Pruning methods of Zanthoxylum bungeanum in different periods
1, young tree stage
1-3 years, at this time, plastic surgery is the main thing, and trees are naturally happy.
(1) clustering tree
From planting to germination, 3 ~ 5 branches with ideal orientation are selected as main branches (the base angle is about 60).
The opening angle of other branches is temporarily used to support the main branch, and it is removed when cutting in winter.
Select 3 ~ 4 lateral branches on each main branch, and the cultivation and selection of lateral branches are the same as those of natural plastic surgery.
Plastic surgery is completed in 3 ~ 4 years.
(2) The shape of natural happiness
The tree is divided into three main branches on the trunk, with two or three lateral branches alternately arranged on both sides of each main branch, and each main branch and lateral branch is equipped with large, medium and small branches to form a plump and balanced crown.
The tree shape conforms to the natural characteristics of pepper.
Before germination after planting, the stem was fixed, and when the main branch extended to 60cm away from the first side branch, the second side branch was cultured by coring.
30-40cm away from the first lateral branch, in the opposite direction, and so on, to cultivate the third and fourth lateral branches.
According to the size of the space, cultivate the middle branchlets.
For the extended branches of the main branch and other leafy branches, pick the core lightly in late May or early July, squat down the inner cavity branches and enrich the branches and buds.
2, the first fruit period
Pruning at the first fruit stage is to balance the tree potential and control the branches reasonably, thus increasing the yield.
The pruning method is: cultivating small and medium-sized fruit branches by light first and then shrinking.
That is, the second young shear 1 branch, and then retracted to form the middle branchlet group.
Fourthly, from late May to early July, the growth of new shoots was controlled by opening the angle and removing the core, which promoted fruit expansion, flower bud differentiation and nutrient storage.
3. Full fruiting period
In the flowering and fruiting period, if the branches are not pruned, the fruit trees are prone to malnutrition or poor illumination, the inner branches are prone to aging, and the fruiting parts move outward, and the base of the backbone branches will be exposed.
Pruning methods: First, the crown is high and the light is getting worse, so you should fall in time and be happy.
Recover weak backbone branches, concentrate nutrition and improve lighting conditions; The second is to pay attention to the cultivation, adjustment, renewal and rejuvenation of branches.
The third is to cultivate preparatory branches and publicize this year's achievements.
The method is: single branch regeneration or double branch regeneration.
Single-branch regeneration method is to cut off 1 branch at a proper position to promote its fruit and prepare for the next year's fruit.
In a word, in order to improve the yield and quality of Zanthoxylum bungeanum, farmers had better master professional Zanthoxylum bungeanum pruning methods. I hope this article is helpful to everyone.
