Peach tree pruning method

Abstract

The invention belongs to the technical field of fruit tree pruning, in particular to a method for pruning peach trees. Pruning in the first year: After the seedlings are planted, select full buds to fix the stem, and remove all branches on the main trunk at the same time; in summer, perform bud removal and branch thinning treatment, and remove competing branches, upright branches, over-dense branches, and flat oblique branches in winter. Keep fruiting branches for each peach tree; pruning in the second year: in summer, extend the center trunk and pinch or drop the head, keep the center trunk in winter, remove the branches at the base of the center trunk, and keep only the middle and upper fruiting branches; pruning in the third year: summer When pruning, keep the twigs, and keep the distance between each twig to bear fruit; in winter, remove the prosperous branches on the central trunk from the base, and let them bear fruit after flowering. The invention is scientific and reasonable, simple and easy to implement, and the peach trees are well ventilated and light-transmitting, easy to manage, high in yield and high in quality, high in peach quality, less damaged by wind and rain, less secondary peaches, and high in yield.

Description

technical field [0001] The invention belongs to the technical field of fruit tree pruning, in particular to a method for pruning peach trees. Background technique [0002] Peach trees grow faster and can bloom and bear fruit in the second year after planting. The treetops grow vigorously, and new shoots can be produced 3 times a year, and the second shoots can also form flowers, bloom and bear fruit. It can enter the full fruit period in 4-5 years. Due to the early results, the full fruit period can last for 10-15 years, and the life span of the tree is relatively short, generally around 20 years. The flower buds of peach trees are pure flower buds, and only one flower blooms in a flower bud. Some are single flower buds, some are compound flower buds. Single flower buds are born on short fruit branches and bouquet-shaped fruit branches, and compound flower buds are generally born on long fruit branches and mesofruit branches with better nutritional conditions.

Problems solved by technology

The conventional happy-shaped tree shape has low yield and slow forming in the early stage. From the full fruit stage, due to the large amount of nutrients flowing to the top of the tree crown and fruits, the base of the tree body cannot be supported by leaves for a long time, the aging of the trunk is accelerated, the glue flow is serious, and the life span is severely shortened. In the later stage, the base of the main branch is bare, the inner chamber is empty, and it is exposed to the sun for a long time, and the dry rot and rot are serious.

And because the height of the tree body is not enough, the three-dimensional space is not utilized enough, the quality and yield of peach fruit are low; the trunk shapes such as natural spindle shape and improved spindle shape can produce early results and increase fruit yield, but their branches and leaves are dense, and the ventilation and light transmission are poor. result in a decline in fruit quality;

[0004] Under the current planting and pruning mode, after several years of growth, the branches of peach trees basically cover all the space in the peach orchard. In summer, there is no ventilation and it is not convenient to work, which is easy to breed diseases and increase management costs.
