Tree shape and pruning method of three-main branch peach tree

Abstract

The invention discloses a tree shape and pruning method of a three-main branch peach tree. The tree is 2.4-2.6m high and the trunk is 30-40cm high; three uniformly distributed main branches are left in the trunk outside the south; the angle between the adjacent main branches is 110-130 degrees, and the angle between each main branch and the trunk is 50-55 degrees; the base of each main branch is respectively provided with a permanent branch, and each main branch is provided with a bearing branch. The tree shape of the invention has the advantages of short forming time, high light efficiency, premature delivery, high yield and stable yield. Due to the sufficient illumination of fruits, the tree body is robust, the flower bud is full, the yield is stable and the fruit quality is good. Sincethe main branches grow with small inclination and the overall height is not high, people is convenient to stand on the ground to perform pruning and fruit picking, and inter-row mechanical operation can also be achieved. Meanwhile, the pruning method is simple to operate, easy to master, and can be quickly popularized.

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.
