Three-main-branch peach tree shape and pruning method

Abstract

The invention discloses a three-main-branch peach tree shape and a pruning method. The tree shape has a height of 2.4-2.6m, a trunk height of 30-40cm, and three evenly distributed main branches located outside the south are left on the trunk. The angle between adjacent main branches is 110-130°, the angle between each main branch and the main trunk is 50-55°, and there is a permanent raising branch at the base of each main branch, and fruiting branches grow on each main branch. The tree forming time of the present invention is short, has the advantages of high light efficiency, premature, high yield, and stable yield. Because the fruit can receive sufficient light, the tree body is strong, the flower buds are full, the yield is stable, and the fruit quality is good; and because the main branch is small and oblique It grows at a high degree and the overall height is not high, so it is not only conducive to pruning and fruit picking by personnel standing on the ground, but also suitable for mechanical operation between rows; at the same time, its pruning method is simple, easy to master, and can be quickly promoted.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting and management, in particular to a three-main-branch peach tree shape and a pruning method. Background technique [0002] Peach tree is a light-loving tree species with strong germination rate and branching ability. The buds of peach trees are precocious, and in areas with long growing seasons and suitable environmental conditions, they can produce 3 to 4 secondary shoots (or even more times) within a year, forming multiple branches and multiple growths, giving Shaping pruning provides favorable conditions for accelerated fruit tree formation and early fruiting. [0003] At present, the high-yield peach tree shapes in practical application mainly include natural happy shape, trunk shape, Y shape and so on. Among them, the natural happy shape includes 3 main branches interlaced on the main trunk, which are firmly combined with the main trunk, have a large load capacity, and are not ea...

AI Technical Summary

Problems solved by technology

However, this tree shape generally takes 4 years to take shape, the early yield is low, and the 5-year-old tree can only stabilize the yield, and the tree shape pruning technology requires high technology, which is not easy for fruit farmers to master

The trunk shape has the advantages of simple structure, convenient management, ventilation and light, early fruiting, and quick results. Generally, it takes shape in the first year, and it can bear fruit or a high yield in the second year, but the quality of the fruit is relatively poor, and because the trunk is upright, it is easy to grow. Strong, so that the result part moves up, and requires higher pruning technology

The Y-shape requires wide rows and dense planting. Because of the ventilation and light transmission, the fruit is high-quality, the yield is quick, and it is convenient for mechanized management. However, the cultivation technology of the tree-shaped skeleton is relatively high. If it is not done properly, it is easy to split or the main pole ( branch) no sharpness, small bearing capacity, etc.
