It consists of developmental branches, overgrowth bearing branches, overgrowth bearing branches and so on. After several years of cutting to promote growth, fruiting branches with different lengths were produced (Figure 6 1).

Fig. 6 1 culture process of fruiting branch

1 big fruit branches. Planted on the main branch, inclined back, staggered with the side branch, does not affect the side branch. Generally, robust branches are selected, and 5 ~ 10 short section (20cm) is left to promote germination and branching. Prune the vigorous branches at the front end in the winter of the next year, leaving 2 ~ 3 short nodes, becoming a medium-sized branch group in the third year and a large fruiting branch group in the fourth year.

② Medium-sized fruiting branches. Distributed on the back or both sides of the main branch, straight or oblique. Medium-sized fruiting branches are similar to large-sized fruiting branches in culture. When cutting in winter, the long branches (leave 15 ~ 20cm) or developing branches (20cm) can be cut short, and the vigorous branches in front can be cut off in the next winter, and the medium branches can be cultivated in the third year.

3 small fruit branches. Distributed in large and medium-sized fruit branches and main lateral branches, supplementing the gap between large and medium-sized branches. Generally, 3-5 segments of robust development branches or fruit branches are reserved, and 2-4 robust fruiting branches are born, thus forming a small fruiting branch group.

Results The shape of the branch group is conical, with good light transmittance, and the position of the branch group moves slowly, resulting in three-dimensional results.

The arrangement of fruit branches should be staggered in size, with large fruit branches mainly arranged on the back of backbone branches and inclined to both sides, and large fruit branches can also be arranged behind backbone branches. Medium-sized fruiting branches are mainly arranged on both sides of the main branches, or between the big branches, some of which are preserved for a long time, and some of which shrink or even become thinner year by year due to the development and expansion of adjacent branches. Small fruit branches can be arranged behind the main branches, on the back and on the periphery of the crown, which are kept when they are free and sparse when they are not free. From the whole canopy, the upward sloping branches are the main ones, supplemented by vertical and horizontal branches; Downward branches should always pay attention to improving branch angles, shrinking branches, pruning, renewing and rejuvenating. Results The arrangement of branches should be sparse on the crown, dense under the crown, large, medium and small alternately, with different heights and gaps. The height of the space occupied by the branches planted at the top of the crown should not exceed the branches of its main branches, which is beneficial to ventilation and light transmission and keeps the growth potential of the main branches (Figure 62).
