Embodiment Construction

[0033] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] The present invention proposes a kind of pruning method that promotes walnut tree bore branch, comprises following pruning steps:

[0035] ① Determine the pruning object, pruning and pruning period

[0036] Pruning objects: According to the tree age, the pruning objects are divided into annual saplings, biennial saplings, three-year saplings, four-year-old primary-bearing trees, five-year-old fruiting trees and perennial scattered trees;

[0037] Pruning parts: according to the characteristics of the buds and the cultivation goals, determine several pruning parts on a complete branch;

[0038] Pruning period: the pruning period includes winter pruning and / or summer pruning;

[0039] ②Pruning operation

[0040] For young annual trees, set the trunk and cultivate the main and auxiliary branches;

[0041] For biennial ...

Abstract

The invention provides a pruning method capable of promoting walnut tree internal branching. The method includes: dividing to-be-pruned objects into annual young trees, biennial young trees, triennialyoung trees, quadrennial first-fruiting trees, fruiting big trees more than five years old and perennial scattered trees according to tree ages; according bud features and culture targets, determining a plurality of pruning parts on a complete branch; determining pruning periods which include winter pruning and / or summer pruning; pruning, to be more specific, for the annual young trees, determining a main branch and culturing the main branch and auxiliary branches; for the biennial young trees, expanding the crowns; for the triennial young trees, expanding the crowns and culturing fruiting branches; for the quadrennial first-fruiting trees, culturing extension branches or fruiting branch groups; for fruiting big trees more than five years old, culturing and rejuvenating fruiting branch groups; for the perennial scattered trees, culturing internal fruiting branch groups. The method has the advantages that fruiting parts cover the periphery and the interior, fruiting volume is increasedgreatly, three-dimensional fruiting is achieved, and fruit tree yield is doubled.

Description

technical field [0001] The invention relates to a pruning method, in particular to a pruning method for promoting inner bore branches of walnut trees. Background technique [0002] Walnut tree is an important ecological and economical tree species, which has been widely planted in our country. However, there are many differences in the planting and management of walnut trees, especially on the issue of pruning. Improper pruning often leads to disordered development of walnut branch groups, forming tall and empty tree shapes, moving the fruiting parts outward, reducing the fruiting volume, and forming low-yield orchards. Therefore, research invents a kind of pruning method that promotes walnut tree inner chamber to send out branches, promotes the balanced distribution of walnut tree body nutrition, cultivates inner chamber fruiting branch group, promotes flowering, improves yield. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention...
