About the most important summer pruning of apricot trees

Summer pruning of apricot trees is an important part of year-round pruning. Reasonable summer pruning plays an important role in the rapid prototyping of young trees and increasing the yield of primary fruit trees in the coming year. When pruning young trees in summer, the overgrown branches, competitive branches and upper dorsal branches should be heavily truncated or thinned. The extended branches of the main side branch and the central stem should be excised in late June to stimulate the germination of secondary branches to increase the grade and number of branches and buds, which can not only make the crown of apricot trees form early, ease the growth of branches, but also reduce the ineffective growth of branches. The ventilation and light transmission conditions of young trees can be improved by removing too many and too dense branches. In the early fruit stage, apricot trees in summer pruning and early fruit stage are mainly thinning or heavy pruning, thinning or heavy truncation, including competitive branches, upper back branches, overgrown branches, reasonable thinning of overdense branches, improving ventilation and light transmission and preventing the growth of ineffective branches. Pruning and rejuvenating old apricot trees, summer pruning is very important. For example, the number of new shoots sprouting on the big branches retracted in winter is large and the growth potential is strong in the coming year, the upper branches and overgrown branches should be removed or truncated in summer shearing, so as to reduce the growth of useless branches and increase the rapid growth of retained branches. The thinning of over-dense branches can cut short the main growing points where the growth is exuberant, induce secondary branches and increase the amount of branches and buds. Summer shearing should be carried out many times from June to August. In order to keep the branches fully supplied with nutrition and remove the useless branches, the auxiliary shoots newly growing in spring should be cut in summer, which is generally carried out from June to August in our province.
