When is it appropriate to prune grapevines
Grapevine pruning is carried out to ensure a certain number of buds, regulate growth and yield, and thus ensure the annual production of good new shoots. Generally, pruning is done twice a year, once in winter and once in summer. During pruning, dead branches, diseased and insect-infested branches, useless secondary branches, and vigorous growth branches should be cut off, and fully matured, plump new shoots with full buds should be retained.
The function of pruning grapevines
Pruning grapevines ensures a certain number of buds, regulates growth and yield, and ensures the production of good new shoots every year, thereby increasing yield and achieving consecutive years of abundant harvest.The most appropriate month for pruning grapevines
It is better to prune grapevines in winter, as this allows for the习惯ual shortening of one-year-old new growth. This promotes growth. Grapevines need to be pruned twice because of frequent rainfall and rapid branching. Generally, pruning is done twice, once in winter and once in summer, which can promote more high-quality grapes on common branches. The most appropriate time for pruning grapevines for propagation is when the soil temperature reaches above 8-10℃ in early spring. Commonly used grapevine cuttings for propagation involve cutting one-year-old branches that are robust and have full buds. Cuttings, 5-15 cm long with single or double buds, are planted in the seedbed at a distance of 15cm×50cm in February.Methods for pruning grapevines
The general length for pruning is: short shoots, leave 1-24 nodes; medium shoots, leave 5-7 nodes; long shoots, leave 8-12 nodes. For mature and strong-growing new shoots, pruning can be slightly longer; for weak-growing, immature, and thin shoots, pruning should be shorter; for varieties with low fruiting ability at the base of the vine, medium to long pruning should be used. For sparse branches, longer pruning can be used to fully utilize space; for stricter summer pruning, short pruning can be applied, and for freely growing new shoots, longer pruning should be used.Precautions for pruning grapevines
1. The grapevine tissue is loose, with a large pith, and it is easy for water and nutrients to流失. When pruning, the cut should be made 3-5 cm above the bud at the top of the shoot or one node above the cut bud.2. During pruning, dead branches, diseased and insect-infested branches, useless secondary branches, and vigorous growth branches should be cut off. Long internode, small and sunken buds on vigorous branches can cause severe blind eyes and should be thinned or cut short, leaving fully matured, plump new shoots with full buds.3. When thinning branches, the cut should be controlled to be about 1 cm below the base and not close to the base. After the residual stump dries up, it should be cut off from there.4. For summer or winter auxiliary buds with a diameter of 0.8 cm or more and matured well, 2-3 nodes can be retained, while weak-growing ones should be cut off.If the specific content introduced above about when it is appropriate to prune grapevines can bring you help, remember to visit the website often!
