    When will the jujube tree be stripped for the operation, the Agricultural University can not give the accurate time, it is not the agricultural university does not understand the ring stripping technology, the agricultural university has many years of garden management work experience, how can there be no understanding of the ring stripping technology. It's just that the ring stripping time of jujube trees depends on different varieties and regional environments.

    First, the time of ring stripping should be treated differently because of the tree, so to speak, the ring stripping time of jujube trees is usually selected in the early flowering stage of jujube trees, but for jujube trees with serious flower and fruit drop, they should be treated separately, and the former chooses ring stripping at the beginning of the flowering period, which can improve the fruit setting rate; The latter can be ring-peeled at the later stage of flowering, which can reduce fruit drop.

    Second, the position of the ring stripping for the jujube tree ring stripping can be carried out at noon in good weather, the ring stripping of the main rod can be carried out at a position of about 20 cm from the ground, and the ring stripping on the branch can be carried out at a position of about 10 cm at the base of the branch, if it is to choose the ring stripping technology every year, then it is carried out at about 5 cm from the position of the ring stripping of the previous year every year, and so on.

    Third, the width and depth of the ring stripping operation must master the width and depth, as well as the cutting method of the operation, for the general adult jujube tree, the width of the ring stripping is about 5 mm, the depth is close to the xylem of the jujube tree, and can not hurt the xylem. Do not leave residual skin in the peeling part of the ring peeling, the peel should be closed in an annular shape, some fungicides and pesticides can be applied on the peel, and then the plastic film is taken to wrap it, under normal circumstances, the peel will heal in about a month after ring peeling.

    Fourth, the object of ring stripping technology is not suitable for any jujube tree, it is best to take ring stripping technology for relatively large vigorous jujube trees, such as for jujube trees that are more than seven or eight years old, the jujube trees that grow too vigorously can take ring stripping technology, but for young jujube trees, or the tree growth is not vigorous, then try not to do ring stripping first.

    For the jujube trees after ring peeling, it is necessary to strengthen the management of water and fertilizer, provide sufficient nutrients and water, enhance the tree potential, and promote high yield.

    <>1. The best location: The ring stripping of jujube trees is generally carried out at 20-30cm from the ground from the trunk, and then moves up 3-5cm every year until the main branch is forked, and then peels from the base of the strong branch 5-10cm to the upper ring. 2. The best timing:

    Jujube tree ring stripping is generally carried out at the early stage of full flowering or full flowering period, or when the whole jujube tree blooms about 30-35%, or most of the jujube trees bloom about 4-5 flowers.

    1. The best location and timing of jujube tree ring peeling

    1. The best location.

    Jujube tree ring stripping is generally carried out at a distance of 20-30cm from the ground to the trunk, and the old bark at the ring peel is scraped off first, and then the ring stripping knife is used to circumferentially cut two knives on the exposed pink phloem tissue (deep to the xylem, but not to the xylem), and then the phloem in the ring strip is peeled off. In the subsequent years, the position of the ring stripping is moved up 3-5 cm on the basis of the previous year's ring stripping position until the main branch is forked, and then from the base of the strong branch 5-10 cm to the upper ring peeling.

    2. The best timing:

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

    2) Ring peeling is generally selected to be carried out on a cloudy day or a sunny day, if the ring peel is carried out on a rainy day, it is necessary to apply thiophanate-methyl 800 times solution on the wound to protect it from infection.

    Second, what is the role of jujube tree ring stripping?

    1. Function. (1) Ring stripping 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) Ring peeling can adjust the shape of the fruit to make it more round, and it can also increase the soluble solids content (approximately) as well as the total sugar content (approximately).

    2. Principle. Ring stripping 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 crown position, so as to fully develop flowering, fruit setting and young fruits, thereby improving the fruit setting rate and reducing flower and fruit drop.

    3. The disadvantages of ring stripping.

    Ring stripping may lead to damage to the root growth of jujube trees, reduce the absorption capacity of the root system and the stress resistance of the tree, and also cause the occurrence of yellow leaf disease, scab and anthracnose of jujube trees, so the time interval of ring stripping must be adjusted according to the growth of jujube trees (if the tree is very weak, it will not be circumcised for two years, and if the tree is moderate, it will be circumcised once every other year).

    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.

    Please see question 2: How to circumferentially cut jujube trees that have been planted for two years? 10 points The two-year-old floating tree is still small, and the circumferential cutting is no problem, and the method is to cut the bark through with a knife from 10 cm above the ground, deep into the xylem, and circle along the dry week.

    Generally, when the thickness reaches more than 5 cm, ring stripping is advised.

    Question 3: Why do jujube trees circumferentially cut the bark of jujube trees to prevent nutrients from returning to the roots and improve the pollination and fruit setting rate.

    Question 4: When will the jujube tree be circumcised Ring stripping during the full flowering period, generally in early to mid-June.

    Question 5: Why should jujube trees be cut Jujube trees are vegetatively grown before flowering and fruiting, enter reproductive growth during flowering and fruiting period, and block part of the nutrient delivery after circumcision to promote flowering and tooth differentiation and improve fruit setting rate.

    Question 6: What is the difference between circumcision and circumcision of jujube trees The difference between circumcision and circumcision of jujube trees is:

    Annular peeling is annular peeling; Circumcision, also known as annular cut, involves the cutting of one or more rings across a branch, down to the xylem. Compared with circumcision, the weakening effect of annular stripping on tree potential is more obvious.

    Ring stripping and circumcision destroy the normal nutrient exchange of the tree, prevent the transportation of nutrients and hormones up and down, and the growth of the roots is temporarily stopped due to the lack of nutrients and hormones, and the absorption is weakened, which can promote the accumulation of carbohydrates above the ring stripping and ring cuts, and reduce the content of growth hormone, thereby inhibiting the vegetative growth of the new shoots of the year, promoting reproductive growth, and is conducive to the formation of flower buds and improving the fruit setting rate. Jujube trees are generally circumcised or circumcised in early to mid-June (early flowering stage), which can inhibit vegetative growth, increase fruit setting rate and promote flower bud differentiation.

    Precautions: First, ring stripping and circumcision should not be the same, and should be carried out on the main branch and auxiliary branches. The trunk ring exploits the weak tree too much, and should be used with caution according to the tree potential.

    Second, the width of the ring stripping is generally 1 10 of the diameter of the treated branch, the method of taking the bark must pay attention to the cambium layer can not be destroyed, the ring stripping should not be too deep or too shallow, too deep to hurt the xylem, destroy the cambium parenchyma cells, the wound can not be healed in time, seriously inhibit the growth potential of the tree body or branches, and even lead to the death of the tree; The shallow phloem remains, and the effect is not obvious. 1-3-year-old jujube trees should generally not be circumcised or annularized, so as not to affect the growth of the tree.

    1. Open the nail, temporarily cut off the phloem of the main trunk or branch of the jujube tree, and the essence of the nailing is to intercept nutrients.

    2. Because the organic nutrients produced by photosynthesis in the leaves of the jujube tree and the amino acids converted into them are transported to the flowers, fruits, trunks and roots through the sieve of the phloem.

    3. After the front of the car is opened, the passage to the root or other branches is cut off for a period of time.

    4. In this way, the organic nutrients can be effectively accumulated in the closed-code clear tree body above the first mouth, so that the nutrients of leaves, flowers and young fruits are relatively abundant.

    5. It can not only improve the yield of jujube trees, but also enhance the tree potential of jujube trees.

    Jujube tree circumferential cutting: peel off the bark of the lower part of the trunk;

    Then, at the part where the old warped skin is peeled, the trunk is circumferentially cut twice with a sharp knife, reaching deep into the xylem, and the annular tender skin is peeled off, which is about 5 mm wide;

    Finally, the wound is bandaged with a thin plastic strip to prevent the invasion of germs and soil infection that may affect the normal healing of the wound.

    After the main trunk of the jujube tree is cut and stripped of a ring of bark, the channel of nutrients transported from top to bottom is temporarily interrupted, so that a large amount of nutrients are produced by leaf photosynthesis.

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. >>>More
