我们根据多年的实践经验,摸索出老葡萄树的更新措施,现介绍如下:1.如基部有徒长枝,于秋季10月中下旬葡萄下架时整型修剪,可将老主蔓从基部砍除或砍主侧蔓分枝处,以徒长枝代替主蔓,重新造型。2.如果基部无徒长枝,则宜先从春季开始,做培养枝的工作,到秋季下架时,再砍除老蔓。在同一果园内,换老蔓宜逐年分批进行,切不可操之过急,以免造成推光头,引起减产。
According to many years of practical experience, we found out the old vine regeneration measures are as follows: 1. If the base is only a long branch, in the fall of late October when the grapes off the shelves, the owner can be cut from the base of the vine In addition to or cut off the main side of the vine branches, to the main branch of the main vine, re-modeling. 2. If the base without unfractionated branches, it should be from the beginning of the spring, to do the work of cultivating branches, to fall off the shelf, and then cut off the old vine. In the same orchards, the old man should be gradually replaced year by year, must not be too hasty, so as not to cause push head, causing cut.
