Problems solved by technology

At present, stone fruit trees in my country, such as peaches, plums, apricots, cherries, etc., are still mainly in the natural happy shape, and they are pruned during the winter dormant period. The tree is fixed, the output is limited, and fine pruning has certain requirements on the number of labor and skills

Embodiment 1

[0050] refer to figure 1 :

[0051] The growth period of the first year: the seedlings are planted in autumn or early spring, the row spacing of the seedlings is 1.5m, and then the position with full buds on the left and right sides is selected within 45cm from the ground; 6. Choose to keep one robust new shoot on each of the left and right sides, and erase the rest; then let the two branches grow upright until the length exceeds 2m, and then carry out continuous topping; after the branches stop growing in autumn, remove the The two large branches are horizontally fixed to the first baseline 1 by pulling the branches, and are distributed on the left and right sides of the main trunk 6 as the primary main branch 7;

[0052] The dormant period of the first year: the branches on the two first-level main branches 7 are selected and pruned, all the branches facing the ground are removed from the base, and the branches growing on both sides are kept if the thickness is less than 61...

Abstract

The invention relates to the technical field of fruit tree cultivation, in particular to a method for shaping and pruning plum trees and apricot trees. The present invention proposes a method for shaping and pruning plum trees and apricot trees. The first year of growth: the seedlings are planted in autumn or early spring, and the first-level main branches are cultivated; the first-year dormant period: the second-level main branches are cultivated; Second-year dormancy period: cultivate side branches; third-year growth period: side branches are finalized; third-year dormancy period: cultivate fruiting branches; first-level main branches, second-level main branches and weak branches that are too dense on side branches grow from the base Thinning, leaving 2 to 5 cm shorter than 1 / 2 of the thickness of the growing branches; the fourth growth period: Spray potassium dihydrogen phosphate and sugar alcohol boron once in June and July, and differentiate flower buds in summer, and bear fruit in the next year; Four-year dormant period: maintain the tree shape, remove excessively prosperous and dense branches that disturb the tree shape, and ensure that the thickness of the branches decreases step by step. This pruning method can make full use of the three-dimensional space, save land resources, and is easy to manage.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for shaping and pruning plum trees and apricot trees. Background technique [0002] The shaping and pruning of fruit trees is a very important and technical work in the process of fruit tree cultivation and management. It requires rational use of the characteristics of fruit tree branches and buds on the basis of not violating the growth and development laws of fruit trees. Through different treatments of branches, artificially intervene in the distribution, transportation, accumulation and consumption of fruit tree nutrients and hormones, and improve the relationship between fruit trees and the growth environment. , adjust the balance between vegetative growth and reproductive growth of fruit trees, and promote fruit trees to make full use of space, light energy, and materials to achieve high-yield and high-quality purposes. [0003] Looking back at the ...
