Adult trees with tall crowns or shaded branches put into production should be moderately retracted and pruned after defoliation in winter. Short branches should be used to prune dense branches, cross branches, clustered branches and diseased dead branches, so that the branches can be distributed reasonably and cut into reasonable tree potential.

Build a good skeleton to cultivate a tree shape, pay attention to the balance of branch strength and the subordinate relationship between main branches, pick the heart in time, and promote the growth and fruiting of mother branches. Fixed dry height 1.2m, and selected main branches according to tree structure. Less thinning, more cutting, more branches. It is necessary to combine winter and summer. When the flourishing branches grow to 20-30 cm, it is necessary to remove the heart, promote the growth of secondary branches, and cultivate the light branches as much as possible to prepare for early fruiting.

Principles of persimmon shaping and pruning

1, which meets the characteristics of persimmon trees.

Tangible and immortal, shaped with the tree; The tree potential is balanced, and the master and slave are distinct; Give priority to sparse, restrain the strong and help the weak.

2, suitable for site conditions

The fertile crown is large and evacuated, and the barren crown is small and compact; Slope crown height; In places with insufficient light, the main branches should be thin and the leaf curtain layer should be thin.

3, the tree is strong but not in vain.

Young trees expand the crown and bear fruit early; Results The mother branch was quantitative. Fruit burns when it sees light; As a result, the site is near the main branch.

Extended data:

Growth habits of persimmon trees;

Persimmon is a deep-rooted tree species and a positive tree species. It likes warm weather, plenty of sunshine and deep, fertile, moist and well-drained soil. Suitable for neutral soil, cold-resistant, but more resistant to barren, drought, saline-alkali soil.

Most persimmon varieties began to bear fruit in 3-4 years after grafting, and reached the full fruit stage in 10- 12 years, while the seedlings began to bear fruit in 5-7 years, and the fruiting period exceeded 100 years.

The pruning time of persimmon trees is:

Persimmon trees are transplanted about one week after defoliation in autumn (Lunan165438+1mid-October) or about half a month before germination in spring (mid-late March), and the survival rate is very high.
