摘　　要：以3～4a生野生毛葡萄两性花品种"野酿2号"为试材,研究比较了冬剪和夏剪技术对野生毛葡萄坐果率和产量、效益的影响。结果表明:双层"干"字整形法不适于该品种,顶端萌芽和生长优势极强。生产上对2～3a幼龄树冬剪可采取7芽以上中长修剪法,夏剪结果枝留穗数与末穗前留叶数比例以1∶(1.5～2.5)为佳,可获得50%的收果率。4a以上成龄树冬剪宜采用3～6个芽中短剪法,夏剪穗叶比则以1∶3为好,可获得30%的收果率。花前副梢留1叶摘心,副梢全留或只留末穗前全部副梢,收果率在30%以上。Taking 3~4 years old bisexual cultivars（＇Yeniang No.2＇）of wild downy grape as materials,the pruning in winter and summer were conducted.The results showed that the trimming method of double layer with GAN shape was not suitable for this cultivar,owning to apical shoots with dominating sprout and growth.As for the 2~3 years old young trees,the method of pruning middle to long stems with more than seven buds was favorable in winter;The ratio of the remaining spikes of fruiting stems to the leaves of the plant was preferable as 1 to 1.5~2.5,with 50% of fruition rate in production.As for the over 4 years old trees,the method of pruning short to middle stems with 3~6 buds was favorable in winter;the ratio of fruit to leaves remained was better as 1 to 3 in summer,with 30% of fruition rate.The fruition rate could reach up to 30%,if the auxiliary buds disbudded with one leaf remained before flowering,and had all the auxiliary buds remained
