The video of grape pruning is as follows: Generally, the best time for grape pruning is in late autumn and before winter, which is about 65438+February. When the grapes are picked and the leaves fall, they should be trimmed. Grape pruning is usually carried out in summer and winter. The demand for pruning is greatest in winter, and the specific pruning time and method should be determined according to the local environment and climate. Different varieties of vines have different pruning methods. Pruning time of vines in winter can only store a lot of nutrients when pruning vines in time, which is beneficial to germination, inflorescence differentiation and new branch growth in the coming year. The best time to prune grapes in winter is about one month before the vines completely enter the dormant period and bleeding period. In addition, when pruning grapes in winter, the temperature drops obviously, so it is necessary to observe the time from half a month to one month after all the leaves of the vines fall off. The specific time for pruning vines in winter should be 5438+ 10 in the middle of June, and the specific pruning time can be adjusted according to local conditions. Precautions for pruning vines Try not to damage the main branches when pruning vines in winter. If the damage to the main branches is too large, it will not only easily lead to trunk rot, but also affect the growth and fruit quantity. Prune vines in winter. For weak branches, if there is still the ability to bear fruit, when there is no bud at the base, the main branches on the old branches can be shortened to help the weak branches grow stronger and balance the growth of trees. For old branches and vines, if they have no ability to bear fruit, they must all be uprooted. Pruning time of summer rattan can be divided into three times, and different pruning time and methods are also different. The first pruning is done before the buds germinate and the leaves unfold. At this time, we can see that some new buds grow on the weak branches pruned in winter, and some old branches will be at the base of some buds. At this time, you don't need any tools, just wipe it gently with your hands. For those buds on the shoots, the stunted buds can be removed at this time. The second pruning was carried out when about 7 leaves grew on the top of the new tree, which showed the size and strength of the inflorescence. In the specific operation process, pruning should be carried out according to the variety, soil, tree potential and planned yield to determine the number of new branches. The third pruning is carried out when the new branch is bound for the second time. The second pruning will leave more branches. This time, the treetops with inflorescences will be left and the rest will be removed.
