研究结果表明，大粒鲜食葡萄结果母枝径粗在０．８ｃｍ以上才有结实能力，在０．８～１．５ｃｍ的粗度范围内与结实能力呈直线正相关。花芽形成与芽所处节位不相关。结果母枝冬季的剪留长度对萌芽率的影响不显著，而对果穗数量有显著影响，大小因品种而异。并在此基础上，提出了不同品种的相应冬剪方法 The results showed that the results showed that the fruiting diameter of grapes was greater than 0.8 cm in the grapes, and there was a linear positive correlation between the fruiting ability and the grafting ability in the range of 0.8-1.5 cm. Flower bud formation is not related to the node where the buds are located. Results The length of cuttings in winter of mother plant had no significant effect on the germination rate, but had significant effect on the number of ears. The size varied according to the variety. On this basis, the corresponding winter cut methods of different varieties are put forward
