摘要：

以鲜食葡萄品种"金手指"为试材,研究了不同冬季修剪长度(单芽、双芽、三芽和四芽修剪)对"金手指"葡萄结果母枝萌芽率、结果枝率、结果系数及花序着生情况的影响。结果表明:"金手指"葡萄结果母枝的萌芽率、结果枝率随修剪长度的增加呈现明显的下降趋势,中梢修剪(3~4芽修剪)与短梢修剪(1~2芽修剪)相比较,低节位冬芽的萌芽率较低,易导致树冠结果部位上移,从而缩短树体寿命;结果母枝留芽量对新梢结果系数的影响不大,花序分布在结果枝的第2~5节位,但主要着生在结果枝的第3~4节位。表明"金手指"葡萄在冬季修剪时适宜采用短梢修剪(1~2芽修剪)方式,适当增加短枝数量即可保证翌年产量。

摘要：

Taking grape variety ‘Gold Finger'as test material,the effects of different canes length(single bud,double buds,three buds,four buds)pruned on fruit cane germination rate,fruit branch rate,fruiting coefficient and position of flower bud differentiation for grape were evaluated.The results showed that,under different pruning ways,with the increasing of length of trim,it had a significant downward trend for fruit cane germination rate and fruit branch rate.Compared with single and double buds pruning,three and four buds pruning could get a low fruit cane germination rate,which would easily move up the setting fruit position and shorten the life of tree.There was no significant influence on the fruiting coefficient in different pruning way.Moreover,inflorescence was distributed in the second to fifth node of the fruit cane,but mainly in the third to the fourth node.It could be concluded that short shoot pruning methods(1-2buds pruning)could be applied in winter pruning of‘Gold Finger',and some canes number could be added reasonably to achieve a good yield next year.
