3+1 tree form of pear tree and shaping method thereof

Abstract

The invention relates to a 3+1 tree form of a pear tree and a shaping method thereof, belonging to the fields of pomology and fruit tree ecology. The tree form only has three main branches and a central trunk so as to be named as the 3+1 tree form. The tree form is small at the top and big at the bottom, thus branches on the upper part have small influences on the lower part, and the ventilation and light transmission conditions are good. Compared with a traditional small-crown sparse-layer pear tree form, the crown layer opening of the 3+1 tree form is improved by 14-18 percent; the fruit shape is big, and the quality is good; the content of a soluble solid state material in a fruit is improved by 0.8-1.2 percent compared with that in a small-crown sparse-layer fruit, and the high-quality fruit rate is higher than 90 percent; and the quality of fruits is good. The tree form has short and small crown and easy shaping, and the skeleton branch is directly connected with the branches, thus the tree form is convenient to manage and particularly suitable for Chinese pear varieties such as hosui pears, green-crown pears, yellow flower pears, Yuanhuang pears, Shingo pears, golden pears, and the like. The tree form is an ideal tree form for pear tree cultivation and has the characteristics of simplicity, convenience and easy application.

Description

technical field [0001] The invention relates to a pear tree 3 plus 1 novel tree shape and a shaping method thereof, and belongs to the fields of fruit tree cultivation and fruit tree ecology. Background technique [0002] Tree shape is the basis of pear tree cultivation. The traditional tree shape of pear trees in my country mainly includes evacuation and stratification. The tree shape is composed of a trunk and 6 to 8 main branches, which are divided into three layers. , poor ventilation and light transmission, severe pests and diseases, and uneven fruit quality. In order to improve the lighting conditions of pear trees, many pear producing areas in my country have improved the evacuated layered shape, adopting a small crown layered shape with 5 to 7 main branches. Compared with the layered shape, the fruit quality has been significantly improved. However, production practice has found that the layer spacing of this tree shape is small, the light is poor after the full fr...

Problems solved by technology

[0004]For this reason, the study not only has the advantages of foreign pear tree shape, ventilation and light transmission, good quality, but also overcomes the disadvantages of high production and management costs; The high-efficiency pear tree shape, which has the advantages of high yield and can overcome the shortcomings of poor light, poor quality, and difficult shaping, is the basic requirement for high-quality and efficient production of pears. The popularization and application of this tree shape is of great importance to the development of the pear industry. significance
