A method for constructing the high-yield tree shape of central leading branches of citrus fruit trees

Abstract

The invention discloses a method for constructing a high-yield tree shape of central leading branches of citrus fruit trees, including a method for constructing a tree shape of a juvenile tree and a method for constructing a tree shape of an adult tree. The adult tree of the year adopts the method of artificial intervention; the construction method of the tree form of the juvenile tree is to guide the growth of the branches of the juvenile tree. Through directional cultivation of central guide branches, artificially manufacture main trunk branches, upright branches or central branches, increase the thickness of fruiting branches, cultivate more powerful branches, enhance the bearing capacity of fruiting branches, and increase their ability to bear force. Supports can be reduced. In the past, some tree-shaped structures often paid too much attention to the purpose of the economic characteristics of the results. Some fruit trees have slender fruiting branches and rely on external force support in the later stage of fruiting.

Description

technical field

[0001] The invention relates to a method for constructing a high-yield tree shape, in particular to a method for constructing a high-yield tree shape of central guide branches of citrus fruit trees. Background technique

[0002] The stem is the skeleton of the plant body, and the main stem and branches at all levels are important organs to support leaves, flowers and fruits, so that they are reasonably distributed in space. The reasonable distribution of plant organs in space is an important factor for fruit trees to obtain maximum photosynthesis and transpiration, store more energy substances, and reduce the occurrence of pests and diseases. In the process of fruit tree growth, seeded fruit trees generally have a strong apical dominance, but the apical dominance of fruit trees propagated by grafting is not obvious or has no apical dominance, but apical dominance exists. Apex dominance refers to the phenomenon that the top buds of the main stem do not inhibi...
