在世界上的主要葡萄品种中,类似于巨峰的四倍体品种是较少的,其与二倍体葡萄品种的树势管理方法是不一样的。四倍体的大粒系葡萄品种容易落花,其幼树的树势旺盛,顶芽优势显著,若修剪过重,则会徒长。因此,对其进行树势管理时,幼树应采取弱剪方法,从事自然形的长梢修剪。否则,短梢修剪定会使修剪过重,造成新梢的生长势较强,导致其营养生长与生殖生长失去平 Among the main grape varieties in the world, tetraploid varieties similar to Jufeng are relatively rare, which is different from the method of tree management of diploid grape varieties. Tetraploid large grain grapes easily fall flowers, saplings of its sapling strong, the top bud significant advantages, if the pruning, will be leggy. Therefore, tree management should be carried out on young saplings to take the method of weak shears to do the natural long shoot pruning. Otherwise, the short tip pruning will make the pruning too heavy, resulting in strong shoot growth potential, leading to loss of vegetative and reproductive growth
