Problems solved by technology

At present, the general cultivation mode of pear trees adopts a variety of tree shapes such as evacuated layered, happy, V-shaped, and spindle-shaped trees. Due to the different management methods and the different branching and germination capabilities of different pear varieties, the cultivation modes are also different. In addition, most growers often focus on pruning and shaping in winter, which requires high technical requirements, heavy workload, and low early yield, which will bring certain financial pressure to the growers, and it is easy to cause disordered tree shape and out-of-result branches. Migration, low yield, irregular fruit size

Embodiment Construction

[0028] A kind of pear tree columnar shaping method that the present embodiment provides comprises the following steps:

[0029] (1) Whole ridge

[0030] First spread the decomposed organic fertilizer evenly on the ground, use agricultural machinery to plow 0.6-0.8m deep, and arrange the ridges with mature soil after deep plowing. The direction of the ridges is preferably north-south. The width of each ridge is 2-3m, 0.3-0.5m, the distance between the ridges is 3.5-4.0m, the length of the ridges is combined with the length of the shaped field;

[0031] (2) planting seedlings

[0032] Select strong, upright and strong pear seedlings with a seedling height greater than or equal to 1m. When planting, the distance between the pear seedlings is 0.8-1.2m;

[0033] (3) fixed dry

[0034] When setting drying, choose healthy buds with full bud mouth, no disease, and no insects to set drying. Shorten the buds at the m strong buds; leave the top buds after drying, and erase 2 to 3 bud...

Abstract

The invention discloses a columnar shaping method for a pear tree. The columnar shaping method for the pear tree comprises the steps that a trunk and a plurality of main branches growing on the trunk are cultivated; a first main branch grows at the position, with the height of 0.5-0.7 m, of the trunk, the remaining main branches upwards grow on the trunk in the spiral direction, the interval between every two adjacent main branches is 0.15-0.2 m, the length of each main branch is controlled to be 0.3-0.5 m or 1.0-1.2 m, and the angle between each main branch and the trunk is 60-85 degrees; a plurality of bearing branches and vegetative branches grow on each main branch, the ratio of the bearing branches to the vegetative branches is 3:1, and the length of the vegetative branches is controlled to be 0.5-0.8 m. The shaping method for the pear tree has the advantages of being small in crown, free of large main backbone branches, large in bearing branch group, high in space utilization rate, good in ventilation and light transmission, fast in forming, light in pruning amount, simple in pruning technology, mild in growth, easy to bear early and high in yield, high in fruit quality, convenient to mechanically operate and the like.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a columnar shaping method for pear trees. Background technique [0002] Because of its thin skin, crispy and juicy meat, rich and tender taste, and rich and sweet juice, pears have the functions of clearing the heart, nourishing the lungs, reducing fire, promoting body fluid, moistening dryness, clearing heat, and reducing phlegm. It is rich in protein, fat, and carbohydrates. , Potassium, sodium, calcium, magnesium, dietary fiber and other nutrients are deeply loved by the general public. At present, the general cultivation mode of pear trees adopts a variety of tree shapes such as evacuated layered, happy, V-shaped, and spindle-shaped trees. Due to the different management methods and the different branching and germination capabilities of different pear varieties, the cultivation modes are also different. In addition, most growers often focus on pruning and s...
