求翻译：每年生长季节结束后，在冬天来临之前，要将葡萄藤的主干上的大部分的枝桠剪除，也就是将上一个生长季节里所生长的枝叶去除，只留下少数枝芽，以待明年生长季节的即时生长。冬季修剪枝芽的动作，是葡萄农夫控制第二年产量和葡萄品质的一个重要方法。是什么意思？

Each year after the end of the season, before the winter comes, to most of the vines on the backbone of the branches cut off, that is, with the growth of branches and leaves in the last growing season removed, leaving only a few branches and buds, instant growth until next year's growing season. Action of pruning branches and buds in winter, is the second annual grape farmer control, and an important method of grape quality.
