Problems solved by technology

[0005] The space utilization of the above tree shape is large, which is conducive to high yield, but it has the following disadvantages: (1) Due to the large tree body, the shaping period is long, and the tree body is formed slowly.
(2) There are many levels in the tree skeleton, and the latent buds and adventitious buds on the backbone branches are easy to sprout. There are many branches on the back, and measures such as frequent topping and bud wiping are required for management, which requires a large amount of labor
(3) The crown volume is large, the peripheral branches and leaves are large, and the leaf curtain layer is thick, resulting in very little light exposure to the leaves in the inner chamber, which is not conducive to ventilation and light transmission, especially the inner chamber is not easy to spray chemicals.
(4) And the traditional tree shape generally takes 5-6 years, and the forming time is long

Embodiment 1

[0070] Example 1: Method for dendritic cultivation

[0071] Time: March 2018-August 2020

[0072] Test material: new strains of wolfberry 14-104, 16-23-7-8

[0073] In March 2018, the fence frame was set up: a triangular iron bracket was buried every 10.0m in the planting row, height: 2.2m, buried 0.6m underground, and fixed with reinforced concrete. Holes are drilled on the iron frame at intervals of 0.4m, 1.0m, and 1.6m from the ground, and the traction steel wire is used for hanging drip irrigation pipes and tying upright bamboo poles to fix the trunk.

[0074] Planting of seedlings in April 2018: Plant wolfberry seedlings according to the row spacing of 2.5m and the plant spacing of 0.5m. At the same time, the trunk is tied, and the trunk is tied and fixed to the bamboo pole, so that it can grow upright and avoid being broken by the wind.

[0075] After the seedlings survived in May 2018, cut off the stem at a distance of 90cm from the ground, cut off the branches that s...

Embodiment 2

[0079] Example 2: Method for dendritic cultivation

[0080] Time: March 2019 - August 2020

[0081] Test materials: The new annual Lycium barbarum strains 14-104 and 14-87, which were planted in 2018, were used as test materials. The tree shape is a single trunk shape, compared with the two-layer natural semicircle used in production.

[0082] Trunk tree cultivation method:

[0083] In March 2019, the trunk was cut short at 90cm, and the branches that sprouted under the cut for about 15 days were shortened, and one branch with strong growth potential was selected. Topping when it grows to 1.6m, branches above 90cm from the ground are not treated, buds below 90cm from the ground are removed in time, and the number of branches on the central stem is 23-24.

[0084]

[0085] Before spring germination in March 2020, thin out weak branches, diseased branches, and overly dense branches in the central trunk. Before budding in spring, the main branches in the middle and lower pa...

Abstract

The invention provides a cultivation method for a trunk-shaped Chinese wolfberry tree form, and belongs to the technical field of Chinese wolfberry tree shaping and pruning. The cultivation method comprises the following steps that a hedge frame is arranged; seedlings are planted; and shaping is carried out for three years. The center trunk of the tree shape cultured by the method is topped once during shaping in the first year, is not layered, has many main branches, only needs 3 years, and the tree body is basically shaped, which is 1-2 years earlier than that of a traditional tree shape.

Description

technical field [0001] The invention belongs to the technical field of medlar tree shaping and pruning, and in particular relates to a method for culturing a medlar trunk-shaped tree. Background technique [0002] Tree shape is an ideal tree skeleton structure model created by people in the long-term production practice according to the law of fruit tree growth and development. In the production and cultivation of fruit trees, the first consideration is how to build a garden and which tree shape to choose. The selection of tree shape is undoubtedly one of the important conditions to ensure high-quality, high-yield and efficient fruit production. In production, it is often necessary to select different tree shapes and corresponding shaping and pruning methods according to the different growth habits and cultivation requirements of different tree species, so as to achieve the ideal The group structure, large source and reservoir, and high utilization rate of light energy lay ...
