During the year, fruit trees should be grown in the late summer and early autumn (mid-August to mid-September). In this period, the branches are soft and plastic, and can be adjusted according to the requirements of the tree, open the angle of the branches, or change the direction of the extension of the branches; can improve the conditions of the fruit trees get light, increase the photosynthetic synthesis of nutrients, and accumulate more Nutrition; can control the growth of new shoots, so that the shoots in the middle and lower parts of the growth and enrichment, the following spring, the growth of shoots are more balanced, increase the number of short branches, can form a short fruit tree group, slow promotion of flower effect is better.
Young apple tree pull open angle
Branches have strong growth apical dominance, and shoots grow upright. For trees between 4 and 5 years old, the main pedestal angle must be opened. The base angle should be opened to 60-70 degrees; the tree should be opened 6-7 years ago to open the main branch. The main angle is that the waist angle should be opened to 70-80 degrees; the main branch angle should be opened to about 60 degrees.
Left side branches of the tree, open the main branch angle, but also pay attention to open side branch angle, side branch opening angle is greater than the main branch angle, side branch length is lower than the main branch.
For auxiliary branches, competitive branches, prosperous branches and leggy branches, methods such as twisting tips, picking hearts, and other branches can be used to control their growth and promote flowering.
Pulling branches and opening angles will lead to barrows, causing confusion of trees, and affecting the results of saplings and early high yields.
1. Branches growing more prosperous, severe bald phenomenon, should remove the strips, take measures to promote bare sections on the shoots, germination and branching.
2. Remove spurious sticks that cannot be used and improve lighting.
3. There are strips of growth and development space that can be utilized, which can be levelled to transform them into fruiting branches. Without prejudice to the air circulation and light transmission of the crown, it is possible to carry out long-range placements and use of branches, Take measures such as topping, twisting, girdling, circumcision, etc., to promote their sprouting, or to further cultivate the resulting sticks, promote their flowering results, retract them after the results, or when they need to be removed. Sparse.
Pull open angle notes
The tying rope should be suitable. Do not pull the twig into a bow. For the upper and lower branches of the canopy, pull the twigs so that the plants grow well.
