The first summer cuts were mainly buds, which took place during the leaf cluster (Shijiazhuang from the end of April to the beginning of May). Wipe the two buds, leaving a single bud, and wipe out the useless shoot buds near the mouth of the saw or near the trunk of the young tree.

The second summer cut took place during the rapid growth period of new shoots (Shijiazhuang in mid-to-late May). The pruning is very important. The first is to adjust the growth potential of the main and lateral branches and control the excessive growth. According to the need to pick up the heart, promote the second and third branches, to form more moderate and short fruit branches. The second is the pruning of the prosperous branches of the main and lateral branches that are growing vigorously, cutting the main shoots and leaving the auxiliary shoots to ease their growth. The third is to strengthen the back of the competition branches and Wangzhi pruning. If there is space, one or two secondary shoots may be left for the competitive or leggy fruit branches, and the culture will become the result of the shoots. If there are no shoots, it will be short at 30 centimeters to promote new shoots. It is worth noting that: The treatment of branch and Wangzhi is best handled in the early stage of vigorous growth, and the effect is better. In addition, Wangzhi is mainly the new shoots of latent buds in the canopy and the new shoots of the cut-out buds. Therefore, the new shoots of latent buds are sprouted. To get rid of from the base.

The third summer cut took place from late June to early July. The pruning is mainly to control the growth of Wangzhi, and the pruning branches are still properly pruned according to the principle of pruning. Since they have entered the late growth stage, the pruning should not be too heavy, and the tree standing upright varieties can be opened at an angle to the competition branches and leg chairs. On the basis of the last trimming, if the branches are still too dense, they can be removed. If there is space, one or two auxiliary tips can be left and the rest can be cut off.

The fourth summer cut took place from the end of July to the middle of August. The main reason is to remove the Wangzhi, which has not been controlled through three times of pruning, from the base. Two or three shoots of new growth can be removed from the base. Cut off the immature part of the long branch that has not stopped growing. Pull branches on small branches.
