Problems solved by technology

[0003] Our country has mainly promoted the arborization and dense planting system. The tree shape adopts small canopy sparse layer shape, free spinner shape or improved spinner shape. Although these tree shapes are smaller than the evacuated layered tree crown, due to too many short cuts, the layer spacing is small , and because there are 3-5 large branches of the same age under the middle trunk, the phenomenon of neck jam is serious, and the tree shape is disordered in the peak fruiting period, resulting in closed orchards, poor ventilation and light transmission, low fruit tree yield, and poor quality.
In order to increase the yield, fruit growers have taken extremely complex and cumbersome technical measures such as carving, peeling, pulling, pruning in four seasons, digging roots and controlling crowns, but none of them have achieved the desired effect
In addition, due to the airtightness of the orchard, the spraying effect of the orchard is poor, the amount of application is large, the number of natural enemies is reduced, and there are hidden dangers in the quality and safety of apples.
In recent years, some areas in my country have tried to carry out thinning and tree shape transformation on canopy orchards. Through measures such as stem lifting, head dr

Embodiment 1

[0063] Such as Figure 5 The tree shape of an apple tree with two branches and one trunk is shown, including:

[0064] The height of the tree is 2.8-3.2m, the crown is oblate and conical, and the trunk height is 80-100cm from the ground. Two main branches extending to the rows are cultivated on the middle trunk. The two main branches can be forward or oblique. The horizontal angle of the branches is 180 degrees. On the two main branches, the long-axis fruiting branch groups with different sizes, medium and small are directly cultivated, and 20-30 branches are cultivated on the middle trunks of the upper parts of the two main branches. Small and medium-sized fruiting branch groups with 90 degrees and less than 130 degrees.

[0065] The base angle between the two main branches and the middle trunk is 70-80 degrees, the waist angle is 60-70 degrees, and the tip angle is 50-60 degrees.

[0066] Its shaping method is as Figure 1-5 shown, including the following steps:

[0067]...

Embodiment 2

[0094] The inventor establishes a test garden according to the technical scheme of the present invention in Wangya high-tech demonstration field, Gaocun Township, Wanrong County, Shanxi Province. The varieties are Liangxiang, Gala, and thick red Fuji, and SH6 is used to dwarf the middle stock, and the base stock is octagonal crabapple. The row spacing between plants is 1.5×5m, and the plants are planted in north-south rows.

[0095] Pruning in the first year: the fixed dry height is 1-1.2m, the direction of the 4th and 5th buds is selected between the rows, and the 2nd and 3rd buds are erased; some seedlings are not high enough, at the full buds of 60-70cm Short pruning, take or transfer branches from the opposite side in summer to control growth. When pruning in winter, except for the middle trunk, all other branches should be removed at the same root, and the stem should be re-set according to the height of the stem.

[0096] In the growing season, remove the buds below 80cm...

Abstract

The invention discloses a two-branch one-trunk forming and planting method and a reshaping method for apple trees, which belong to the field of fruit tree cultivation and fruit tree ecology. The two-branch one-trunk forming method for the apple trees comprises the steps of cultivating each tree as high as 2.8m to 3.2m, and cultivating two main branches extending towards between lines on a middle trunk above the ground by 80cm to 100cm, thus forming an oblate conical crown. The two-branch one-trunk forming and planting method realizes close planting in wide lines, facilitates mechanical operation and labor-saving cultivation, reduces the labor cost, has high yield and good benefits compared with other tree forms with main branches in beginning ten years, and promotes the development of the dwarf apple trees.

Description

technical field [0001] The invention belongs to the fields of fruit tree cultivation and fruit tree ecology, and relates to a tree shape with two branches and one trunk of an apple tree, a planting method and a shaping method thereof. Background technique [0002] Apple trees are light-loving trees, and the light received and distributed by the canopy have an important impact on the quality of apple fruit. It has always been an important topic in the field of planting to study the maximum balanced utilization of various tree shapes for daylighting and dense planting. Before the 1960s, the world's apples were dominated by arborization and sparse planting, and the tree shape was scattered and layered. However, there were disadvantages such as low early yield, tall trees, labor-intensive management, and difficult management techniques. Since the 1970s, the main producing countries in the world have generally implemented the dwarf dense planting system, and planted about 80-160...
