Does pecan circumcision have an effect on trees?

Due to the large duct and strong root pressure of walnut, the wound flow is large. Its wound fluid contains a large amount of soluble sugar, nitrogen, mineral elements and a variety of amino acids, as well as a small amount of phenolic substances and trace amounts of walnut quinone. Excessive wounds and nutrient loss cause the tree to weaken and even die of branches.

The time of the general injury flow starts from the beginning of November, and by mid to late November, with the pouring of frozen water, the injury flow increases sharply and reaches its peak. From the end of December to mid-March of the following year, injuries rarely occur. The flow of injuries then began to occur again and gradually increased, reaching a second peak from the end of March to April.

Thereafter, as the sprout grows, the wound flow gradually decreases;

Walnut circumcision period to avoid the peak of the wound flow, there are mainly two periods, one is in the winter dormant period, although there will be a wound flow at this time, but the components of the wound flow are almost all water and a very small amount of minerals, if you avoid the peak of the wound flow will not have much impact on the tree. Another period is in May, which is also a better period for circumcision.

Ring cutting of hickory has an impact on the tree, which will cause the yield of pecans to be reduced, affect the yield, and will also cause pests and diseases, affect the flowering and fruiting of pecan trees, and ring cutting will also cause hickory only long branches and leaves without flowering and other hazards.

Hello, ring peeling in general in walnut trees.

On the main trunk, ring stripping is easy to affect the tree body, it is recommended that you use the flower-promoting Qiwang No. 2 instead of ring peeling to promote the differentiation of flower buds in the hood slippery ling, and at the same time spray Zhuangguo Tiling to thicken the fruit pedicle before flowering, young fruit stage and fruit expansion period of walnut trees to improve nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits, so that the fruits are beautifully colored, the fruit shape is beautiful, and the taste is good. And with the spraying of 800 times of the new high-lipid film, it can play the role of liquid film bagging, which will not affect fruit respiration, prevent fruit rust, prevent fruit cracking, improve the coloring and brightness of the fruit surface, reduce residual toxicity and improve quality.

Walnut Tree Fertilization Management:

1. Base fertilizer: The base fertilizer should be done early, which should be completed after harvest and before the fall of leaves, and each adult tree should be applied with organic fertilizer or use microbial agent to enhance soil permeability and activity.

2. Top dressing: The suitable period for top dressing is three periods: before flowering, young fruit expansion and fruit hard core, it is recommended to use water-soluble fertilizer to promote the growth of walnut trees.

3. Foliar spraying: the spraying period is the flowering period, the new shoot speed long-term, the flower bud differentiation period and after harvesting, and the commonly used types of fertilizer spraying are marine fertilized boron fertilizer and powder potassium dihydrogen phosphate.

Chelation of trace elements.

Water-soluble fertilizer.

Summary. The best time for walnut circumference is generally in May in the spring or December in the winter. Circumcision during these two time periods is less likely to harm walnut trees.

In addition, the circumcision of walnut trees can effectively control the growth of the root system and concentrate nutrients on the upper branches.

The best time for walnut tree circumcision is generally in May or December in winter. Circumcision in these two time periods is less likely to hurt the walnut tree. In addition, the walnut tree is circumcised, which can effectively control the growth of the root system and concentrate the nutrients on the upper branches.

How to promote flowers, fruits.

Spraying 300 times the solution of borax or boric acid during the full flowering period of walnut trees can improve the fruit setting rate.

Time slots are not allowed. The suitable time for ring stripping is from May to June, and the walnut tree is resolutely not able to move the scissors on the branches of the tree during this time period, because the walnut tree flow pressure is strong, when the branch is damaged, a large amount of nutrient solution outflows, greatly artificially weakening the tree, if the damage is too much serious and the tree body dies, just like people cut the arteries and bleed more than exhaustion. The best time for walnut tree pruning is selected from cold dew to the beginning of winter, during which the walnut tree has little wound flow, and the loss of tree body fluid, that is, nutrient solution, is small, which greatly ensures that the tree is strong and resistant to diseases.

The main reason for the elimination of ring stripping of walnut trees is two:

Hair-prone a** is not allowed. Walnut tree is very prone to root rot, branch rot if poor management, May and June is the high incidence period of this disease, if the walnut tree is stripped of the ring, block the nutrient delivery to the root, so that the root nutrition can not be supplied, the root will be in a half-dead state, so that the tree potential is greatly weakened, it can be said that it artificially increases the occurrence of root rot, and when it is serious, the whole plant dies. The wound caused by the ring peeling is also artificially increased to the occurrence of branch rot.

If a sturdy tree is artificially half-dead or even dead, then ring peeling and cutting are the culprits!

There are three main reasons for the elimination of ring stripping of walnut trees

Peculiar physiological habits do not allow. The physiological habits of walnut trees: oil nuts, large fertilizer requirements, long branches, flat branches and fruits, obvious top advantages, easy to die after fruiting, and the fruiting parts are moved outward, and the differentiation of flower buds is achieved by pruning techniques and water and fertilizer supply.

After the walnut tree is peeled, it seems that it temporarily blocks the downward transmission of organic matter and promotes the differentiation of flower buds, but in fact, it is not guided by the situation, which violates the physiological habits of the walnut tree, and is just a flash in the pan and finally fails. The comprehensive management model of walnuts in China Agricultural Le Science advocates not moving shearing in summer, let alone ring peeling. Moreover, the fruit needs a very large nutrient supply in the expansion period, hard core period, oil injection period, etc., and it is far from enough to block the nutrient ** fruit, and the fruit produced is the fruit and the secondary fruit, which can talk about improving the quality of the fruit through ring peeling.

To improve the quality of the fruit, it is necessary to complete the judgment of the socks through the large amount of nutrients transmitted by the huge root system and the continuous photosynthesis of the green leaves.

To sum up the above, walnut trees resolutely put an end to ring stripping!

Remember: walnut trees should never be torn apart.

In fact, walnut trees do not have to be peeled, and the specific judgment method is as follows:

1) Adapt to the conditions of the tree. In fact, ring stripping is only a temporary measure for age-appropriate non-fruiting trees, and is mostly used for temporary young trees and their auxiliary branch groups. When the fruit tree enters the normal fruiting, there is generally no need to carry out ring stripping, especially for permanent branches and weak trees, try not to use or use with caution.

2) Timely ring stripping. The time requirements for ring stripping are strict and cannot be arbitrary, otherwise it will be counterproductive. The time of ring stripping varies according to the purpose, in order to promote the differentiation of flower buds, it can be carried out during the vigorous growth period of new shoots; In order to improve the fruit setting rate, it can be carried out during or before flowering; In order to control the growth, it can be done before germination.

3) The location should be appropriate. In general, temporary trees or branches should be torn off at the base; Permanent branches should be torn off at a distance of 20 cm from the base of the branches. Some trees, such as jujube trees, should be annually stripped from the base of the trunk year by year (commonly known as open armor).

4) Ring stripping should be moderate. When peeling the ring of fruit trees, it should be wide and narrow, and the depth should be moderate, and the peeling mouth should be too wide, which should not be healed, resulting in dead branches; If the peel is too deep, the branches are easy to be blown off by the wind; The stripping is too narrow to achieve the purpose of ring stripping. The appropriate width of ring stripping is generally 1 10 of the thickness of the ring stripping branch, and the erect wang branch can be appropriately widened, the general width is about 5 cm, and it is best to heal in 20 30 days, and the moderation of ring stripping is best not to hurt the xylem.

5) Post-peeling treatment. After ring stripping, timely care and other auxiliary measures should be taken. The ring peeling can be wrapped with plastic film or coated with carbendazim, tobuzin, stone sulfur mixture and other agents to prevent disease and waterproof to ensure the healing of the peel; Urea and potassium dihydrogen phosphate should be sprayed once once in the whole tree 7 days after the ring peeling, and sprayed again after 10 days to prevent the leaf color from turning yellow and falling off.

Spray fertilizer immediately.

It is recommended that you use Kao No. 2 instead of ring stripping to promote flower bud differentiation, and at the same time spray strong fruit tilling to thicken the fruit pedicle before walnut tree flowering, young fruit stage, and fruit expansion period to improve nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits.

What is Ring Stripping? I don't understand this.

Walnut trees can be circumcised twice from late May to late June, and after circumcision, the mother of flowers is coated with the mother of flowers.
