1. Pruning of the central trunk: the height of the fixed trunk is about 60 ~ 80 cm, and the central trunk grows vertically. Leave 50 ~ 60 cm in front of the extension branches of the central trunk in the first winter; In the winter of 2003, the extension branches of the central trunk were cut off by 40 ~ 50 cm; The winters in the fourth and fifth years are basically formed, and the small main branches on the central trunk have been selected, so we can have a happy autumn. After falling, in order to maintain the crown height of 2 ~ 2.5 meters, weak branches can be used to change heads every year.

2. Cultivation of small main branches: 2 ~ 4 small main branches are selected to stay on the central trunk every year, and when the new branches stop growing, they are pulled out, generally becoming horizontal branches. In the four years after planting, the small main branches are generally not pruned in winter, and the extended branches of the small main branches are not shortened. For the small branches with a length of 1 m, it is necessary to support the horizontal pulling, and for the short-growing small branches, it is not pulled for the time being, and then it is pulled horizontally when it reaches a length of 1 m.. When the small main branch of 10 ~ 15 has been selected, the small main branch that is too long and too large should be retracted in time. The thickness of the small main branch should not exceed 1/2 of the thickness of the central trunk in this section. When the small main branch is too thick, some branches can be thinned on the small main branch to weaken its growth intensity. It is necessary to avoid the phenomenon that the upper part of the tree is strong and the lower part is weak. If you are strong and weak, you must restrain the strong and help the weak. The dense branches on the upper part of the central trunk or the strong branches on the upper small main branches can be properly removed, and small and medium-sized fruit branches can be equipped and cultivated on the small main branches.

3. Remove useless branches: timely remove the competitive branches on the central trunk and the upright branches, overgrown branches, dense branches and accumulated branches in the inner room, so as to ensure good ventilation and light transmission, and stabilize the output value and tree potential.

4. After the citrus seedlings of Red Beauty are planted, after 4-5 years of young tree shaping, they gradually turn into the formal fruiting period. At the beginning of the results, we should also pay attention to cultivating tree shape and continue to complete the plastic surgery task. However, the key point of pruning in the whole fruit-bearing period is to balance the growth and fruit and keep the tree vigorous.
