Method for culturing tree forms of peach trees

Abstract

The invention relates to a method for culturing tree forms of peach trees. The method comprises the following steps of: selecting seedling peach trees as root stocks, wherein the seedling peach trees are good in growing conditions, developed in root systems, free from diseases and insect pests, 2-3 years old, and over 5 cm in the length of breast diameters; selecting adult peach tree plants which are strong in development and free from quarantine diseases and insect pests as scion-seed trees; separately cutting the smooth bark of the root stocks to form a horizontal streak and a vertical streak so as to form a T shape; horizontally cutting the bark 2-3 mm under a bud, then 1-1.5 cm above the bud, cutting into the root stocks with the knife to upwards push and cut to a horizontal knife edge under the bud, taking down a bud piece, unclenching cortex of a notch of the root stock, gently inserting the inverted bud xyloid bud piece which is cut well into the T-shaped notch, tightly binding up the T-shaped notch and the inverted bud xyloid bud piece with a plastic strip which is 2-3 cm in width, and leaving the bud and a leafstalk outside; after bud grafting, erecting a rain awning for blocking rain and directly irradiated sunshine; after buds are germinated, gradually removing the rain awning; after about 15 days when grafting is successful, cutting off the root stocks over interfaces; and after entering a growth period, respectively trimming survived branches every month, beginning to trim the branches on upper layers first, and then trimming the branches downwards.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for cultivating peach tree shape. Background technique [0002] Peach tree is an important economic forest fruit tree species in my country. It is widely cultivated in temperate and subtropical regions of China. In order to improve the economic benefits of peach tree cultivation, people have gradually practiced and summarized a variety of pruning methods. At present, the commonly used tree shapes of peach trees include: natural happy shape with two main branches without trunk, natural happy shape with three main branches, cup shape with multiple main branches, etc.; cylindrical or spindle shape with main trunk, etc. [0003] In the process of actual production, the inventor found that the existing technology has at least the following deficiencies: in the above plastic pruning practice, it is generally difficult to grasp the position of the main side branc...

Problems solved by technology

[0003] In the process of actual production, the inventor found that the prior art has at least the following deficiencies: in the above plastic pruning practices, it is generally difficult to grasp the position of the main side branches, the opening angle of the branch tips, etc., and it is prone to large deviations, resulting in difficulty in tree shape advantages. Fully exerted, the problem of sun shading occurs, and the fruit quality and yield are affected
