As the Lidong Festival has passed, the temperature in various places has gradually dropped, the grapes have basically been harvested, and the grape winter cutting is about to begin. Winter pruning is an important part of the four annual grape pruning. Its purpose is to maintain the shape of the tree, regulate the relationship between tree growth and fruit, improve the ventilation and light conditions of the tree, and adjust the position of the parent branch of the fruit to prevent fruit. The parts are moved out, so that the fruiting mother branch is constantly renewed and rejuvenated, laying a good foundation for the yield and quality of grapes in the coming year. Cutting grapes too early or too late in winter will cause them to lose a lot of storage nutrients, which is not conducive to the next year's germination, inflorescence supplement differentiation and new shoot growth. The best period for winter pruning is from 10-15 days after leaf fall to one month before the wounding period of the following spring. After entering the wounding period, pruning must not be repeated. Because winter shears need to cut off a large number of branches, the nutrient loss of the pruned branches must be considered. Pruning wounds in different years should be kept on the same side of the main vine as much as possible, so as not to affect the transportation of nutrients and water in the tree. The cutting length of branches and vines depends on the characteristics of the variety and the growth of the vines and the conditions of fertilizer and water. For example, longan, etc. have strong growth potential, strong branches, weak flower bud formation ability, and late results. Pruning with medium-length shoots can be used to retain 5-9 buds; Rose incense, giant peaks, etc. are medium-growing and easy to bloom. They can be pruned with medium and short shoots, and 3-5 buds are retained. For bare branches, it can be retracted to the new shoots that sprouted from the bottom. If there is no new shoot, it can be retracted according to the occupied space to promote the sprouting of new shoots. When short-cut pruning, cut at the middle or upper part of the knots. This is conducive to the germination and growth of top buds. "Four-side" trellis grapes generally adopt the shape of dragon vines (dragon stems), and their pruning is very regular, that is, within 1 meter of the main vine, 3 fruiting branch groups are reserved, and each fruiting branch group retains 2 fruiting mothers. There are 6 fruiting mother branches in total, and each fruiting mother branch is cut to leave 2-3 buds, and 9-12 new shoots are selected in spring, so it is also called "1, 3, 6, 9-12" pruning method. The pruning method of the dragon vine tree shape is as follows: During the growth period, one main vine must be cultivated for the grape plants with a diameter of more than 1 cm. In order to prevent overgrowth and promote the main vine to be full, when the new shoot grows to 1 meter, top off the center. After the secondary shoot germinates, except for the top 1-2 not topped, the other secondary shoots are left with 1-2 leaves topped. When cutting in the winter, choose a place near the topping of the main vine to leave full buds. For the new shoots from the remaining buds, 1-2 flower spikes are left on the thick branches, 1 on the medium branches, and no weak branches. Use fruit to adjust the tree vigor to make it grow normally, and remove the fruiting branches when cutting in the next winter. Let the prep branch become the fruiting mother branch. Results The mother branches were mostly pruned with short shoots (remaining 2-3 buds) and ultra-short shoots (remaining 1 bud). In the summer of the third year, cut off the new shoots at the base of the parent branch and leave the inflorescence as a preliminary branch; select the new shoots at the front of the parent branch and let it bear fruit. In the fourth year, the main branch group is renewed to prevent the branch group from moving out, disturbing the tree shape and blocking the light. Dragon vine tree pruning should adopt the "single branch renewal" method, that is, pruning the mature branches and vines with 2-3 short shoots during winter pruning. The short shoots left behind are the result of the following year's mother branch. It is an update branch. Disclaimer: Some articles on this website are transferred from the Internet.
