First, take heart. Its purpose is to control the growth of shoots, increase the number of branches and branches, promote branch transformation, and expand the canopy. This measure is mainly used on saplings and Wang tree. Picking time is better with the rapid growth of new shoots. When the new shoots are about 20 to 25 centimeters long, the tip of the shoot can be removed. If tree vigor is strong, the secondary shoots are still very prosperous after topping and can also be picked up twice or three times. Appropriate topping is an effective measure to promote early results and early high yield of cherry young trees. Second, pull the sticks. The purpose of pulling branches is to adjust the angle of the branches or auxiliary branches, to ease the tree potential and promote early results. Pull branches are carried out after the spring or after fruit harvesting in June. After a season of growing season is basically fixed and then pull the rope. When pulling branches, care should be taken to prevent large branches from splitting, and to prevent the branches from being pulled too high, and the central part of the branches that are pulled upwards to arch upwards, resulting in a small waist angle or a phenomenon of strips. Third, after fruiting branches and retraction. After the cherries are harvested, pruning is performed in order to adjust the structure of the tree and improve the ventilation and light transmission in the crown. The pruning method is mainly the thinning and retraction. Large branches with strong influence on ventilation, light transmission, and no reservation value in the crown can be removed from the base; Large branches with limited ability to affect only the local lighting of the crown but with a certain degree of result can be grown at large angles of branching. Shrinkage at the larger branches, specific treatment of the lower branch of the multi-purpose shrunk, senior branches of the branch can be feasible. In addition, when the shoots are not lignified from late May to early June, the shoots on the back erect branches, competition branches, and inward standing branches will be used to facilitate the formation of flower buds, which will lay a good foundation for high-quality and high-yield production next year.
