Problems solved by technology

This cutting method has three disadvantages: (1) only use the strong top to bear fruit, and chase outwards every year, and the fruiting part moves outward to the top of the branch
(2) There are no fruit branches in the inner chamber to occupy space, resulting in waste of space, low output and poor quality
(3) The tree is tall, labor-intensive and unsafe to operate
This method of shearing has three disadvantages: (1) it does not utilize the strong and fruiting mother branch to bear fruit, the yield is low, and the fruit quality is poor
(2) As a result of cultured with elongated branches in the inner chamber, the branch group enters the fruiting period late, and the large branch group occupies a large space, which affects the illumination of the inner chamber, resulting in low yield and poor fruit quality.
(3) The tree is tall, labor-intensive and unsafe to operate
It has three disadvantages: (1) Some varieties are not suitable for
Varieties that are easy to flower show high yield and good quality, while some varieties with poor flowering ability have no fruiting ability in the developed branches that year, resulting in low yield
(2) This pruning method requires high fertilizer and water management conditions
(3) The technology is complicated, it is not easy for fruit growers to learn, and it is difficult to master the scale
If the weight is cut, the yield will be low, and if the weight is cut, the quality of the fruit will be poor, and sometimes the phenomenon of large and small years will appear.

Embodiment 1

[0033] A chestnut control large tube small alternate update rejuvenation pruning method, the specific steps are as follows:

[0034] 1. After the chestnut tree is grafted into a cultivated variety, remove invalid large branches: according to the requirements of plastic surgery, select and retain the main branch, side branch and fruiting branch group, and control the reasonable tree height.

[0035] 2. When pruning in the first year, remove the strong branches at the top, keep 2 strong branches in the horizontal direction for fruiting in the same year, and remove all the weak branches below, that is, the so-called control of large and small, specific pruning methods see Figure 1a-1b .

[0036] 3. When pruning in the second year, remove the strong branches at the top of the two fruit-bearing branch groups, keep the two strong branches in the horizontal direction, and remove all the weak branches below; The other one retains 2-4cm at the base and keeps the prongs, which can pr...

Abstract

The invention discloses a method for rejuvenating and rejuvenating pruning of chestnut by controlling large and small tubes alternately, and belongs to the field of chestnut tree pruning. The pruning method disclosed by the invention includes controlling the number of large branches, removing prosperous branches at the top, retaining relatively strong fruiting mother branches, and removing weak and redundant ineffective branches; leaving two parallel strong fruiting mother branches in the front branch group, and leaving a 2-fruit branch in an adjacent position. 4 cm of renewal pegs are used to promote the development of branches for the next year; after 3 consecutive years of fruiting and cultivation, the excessively long front-end branch groups are pruned and retained to promote the growth of developmental branches for the next year. The invention can save nutrients, rejuvenate the tree vigor, and can realize the free expansion and contraction of the crown, the inside and outside of the crown can transmit light, and there are fruiting mother branches inside and outside, so as to achieve the purpose of three-dimensional results.

Description

technical field [0001] The invention belongs to the field of chestnut tree pruning, and in particular relates to a method for alternately renewing and rejuvenating chestnuts by controlling large tubes and small tubes. Background technique [0002] Chestnut is one of the main woody food tree species in my country. However, due to its biological characteristics such as light-loving, apical dominance, and strong branching power, it is easy to make the canopy closed, resulting in insufficient light and ventilation inside the canopy, resulting in the fruiting of the canopy. The phenomenon of outward migration reduces fruit yield and quality, resulting in economic losses. Pruning in winter can adjust the structure of the tree, adjust the internal light of the canopy, and adjust the distribution of nutrients among various organs, etc. The ventilation and light transmission conditions in the canopy with different pruning intensities are different, resulting in differences in temperat...
