摘　　要：以6年生"赤霞珠"葡萄为试材,比较了香格里拉高海拔地区葡萄在留结果枝为12枝/株与18枝/株的条件下,不同时间摘叶处理对果实品质的影响。结果表明:于葡萄转色前期和中期摘除"赤霞珠"葡萄果穗及果穗以下的全部叶片可显著增加果实含糖量,降低酸度,摘叶处理对果实糖酸比、pH值、总酚、丹宁等多项果实品质指标均有不同程度的提高。不同时间摘叶处理使葡萄枝条的总糖与淀粉含量均有所降低,而在转色中期(8月16日)进行摘叶处理对果树枝条的碳素营养没有造成显著影响。In order to study the effect of different time to remove leaves from fruit brances on grape quality and 1-year-old shoots stored carbon nutrition of 12 and 18 branchs in Shangri-La,6 years of ＇Cabernet Sauvignon＇ grape were used as the materials. The results showed leaf removing of August 1st and August 16th could make total sugar, total phenol, tannin,pH value and sugar acid ratio increas in different degree, and titratable acid content decreas. 1-year-old shoots stored total sugar and starch content of grape were decreased after leaf removing,but leaf removing of August 16th had no significant effect on carbon nutrition of the branches.
