Foolproof trimming method for Mopan persimmon trees in full bearing period

Abstract

The invention provides a foolproof trimming method for Mopan persimmon trees in the full bearing period. The method comprises the following steps of: keeping the growth potential of perennial big branches; thin-removing all annual branches, of which the growing length is less than 15cm; keeping branches uncut at an interval of 20 to 25cm for the annual branches which horizontally grow or obliquely grow and of which the growing length is more than 15cm, wherein vigorous branches and moderately vigorous branches are kept and thin and weak branches are thin-removed; thin-removing branches without a growing space from the base for upright water sprouts of which the growing length is more than 15cm; for the upright water sprouts of which the growing space is 20 to 60cm, cutting off four-fifths of or cap-trimming the branches; and for the upright water sprouts of which the growing space is more than 60cm, keeping two-thirds or three-fourths of the braches so as to promote branching and culture bearing branch groups. The trimming method has the advantages of simple operation, simple large-area popularization, stable yield and high efficiency, and meets physiological requirements of the Mopan persimmon trees in the full bearing period.

Description

Technical field: [0001] The invention belongs to a pruning process of fruit trees, in particular to a fool pruning method of Mopan persimmon trees in full fruit stage. Background technique: [0002] Mopan persimmon (also known as Gai persimmon) is the main persimmon species in North China. [0003] Most of the traditionally planted Mopan persimmon trees are planted in the form of large crowns and sparse planting. The trees are tall, extensively managed, and tree vigor is weak. No one pruned the persimmon trees before the 1960s. In the mid-to-late 1960s, due to the development of production and technology, Mopan persimmon pruning technology began to be popularized. At that time, the pruning method was mainly adopted, such as big fall, big cutting and thinning, retracting large branches, which played a role in stimulating the growth of Mopan persimmon trees and restoring tree vigor. It has a very good effect. At the same time, the phenomenon of bare legs and top fruiting has ...

Problems solved by technology

[0003] Most of the traditionally planted Mopan persimmon trees are planted in the form of large crowns and sparse planting. The trees are tall, extensively managed, and tree vigor is weak. No one pruned the persimmon trees before the 1960s.

In the mid-to-late 1960s, due to the development of production and technology, Mopan persimmon pruning technology began to be popularized. At that time, the pruning method was mainly adopted, such as big fall, big cutting and thinning, retracting large branches, which played a role in stimulating the growth of Mopan persimmon trees and restoring tree vigor. It has a very good effect. At the same time, the phenomenon of bare legs and fruiting at the top of the tree has been initially solved. However, due to excessive pruning, the tree body is too long and the phenomenon of stripping is also caused. The persimmon trees are still more serious in the next year.

However, the defect of Mopan persimmon pruning technology is that it is too meticulous, and it is difficult for fruit growers to master
