In order to explore different single plant loading on growth and fruit quality of wine grapes, using Cabernet Sauvignon wine grape as experiment materials, different single plant loading experiments were set in sandy soil and irrigation-silting soil of the eastern foot of Helan Mountain. Single fruit mass, total soluble sugar content, titratable acid content, leaves nutrient elements and mass of 100 fresh or dry leaves were determined under different single plant loading levels. The results showed that ratio of fresh mass to dry mass of 100 leaves in Cabernet Sauvignon was decreased ifrstly, and then increased in both the sandy soil and the irrigation-silting soil, with single plant loading increased. Contents of N, P and K in leaves and leaf stalks was decreased in the two kinds of soils, as single plant loading increased. But variation extent of K content in leaf stalk was larger in the sandy soil, and K content in leaf stalk in the single plant loading ifve bunches treatment was 87.31% higher than that in the single plant loading 25 bunches treatment. Under the condition of single plant loading 15 bunches, soluble sugar content in six-year-old Cabernet Sauvignon grapes reached 23.33%, single fruit mass was the minimum (1.36 g), and single bunch mass was the maximum (228.3 g) in the sandy soil. In the irrigation-silting soil, single fruit mass was minimum (1.35 g), total soluble sugar content was middle (17.94%), and ratio of sugar to acid was 24.24 under the condition of single plant loading 10 bunches treatment. Reasonable loading level signiifcantly inlfuenced fruit quality of wine grape, single plant 15 bunches was the reasonable loading level of six-year-old Cabernet Sauvignon grapes in the sandy soil, and single plant 10 bunches was the reasonable loading level in the irrigation-silting soil.%为了探索不同的单株负载量对酿酒葡萄生长及果实品质的影响，以赤霞珠酿酒葡萄为试材，设置了宁夏贺兰山东麓地区砾质沙土和灌淤土上赤霞珠不同单株负载量试验，测定了不同负载量水平下葡萄果实的单果质量、可溶性总糖含量、可滴定酸含量以及叶片的营养元素和百叶鲜干质量。结果表明：砾质沙土和灌淤土上赤霞珠叶片的百叶鲜干比均是先减小后增大；2种土壤上赤霞珠葡萄叶片和叶柄中氮、磷、钾含量均是随着单株负载量的增加而减少，砾质沙土叶柄钾含量的变异幅度较大，单株负载5串的处理比单株负载25串的处理叶柄钾含量高出87.31%；砾质沙土上6年生赤霞珠单株负载15串时可溶性总糖含量达到了23.33%，单果质量最小（1.36 g），单穗质量最大（228.3 g）；灌淤土上6年生赤霞珠则是单株负载10串时单果质量最小（1.35 g），可溶性总糖含量适中（17.94%），糖酸比24.24。合理的负载水平对酿酒葡萄果实品质影响较为显著，砾质沙土6年生赤霞珠合理的负载量为单株15串，灌淤土6年生赤霞珠合理的负载量为单株10串。
