How to trim the Hawthorn tree? Pruning methods are different in different growth periods!

Fruit tree pruning is a technical measure to cut off the vegetative organs of fruit trees in order to adjust the crown structure and renew the composition of branches. the pruning of fruit trees is very important, and the shaping and pruning methods are different in different growth stages. so how to prune Hawthorn trees? Pruning methods are different in different growth periods!

1. Pruning young trees

The growth rate of the young Hawthorn tree is relatively slow and weak, and it is also the slow seedling stage of the Hawthorn tree. In this stage, the pruning work is mainly based on shaping, cultivating the backbone branches, adjusting the growth direction and angle of the backbone branches, and laying the foundation for fruiting. The young trees within 3 years of the growing period should be heavily truncated and not thinned, so as to promote the Hawthorn tree to grow more healthy branches, expand the crown, improve the flowering rate, and achieve the purpose of early fruiting. If the main and lateral branches are properly truncated, the moderate branches with moderate growth should leave room for growth, increase the number of branches and fruit setting of fruit trees, and properly remove the branches that are too dense and will rob the backbone branches for nutrients.

Pruning the first fruit trees

The pruning at this stage should fix the tree shape of buying books, cultivate different fruiting branches, increase the yield of fruit trees, and prepare for the transition to high yield. the pruning direction is to sparse the branches and cultivate the fruiting branches. if the auxiliary branches seize the nutrients of the backbone branches, the auxiliary branches should be removed in time, not all of them should be removed, and the retained branches should be guided to slow growth and promote fruit. The branches that bear fruit for more than two years can be retracted in time to prevent external fruiting. The branches with sufficient growth space can be properly cultivated into fruiting branches to remove overdense and overgrown branches.

3. Pruning fruit trees

The pruning direction of the full fruit tree is similar to that of the first fruit tree, which is mainly based on the tree shape and the culture fruit mother branch, controlling the number of leaves, properly adjusting the leaf curtain surface, updating the fruit mother branch, preventing the occurrence of the phenomenon of big and small years, increasing the yield, ensuring high yield and high yield, increasing the full fruit time, the main pruning methods are short cutting, retraction and so on, so as to control the ratio of fruit branches to vegetative branches, remove peripheral branches and carry out short cutting. Thinning flowers and fruits, promoting the concentration of nutrition, promoting the development of vegetative branches, cutting off useless branches such as overlength and density, overlap and so on.

Update tree pruning

During this period, when fruit trees renew their fruiting mother branches, the growth rate of fruit trees will obviously decrease, the backbone branches will droop weakly, the leaves of inner branches will fall seriously, and a large number of overdense branches will appear, but the self-recovery ability of Hawthorn trees is relatively strong. as long as we strengthen the management of water and fertilizer, do a good job in ploughing and weeding and pruning properly, we can restore growth and prolong the life of fruit. The pruning method is usually to retract the backbone branches at all levels every year and re-culture the fruiting branches with overgrown branches.

The above is the introduction of the soil flow net to the shaping and pruning methods of Hawthorn trees in the four growth periods. Hawthorn trees are relatively tall in shape. If they are not pruned in time, the orchards are too closed, the permeability is extremely poor, and the inner branches are not illuminated enough. As a result, the flowering and fruiting rate decreases, and the planting efficiency will be greatly affected.
