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/667m2)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/667m2时,果实的硬度(1.03 kg/cm2)、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/667m2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/667m2的处理,平均隶属函数值为0.80。因此,补施30 kg/667m2 钾肥可显著提高‘玫瑰香’果实的品质。

Abstract: 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/667m2)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/667m2, the hardness(1.03 kg/cm2), 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/667m2 had the best comprehensive quality of the fruit, with an average membership function value of 1.16, followed by the treatment of 40 kg/667m2, with an average membership function value of 0.80. Therefore, supplementary application of 30 kg/667m2 potassium fertilization can significantly improve the quality of ‘Muscat Hamburg’ grapes.
