Select the pulling method for branch pulling, so that the trunk (branch) or big branch changes its original direction and orientation and grows continuously according to the predetermined orientation and trunk shape. Branching is usually used in pot experiments and various brewing buds, and the shape (dry shape) of the required seedlings is usually achieved by pulling, twisting, bending, bending and traction. Such as the emergence of seedlings such as Podocarpus and Ficus. 、。
In order to save nutrients and the demand for coins, the remaining shoots should be erased immediately to allow the remaining shoots to grow normally. Such as: butterfly fruit, face, basin frame, there are many buds on the branches, so we should erase the remaining buds in time.
Cut off a part of the branches by cutting them short. Usually, before thinning, you can choose short cutting, remove the strong branches of 1/3- 1/2, and then promote the high growth of the trunk. Such as: pot rack, Manglietia glauca, Hainan red bean, etc. 、
Thinning is called thinning when all branches are cut from the base of a branch or branch group. After thinning, the growth trend of the remaining branches is enhanced, the nutritional area is relatively expanded, and the ventilation and light transmission of the crown are improved, which is beneficial to its growth and development. Principle of leaving branches: it should be sparse but not dense, evenly spread and reasonably controlled. Attention should be paid to thinning and interspersed.
Branches, overlapping branches, upright branches, drooping branches, pest branches, closely spaced and crowded branches or branches. We should always remove those competitive branches that hinder the growth of the trunk. The growing point (terminal bud) of the branch. After removing the core, it can promote the growth of branches, and then achieve the intention of balancing the branch potential and controlling the growth of branches, and obtain the ideal crown shape of seedlings. Such as: butterfly fruit, almond _ head shape, ball crown, etc. Injured branches damage the bark, phloem and xylem of branches, so as to weaken the growth potential of branches and smooth the tree potential. Most of the damaged branches are carried out in the growing season, which has great influence on some parts and little influence on the growth of the whole tree.
Ring stripping. Stripping a certain width of bark from the right part of a branch or branch base with a knife can hinder the downward transportation of sugar at the top of the branch for a period of time, which is beneficial to the accumulation of nutrients and flower bud differentiation in the branches above girdling. Therefore, it inhibits the growth of T nutrients and promotes reproductive growth. Suitable for branches with few flowers and fruits at the peak of development.
