Embodiment 1

[0037] Seedling selection: Choose high-quality pear seedlings with a base thickness of more than 1 cm and a seedling height of more than 1 meter. The buds are plump, with more than 3 thick roots of 0.2 cm, and well-developed fibrous roots.

[0038] Planting: Dig a 0.8-1 meter square tree pit in advance, and apply about 100 catties of organic fertilizer base fertilizer to each pit. The depth of planting should be based on the depth of seedling production. After planting, it should be watered and solidified. The planting density is small crown or medium crown densely planted pear trees with a row spacing of 2-4×4-5 meters.

[0039] (1) Pruning in the first year: pruning at 0.8-1.0 meters to fix the dryness, and carving the 3rd-5th buds under the cut;

[0040] (2) Pruning in the second year: After the first year is fixed, 2-4 branches will emerge from the cut; leave 40-50 cm for the central main branch to cut short, and carve the 4-6 buds under the cut Buds; if the length of th...

Abstract

The invention discloses a multi-main-branch open center tree shape of a pear tree, and belongs to the field of pruning of fruit trees. The trunk height of the tree shape is 0.7 to 0.9 meter, the central trunk height is 1.7 to 1.9 meters, 7 to 9 main branches are uniformly grown on the central trunk, and medium and small branch groups are directly grown on the main branches; the angle between each main branch and the central trunk is 70 to 80 degrees; and the thickness of a leaf curtain is 1.8 to 2.3 meters, and the height of the tree is 2.2 to 2.7 meters. The intervals of the medium branch groups on the main branches are 50 to 70 centimeters, and the intervals of the small branch groups are 10 to 20 centimeters. The tree shape has the advantages of simplicity and convenience in pruning, quickness in formation, earliness in fruiting, convenience in management, good ventilation and light transmission conditions and the like.

Description

technical field [0001] The invention relates to a tree shape and its shaping and pruning method, in particular to a pear tree shape with multiple main branches and its shaping and pruning method. Background technique [0002] The tree shape of fruit trees is an important part of fruit tree cultivation. The structure of the tree shape has a great influence on the difficulty of orchard management, the tree vigor of fruit trees, the control of diseases and insect pests, and the yield and quality of fruits. At present, the tree shapes used in the production of pear trees are mainly trunk sparse-layer shape, delayed open-heart shape, open-heart thin-layer shape, etc. [0003] (1) The main trunk is sparsely layered. The trunk height is 60-80 cm, with an obvious central trunk. The whole tree has 6-8 main branches, which are arranged on the central trunk in 3-4 layers; the first layer has 3-4 main branches. There are 2 main branches in the second layer of branches, 1 to 2 main bran...
