施 30 kg/667m~(2 )钾肥可显著提高‘玫瑰香’果实的品质。

摘  要：
In order to explore the effects of potassium fertilizer on the quality of ‘Muscat Hamburg’ grapes, the effects of three potassium fertilization(30, 40 and 50 kg/667m~2)on fruit quality(hardness, fruit shape index, water content, soluble solids,soluble sugar, titratable acid, soluble protein, and VC content)were studied using 6-year-old ‘Muscat Hamburg’ grapes as the test material. The results showed that when the potassium fertilization was 30 kg/667m~2, the hardness(1.03 kg/cm~2), soluble sugar content(5.37 mg/g)and fruit shape index(1.2)of the fruit was the highest, which was significantly higher than other treatments and its titratable acid content(0.22%)and the water content(74.35%)were significantly lower than other treatments. The comprehensive analysis of the membership function showed that the potassium fertilization treatment 30 kg/667m~2 had the best comprehensive quality of the fruit, with an average membership function value of 1.16, followed by the treatment of 40kg/667m~2, with an average membership function value of 0.80. Therefore, supplementary application of 30 kg/667m~2 potassium fertilization can significantly improve the quality of ‘Muscat Hamburg’ grapes.
