摘　　要：为研究追施有机滴灌肥在酿酒葡萄和葡萄酒品质上的应用效果,以5年生酿酒葡萄“赤霞珠”为试验材料,通过田间试验设置常规施肥(CK)、常规施肥+生物有机肥提取液(T1)、常规施肥+氨基酸肥(T2)、常规施肥+海藻肥(T3)、常规施肥+沼液肥(T4),分析不同有机滴灌肥处理下酿酒葡萄与葡萄酒品质状况。通过主成分和聚类分析,综合评价不同施肥处理下品质差异,采用最短距离法对各施肥处理进行系统聚类。结果表明,酿酒葡萄与葡萄酒的品质指标表现出显著或极显著的正相关关系;综合品质质量排序为T3>T4>T2>T1>CK;不同施肥处理下葡萄与葡萄酒品质质量可聚为3类,常规施肥处理单独聚为一类,品质质量为三等,常规施肥+生物有机肥提取液和常规处理+氨基酸两个处理聚为一类,品质质量为二等,常规施肥+海藻肥和常规施肥+沼液肥两个处理聚为一类,品质质量为一等,最好。综合评价,在常规处理基础上追施海藻肥对提高葡萄与葡萄酒品质的效果最为明显。In order to study the effect of application of organic fertilizer drip irrigation on the quality of wine grapes and wine,field experiment was conducted using 5-year-old wine grape“Cabernet Sauvignon”as the material.Five treatments was set up,including the conventional fertilization(CK),conventional fertilization+bio-organic fertilizer extract(T1),conventional fertilization+amino acid fertilizer(T2),conventional fertilization+seaweed fertilizer(T3),conventional fertilization+biogas slurry fertilizer(T4),and the quality of wine grapes and wines under different organic drip irrigation treatments was analyzed.Through principal component and clustering analysis,the quality difference under different fertilization treatments was comprehensively evaluated,and the shortest distance method was used to systematically cluster each fertilization treatment.There was a significant or extremely significant positive correlation between the quality indexes of wine grapes and wines.The overall quality ranking was T3>T4>T2>T1>CK.The quality of grapes and wines under different fertilization treatments could be clustered into three categories.Conventional fertilization treatment was clustered into the first clustering,and the quality was third-class.The conventional fertilization+bio-organic fertilizer extract,and conventional treatment+amino acid were clustered into the second clustering,the quality was secondclass.Conventional fertilization+seaweed fertilizer and conventional fertilization+biogas slurry fertilizer were clustered into the third clustering,and the quality was the best.By comprehensive evaluation,T3 was the most effective in improving the quality of grapes and wine.
