During the winter pruning period of grapes, Shandong Province is generally suitable from early November to mid-February in February, that is, 2-3 weeks after the fall to the spring before the occurrence of injury in 3 to 4 weeks. Pruning prematurely will affect the backflow of nutrients, and too late will be prone to injury. Injury will often affect the germination of the bud, affecting growth and results. Now mainly introduces the processing method when the grapes result in female winter cutting.
First, the length of clipping. When pruning, the branch should be selected for full growth, good maturity, appropriate parts, no pests, and no damage to the branches. It is required to cut at 1 to 1.5 centimeters on the shoots. The length of the dendrite usually remains as the number of remaining buds. Based on. Generally divided into short tip pruning (for the results of the mother leaves 1 to 4), pruning in the tip (cut 5 to 7 knots), long tip pruning (more than 8 knots) and mixed pruning (long tip, in the tip, Short tip trim). In the specific pruning should also take into account the grape varieties, dendrite growth strength and shaping methods and other differences. For example, rosettes are trimmed with short shoots, and the fruit setting rate is high, and the ear is more compact and uniform. While Kyoho and Longan grapes are higher in the flowering stage, the trimming of the shoots and shoots should be adopted.
Under the same conditions, where thick and good branches are to be kept for a long time, the flower buds in the lower part of the weak branches will be better differentiated and should be cut short; the longer branches should be kept longer, and the shorter branches should be cut short; With the long shoots, the middle tips or the long tips, the middle tips, and the short tips, the main ones are pruning; the long stem pruning is mainly the pruning of the short tips; the soil is thin, the fertilizer is not enough, and the dry areas are dominated by short tips. . In short, the method of pruning different dendrons on a certain plant or plant should be flexible, and the method of pruning mixed shoots, shoots and shoots should be applied so as to obtain a good production effect.
Second, the number of clippings. In winter pruning of grapes, in addition to a clear length of cut, the number of cuts of the resulting females should also be considered. If the number of female vines is small, the output will be affected by shortage of vines in the following year. If the amount of vines is too small, the vines will be crowded, the load will be large, the light will be insufficient, and the phenomenon of serious fruit drop will also affect the wintering. And the annual output.
Therefore, according to the management level of varieties, soil, fertilizer, and water, the length and quantity of winter pruning should be determined according to the planned number of outputs, the total number of resulting parental branches that should be left in the whole garden, and the number of resulting parental branches that each should leave. Completing the production plan will also enable the plants to grow robustly and produce high yields year after year. It is advisable to have about 1000 branches per mu in general productive gardens. The arrangement of the result branches must be uniform, and attention should be paid to the preparation of branches, and the adoption of the two-branch updating method or the single-branch updating method should maintain the growth potential and rotation results of the branches, so as to ensure stable and continuous production.
Third, cut the location and direction. The result is that the grape has larger pith part, looser tissue, and easier evaporation of moisture. Therefore, the cut should be 2 to 4 centimeters from the bud's eyes when pruning, in order to prevent evaporation of water from the buds and cause dry stems to increase; cut direction should be as far as possible. The opposite side of the bud.
Fourth, post-processing. After the grapevine is cut, it is necessary to combine the maintenance of the scaffolds and pull the upwardly growing parental branches into a horizontal direction, which can promote the emergence of new vines and multiple results at the base buds. The pruned litter, rot fruits, and intercroppings were removed from the park and burned.
