Problems solved by technology

But this is only a light pruning, the pruning part is ≤ 1 / 3 of the branch length, and the potential for increasing yield is limited
Moreover, pruning should be started from the young forest period, and the effect will be slow; pruning needs to be carried out every year, and the lack of sunlight in the forest will affect the growth of trees to a certain extent.

Embodiment 1

[0029] Implement heavy pruning on 10-year-old citrus (ponkan) orchards.

[0030] 1. General situation of the orchard 10-year-old citrus orchard with an area of ​​1 mu and 50 trees. The canopy of the fruit trees is relatively large, partially overlapping each other, the light transmission conditions are poor, the canopy density reaches 0.8, the green leaf layer and fruiting parts move to the top, the middle and lower branches are thin and weak, and the orchard is in a state of premature aging. The peak annual yield of the orchard once reached 2,100 kilograms, which dropped to 520 kilograms the year before heavy pruning was implemented.

[0031] 2. Heavy pruning: When the citrus trees germinate in early April, saw off most of the main trunk and keep a height of 80-150 cm; leave 3 main branches, and keep a length of 30-50 cm after cutting. Cultivate the happy-shaped crown of the main branch.

[0032] 3. Gently cut and wipe the buds. After heavy pruning, keep 3 sprouts on each m...

Embodiment 2

[0036] Heavy pruning of 9-year-old Huyou

[0037] 1. General situation of the orchard 9-year-old pomelo orchard with an area of ​​0.5 mu and 22 trees. The orchard growth situation is similar to embodiment one, and the canopy density is 0.75. The annual fruit yield before heavy pruning is 300 kg, and the highest annual output is 1200 kg.

[0038] 2. Heavy pruning In mid-March, carry out heavy pruning before the fruit trees sprout, the method is the same as embodiment 1, but a small amount of green leaves must be kept on each plant after pruning.

[0039] 3. Gently cut moss buds with embodiment one.

[0040] 4. Fertilization management is the same as embodiment one.

[0041] 5. Orchard output After heavy pruning, the Huyou orchard quickly recovered. In the fifth year after heavy pruning, the fruit yield began to exceed the maximum annual yield before heavy pruning, and the average single fruit weight increased by 25%.

Abstract

A great pruning method for the (8-20)-year aged fruit tree in order to increase the yield of fruit and improve the quality of fruit features that whole fruit tree is greatly pruned in such manner that the upper part of its trunk is removed, only the lower trunk with 80-150 cm in height is retained, the 3-5 primary branches with 30-50 cm in length are only retained, and the new crown skeleton is re-modeled for improving the luminance and air flow.

Description

technical field [0001] The invention relates to a tree pruning method, in particular to a heavy pruning method for promoting young and middle-aged fruit trees to restore tree vigor and sustain high yield. Background technique [0002] The pruning that the present invention refers, is to cut off a part of fruit tree branches, and simultaneously includes the trunk content. [0003] The purpose of tree pruning is to obtain a good tree structure to adjust light, distribute nutrients reasonably, balance tree vigor, and increase yield. Among them, the pruning of fruit trees and economic forests is to increase the output of fruits and other products; the pruning of timber forests is aimed at increasing the output of the trunk part—that is, the volume of timber. [0004] The intensity of tree pruning is divided into three levels: light pruning - the cut part ≤ 1 / 3 of the branch length; moderate pruning - the cut part accounts for 1 / 3 to 2 / 3 of the branch len...
