Pruning method of apricot tree
1, fruit expansion stage
In order to control the overgrowth of new shoots, the new shoots were pitted for many times, so as to improve the fruit setting rate and single fruit weight. Wipe off or twist off the new shoots that stand upright on the back to prevent the trees from growing on the trees and worsen the light inside the crown. After the fruit is harvested in the first half of May, retraction and thinning are combined to ensure the balance of tree growth and prevent compensatory overgrowth.
2. Young tree period
When pruning trees in winter, we should give consideration to both shaping and results. The main branches, lateral branches and extended branches should be lightly cut, and generally the full-length branches should be cut short by 2/3. The developing branches with moderate growth and relatively wide angle should be released slowly to promote the germination of short and medium branches and increase the number of fruiting branches, and the fruiting branches should be retracted in time after flowering or fruiting. Short and medium branches with large angles will become flowers more easily, so try not to trim them.
Young trees with weak growth potential should be pruned properly, too dense branches and too thin branches should be thinned, and more robust branches should be kept, and the upright vigorous branches should be leveled as auxiliary branches to promote the development of thick, medium and short fruit branches.
3. Full fruiting period
Appropriate pruning should be carried out according to the specific conditions of branches to maintain the stability of fruiting parts and growth. Retract the weak main branches, lateral branches and perennial auxiliary branches in the strong branches, so as to restore the growth momentum of the trees, update and rejuvenate the lower and inner branches of the crown in time, and let the fruit trees continuously produce new strong fruiting branches, which can achieve the purpose of increasing production.
