Winter pruning of grapes
If the premium grape varieties are planted for more than 5 years without care, they will be closed and the yield and quality will be worse than a year. In fact, the problem lies in the crowded, impenetrable, pruning. Here are the main steps of pruning. The winter shearing period should generally be carried out one month before the occurrence of the injury flow after the natural leaf fall to the next spring. As a result, the amount of pruning in the winter trimming of the mother twigs depends on the variety, the result habits, the planting density, the pruning form, and the like. Reasonable leave buds are the basis for promoting high yield and quality of grapes. According to the results of the three methods of pruning the mother shoots, 2-3 shoots were left for pruning, and 4-7 shoots were left for pruning in the shoots, and 8-12 shoots were left for pruning. The varieties with budding, fruitful varieties, and dense planting and kerf cultivation are mainly short- and mid-tip pruning; the varieties with weak germination power and poor performance and the cultivation of thin plants and scaffolds are mainly pruned by medium and long shoots. . Relatively speaking, the vigorous growth of trees, the thickness of their mother branches, and the fullness of buds can leave more buds. Generally, 12-15 buds need to be kept per square meter. Excess dense branches, thin branches, branches and branches, dead branches, and immature branches are all sheared off from the base and the rest are shortened as required. The large-grain grape varieties such as pruning giant peaks were updated, and as a result, the survival period of the branches was short, and the tree vigor was aging quickly. Must update the trim. One is the result of branch updates. Barely senescent shoots are generated on the base and heavy short cuts are performed to promote the germination of the basal buds. The second is plant regeneration. The perennial vines of the aging plants were cut off from the bases to promote the germination of the buds from the main vines on the bases, and the robust sprouts were selected and cultivated to become renewal and vigorous recovery. Pruning Precautions Keep the balanced distribution of the mother branches on the shelf surface, so that the light is evenly distributed; as a result, the mother branches are cut from the 2-3 cm section of the cut, and the clippings must not be too close to the shoots, so as not to cause clipping buds to die; Ensure that there are 2-5 robust and full shoots under the trimming of each result; trimming is too late. If you are experiencing a bad flow (cut out the mucus), you should trim the cut edge with a thin film to prevent the dead branches.
