The purpose of pruning trees is to cultivate fruiting branches and fruiting branches to prevent premature aging. Trim or cut off branches that have grown too densely, trim dead branches and branches with pests and diseases, and trim and cut off cross branches and bald branches. When picking persimmons, try to protect the fruiting branches. Don't cut off the whole fruiting branch, and don't hit the persimmon with a stick, which will hurt the tree and cause diseases and pests. Pruning young persimmon trees generally requires selecting the main branches, setting the opening angle, and pruning after laying the skeleton. When pruning, the dense branches and bare branches should be thinned out to promote the growth of branches and lay a good foundation for the results. The pruning of adult persimmon trees is combined with thinning and shrinking branches to cultivate new branches in order to promote the growth of branches and improve the ventilation and light transmission conditions of plants.
Persimmons are perennial fruit trees. Pruning is a necessary cultivation measure to keep its high and stable yield. If you don't cut down trees for many years, you can let them grow. Generally, trees are tall, with dense trunk branches, small drooping branches, many dead branches, bare inner cavities, weak trees, many long branches, few flowers, low yield and poor quality. Therefore, it is necessary to carry out targeted ground pruning and gradually change this situation. After defoliation in autumn and before germination in spring, winter pruning should be carried out. Trees with too many branches should be combed and trimmed every year, and the big branches should be evenly distributed without interference.
If the tree body is too high, it should be carried out in different years, improving the lighting conditions in the lower part, promoting the development of new branches, appropriately retracting, thinning branches, overlapping branches and drooping branches, and gradually raising the angle of main branches. For the big branch with drooping tip, it retracts at the bending part and raises the angle with the back branch. For weak branches, we should start thinning from dense branches to concentrate nutrients and promote the growth of the remaining branches. However, whether it is a big branch or a small branch, the number of thinning in one year should not be too much, and it should be reformed in different years. In addition to winter pruning, summer pruning should be carried out during the growth period. The lack of pruning in winter should be made up by expanding buds, removing stones and thinning branches, so as to promote the formation of flower buds, improve lighting conditions, be conducive to fruit coloring, increase fruits and improve quality.
