Hawthorn winter shears
Hawthorn winter pruning can promote the strong tree in the coming year, ensure the skeleton is firm, the branches are combined, the fruit is more excellent, the product is stable and longevity, and the purpose of premature birth, high yield, high quality and low consumption is achieved. It can be trimmed from November to January next year.
First, young tree pruning
1. Branches that grow obliquely or horizontally, if the growth is weaker than the main branch, the space allows growth to be retained. If the growth is strong, the methods such as circle branching, bracing, and controlling branches can be used to weaken the growth.
2. The auxiliary branches that are crossed, dense and hinder the growth of the skeleton should be removed according to the specific circumstances, so as to leave room for ventilation and light and give way to the backbone.
3, erect branches, competition branches are generally to be removed, such as fewer branches, optional growth is not strong, leaving 1/3 from the cut, and when the new shoots grow to 25 cm in May and June, many times, picking the heart, promoting branching .
4. More than three strong branches at the top of the extension branch of Wangshu. When pruning, the apex should be removed, the second branch should be weakened by the large cut, and the third branch should be used to extend the branch and make the main branch forward. To achieve the purpose of suppression before and after promotion.
5. The weak inner lychee should be removed, and the inner lychee without flower buds should be re-cut to make the branches compact.
Second, mature tree pruning
1. Retraction: For the auxiliary branches that are delayed due to slow release, they must be retracted and rejuvenated. When there is no result of the mother branch in the weak branch of the root branch, the branch should be retracted; for the extension of the single-strength growth, the branch should be retracted to promote the new branch.
2, sparse branches: timely removal of weak branches in the lower part of the base branch without flower buds; weakening and remaining strong for the peripheral results of many years of continuous and unable to form the mother branches, and thinning the weak branches of the inner scorpion and overlapping, overlapping auxiliary branch.
