葡萄嫁接苗与自根苗相比,根系抗寒力可提高5～8℃,既能减少冬季防寒用工用费,又能促进苗木生长旺盛、提早结果。所以,在我省(尤其中北部地区)发展嫁接葡萄十分必要。葡萄嫁接苗培育方法主要有两种。一、硬枝嫁接嫁接前,先将贮存的山葡萄或贝达砧木枝条剪成20～25厘米长的枝段。枝段顶芽以上要剪留4厘米,下端芽下面留1厘米左右剪成斜茬。然后将砧木下端用锯纵向划伤几道,
Grafted grapes and grafted rootstock compared to the root cold resistance can be increased by 5 ~ 8 ℃, both to reduce winter cold use fees, but also to promote the vigorous growth of seedlings, early results. Therefore, grafting grapes in our province (especially in the central and northern regions) is very necessary. There are two main methods of grafting grape grafting. First, the hard grafting Grafting before grafting, first stored in the mountain grape or Beida rootstock branches cut into 20 to 25 cm long branches. Branches above the bud to cut the top 4 cm, below the bottom of the bud to leave about 1 cm cut into stubble. Then the bottom of the rootstock saw a few longitudinal cuts with saws,
