When will the vine be trimmed? What are the pruning standards?

The pruning of the vine is very important, it can adjust the water and nutrients of the vine, it has to be pruned all the year round, so when will the vine be pruned? What are the pruning standards?

When will the vines be pruned

It is usually pruned one month after the fallen leaves, when the nutrients have been returned to place. However, it is necessary to see whether the varieties are resistant and whether they can survive the winter safely, such as red grape, Crisen, Golden finger, White Rooster Heart and so on. All need to bury the soil to prevent the cold, the pruning time should be advanced or pruned with leaves, at the end of November or early December, bury the soil after pruning to prevent winter damage. Other varieties are generally trimmed from December to January.

A long time ago, people did not master enough grape pruning technology, generally using winter pruning, while ignoring the four seasons pruning, now changed the old concept, using new pruning techniques, engaged in four seasons pruning, to solve the problem of lighting and shelf closure. Reasonable control, conservation, use, supplement, consumption, so that the tree to achieve a balanced state of nutrition.

1. Pruning in Chung season. That is, the method of wiping buds in Chung season, erasing multiple buds, thin buds, sprouting buds, playing a role in saving nutrients, so that all nutrients are supplied to the retained buds, commonly known as conservation.

2. Summer pruning. The results showed that the branches and vegetative branches were heart-picked, slightly treated, pinched, followed by ear shaping, ear thinning, grain thinning and so on.

3. Pruning in autumn. The task in autumn is to pick the heart for the second time, remove the airtight branches, thin and weak branches, and the branches with low Lignification, adjust the number of branches, see the light of the branches, improve the lighting conditions, and make the shelf surface permeable.

4. Winter pruning. Winter pruning of grapes has the largest amount of pruning and the largest number of branches removed. Winter pruning is an effective method to determine the yield in the coming year.

II. Pruning standard

It is determined according to the characteristics of the variety, tree strength, tree age, frame type and yield. There are thinning pruning, short pruning, medium pruning, long pruning, super long pruning, double branch renewal, single branch renewal.

1. The method of thinning: it is to remove the weak branches and useless branches.

2. Short pruning method: that is, 2mur3 buds pruning, which is aimed at the newly loaded young trees for flat stubble pruning.

3. Medium pruning method: 3 medium pruning 5 buds pruning, for missing plant parts, medium pruning is used to increase the number of branches and leaves in order to fill the space.

4, long slightly pruned and super-long slightly trimmed 6 Mel 12 buds, which are generally used to extend the main vine, for example, the main vine cultivated in a small shed needs to extend the upper shed.

5. Double-branch renewal: on the basis of last year's pruning, two buds are kept on each of the two branches for pruning. However, double-branch renewal needs to be carried out in the case of space in the main vine, otherwise the shelf surface is airtight, invalid leaves increase, resulting in nutrient consumption.

6. Single branch renewal: that is, the original double branch is cut off, one branch is retained, and the retained branch is truncated, which is called single branch renewal.

7, big renewal and small renewal: big renewal is to cut off the old vine from the base, retain a sprouting branch, and cultivate it into a fruiting mother vine. Small update is to replace the weaker branches with the strong ones. Keep the tree young forever and prolong the fruiting life.

The pruning of the vine should pay attention to the smooth cut and be sure to protect the wound.
