Large young cherry trees require early expansion of the crown to fill the space and improve overall photosynthesis efficiency. To enlarge the crown of large cherry, we must first increase the amount of growth. Through reasonable management of fertilizers and water, the saplings should be accelerated. The pruning is mainly short and open angles. First, winter short trim. Short pruning can promote the growth of new shoots, increase the proportion of long branches, reduce the proportion of short branches, and expand the canopy. Short cuts can be divided into light, medium, heavy and extremely heavy 4 ways. Cut 1/4-1/3 shoots called light and short cut, cut 1/2 of the short cut, cut 2/3 of the short cut. In comparison, the new shoots with medium and heavy short cuts grow most prosperously. The number of branches is generally 3-5, and the branches of different varieties and different parts are different. Second, open the branch angle. A reasonable opening angle can quickly enlarge the crown and increase the light of the inner canopy. At the same time, it can weaken the apical dominance of the branches, promote the development of the lower branchlets, and form flower buds and flowering results earlier. The methods for opening the angle include pulling branches, taking branches, binding branches, supporting branches and the like, preferably in the growing period, because the growing branches are relatively soft and easy to operate. At the same time, it must be carried out at the sapling stage. The big branches are hard and easy to split and cause fluids and other diseases.
