Method for controlling top edge of trunk pear tree to improve fruit setting rate by high grafting

Abstract

The invention relates to a method for controlling the top edge of a trunk pear tree to improve the fruit setting rate by high grafting. The method includes the following steps: selecting pear tree varieties B and C as scions; selecting a main pear tree variety A in spring, and grafting pear tree variety B and variety C on the trunk of pear tree variety A through separate plants; forming axillary flower buds and top flower buds in the same year through the grafted pear tree variety B or pear tree variety C in spring; in the following year, blossoming, by variety B and variety C at the top end of pear tree, and pollinating with each other; and meanwhile, pollinating, by varieties B and C, variety A. The method improves the fruit setting rate of each variety of pear trees, has positive fruitshape and excellent quality, simultaneously controls the top edge of the pear trees, and the tree body is balanced up and down to form a three-dimensional structure. The tree grows neatly and uniformly, which is convenient for agricultural management in the field and lays a good foundation for high yield and 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...

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.
