As the temperature drops, the vines begin to enter a dormant period, a time period that is crucial as it prepares for next year. During this dormant period, the vines store nutrients such as sugars and proteins produced by the leaves, and as the temperature drops, the starch is gradually converted into sucrose and glucose. This transformation takes place only in the upper part of the ground that is exposed to low temperatures, and there is little change in the roots.
But even during the dormant period, the roots absorb nutrients from the soil, and although there are not many of them, the vines are still truly year-round. During this period, farmers need to summarize and analyze this year's production, so that they can take more effective improvement measures next year, reduce unnecessary losses, and ensure a bumper harvest. However, one cannot sleep with the vines, because winter pruning is very important. Winter shearing is related to next year's harvest and **, so special attention is required.
The exact pruning method depends on the variety, the position and the fertilizer and water conditions. Different varieties and growing environments require different pruning methods. For fruit-bearing varieties and dense planting and trellis cultivation, short and medium tip pruning should be the mainstay;For varieties with weak germination and poor fruiting performance, as well as sparse planting and trellis cultivation, medium and long tip pruning should be the mainstay.
Extra-short tip pruning is a very good pruning method, but it should be noted that the leaves are well protected and cannot be damaged by pests or other problems such as typhoons. If there are not enough leaves, you can selectively leave the middle or long tips to prune to ensure a good yield the next year. Branches that are too dense will lead to insufficient nutrient accumulation, poor fruit quality, and difficult to produce high-sugar and fragrant fruits. Thinning of the branches can lead to physiological diseases such as sunburn and airburn.
Ultra-short tip pruning keeps the fruiting branches short, and the extracted shoots are close to the main vine, which can control the outward movement of the fruiting parts, so that the nutrients stored in the vine are concentrated, the new shoots grow robustly, and the flower buds are easy to form. When pruning ultra-short tips, there are some important points to pay attention to: clean up the dry residue pile, leave a small section of protective pile, to ensure that the medulla of the section does not lose water, and the branches can not be moved outward, to increase the effective leaves, each fruiting branch to ensure that there are enough 18-22 functional leaves, so as to produce high-quality fruits.
In short, during the dormant period, the vines undergo a series of physiological changes, so farmers need to pay special attention to their winter pruning. Only through scientific management measures can we ensure a bumper harvest next year. Winter is an indispensable time in the vineyard and requires a series of maintenance tasks, including pruning, clearing and watering frozen water. These are very important tasks that are directly related to the growth and harvest of the grapes and need to be taken seriously.
First of all, pruning is the highlight of the vineyard winter. The purpose of pruning is to control the momentum of the tree and promote the growth of the fruit. Pruning requires those that are thinner than 08 cm, thicker than 1Cut off 2 cm shoots, as the flower buds produced by these shoots are of high quality. At the same time, it is necessary to prune the medium and long tips to achieve the purpose of adjusting the tree strength and enriching the full buds. However, mid-to-long tip pruning requires skillful technique and is prone to uneven strength. Therefore, great care needs to be taken when pruning.
Secondly, it is also indispensable to clear the garden in winter. Clearing the branches should be the first priority. The pruned branches should be cleared out of the orchard in time and destroyed outside. At the same time, it is necessary to scrape off the old warp skin and eliminate the diseases and insects that overwinter under the old warp skin. In addition, eggs from the trellis need to be completely removed. Some pests, such as the spotted wax cicada, lay their eggs on grape trellises. Cleaning these eggs can reduce the number of pests and help in the later stage of pest control.
Finally, pouring frozen water is also a work that needs to be paid attention to in winter. In the northern provinces, it is necessary to permeate the soil once before it freezes. The permeability should seep below the distribution layer of the root cluster to ensure the safe wintering of the grapes. Permeability also prevents drought in early spring and also plays an important role in growing fruit in the second half of the year. In addition to the above, some incremental work can be carried out in winter, such as planting green manure crops under the grape trellis to improve the fertility of the soil and maintain soil moisture.
At the same time, it can also be applied to the branches to prevent the occurrence of pests and diseases. In short, winter is an important time in the vineyard and requires important tasks such as pruning, clearing the vineyard and watering frozen water. All this work is done to ensure that the grapes grow healthily and lay a solid foundation for a good harvest in the future. While carrying out these works, it is also necessary to pay attention to the development of incremental work to improve the quality of the grapes and the benefits of the harvest.
