Peach Pruning
Peach is dominated by dormant season trimming, supplemented by pruning in the growing season. Dormant season pruning should be after the cold, spring sap flow is appropriate before, mainly to cultivate the skeleton and flower branch groups, so that branches are substantial, and at the same time to cut off the tree shape, affect the appearance of the branches.
Peach trimming
The different growth stages of pruned with different ages have different growth characteristics at different ages. In order to make the pruning scientific and reasonable, the pruning characteristics of each age stage are divided.
(1) Early stage of viewing (4 to 6 years). From the grafted survival to the main branch and first-order lateral branch formation, this period has adequate nutrition, strong growth, easy to send branches, branching angle is small. Due to the dry and weak nature of the peaches, it is also a characteristic of strong positive tree species. It should be done in the winter to select and retain the main branch. At the same time, topping or panning should be done in the summer to eliminate the dense branches and increase the branches and grades to make it a perfect tree shape in the short term.
(2) Best viewing period (6-25 years). From the basic formation of the canopy to the beginning of aging of the tree, this period the crown is gradually expanding, strong growth, flowering lush, urgent requirements for soil, fertilizer, water, but pay attention to the renewal of the branch to prevent aging.
Peach Pruning Method
1. First determine the backbone of the tree branches. The blue peaches generally have 3 to 5 main branches. The affiliation relationships between the main branches and the lateral branches at each level are clearly defined. The branches of the main branches are found and balanced according to the growth potential of the main branches. The short cuts are mainly used to restrain the strong branches. The weak method balances the branches. When the main branch extends too long, it must be retracted in a timely manner. Select the appropriate branch to replace the original branch for short cutting. The main branch must be higher than the other branch, and stay longer.
2. Second remove unused branches. To eliminate cross-branches, overlapping branches, diseased branches, injured branches, thin branches, and unnecessary leg-length branches. Then trim the branches. If we only pay attention to the arrangement of the backbone branches during pruning and pay no attention to the cultivation of the flowering branch groups, the phenomenon that the flowering parts will move upwards, the internal litchi will die and the flowering will be planarized will occur soon. Flowering branches can be divided into large, medium and small according to their branches and grades. The branch is generally above the 4th branch and is equipped with the dorsal and oblique sides of the middle and lower part of the canopy and the main branch.
3. Finally trim the flower branch. Long squid stays, and long-medium-sized long branches have the best flowering. 8 to 12 flower buds should be kept short, middle squid to stay 5 to 6 buds, short squid branches to 3 to 4 buds, clipping buds to leave leaf buds, and bouquet-like branches to be absent. Short cuts.
Blue peach is a strong positive tree species, sensitive to light photography, the same pruning under different lighting conditions, branches reflect different situations. Should be planted in front of the building, due to the large differences between the northern and southern light, resulting in different growth conditions of the branches. At the time of pruning, the south should be properly thinned, and the angle should be opened in order to penetrate the sunlight and ease the branching. Due to lack of illumination in the north, the branches are numerous and weak, so the short-cut should be at the bud, and less sparsely to promote the branch.
