The Y-shaped shape is an open-shaped shape with two main branches that was researched and developed in my country in the 1980s. The main trunk is relatively short, and the whole tree has only two main branches, extending between the rows. Each main branch is equipped with 2 to 3 side branches, and the main branches and side branches are equipped with growing branches and fruiting branches. The two main branches grow at random, with an angle of about 45°, resembling a Y-shape. This tree shape is generally planted in wide rows and densely planted, and the crown can be large or small, suitable for different planting densities. This method can be used to shape row spacing from 2 to 6 meters and plant spacing from 0.8 to 3 meters. Generally, when the plant spacing is less than 2 meters, there is no need to equip lateral branches, and the fruiting branch groups are directly attached to the main branches; when the plant spacing is greater than 2 meters, each main branch can be equipped with 2 to 3 lateral branches. The high-density, high-quality and high-yielding cultivation technology of peach trees invented by Jia Kegong and others has a spacing of 0.8 meters × 2.5 meters between rows. Each tree has two large branch groups directly from the trunk. Under general management conditions, every 667 meters in the second year of planting 2 The highest yield of high-quality fresh fruit is 50 tons/ha, and 4-year-old fruit can reach 90 tons/ha.
