Persimmons spring branches clever winter shear

First, the pruning of long branches should generally be cut off in summer. If not pruned in time in summer, it must be cut off from the base in winter. If the growing part of the long branch is relatively empty, it can be cut short with a length of 20cm to 30cm to promote the hidden bud to germinate and grow into a fruiting branch.  2. Pruning of growing branches there are some delicate branches in the canopy of persimmon trees, which should be thinned during winter pruning. However, if the dioecious varieties are monoecious, the branches of "1 move 3" and 1 "2" should be retained properly. For normal growing branches, most of them are good fruiting mother branches, which should be cut short by 1 / 3 and 1 / 2 according to their growth potential, and too many branches should be thinned at the same time.  3. After pruning persimmon fruiting branches, most of them grow weakly. The fruiting branches should be retained according to their growth, and some of them should be treated as new branches.  4. Pruning of fruiting mother branches if there are too many fruiting mother branches and allow them to grow naturally, it is easy to lead to the phenomenon of big and small years; if there are too few fruiting mother branches, it will affect the yield of the current year. Therefore, for persimmon trees entering the full fruit stage, the control of fruiting mother branches should be taken as the main measure to adjust the size of the year. When cutting in winter, trees with good growth should be kept more and less cut, and trees with poor growth should be kept less and cut more. At the same time, the combination of flower thinning, fruit thinning and other measures in the coming year can also achieve the goal of balanced increase in production and overcoming big and small years. When persimmon trees enter the late fruiting stage, the germination of the top will fluctuate irregularly with the increase of tree age. Therefore, the fruiting mother branch should be renewed and pruned in time. During the renewal, the bud eye or branch tip near the fruiting mother branch was used to form a new fruiting mother branch, and then the single branch renewal method and double branch renewal method were used year by year to restore the tree potential and prolong the tree age.
