摘　　要：以贺兰山东麓5年生红地球葡萄为供试材料,通过田间试验与室内分析方法,在相同滴灌条件下,研究了不同灌水次数对红地球葡萄生长发育及果实品质的影响。结果表明:相同滴灌条件下,灌水12次的葡萄梢长最长,副梢发生率最高,叶片鲜重和干重最大,鲜干比最大,干物质积累量最大;灌水12次的葡萄Vc、可溶性固形物和可溶性糖含量最高,灌水14次葡萄产量最大,还原性糖含量最高,总酸含量最低。Taking 5 years old of Red Globe grape as tested materials at the eastern foot of Helan Mountain,through field experiment and analysis,effects of different irrigation times on Red Globe grape growth and development and fruit quality were studied under the condition of the same irrigation. The results showed that：under the same condition of drip irrigation,irrigation with 12 times of grape shoot length,axillary shoot number were the highest,the fresh weight and dry weight of the leaves were the largest,The fresh and dry ratio was the largest,and the dry matter accumulation was the biggest. Irrigation with 12 times promoted the content of VC,soluble solid and soluble sugar,and irrigation with 14 times promoted yield and sugar reducing content and total acid content was the lowest.
