Embodiment 1

[0029] A method for pruning thin-shell pecans throughout the year to cultivate a large number of fruiting branches, the process flow chart is as follows figure 1 As mentioned, the specific steps are as follows:

[0030] (1) On December 26, 2009, 1 / 2 short pruning was performed on 70 thin-shelled hickory 'Mahan' 5-year-old saplings with long branches (length greater than 100cm), and medium-length branches (50-100cm) 1 / 3 short pruning, slow release of thin branches.

[0031] (2) On March 18, 2010, girdling was carried out on the relatively upright long branches with a diameter of 1.5 cm or more of the whole plant, and girdling was carried out on the prosperous long branches with a diameter of 1 cm-1.5 cm.

[0032] (3) On June 16, 2010, remove 1 / 3 of the entire length of the erect and prosperous new shoots of the whole plant that are more than 50 cm long.

[0033] (4) After short pruning in winter, apply 20kg of chicken manure and 2kg of slow-release fertilizer to the soil of e...

Embodiment 2

[0037] (1) On December 20, 2010, 1 / 2 short pruning was carried out on the long branches (length greater than 100cm) of 70 thin-shelled pecan 'Mahan' 5-year-old young trees, and medium-length branches (50-100cm) 1 / 3 stub trimmed.

[0038] (2) On March 10, 2011, girdling was performed on the relatively upright long branches with a diameter of 1.5 cm or more, and girdling on the vigorous long branches with a diameter of 1 cm-1.5 cm.

[0039] (3) On June 15, 2011, remove 1 / 3 of the entire length of the erect and prosperous new shoots of the whole plant that are more than 50cm long.

[0040] (4) After short pruning in winter, apply 30kg of chicken manure and 2kg of slow-release fertilizer to the soil of each tree (produced by Scotts Company, trade name "Aolu 5", composition: nitrogen: phosphorus: potassium molar ratio: 14: 13:13. Slow-release period: 5-6 months); after pruning in spring and summer, compound fertilizer (any brand available in the market) should be applied to each t...

Embodiment 3

[0044] (1) On December 24, 2011, 100 thin-shelled hickory 'Mahan' 5-year-old saplings were trimmed to 1 / 2 for long branches (length greater than 100cm), and medium-length branches (50-100cm) 1 / 3 stub trimmed.

[0045] (2) On March 15, 2012, girdling was performed on the relatively upright long branches with a diameter of 1.5 cm or more, and girdling on the long branches with a diameter of 1-1.5 cm.

[0046] (3) On June 14, 2012, remove 1 / 3 of the entire length of the erect and vigorous new shoots of the whole plant with a length of more than 50 cm.

[0047](4) After short pruning in winter, apply 40kg of chicken manure (any brand available on the market) and 2kg of slow-release fertilizer (manufactured by Scotts Company, trade name "Aolu 5", composition: nitrogen: phosphorus: potassium) to the soil of each tree The molar ratio is: 14:13:13. Slow-release period: 5-6 months); after pruning in spring and summer, each tree is topdressed with compound fertilizer (any brand availab...

Abstract

The invention discloses a method for yearly pruning apocarya for multiple bearing branch cultivation. The method comprises the steps that in the last ten-day of December, long branches (longer than 100 cm) of whole apocarya saplings growing for five years are pruned one second shorter and medium length branches (longer than 50 cm and shorter than 100 cm) are pruned one third shorter; in the middle ten days of March of the second year, long vertical branches with the diameter lager than 1.5 cm are girdled and prosperous branches with the diameter larger than 1 cm and smaller than 1.5 cm are ringed; in the middle ten days of June, one third of a whole shoot of each new vertical prosperous shoot of each tree higher than 50 cm is removed. A whole set of pruning measures are conducted on the saplings growing for five years and fertilizer and water management and disease and pest control are conducted in cooperation after the branches are pruned, multiple bearing branches of the apocarya can be cultivated in the third year.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and relates to a year-round pruning method (short cutting in winter + girdling of branches in spring + topping in summer) for cultivating a large number of fruiting branches. Background technique [0002] The invention relates to a year-round pruning technology for cultivating a large amount of hickory fruiting branches, including three technical steps of short-cutting in the winter of the current year, girdling and girdling of the branches in the spring of the second year, and topping in summer. [0003] Thin-shelled pecans generally form female flower buds from the terminal buds of short branches (less than 30cm in length). At present, although hickory nuts have been grafted into seedlings to build orchards in China, the management of hickory saplings is relatively extensive, and they are basically not pruned. Fruits are usually seen in 7-8 years, resulting in high production costs and low...
