摘　　要：【目的】探讨不同施肥处理对酿酒葡萄果实基本性状和酚类物质含量的影响,为酿酒葡萄果园科学合理施肥提供依据。【方法】以赤霞珠为研究对象,在蓬莱产区的君顶酒庄有限公司葡萄园内连续4a(年)实施5416试验。测定成熟期果实单穗质量、百粒质量、可溶性固形物含量、皮果比、籽果比、籽粒数及果皮和种子酚类物质含量等品质指标,并利用主成分分析法对其进行综合评价。利用SAS软件计算各品质指标达到最佳时的元素影响力排序和施肥配比。【结果】不同施肥处理对赤霞珠单穗质量和酚类物质含量有显著影响,对其他品质指标影响不显著。当施肥总量降低6.8%~11.2%时,其单穗质量及皮总酚、皮总黄酮、皮单宁含量等指标分别增加16.8%~33.8%、17.4%~26.4%、29.3%~33.1%、18.1%~35.5%。在相同施肥总量条件下,不同施肥配比对果实品质影响不同,与T9相比,T10处理更适合用于提升赤霞珠果实酚类物质含量。Mg元素对皮果比和果皮中总酚、花色苷、总黄酮、单宁含量影响力最大;K元素对籽果比和种子中总酚、总黄酮、黄烷醇、单宁含量影响力最大。通过主成分分析共提取5个主成分,其特征值分别为4.573、3.221、1.960、1.727、1.212,累积贡献率为84.612%。T9,T8,T2,T6处理分别对皮果比、总酚、花色苷、总黄酮、单宁含量,籽总酚、总黄酮、黄烷醇、单宁含量,可溶性固形物含量、百粒质量、皮黄烷醇含量,单穗质量的提高作用较强。除T6处理外,施肥处理的综合评价均高于不施肥处理(T1),T9处理的综合评分最高。【结论】N 124.5 kg∙hm^(-2)、P_(2)O_(5)0.0 kg∙hm^(-2)、K_(2)O 112.5 kg∙hm^(-2)、CaO 168.8 kg∙hm^(-2)、MgO 23.3 kg∙hm^(-2)是本试验条件下提高赤霞珠果实综合品质的最佳施用量。【Objective】The study examined the effects of different fertilization treatments on characters and phenolic content in wine grapes in order to provide reference for rational fertilization in wine grape orchards.【Methods】With Cabernet Sauvignon as the experimental materials,a fertilization experiment was carried out in the vineyard of Junding Winery Co,Ltd.in Penglai production area for 4 consecutive years.The fruit quality indicators such as single cluster weight,100-berry weight,soluble solids,skin recovery,seed recovery,number of seeds,and contents of phenolic substances in pericarp and seeds were measured at the mature stage,and the principal component analysis method was used to comprehensively evaluate the treatments.SAS analysis method was used to calculate the influence and ratio of elements.【Results】Fertilization treatments had significant effects on cluster weight and phenolic substances in Cabernet Sauvignon,but had no significant effects on other quality indicators.The total soluble solid content in different fertilization treatments was in the range of 20.7%(T12)-22.9%(T2);100-berry weight 120.2(T10)-133.5(T2)g;skin recovery 11.7%(T9)-15.8%(T1);seed recovery 5.8%(T4)-7.1%(T6);and per cluster number of berries 52.8(T4)-60.0(T6).The total phenol content in T7 was the highest,which was 10.650 mg∙g^(-1),17.876%-83.797%higher than the other treatments.The content of flavanol in different fertilization treatments ranged from 38.859(T6)to 62.647(T2)mg·g^(-1),and the content of flavanol in T2 was significantly(28.2%to 61.2%)higher than that in T4,T6,T8,T10 and T12.Except for T4 and T6,there was no significant difference in anthocyanin content among the other fertilization treatments,and the content in T9 treatment was the highest,which was 2.515 mg∙g^(-1).Tannin content in T9 was the highest(2.746 mg∙g^(-1)),which was significantly higher than that in the other treatments.Except for T5,T6 and T11,there was no significant difference in total phenol content among the other treatments.The total
