What is the natural happy structure of fruit trees?

A naturally happy shape is a tree with no central trunk and only one layer of three main branches at the base. The trunk is low, generally 3 ~ 5 cm. The main branches are mostly arranged in adjacent forms on the trunk. The lateral branch culture has the same sparse layer shape. The height of the tree is generally 2. ~ 2.5 meters, and the crown diameter depends on the row spacing. The extension direction of the main branches between adjacent plants is best to be staggered, and the head can not grow.

this shape is characterized by good ventilation and light transmission, which is beneficial to improve fruit coloring and quality, and the crown management is more convenient. At present, it is mainly used for peach trees and other fruit trees with strong photophobia. When it is used in apples and pears, it is difficult to improve the yield of trees due to the lack of main branches and too flat crown, which is not conducive to three-dimensional fruit < P > Natural happy tree structure.
