① During crown shaping, it is necessary to prevent the "bare legs" in the middle and lower parts of the main branches from not branching. Therefore, the extension head should not be too long, and should generally be cut off within 40 cm of the whole bud below the middle. The spacing of the first floor of the lower part of the central trunk should be cut off within two years to increase interlayer branches and cultivate auxiliary branches. In the culture of basal main branches, strong seedlings can be adjacent and fine seedlings can be adjacent. When the center is strong, it can be bent and extended by changing the competitive branches to prevent the top from being strong and the bottom from being weak.

(2) Young trees can be pruned by pruning again and pruning in spring to improve the germination rate, prevent the phenomenon of "bare legs" in the middle and lower parts of branches, and pay attention to the opening angle of branches. Results Branches can be cultivated by putting branches first and then shrinking branches, cutting first and then putting branches, and continuous short cutting, so that branches of various types and sizes appear in the crown. Try not to slow down and lightly cut long branches, but cut them in the middle and lower parts. The strong branches of "bare legs" are carved and peeled by many people. At the same time, pay attention to thinning the competitive branches and strong branches on the back to promote the germination of lower buds into branches. With the uniaxial extension of the whipstock, branches and fruiting branches can be cultivated by wearing a hat.

③ Fruit trees should pay more attention to cutting, shrinking and thinning flowers and fruits. In particular, the "three-three system" pruning technology of "one third of the results, one third of the slow release and one third of the short cut" is adopted to prevent "big and small years". Most branches of Guoguang tree respond well to short cutting, especially the overweight cutting on the base pile platform is easy to produce medium and short branches. Even if the strong branches are thinned, a few withered buds are left at the base and combined with direct cutting, strong cutting and weak cutting in the second year, good results can be achieved. Therefore, "wearing a hat" is used more. Bud branches with large top leaves and long cones on the back can promote flowering and fruiting by breaking the top. For a single bunch of flowers that have been left for many years, you can "wear a hat" or let the flowers retract and let them bear fruit as much as possible. The fruit setting rate of Guoguang inflorescence is very high. In addition to controlling the amount of flower buds in winter, fruit thinning is also needed in summer. Fruit thinning can be maintained according to the number of auxiliary tips of the fruit table, and each auxiliary tip can leave one fruit. Old trees should pay attention to the treatment of drooping horizontal branches and dense branches around them to improve the light in the crown. And leave flowers and few fruits, and take turns to update the over-age fruiting branches. For the old and weak fruiting branches, when there are branches at the lower part, they can be retracted at the branches, and when there are no branches at the lower part, they can be retracted at the base or on the better fruiting table at the lower part.
