Problems solved by technology

The growth vigor of different varieties is significantly different. Planting pollinated varieties in rows or between rows will bring inconvenience to field farming management and fruit harvesting. At the same time, the garden appearance is not neat; Pear trees tend to be strong at the top and weak at the bottom, resulting in weak growth of the lower branches, cross-pollination, often poor pollination and fertilization, resulting in unstable fruit setting, few results, small fruit, irregular fruit shape, and reduced fruit quality.

Embodiment 1

[0032] A kind of method that trunk-shaped pear tree high connection controls top dominance and improves fruit setting rate comprises the following steps:

[0033] (1) choose pear tree kind B and C to make scion, the scion pear tree kind B and C that choose are the pear tree kind that growth potential is weak, easily become axillary flower bud, easily form short fruit branch, kind excellent, pollen;

[0034] (2) select 1-year life in spring, the main pear tree kind A that height reaches more than 2.4m, on the position of the main trunk 2.2m of pear tree kind A, pear tree kind B and C are grafted every other;

[0035] (3) The pear tree variety B or pear tree variety C grafted in spring will germinate and produce 2-3 new shoots in the same year, and the new shoots at the top of variety B or variety C are 1 / 2 shorter than the top shoots of variety A. Axillary flower buds;

[0036] (4) In the second year, variety B and variety C at the top of the pear tree bloomed, and variety B a...

Abstract

The present invention relates to a kind of method that the high grafting of trunk-shaped pear tree controls top advantage and improves fruit setting rate, comprising the following steps: selecting pear tree varieties B and C as scions; selecting pear tree variety A for main planting in spring; The pear tree variety B and variety C are grafted on the trunk of the pear tree at intervals; the pear tree variety B or pear tree variety C grafted in spring will form axillary flower buds and top flower buds in the same year; in the second year, the variety B and variety C at the top of the pear tree will bloom. Variety B and cultivar C pollinate each other, and pollen from cultivar B and cultivar C pollinates cultivar A. The method of the invention improves the fruit setting rate of each variety of pear trees, and the fruit shape is correct and the quality is excellent. At the same time, the dominance of the top of the pear tree is controlled, and the tree body is balanced up and down to form a three-dimensional structure. The tree body grows neatly and uniformly, which is convenient for field farming management and lays a good foundation for the high yield and high quality of pear trees.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a method for high grafting of trunk-shaped pear trees to control top dominance and improve fruit setting rate. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae. It is a perennial deciduous fruit tree, tree, oval leaves, white flowers, juicy fruit, crispy meat, sweet and sour taste, rich in nutrition, 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. Pear trees have a relatively long lifespan, up to 100 years or more. [0003] Pears are cross-pollinated plants that require pollen from other varieties to produce fruit. The growth vigor of different varieties is significantly different. Planting pollinated varieties in rows or between rows will bring inconvenience to field fa...
