1. When the seedlings grow 3-4 leaves and spread them, only 1 strong seedlings will be left for vine cultivation, and all other sprouted new buds will be erased except tender tendrils. When the length of the main vine is 1.2m, the primary branch at the bottom of a vine of 20m will be erased, and the primary branch over 20cm will still be 1-2.
2. When the length of the main vine is 1.4- 1.5m, cultivate the top secondary branches to promote the growth of the main vine. When the length of the main vine is 1.6- 1.7, the top secondary branches are removed, and the top secondary branches are kept 1 leaf, and the remaining leaves are repeatedly cored. The winter scissors are carried out according to the old rules.
2. The pruning method of Kyoho grape seedlings in the second year is as follows:
1. Leave no branches within 50cm from the ground on the main vine of the shed, and leave more new branches above 50cm. When the new shoot length is 15cm, the branches with too long winter and weak top development should be shrunk. It is advisable to leave 6 new shoots per tree (bud spacing 15cm).
2. When the inflorescence size can be clearly identified on the new shoots, the redundant inflorescences should be thinned, leaving 4-5 inflorescences per plant. If there are many inflorescences, it is best to leave 1 ear per branch. Assuming that there are few inflorescences, you can leave two ears for the fruiting branches. When the new shoots of 2-year-old trees are 80cm long, 8- 12 leaves should be reserved for the final branches and 10- 12 leaves should be reserved for the vegetative branches 2-3 days before flowering or after the inflorescence at the initial flowering stage.
3. In winter, the length of the main pleat is slightly thicker than 1cm, and it can be chopped by 50-60cm. In addition, the mother branches will be pruned with short tips.
