When is the best time to prune an orange tree? What are some tips when pruning?

Delicately managed citrus orchards that can be pruned all year round. Due to the different growth and development of citrus trees in different seasons, the types of branches pulled out are also different, and the purpose of pruning is also different. Pruning can be carried out in different periods.

In general, the pruning time is divided into winter pruning and growing time pruning.

Winter pruning. Winter pruning is carried out from the collection of fruit to the following spring, before germination. At this time, citrus plants are in a relatively dormant state, and their physiological activities are weakened, and the loss of nutrient modification is small.

The faster the area damaged by citrus frost in winter is repaired, the faster the wound will heal and the better the effect. Citrus producing areas in the East China Sea can be pruned before spring buds sprout after the temperature rises and warms in the spring.

Winter pruning can regulate the nutrition of the trees, restore the trees, restore the momentum of the trees, coordinate the relationship between growth and fruiting, so that the late spring drawn in the second year bears fruit and the flowering period is abundant. Re-spawning old trees, weak trees or sprouting trees need to be re-cut down, and after germination in late spring, they retreat, and after re-cutting, there are many new shoots, sturdy, and crowns.

The recovery is fast and the update effect is good.

Prune the growth phase.

With the development of production and the progress of science and technology, the pruning of the growing season has been strengthened in recent decades, which has obvious effects such as promoting the growth of seedlings, improving the fruit setting rate, promoting the differentiation of flower buds, prolonging the years of the wind mountain, and restoring trees.

Growing pruning refers to all kinds of pruning from the end of spring after flowering to fruit pickingDuring the growing period, citrus grows vigorously, has active physiological activities, responds quickly after pruning, and grows in large quantities. It has a good effect on the renewal of old trees and weak trees and the pulling of new shoots.

Spring pruning is done in late spring when thunder is vivid. Purpose to adjust spring grass.

The ratio of flower buds and oil fruits prevents spring grass from being overly vigorous and aggravates flower and fruit drop. At the same time, for the trees that bloom too much, cut off the flower branches again to reduce the excessive flowers and young fruits. China's Yangtze River Basin.

Since the 80s of the 20th century, the citrus producing areas have short-term high temperatures above May and June, Wenzhou citrus and navel oranges.

and so on sweet orange plentiful drop. Through pruning measures, a certain amount of shoots were eliminated in spring, the proportion of new and old leaves of plants was adjusted, the high temperature fruit drop was reduced, and the fruit setting rate was improved.

Summer pruning refers to pruning around the second physiological fruit drop period from May to June. Young trees rub buds, cultivate stems, fruiting trees clear late summer, reduce physiological fruit drop, king trees in late spring to leave 25-30 cm long hearts, long branches strong, summer pruning is mainly for the purpose of fruit preservation, restoration, maintain tree growth momentum, etc.

"Autumn pruning" refers to pruning in July after the fruit is firmly seated. The main purpose is to cultivate excellent fruiting seedlings and promote flower bud differentiation. This includes wiping the buds and sowing seeds in time to cultivate more robust late autumn seedlings.

Ignore smuggling and inappropriately located late autumn to avoid too many or too thin seedlings. Measures such as circumcision of large branches and root cutting were taken to promote the differentiation of seedlings and flower buds. Continue to neglect excess fruit, improve and enhance fruit quality, or improve the summer long end of short fruiting hairy branches and young trees, make basal sprouts fruiting hairy branches, etc.

Pruning is carried out after the fruit is harvested. Use sterilized scissors to prune off some yellowed branches and old branches. Dry the wound as soon as possible after pruning. Usually during the plant maintenance period, the plant should also be regularly topped.

Spring pruning, the main purpose is to control the tree body to grow too vigorously, consuming too much camp Winter pruning is relatively small, generally pruning off diseased branches In the center of the canopy, cut off 1 or 2 large branches, leaving a "sky window". This pruning has two benefits, one is that it can dwarf the canopy, and the other is that it is easy and quick, choose large branches to cut off, leaving more space for sunlight and ventilation.

Pruning is best between February and March in the spring, you need to pay attention when pruning, be sure to cut off dead branches, but also reduce cross branches, old branches, too dense places to prune a little.

It is good to prune the branches of orange trees in the spring and summer of each year, because spring pruning can control the tree momentum of the plant, reduce the contradiction between vegetative growth and reproductive growth, in order to achieve the purpose of high yield, and summer pruning can promote the orange tree to germinate more new branches, and when pruning, use sterilized scissors to avoid wound infection with germs and affect the healing speed.

Orange trees are well pruned in spring and summer every year, because spring pruning can control the strength of the plant, Pison reduces the contradiction between vegetative growth and reproductive growth to achieve the purpose of high yield, and summer pruning can promote orange trees to germinate more new branches, thus producing a large number of fruiting branches.

In the process of pruning orange trees, it is necessary to use sharp scissors to eliminate the poison of potatoes to cut off the branches that affect the growth of the plant that are too long, too dense, and sick, so as to reduce nutrient consumption and promote the centralized supply of nutrients, which is conducive to the growth of orange trees.

When the pruning of the orange tree is completed, the wound should be disinfected, the wound can be sprayed with fungicide, or applied plant ash, and the amount of water and fertilizer can be controlled to avoid excessive application, which will affect the healing speed of the wound and the growth and development of the plant in the later stage.

Overview of the orange tree.

The orange tree, a citrus plant of the Rutaceae family, is native to China and is widely cultivated in the provinces south of the Yangtze River. It is about 3 meters tall and blooms in spring and matures in October-December. It prefers warm, moist environments, so it is hardy.

Orange tree pruning time.

1.Spring pruning: Orange trees can be pruned in spring March.

Prune off pest and disease branches, clumping branches, dead branches, dead branches, and dense branches, mainly pruning dead branches and clumping branches to increase light transmittance. This kind of feast should be pruned lightly, and watering and fertilization should be timely. 2.

Summer pruning: The treetops of orange trees can be wiped off in June. If the position of the long idiot is not ideal, it is advisable to wipe them off.

The number of summer shoots is small, but they grow fast, grabbing fertilizer and water, affecting the shape of the tree. As a result, too many trees had to be cut down in time. 3.

Autumn pruning: September to October. Where you want it to grow autumn buds, it's best to cut it short.

Where you don't want it to grow leaves, you can cut it thinly, clump branches, and cut it off. If it's too long, you can prune it a little to develop a robust fall shoot. 4.

Winter: In winter, orange trees go into hibernation. After the fruit is harvested in autumn, the tree has not yet recovered.

If it is not insect branches or dead branches, try not to prune.

Orange tree pruning method and steps.

According to the actual situation of orange trees, the methods of pruning, thinning, shrinking, twisting and rubbing the tips can be used to cut off some branches and promote branching. In addition, excess dense weak branches, clumps and overgrown branches should be cut off to increase the ventilation and light transmission of the plant, which is conducive to flowering and fruiting. The tip of the orange tree can be retracted, and the heavier the retraction, the stronger the germination and growth of the pruned branches.

Twisting branches is mainly to stop nutrient transport by damaging branches, thereby slowing down the growth rate, promoting flower bud differentiation and increasing fruit yield.

Orange tree pruning precautions.

It should be noted that orange trees should be treated once before pruning to prevent pests and diseases such as psyllids and spider mites. After pruning, it should be treated again in time to allow the tree to heal the wound. Such as mancozeb, prochloraz and other agents for the prevention and treatment of anthracnose.

1. How to prune and shape small orange trees.

2. How to prune orange trees.

3. How to prune orange saplings.

4. How to prune small orange trees.

1.When the small orange tree grows to about 1 meter, it needs to be topped to control its height well.

2.By the way, the messy branches and dry branches should be cut off.

3.During the growth period, it is necessary to cut off overlapping branches, overly dense branches, and cross branches in time, and cut them from the base.

4.Pruning during the fruiting period does not bear fruit, is infected with pests and diseases, and weak branches reduce nutrient consumption.

5.You can also shape the plant according to your favorite shape to make it more beautiful.

Techniques of orange tree pruning and pruning: seedling pruning source redressing, fruit pruning, and pruning.

1. Seedling pruning: When the seedlings are one meter high after the seeds are sown and germinated, the plants should be pruned, the branches and leaves of the plants should be pruned off, and the branches and branches of the plants should be cut off, and the main branches of the plants should be retained, otherwise the growth of the plants will be affected.

2. Pruning during the fruit period: pruning the branches of the plant during the fruit period, the branches that cannot bear fruit should also be cut off, and the branches that are weaker and infected must be cut off, so that the plant can grow new branches, produce more fruits and better quality.

3. Refurbishment: After cutting the branches of the plant, the plant should be renovated according to the shape of the plant, so that the plant is more beautiful. Renovation during this hail stove can also prevent the plant from consuming nutrients and affecting the plant fruit; With nutrients, the plant can be more robust and can also prevent pests and diseases.

Orange Tree Planting Method:

If you want to plant orange trees, you must first prepare the soil suitable for its growth and development, rooting, this plant has slightly higher requirements for the soil, so it is necessary to use humus, garden soil and sandy carbon soil for mixing, so that the soil is loose and porous, strong drainage and air permeability, the overall acidity and a certain basic fertility.

Like most fruit trees, orange trees also have a variety of different planting methods, including sexual propagation planted with seeds, and asexual propagation propagated by cuttings, both of which have their own characteristics, seed seedlings are suitable for use as rootstocks, and cuttings can completely retain the characteristics of the female parent.

After the citrus tree entered the senescence stage from the full fruiting stage, the vegetative growth was very weak, the senescent branch group increased, and the yield decreased. Regeneration pruning is the process of cutting off the senescent parts of the tree to encourage it to form a new crown to increase the productivity of the old tree. In general, in addition to canopy renewal, root regeneration should also be carried out, and sufficient fertilizer should be applied to promote its growth.

Regeneration pruning should be done in different ways depending on the degree of decay of the plant

1) Rotation update method. The rotational update method is also called the local update method. For old trees with some branches declining and some branches still bearing fruit, the 3 4-year-old side branches that have partially declined can be truncated first, and all canopies can be rotated and renewed in a planned manner within 2 3 years.

This method still has a certain yield in the next few years of the update, and the yield can be gradually increased after the update.

2) Explicit renewal. The explicit renewal method is also called the light renewal method. For senescent trees that bear little or no fruit, the 5 or 7 level branches are truncated, and the crossed, overlapping branches are removed, which is called explicit renewal.

This method can make the strong branches of the current year be extracted, and the weak branches that are too dense and the long branches can be thinned out in time after the shoots are drawn, and the yield can be restored from the second year.

3) Main branch renewal method. The main branch renewal method is also called the re-renewal method. Some old trees are very declining, and the branches are damaged by diseases and insects, but the lower part of the main backbone branches is still good, the main backbone branches can be truncated with strength, and the weakly curved and knotted large branches can be deleted on the retained backbone branches.

This method allows it to produce strong shoots in the current year, start to bear fruit in the second year, and gradually increase the yield after the third year.

4) Root renewal. As the above-ground part is renewed, the underground part must also be renewed accordingly. Generally, the underground can be dug up at the drip line around the canopy, the rotten and declining roots can be cut off, and after 2 days of exposure, the grass ash is sprinkled on the cut roots, and the well-rotted high-quality compost or green manure is applied to improve the soil and promote the occurrence of new roots in large quantities.

The above several renewal methods are best carried out before the germination of spring buds, when the sunlight is not strong, there are fewer diseases and insects, and the shoots are neat after renewal, and the new shoots can be drawn 2 or 3 times in the year, which is conducive to the rapid restoration of the canopy. Secondly, to be successful, it is also necessary to pay attention to the pruning method, cut or saw without hurting the cortex below the cut, the cut should be flat, after pruning, the wound should be coated with wax, and then the main trunk and large branches should be bandaged with straw. After the shoots are removed, unnecessary sprouts are removed, the overly long shoots are topped, and sprayed to protect the new shoots, especially the prevention and control of diseases and citrus psyllids.

Strengthen fertilizer and water management, otherwise, the intended effect will not be obtained.

The pruning techniques of kumquat are as follows:

1) Pruning of young trees: young kumquat trees should be pruned lightly. Generally, only long branches, dead branches, diseased branches and sprouting tillers are removed.

2) Pruning of senescent branches: After kumquat enters the peak fruiting period, the senescent branches that have lost their fruiting ability on the periphery of the canopy can be cut off from the base to restore the tree's potential.

3) pruning of green branches: kumquat in the full fruiting period, the new shoots drawn in that year, except for the long branches, are generally not long, some in the same part of the apex to draw 2 3 branches, and the length is different, for this kind of branches of the same level, you can use the method of leaving strong to weak, and delete a part. Soft shoots that do not reach lignification in winter can be pruned from the base.

4) Pruning of long branches: The long branches of kumquat mostly grow on the backbone branches, which can be more than 1 meter long and have thorns. The long branches tend to be bare in the middle and lower parts, and often sprout into broom branches at 1 3 points at the tips of the branches, which not only disturb the shape of the tree, but also cover the other branches.

For long branches, except for those that need to be left to supplement the canopy vacancy, they should be cut off from the base, and it is best to erase them in time when the young shoots or shoots are young, so as not to consume nutrients.

5) Pruning of fruiting branches and fruiting mother branches: The fruiting branches of kumquat are still green and stout due to the developed conduction tissue, and do not need short pruning because of the short branches, and the dense and weak flower-falling branches can be thinned.

6) Pruning of dead branches, diseased branches, and dense cross branches: For such branches, they should be thinned from the base. Dense cross branches are thinned around the branches, and those with vacancies can be appropriately retracted.
