Pak Lei in autumn is also called Pak Lei. The tree body is stout, the young branches are erect, the branches are flourishing, and it takes 4 ~ 5 years to blossom and bear fruit. As a result, branches gradually opened and the growth potential eased. Strong branching ability, 2 ~ 3 long branches can be made after long branches are cut short. Mainly bearing short fruit branches, some medium-long fruit branches and a small number of axillary flower buds. Short fruit branches have long life and are easy to flourish when stimulated. Most fruit forests can germinate 1 ~ 2 branches, but it is difficult to blossom and bear fruit continuously in that year, and few short fruit branches are formed. The regeneration ability of buds and branches at the base of branches is weak, and the resulting parts move out quickly. It is easy to have "big and small years" in the full fruit stage, and the old and weak branches are mainly regenerated by auxiliary buds on the side of the base.

Generally speaking, trimming can be carried out according to the cutting method of the Pak Lei system described above. Young trees should pay attention to the opening angle of main branches and adopt measures to promote flowering and fruiting. Therefore, big trees should pay attention to retracting long branches, reviving weak branches and renewing old branches. Especially the weak branches after aging, we should use auxiliary buds to update them in time. In the lower and inner part of the crown, we should cultivate some large and medium-sized branches with many branches but relatively compact, and pay attention to improving their ventilation and light transmission conditions to control the outward migration and annual occurrence of fruiting parts as much as possible.
