What to pay attention to when pruning grapes
In recent years, the market demand for grapes has also been increasing, and therefore, the planting area has been expanding. More and more people are planting grapes, but many beginners do not understand the planting technology. The management of grapes is very important, directly affecting the yield, especially pruning. Proper pruning can improve ventilation. Today, the editor brings you the key points of pruning technology for grape planting, let's take a look together!
Pruning Time
Grape pruning time is divided into two periods, generally in autumn, winter, and summer. When pruning, the pruning time should be adjusted reasonably according to the planting area. In the north, due to earlier frost, pruning should start before the soil freezes. In the south, it is necessary to wait for all the leaves to fall and new buds to sprout. The pruning time should not be too late; if it is too late, it is easy to have a late spring cold phenomenon in spring. It can lead to grape bleeding, consuming too much nutrition. Summer pruning mainly involves wiping off the flower buds and thinning the branches.
Main Stem Pruning
In the south, after all the grape seedlings are planted in the same year, different specifications of main stems should be cultivated according to specific requirements. In the first year of planting, several different lengths of stems should be planted, then two main vines are planted at the top of the stems. When it grows to about 1 meter, the pinching work is done first, and then in winter, the main vine is cut at 90 centimeters from the top. If it is in the north, then we need to prune the stem to a 20-degree angle with the ground. After sprouting, the wiping work of the buds should be done, mainly within 50 centimeters of the stem.
Winter Pruning
In winter harvesting, strong main vines should be harvested at about 60-70 centimeters. For weaker main vines, adjustments should be made according to the actual situation. Then, the main grape vines are pruned. If there are not enough main vines in the current year, about three buds can be cut at the base of the one-year-old main vine. In the second year, the number of main vines is increased, and then a strong main vine is selected as an extension branch from the second year. In summer, the center of the main vine is pinched at about 0.7m.
Pruning Vigorous Trees
For vigorous grape vines, the lateral branches should be dealt with first, with the lateral branches left with about 5 buds for short cuts. If the growth is weak, the number of seed buds can be appropriately reduced to 3 to lay a good foundation for the cultivation of fruiting branches. In the second year, new main vines start to grow at the base, and in the third year, the lateral vines continue to grow. Then, branches and fruiting mother branches are cultivated in this way every year to ensure the overall uniformity of the shelf surface. When there are about three branch groups, the pruning work is basically completed. Later, the branches are cut long according to the length of the fruiting mother branches, maintaining the tree shape.
The above is a brief introduction to grape pruning technology. Pruning grapes is very important. It should aim to improve ventilation, promote flowering and fruiting, and increase yield. Today's introduction ends here, this article is for reference only, hoping it can be helpful to you!
