Circumcision of jujube trees is very important, when is the best circumcision?

If you want to peel the ring on the jujube tree, you must not only do it well, but also understand its principle. Some growers only know that the ring is well removed, but if the method is not appropriate, the result is that the effect of the ring removal will be reduced. Peeling ring refers to peeling the stem into rings at the beginning of the sacred flame of the jujube tree or after flowering, before the fruit drop and the highest peak, blocking the phloem with tools, preventing the photopolymer from being transported to the roots, controlling the nutrient distribution of the tree and initiating to the flowers and fruits, so as to improve the fruit setting rate.

The time cannot be generalized, and it should be determined according to various factors such as the age of the tree, the strength of the tree's potential, and the flowering situation. The glow time is too early, the flowers bloom less, and the yield is reduced. The lapping time is too late, the quality of the flowers is low, the fruit development and ripening time response are delayed, and some species lack growth organs, resulting in immature fruits.

So, what is used to judge the time of the jujube tree to peel the ring? According to the reception of the jujube trees, the stronger jujube trees that grow more than 3 years and have a stem diameter of more than 3 cm are suitable for decoupling on the Holy Flame (usually from early to mid-June). How can you tell if it's flowering?

Whether there are 4 6 flowers open on most of the fruiting branches of the whole tree, as well as the period when the first flower (i.e., the hair beacon) on each flower book opens, during this period can promote the rapid flowering of the hair beacon. The cutting time of the jujube tree should be carried out in May and June, when the jujube tree is in flowering, and the fruit trees with serious flowering can be cycled at the end of the sacred fire period.

The method of circumferential cutting of jujube trees is to use a ring knife to cut about millimeters around the upper part of the old bark of the trunk, cut it into a layer of wood, cut it with a circumferential cut at a distance of 30 cm from the ground, cut a branch up to twice, and finally wrap the wound with plastic film to prevent bacterial infection and affect wound healing. The ring of the jujube tree, also known as A, is a relatively common jujube tree treatment technique. As the name suggests, the ring is to go around the jujube tree, cut the outer bark, cut the phloem, and preserve the xylem.

This prevents the roots of the jujube tree from absorbing inorganic salts and water, transporting upwards through the xylem, and the nutrients produced by the photosynthesis of the leaves from spreading through the phloem. In this way, the nutrients produced by photosynthesis can accumulate on the jujube tree, meeting the nutrient requirements for flowering and fruit development. The biggest benefit of this treatment is that it can improve the fruit setting rate of jujube trees and increase the yield.

The time when the jujube tree breaks is also important. The main purpose of jujube tree picking is to improve the fruit setting rate of jujube trees, so as to increase the yield, therefore, the holy flame machine that rings the jujube tree flowering should be chosen, usually with a flowering amount of 30% to 50%, which is the most suitable. If the first is too early, the jujube flowers have not been fully formed, and it is easy to inhibit the quantity and quality of jujube flowers, so the effect is not good.

The nail is too late, some of the jujube flowers have begun to fall off, and it is too late to open the nail again at this time.

The best time for circumferential cutting of jujube trees is the full flowering period of jujube trees, which can not only reduce flower and fruit dropping, improve fruit setting rate, but also make young fruits grow uniformly and expand rapidly, and the fruit shape is circumferential, and the overall yield can be improved.

It should be in June, at this time it is constantly growing wildly, if so, then the wound can be healed quickly, and it can play a good role, and there will be no wilting.

The best time for circumferential cutting of jujube trees is the full flowering period of jujube trees, at which time the circumferential cutting is enough to make the young fruits grow evenly and expand rapidly, the fruit shape is circumferential, the overall yield is improved, and the fruit setting rate is relatively neat.

More than three years old, the jujube tree is relatively stout. At the beginning of June or the middle of June. Circumcision is almost ready.

A few years of jujube trees can be peeled and peeled, when to dare the best.

It is best to circumferentially cut at the beginning of flowering and the peak flowering period, and then only need to be cut once a year, and the fruit growth rate will increase after circumcision, and the fruit will grow faster and better.

First, what is the circumcision of jujube trees.

The so-called circumcision is to peel off the old bark on the trunk or main branch of the jujube tree, and cut one or more knives along the trunk with a sharp knife at this part, and the circumferential cutting is completed.

Second, why circumcision.

The reason for the circumcision of jujube trees is to artificially interfere with the natural growth of jujube trees, block the delivery of nutrients formed by photosynthesis of jujube trees to the roots, and make all these nutrients bloom and shoot to ensure the nutritional needs of jujube trees for flowering and fruit setting, so as to achieve the purpose of more fruit setting and good fruit setting, and improve the yield of jujube trees.

Third, the object of jujube tree circumcision.

Fourth, the technical operation of circumcision.

The circumcision or ring stripping of jujube trees is not how to cut (peel), how to cut (peel), it has certain technical requirements.

Position of circumcision:

The position of the ring stripping must be more than 30 cm from the ground.

Knife edge depth for circumcision:

Circumcision and ring stripping are best done at such depths as to achieve the xylem without harming the xylem. And the knife edge is smooth and there must be no burrs. The joint cutting line should be aligned and not wrong. Otherwise, the circumcision effect will not be achieved.

Width of the circumferential cutting edge:

The width of the ring cutting edge is generally the width of the cutting edge of the ring cutting tool, and the width of the ring cutting edge is not more than one-tenth of the tree diameter, and the maximum width is not more than 1 cm.

Protection of the circumferential cutting knife edge:

Half a day after circumcision (peeling), apply 5% fipronil 500 times or 30% acemethamidophos 300 times on the incision, and then wrap the incision with plastic film and tie it tightly to avoid insect infestation.

In short, the circumferential cutting (peeling) of jujube trees requires both a good grasp of time and a good technique, and only in this way can good results be achieved.

Early flowering to full flowering. The jujube tree can be circumcised at the early flowering stage and the full flowering stage, and the jujube tree at this time has strong fertility and can be repaired quickly.

The full flowering period of jujube trees, because this time ring cutting can reduce flower and fruit fall, improve fruit setting rate, and can also make young fruits grow evenly and expand rapidly, and the fruit shape is circumferential, and the overall yield can be improved.

Jujube trees in the process of breeding, need to be circumcised, it is recommended to be circumcised in the flowering period of May and June, can increase the fruit yield of jujube trees, first need to extend the lower part of the trunk distance of 30cm, peel off the bark of the old warp tree and remove it, and then cut the other end of the ring twice, wrap the wound with plastic film, and wait patiently for the wound to heal.

In the process of breeding, the jujube tree needs to be circumcised, so that the jujube tree can better absorb the nutrients in the soil, so when is the best circumcision of the jujube tree, it can be circumcised during the flowering period of the jujube tree in May and June, which can increase the yield of the fruit of the jujube tree and is conducive to the growth of the jujube tree.

First of all, you need to prepare a special sharp scissors, disinfect the scissors with alcohol, first extend the lower part of the trunk to a distance of 30cm, peel off the bark of the old warp, and then peel off all the parts of the old warped bark, and cut two circles at the other end of the trunk to expose the ring-shaped tender skin.

You can spray carbendazim on the wound and wrap it with plastic film, which can avoid bacterial infection at the wound site, so that the wound will rot and affect the normal growth of the jujube tree in the soil.

Whenever the jujube tree is circumcised, it is necessary to apply a large amount of fertilizer, keep the soil moist, and place it in a astigmatism environment to promote faster healing of the wound, but do not sprinkle water and fertilizer on the plant, which will cause the wound to rot and affect the growth of the jujube tree in the soil.

Circumcision of jujube trees can promote better fruiting of jujube trees, help the development of young fruits of jujube trees, and reduce flower and fruit drop in the process of growth and development of jujube trees. Circumcision is generally only suitable for strong trees with a trunk diameter of more than 6 cm, and is not suitable for weak, young or old trees. For varieties with severe flower loss, circumcision can be performed at the end of their flowering period, as this can reduce the shedding of young fruits.

1. What is the role of jujube tree circumcision?

1. Circumcision of jujube trees can make it produce better results, help the development of young fruits of jujube trees, reduce flower and fruit drop in the process of growth and development of jujube trees, and improve the yield of jujube trees, the quality and nutrition of jujube trees, so it is necessary to circumferentially cut jujube trees.

2. Circumcision is generally only suitable for strong trees with a trunk diameter of more than 6 cm, and is not suitable for weak trees, young trees or old trees. For strong trees, circumcision can prevent the delivery of nutrients to the roots, allowing more nutrients to bloom and pollinate, thereby increasing the fruiting rate.

3. Generally, for varieties with serious flowering loss, circumcision can be carried out at the end of their flowering period, which can reduce the shedding of young fruits. However, circumcision must be paid attention to, otherwise it will not only not increase the yield of jujube trees, but also cause the tree to weaken.

Second, the time and method of jujube tree circumcision

1. Most of the time choices for circumcision are the early flowering period or the full flowering period, because at this time, about one-third of the flowers of the whole tree are opened, and it can also be circumcised when 4-5 flowers bloom on most of the jujube hanging, which is the best period for flower quality, and the number of fruit sets is also relatively large, the size is large, the maturity period is consistent, and the commodity value is high.

2. Prepare tools before circumcision, mainly including sickles, armor openers, ring strippers, etc. The market is generally used multi-functional jujube tree nail opener, which is mainly composed of a handle, three U-shaped knives and a sharp knife head, the large U-shaped knife can scrape off the old bark, the small U-shaped knife is used to open the armor, and the sharp knife head is used to shovel the stubble and repair the gap.

3. When circumcising, first peel off the bark of the lower part of the trunk, then peel off the part of the old warped bark, use a sharp knife to circumferentially cut around the trunk 2 times, peel off the annular tender skin, and finally use plastic strips to bandage the wound. In this way, the infection of germs can be prevented, which will affect the re-healing of the wound.

Jujube trees are circumcised in May-June.

Jujube tree circumferential cutting needs to be carried out on a sunny day, at a distance of 30 cm from the ground, select a smooth and thornless place with the main trunk, use a knife to remove a circle of old bark about a circle of hungry Hu centimeters wide, and then at the place where the old bark is removed, use a knife to circumferentially cut two times around the trunk, deep to the xylem, and peel off the annular tender skin, which is about 5 mm wide.

When circumcising the jujube tree, it is required to use sharp tools, so that it can be easier to circumcis, and the wound of the jujube tree can be smoothed a little.

Jujube tree in the ring cutting, should not be carried out in rainy weather, after the ring cutting, need to use plastic film to wrap its wound, so as to avoid its wound contact with water after decay, after the maintenance of the jujube tree, need to strengthen the management of water and fertilizer, to promote the jujube tree can grow vigorously.

Causes of circumcision of jujube trees

1. The main purpose of jujube tree circumcision is to improve the fruit setting rate, the key to the fruit setting rate of jujube trees, the key lies in the balance of vegetative growth and reproductive growth of jujube trees.

2. Through circumcision, the channel of nutrients to the root system and the lower tissue in the phloem tissue of the jujube tree is cut off, so that the products of photosynthesis are concentrated in the canopy, providing sufficient nutrients for the reproductive growth of the jujube tree, thereby improving the fruit setting rate, promoting the rapid growth of young fruits, and reducing the physiological flower and fruit drop caused by nutritional imbalance.

Why doesn't <> jujube tree circumcision die? Jujube tree circumcision is a technical work, both the time and width of circumcision must be mastered in order to achieve the expected results. Below we introduce the best time for jujube circumcision and other related issues for reference.

1. Jujube trees are generally in the early stage of full flowering or full flowering period, about 30-35% of the whole plant or most of the jujube hanging about 4-5 flowers, and the average daily temperature is about 25.

2. According to the survey, in mid-June, the average temperature was circumcised, and the fruit setting rate was about 2%;

At the end of June and the beginning of July, the average temperature was circumcised, and the fruit set rate was about 23%;

In mid-to-late July, circumcision is performed at the last temperature, and the fruit set rate is about 38%.

Therefore, the circumferential cutting time also needs to be adjusted according to the air temperature.

Objectively speaking, the circumcision of the jujube tree is a kind of injury to the jujube tree, if the circumcision is too wide and the damage to the jujube is too heavy, the jujube tree will die.

We circumferentially cut the jujube tree, which is based on the degree that the jujube tree can tolerate injury, and it cannot exceed one centimeter, otherwise the wound will not heal well, and it will inevitably die, and it cannot be treated.

Jujube circumcision is generally after flowering, and it is better to circumcision around June 10 of the solar calendar, when the wound is most likely to heal.

Circumcision is carried out during the flowering period, which cuts off the channel for the trunk phloem tissue to transport nutrients downward, so that the photosynthetic products synthesized by the upper leaves of the jujube tree cannot be transported downward and are concentrated in the canopy position, which fully develops flowering, fruit setting and young fruits, thereby improving the fruit setting rate and reducing flower and fruit fall.

Circumcision of jujube trees can make them produce better results, help the development of young fruits of jujube trees, and improve the yield and quality of jujube trees. Yu Zao specifically:

1) Circumcision can promote fruit setting and young fruit development of jujube trees, improve the fruit setting rate of jujube trees, and reduce the phenomenon of flower and fruit dropping.

2) Circumcision adjusts the shape of the fruit to be more round, and it also increases the soluble solids content (approximately) as well as the total sugar content (approximately.

1) Preparation tools: the main tools are sickles, armor openers and ring cutters, etc., at present, the most used is a multi-functional jujube tree armor opener, which is composed of a handle, three U-shaped knives and a sharp knife head

The large U-shaped knife can be used to scrape old bark, the small U-shaped knife can be used to cut the armor (circumcision), and the pointed knife head can be used to remove stubble and repair chips.

2) Circumferential cutting method: peel off the bark of the lower part of the trunk, then peel off the part of the old warped bark, and use a sharp knife to circumferentially cut around the trunk twice, deep into the xylem, and peel off the annular tender bark.

Finally, the wound was bandaged with plastic plum void as a rubber strip to avoid the invasion and infection of germs and affect the wound healing again.

1. Circumcision may lead to damage to the root growth of jujube trees, reduce the absorption capacity of roots and the ability of the tree to resist stress, and also cause the occurrence of yellow leaf disease, scab disease and anthracnose of jujube trees.

2. Circumcision is only suitable for strong trees with a trunk diameter of more than 6 cm, and is not suitable for weak, young or old trees.

3. Circumcision should be combined with management measures such as fertilizer and water, foliar spraying, pruning, and pest control.
