Peach trees with three main stems have the characteristics of firm frame, good ventilation and light transmission, high yield and convenient picking management, but the early yield is low, and they are often selected under the plant spacing of 3m× 4m, 3m× 5m and 4m× 5m. The dry height is generally 30? 60 cm, if the transplanted seedlings are finished products, 50 cm off the ground before budding in spring. Cut at 60 cm saturated bud, cut 15? 20 cm is a plastic belt.

Wipe off all the buds under the plastic belt after sprouting. Pay attention here. In some areas, pests are more harmful in spring. Put the plastic belt on the net bag. When the tip is about 30 cm long, choose a balanced growth potential and an appropriate orientation. It is best not to leave the north-south branch. Three branches randomly arranged from left to right will be cultivated as future main stems. If other branches flourish and compete with the main stem for nutrition, they need to be dispersed by methods. Those with weak growth potential can be carried out. After close planting control, fruiting branches can be produced in the same year, leading to early fruiting.

If the transplanted peach seedlings are semi-finished seedlings, it is easier to cultivate the main stems. When the fruit tree seedlings grow to 60? When 70 cm picks the top, you can usually take out 5? Eight secondary buds, then three satisfactory main buds are selected as main buds for cultivation, and the remaining tender buds are thinned or reserved 1? Two weak branches serve as auxiliary branches.

When cutting in winter in the first year, the confirmed main stem should be cut short, and the cutting length should be determined according to the growth level, size and bud saturation of branches, generally 80? 100 cm, the cutting buds should be saturated and pay attention to orientation. When the angle of view of the main pole is small, leave buds, and when the orientation is skewed, leave lateral buds to adjust, or adjust the angle of view and orientation of the main pole through bracing.

Usually the angle of view of the main pole is 40? 45 degrees, the viewing angle is too large, the future carrying capacity is small, the fruit is too close to the ground or touches the ground, which interferes with the quality and is inconvenient for farming, fertilization and spraying. The angle of view is too small, the trees are lush, and the ventilation and light transmission in the inner chamber are poor, which is easy to cause the grafting side to be empty and the epiphysis yield is low, so the angle of view of the main pole is usually maintained at 40? 45 degrees. In the second year, increase the head of the main pole, cut off a third of the total length, and choose side branches.
