Embodiment 1

[0017] A kind of pruning method of pear tree, comprises summer pruning and winter fixed tip pruning, and summer pruning comprises the following steps:

[0018] Step 1, Topping: After planting, the pear tree should be topped when the treetop grows to 70cm in the first year, and the length of the pear tree should be removed to be 15cm. When the length is 60cm, pick the heart again and select the second backbone branch, and the length of removal is 15cm; in the second year, continue to cultivate 2 backbone branches on the central trunk; in the third year, pull up or hang all the backbone branches to make the base angle is 60°;

[0019] Step 2, ring cutting: when the pear tree is in full bloom, all the backbone branches are ring cut;

[0020] Step 3, take branches: take branches from the backbone branches after 1 month of circumcision;

[0021] Winter fixed-shoot pruning includes: pruning the whole tree every year from harvesting fruit to budding, removing all upright branches a...

Embodiment 2

[0023] A kind of pruning method of pear tree, comprises summer pruning and winter fixed tip pruning, and summer pruning comprises the following steps:

[0024] Step 1. Topping: After planting, the pear tree should be topped when the treetop grows to 75cm in the first year. The length of the pear tree should be removed to be 18cm. When the length is 63cm, pick the heart again and select the second backbone branch, and the removal length is 18cm; in the second year, continue to cultivate 3 backbone branches on the central trunk; in the third year, pull up or hang all the backbone branches to make the base angle is 65°;

[0025] Step 2, ring cutting: when the pear tree is in full bloom, all the backbone branches are ring cut;

[0026] Step 3, take branches: take branches from the backbone branches after 1.5 months of circumcision;

[0027] Winter fixed-shoot pruning includes: pruning the whole tree every year from harvesting fruit to budding, removing all upright branches and o...

Embodiment 3

[0029] A kind of pruning method of pear tree, comprises summer pruning and winter fixed tip pruning, and summer pruning comprises the following steps:

[0030] Step 1. Topping: After planting, the pear tree should be topped when the treetop grows to 80cm in the first year. The length of the pear tree should be removed to be 20cm. When the length is 65cm, pick the heart again and select the second backbone branch, and the removal length is 20cm; in the second year, continue to cultivate 3 backbone branches on the central trunk; in the third year, pull up or hang all the backbone branches to make the base angle is 70°;

[0031] Step 2, ring cutting: when the pear tree is in full bloom, all the backbone branches are ring cut;

[0032] Step 3, take branches: take branches from the backbone branches after 2 months of circumcision;

[0033] Winter fixed-shoot pruning includes: pruning the whole tree every year from harvesting fruit to budding, removing all upright branches and ove...

Abstract

The invention discloses a pear tree pruning method in the technical field of fruit tree planting. The pruning in summer comprises following steps: step one, pinching: when the treetop of a pear tree after field planting in the first year is 70-80 cm long, pinching and steam determination are performed, a first skeleton branch is reserved, and when a first bud at the top end of center stem of the pear tree is 60-65 cm long, the pinching is performed again and a second skeleton branch is reserved; 2-3 skeleton branches are cultivated on the center stem continuously in the next year; all the skeleton branches are pulled upwards or suspended downwards in the third year, and a basal angle is enabled to be 60-70 degrees; step two, girdling; step three, branch bending. The normal bud pruning in winter comprises steps as follows: the whole tree is subjected to fixed bud pruning before germination after fruits of the pear tree are harvested every year, all erection branches and overlapping branches on the skeleton branches are removed, one strong branch is taken as an extended branch of each skeleton branch, and watershoots are all pruned away from the bases. After the planted pear trees are pruned with the adoption of the scheme, ventilation and light transmission of crowns of the pear trees can be enhanced, and the yield of pear tree fruits is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a pruning method for pear trees. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous fruit tree, tree, oval leaves, white flowers, juicy fruit, crispy meat, sweet and sour taste, rich in nutrients, containing protein, fat, sugar, crude fiber, calcium, Minerals such as phosphorus and iron and multivitamins have the effects of lowering blood pressure and nourishing yin and clearing away heat. [0003] Pear tree is a tree species with dryness, strong polarity, obvious top dominance, high germination ability and low branching ability. During the planting process, the tree often appears strong at the top and weak at the bottom, strong at the front and weak at the back, many backbone branches, many branches, overlapping branches for shade, closed canopy, poor ventilation and light transmission, which le...
