Problems solved by technology

[0003] Compared with the oriental pears traditionally cultivated in my country, western pears have strong growth vigor, low branching ability, low germination rate, difficult flowering, and late results. The above characteristics have caused difficult management, high production costs and low economic benefits.
However, my country's traditional pruning method of sparsely planting large crowns, dispersing and layering the three main branches, emphasizing winter pruning and light summer pruning can no longer meet the needs of pear production, especially when labor costs are getting higher and higher. According to the growth and fruiting habits of pears, it is necessary to develop labor-saving pruning techniques for early fruiting to meet the needs of pear production in my country

Embodiment 1

[0028] A method for pruning pruning of Western pears with labor-saving and early fruiting, comprising the following steps:

[0029] (1) Pruning of young trees:

[0030] 1) In the spring after planting, cut the stem from a distance of 65 to 80 cm from the ground, so that there are 1 to 2 full buds under the cut, and wipe the excess buds;

[0031] 2) Before germination in the spring of the second year, all the buds within 1 m above the original distance from the central trunk should be carved. Use a small hacksaw to saw the top of the buds and 0.3 cm from the tip of the teeth, to a depth of 0.3 cm. Xylem; in late August of the second year, use a thin rope to flatten the branches with a length of more than 50 cm, that is, the angle between the branches and the central trunk is 90°C;

[0032] 3) In the spring of the third year, repeat the bud carving on the central trunk at the position where the buds were carved in the previous year, and wipe off the elongated branches that grew...

Embodiment 2

[0038] A method for pruning pruning of Western pears with labor-saving and early fruiting, comprising the following steps:

[0039] (1) Pruning of young trees:

[0040] 1) In the spring after planting, cut the stem from a distance of 80 cm from the ground, so that there are 2 full buds under the cut, and wipe the excess buds;

[0041] 2) Before germination in the second spring, all the buds within 1.2 m above the original distance from the central trunk should be carved. Use a small hacksaw to saw the top of the buds, 0.5 cm from the tip of the teeth, to a depth of 0.5 cm. Xylem; in late August of the second year, use a thin rope to flatten the branches with a length of more than 50 cm, that is, the angle between the branches and the central trunk is 90°C;

[0042] 3) In the spring of the third year, repeat the bud carving on the central trunk at the position where the buds were carved in the previous year, and wipe off the elongated branches that grew on the back of the flat...

Abstract

The invention belongs to the technical field of fruit tree pruning and particularly discloses a European pear tree labor-saving early-fruiting pruning method. In combination with actual production, by adopting a slender columnar European pear tree shape and by using techniques of bud carving, branch bending, bud picking, trunk cutting and the like, a labor-saving early-fruiting pruning technique which has the advantages that European pear trees can fruit from the third year and can yield highly from the fifth year after the European pear trees are planted, the European pear trees are not pruned basically in the first four years, the pruning quantity at a full bearing period is very small and 3-5 mu of European pear trees can be pruned per person per day. Not only can the labor force and the production cost be greatly saved, but also the cultivation goals of early fruiting and high efficiency are realized and the economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of fruit tree shaping and pruning, and in particular relates to a labor-saving shaping and pruning method for early fruiting of pears. Background technique [0002] Western pear is one of the two major cultivated pears in the world. The fruit is famous for its rich vitamin C, delicious taste and high quality. In recent years, with the introduction of various pear varieties, such as Hongxing, Cosia, Zaohong Comis and Hong Anjiu, there has been an upsurge in cultivating pears. In 2009, the national pear cultivation area was 100,000 mu, with a total output of about 100,000 tons. [0003] Compared with the oriental pears traditionally cultivated in my country, Western pears have stronger growth vigor, lower branching ability, lower germination rate, less flower formation, and late results. The above characteristics have caused difficult management, high production costs and low economic benefits. However, my c...
