How to prune grapes in winter Do grapes need to be pruned?

How do you prune the Sunshine Rose seedlings in winter? These tricks are easy to learn.

Grapes need to be pruned when planting, and proper pruning can also increase the amount of fruit in the later stages, usually by wiping off the thin buds on the plant when the grapes first sprout, and when the grapes have flowered, the young shoots on the new shoots need to be cut off. When the fruit is ripe, it is necessary to cut off overgrown and diseased branches on the plant, and to prune the dead leaves regularly during planting.

Grapes are one of the common fruits in life, many people don't know whether they need to be pruned to grow grapes, in fact, they need to be pruned, proper pruning of branches can prevent branches from growing, and can also increase the amount of fruit in the later stage. Growing grapes requires multiple pruning of the shoots, and the thin buds can be wiped out when the grapes first sprout.

After the grapes bloom, you can cut off the shoots on the new shoots, and the main thing is to cut off the buds on the plant that are not growing well, leaving only the healthy main shoots; After that, the overgrown and diseased branches of the plant need to be cut off when the fruit is ripe, and the wilted leaves of the plant should be pruned regularly during the grape planting.

After each pruning, it is not possible to water and fertilize, when the plant is weaker, watering and fertilizing will be counterproductive, and it is best to do it on a sunny day when pruning, which is conducive to wound recovery. Later, after the plants recover their vitality, they should be watered and fertilized regularly to supplement nutrients to the plants, and disease prevention and control should be done in advance during the planting period.

Grapes have strict water requirements, so you don't need to water too much at the beginning of planting, and you should increase the number of waterings when you reach the growing and flowering periods. If you want grapes to bear more fruit, you should let the plants receive enough light when planting, but when the sun is strong, you should still give the plants proper shade, otherwise the plants will be sunburned.

In the case of pruning, one of the two mature branches on the vine needs to be pruned to promote the germination of new branches; Budding pruning, for the retained branches, it is necessary to cut off 3 cm, and prune off the thin branch buds germinating at the top to reduce unnecessary nutrient consumption; To prune weak branches, it is necessary to prune the diseased branches, diseased branches and yellowed branches in time to reduce unnecessary nutrient consumption.

When pruning the vines in winter, it is necessary to prune off one of the two mature branches on the vine to promote the germination of new branches, so that the nutrients can be concentrated in the growing and robust branches, so as to improve the yield and quality of the fruit. If there is only one branch, it is necessary to prune it in short sections to prevent the branches from growing long.

For the remaining branches, it is necessary to shorten 3 cm to promote the germination of new shoots, and it is also necessary to prune off the thin branch buds that germinate at the top of the branches to erase them to reduce unnecessary nutrient consumption. After pruning, carbendazim solution should be applied to the wound in time to reduce the growth of bacteria and allow the wound to heal as soon as possible.

During the winter season, it is also necessary to prune the weak branches, diseased branches and dead branches and leaves in time to encourage the vines to sprout new branches in the following year. After pruning, the wound can be coated with a layer of plant ash and wrapped in a plastic film to allow the vines to grow healthily.

Note that winter pruning should be done 1 month after the leaves have fallen and not from the base. After pruning, the plants need to be moved to a ventilated and cool astigmatism environment for maintenance, and the soil should be piled up near the root system to keep the soil temperature constant, so that it can resume growth as soon as possible.

1. Cut off the branches in late autumn, among the many branches, according to the dense distribution of the branches, select the weak and thin branches in the denser places and cut them off, so that the remaining branches can be sparse appropriately.

Second, the large branches cut in late autumn, there will be branched branches on the main stem branches of the grapevine, according to the layout of the courtyard, you can choose the side branches to prune appropriately, which is conducive to the growth of the main stem branches.

3. The branches that need to be cut off by the grape vines, because the vines have begun to produce small grapes, so that the nutrients can meet the needs of the fruit, they must be constantly cut off.

Fourth, the grape fruit should be cut off or broken off from the newly grown branches or newly issued branches in the upper part of the branches, so as to facilitate the growth rate and fatness of the fruit.

Fifth, in the early spring of the grape vines in the bud or flowering season, it is the same as the same reason, prune the branches frequently, the vigorous period is generally about 10 to 15 days to prune once.

Here's how to prune grapes in winter:

Identify the mother branch

High-quality fruiting mother branches are dark in color and shiny, the branches are fully mature, and the base is 2 nodes thick. The branches are tortuous and extended, the internodes are short, the nodes are prominent and thick, the bud eyes are high and full, and the scales are tight. The cross-section of the branch is round, the xylem is developed, the pith is small, the tissue is dense, and there are no diseases and pests.

Trim length

The common ones are short shoots (2 3 buds), middle shoots (4 6 buds), and long shoots (more than 8 buds), and the length of the pruning is mainly judged by its growth potential, fruiting branch rate and the height of the flower bud growing parts. Under the same conditions, all the thick and well-maintained branches should be kept for a long time. The flower buds in the lower part of the weak branches are well differentiated and should be appropriately shortened; The extended number of search branches should be long, and the prepared branches should be shortened.

Trim position

The pith of the grape fruiting branches at the cutting position is larger, the tissue is looser, and the water is easy to evaporate, so the cutting should be 2 4cm away from the bud eye when pruning, so as to prevent the increase of dry branches caused by the evaporation of water in the bud eye area. The cut should be on the opposite side of the cut bud as much as possible.

The amount of bud retention

The main factors influencing the amount of buds left in winter pruning were the frame type, pruning method, tree strength, bud germination rate and the proportion of new shoots and fruiting branches. In the actual operation of winter shearing, the amount of bud retention is often determined according to experience, which is generally 1 times more than the amount of shoot retention on the shelf surface in the spring of the following year. If there are 15 20 new shoots on the surface of the hedge, the amount of buds left in winter should be 30 40, and the short shoots are pruned, and 8 10 mother branches are left.

The grapes are pruned in autumn and before winter as follows:

1. Thinning refers to the way to cut the entire branch (including annual and perennial branches) from the base. This method is mainly to control the number of mother branches, so that the whole tree body can maintain a state of rapid growth. The distance between the shoots is usually controlled at 18-20 cm.

The standards of thinning include overly dense branches, old and weak branches, long branches, diseased and insect branches, etc.

When pruning, attention should be paid to the cutting edge not to be too close to the mother branch, so as not to evaporate the wound water and affect the nutrient channeling of the mother branch. A large number of production practices have proved that the diameter of the grape branches is generally optimal when it is centimeters, and reaching such a thickness indicates that the vines are growing moderately.

Not only is the growth and development of the year balanced, but the acre branches also indicate that the grape flower buds are well differentiated, laying a solid foundation for the yield and quality of the next year. Therefore, when leaving branches, it is necessary to keep the branches of appropriate thickness (diameter and thickness cm), remove the branches that are too thick and too thin, and the thickness of the cut is generally not less than cm.

2. Shrinking pruning is a pruning method that prunes off a section of the infiltrated branches that are more than two years old and leaves a section. Its function is to renew the tree potential, cut off the branches that are aging, bent, blind and have reduced fruiting ability, so that the new branches are in an advantageous position, prevent the expansion and outward movement of the fruiting parts, and balance the tree potential.

Generally, the main vine will age after 10 years, and the main vine should be renewed in time and a new main vine should be cultivated to replace the old vine. However, it is necessary to pay attention to the smoothness of the saw edge to facilitate healing, and the wounds of different years should be kept on the same side of the main vine as much as possible to avoid causing wounds.

1. Branch pruning: remove one of the two branches around the old vine to promote the germination of branches. 2. Cutting branches and cutting buds:

Truncate the remaining shoots by 3 cm and erase the emaciated shoots at the apex. 3. Precautions: Pruning grapevines in winter should be carried out one month after the leaves have fallen, and it is not advisable to start pruning from the base to avoid damage to the plants.

1. Prune the branches

When pruning vines in winter, cut off one of the two mature branches around the vine to promote the germination of new branches, which is conducive to nutrient concentration and increase the amount of fruit.

2. Cutting branches and cutting buds:

For the retained branches, it is necessary to cut them short by 3 cm to promote the germination of new shoots, and to erase the thin young shoots germinating at the top of the branches to reduce nutrient consumption.

3. Precautions

Winter pruning of grapevines is best carried out after a month of defoliation, should not start pruning from the base, so as not to damage the vines, and in the process of pruning, the diseased branches, senescent branches should be cut together to improve the air permeability between the plants, after pruning the vines should also be placed in a place of astigmatism, which is conducive to wound healing.
