How to prune oranges in different periods? Young tree pruning 1, coring in time.
Shoots are picked in spring to promote the growth of shoots in early summer. Leave 6-8 leaves for coring in early summer, so as to ensure that 12- 14 leaves can core in summer and cultivate fruiting branches. Picking flower hearts in autumn can promote the senescence of flower buds before physiological differentiation. Usually leave 6-8 leaves.
2. Spread buds and buds.
In order to promote the production of fruiting mother branches, it is necessary to wipe flower buds and prune young trees to cultivate good fruiting mother branches. Usually, buds smaller than 2 cm are erased until the branches are released. Can make the hair of the fruiting mother branch more tidy. In addition, we should pay attention to a large number of fertilization and watering, increase phosphorus and potassium fertilizer, and promote flower growth.
3. Summer buds and autumn buds
Cut the summer shoots short two months before the physiological differentiation of flower buds, so that the extracted autumn shoots can easily become fruiting mother branches.
Fruit tree pruning 1, pruning branches
In the fruiting period, it is easy to extract immature long branches, which should be pulled out in time.
2, branch rotation compression pruning
After fruiting, the branches or mother branches are cut short at the base, leaving one branch at the incision and 1-2 buds on the branches. Let it sprout, blossom and bear fruit in the second and third years. The results show that the branch group is updated and more results are obtained by using the short-cut method. If the external bearing capacity of the crown is strong, it needs to be retracted and updated, and the short section needs to be updated, so that the crown is in a state of being heavy on the top and light on the bottom, and the external weight is light on the inside.
3, summer and autumn shoot pruning
For plants with medium tree potential, methods such as weakening, keeping in the middle and cutting strength are used to prune summer and autumn branches, remove summer and autumn branches and reduce the loss of flowers and nutrients. As the mother branch of the fruit, the golden branch can be effectively cut and promote the extraction of ready-made branches.
4. Prune the fruiting mother branch
Results After the mother branch is mature, it is generally not suitable to take shortcuts because the bud is at the top. When the mother branch bears fruit, the weak branches can be removed, leaving 1-3 strong branches. If there are too many fruiting mother branches on a tree, a part can be cut short as spare branches to keep the balance between fruiting and growth and prevent the phenomenon of fruiting in different years.
What should I pay attention to when pruning oranges? 1. You must be familiar with the variety before pruning. For example, Satsuma mandarin (most Japanese varieties) should be lightly cut, and its long branches have the ability to bear fruit continuously, so it is necessary to keep more seeds. For those that are too droopy, they can be cut short at the strong buds (or branches), and for dense branches and combined branches, the weak can be removed and the strong can be retained. The red orange is mainly thinned, and the pruning amount should not be too large.
2, pruning should be combined with the age of the tree. The combination of young trees and shaping, mainly short cutting, supplemented by thinning, promotes branching and accelerates tree cultivation. For adult trees, the existing trees should be maintained.
How to increase the yield of citrus is a unique problem faced by many people today. In order to achieve a double harvest of citrus yield and quality, it is necessary to do a good job in soil, fertilizer, water, seed, plant diseases and insect pests, branch management and so on.
