The main purpose of early plastic surgery is to enlarge the crown, increase the number of branches, and form a tree structure that can bear a certain yield, laying the foundation for future results; Pruning is to adjust the relationship between growth and fruiting, and to cultivate strong enough fruiting mother branches by pruning every year to lay the foundation for fruiting.
1, strong branches and strong buds bear fruit.
The difference between hazelnut and other fruit trees is that most flower buds are formed on long branches. The stronger the tree, the more flower buds there are. Therefore, the purpose of hazelnut pruning is to cultivate enough branches every year.
2. Advantages of basal branching.
Natural hazelnut trees tend to be shrub-like, mainly because the basic branches and lower branches have strong growth ability, which leads to the weakness of the top. Therefore, when pruning, we should pay attention to improving the angle and thinning the branches to avoid inhibiting the former and promoting the latter.
3, hazelnut sap flows early.
Because the sap flow period of hazelnut tree is early, the pruning period should be earlier than other fruit trees. The best pruning period of fruit trees is before the sap flows out in spring.
4. Hazelnut has a strong photophobia.
Because of its strong light-shielding property and high branch density, hazel trees are easy to cause branches in the inner hall to die, and some of them move outward.
5. The hazelnut tree was seriously injured.
When pruning, you should pay attention to the fact that the number of large shears and saws should not be too much. The thinning of large branches should be carried out in a planned way every year.
