What problems should be paid attention to in the practice of persimmon tree shaping?

Persimmon tree plastic trimming should pay attention to the following problems:

Young tree pruning: Persimmon tree young tree extension branches and development branches should be properly short-cut to enhance the tree potential. Slim branches, dense branches, cross branches, overlapping branches, etc., need to be cut off in order to reduce the useless consumption of nutrients and improve the ventilation and light transmission of persimmon trees.

Fruit tree pruning: Persimmon trees are prone to form "strong, weak, peripheral branches, canopy closed", so pruning is mainly to remove the pests, branches, branches, dense branches, etc. Extend the head and shorten it to increase the illuminance of the sputum in the fruit tree, and induce the internal sputum to induce new branches. The results of the 3-4 year old mother branch need to be thinned and renewed, which promotes the strong result of the mother branch. The pruning mouth is applied to the callus anti-corrosion film in time to prevent the pathogen from invading the wound and protecting the wound from healing.

Aging tree pruning: The purpose of aging tree pruning is to update the result branch group. The pruning should retract the big branch and promote new branches. The degree of retraction can be piled in the 5-7 year old part, and the long branches of the progeny are topped and matched with other pruning measures. , ability to restore results.
