Zanthoxylum pepper tree frost damage is serious, how to recover the loss?

When frost damage occurs, it is necessary to irrigate or spray growth regulators in time to ensure sufficient water in the early stage, replenish nutrients, and ensure the recovery of tree potential. Before and after germination, the treetops that have died by frost should be cut off, and the wound should be coated with a protective agent in time after cutting to reduce the evaporation of water, prevent the invasion of diseases and insects, and enhance the stress resistance of the tree.

First of all, we can prepare some white film to cover the pepper tree, and then fertilize, many times we also have to loosen the roots of the pepper tree, and then water, and also pay attention to give the pepper tree enough sunlight.

In spring, the pruning amount of pepper trees is not large, and after being frozen, make a supplementary pruning. Because pruning a part of the branches to ensure that the above-ground parts can get nutrients to grow. After pruning, the nutrients up and down are coordinated to grow robust again. After pruning, the mixed buds are encouraged to germinate and bear fruit.

Rot can be used in April when the pathogen begins to infect, with 15% powder rust rather wet powder 300 800 times liquid or root rot net 250 times liquid irrigation of adult trees, can effectively avoid the occurrence of disease. In the diseased Zanthoxylum plantation, remove the diseased and dead plants and roots, and destroy them in a centralized manner to reduce the accumulation of pathogenic bacteria in the Zanthoxylum pepper orchard. 2.

Rust At the beginning of June, spray 1 1 100 Bordeaux liquid to prevent the occurrence of the disease. For the plants that have been diseased, 1 2 200 Bordeaux liquid, 1000 times of 15% powder rust wettable powder, 400 500 times of 65% mancozeb wettable powder, etc. In late autumn, after the leaves are harvested, the diseased branches are pruned, the fallen leaves are cleaned, and the cover is treated intensively to reduce the germs.

3.Brown spot disease is sprayed with 50% mancozeb wettable powder 500-800 times, 509% methyl tobuzine wettable powder 500-800 times or 509% carbendazim wettable powder 600-800 times. Starting from the second sentence of May, spray once every 10-15 days, 3-4 times in a row, and then once before and after the beginning of autumn, the disease prevention effect is better.

Paula: Seize the moment, bai

The pepper orchard was covered with plastic film, the trunk was painted white, and the foliar fertilizer of golden hair fertilizer or potassium dihydrogen phosphate was sprayed to protect the body of the pepper tree. Spray "flower bud antifreeze". Resist; Enhance cold resistance.

Do a good job in the fertilizer and water management of pepper orchards in early spring, apply more compound fertilizer and trace element fertilizer, do a good job in spring compound pruning, improve the quality of branches and buds, enhance tree nutrients, and improve tree cold resistance. Prevention: smoke and frost damage, pest and disease control.

Pay close attention to weather changes, pile firewood and grass in the tree rows before frost damage occurs, smoke it, raise the temperature of the pepper orchard, and form a smoke-like protective net; Identify the flow gum and do a good job in the prevention and control of pests and diseases such as pepper and scale insects as soon as possible. Supplement: Post-disaster remediation.

After the pepper tree is frozen, it should be remedied in time, and the fruit setting rate should be improved and the tree should be restored as soon as possible by cleaning up the damaged pepper branches (trees), artificial pollination, foliar spraying of sugar or honey, boron and other measures. Qing: For the tree that has died of freezing, when the lower part of the tree sprouts again, the dead part on it is sawed off, the wound is smoothed, and the seal is sealed with sealing and cutting oil or fruit rot kang to reduce nutrient consumption, promote the healthy growth of new branches, and fill the void to take the yield; Remove weeds in pepper orchards to minimize frost damage losses.

Summary. Dry rot.

In recent years, the bark of the main trunk has dried up and the bark has been warped, which is dry rot. If the bark of the branches is all dried up and cocked, the tree will die. As for how to prevent and control, for the time being, I have no experience to share, if any friend has, you can share it, thank you!

Zanthoxylum pepper trunk rot.

Sawworm (borborer) disease.

This kind of disease is a kind of insect pest, which eats wood, this insect looks like maggots, burrows into the main trunk wood of Zanthoxylum, and the external gelatin, the degree of harm is serious, and it will cause the death of the tree.

How to prevent the pepper tree from dying suddenly after it bears fruit?

Hello, I'm sorting out the answer to your question, so please wait a minute

The pepper tree bears fruit and dies, which may be caused by two reasons. 1. Caused by watering too much water. Because watering too much water will make the roots of the pepper tree unable to breathe, thus suffocating to death.

2. Watered too much fertilizer. The roots of the pepper tree are burned, which causes the tree to die. If it is a water-soluble fertilizer for fertile, it only needs to be used after dilution according to the normal dilution factor.

3. The impact of pests and diseases, especially red spiders and scale insects.

Can you look at this?

Can it solve your problem?

The peppercorn leaves were still green and died suddenly.

If you cut off the dead ones, the bottom is still good, if you don't cut them off, the whole pepper tree will die, what is the reason.

Then this should be the insect infestation.

Underground pests are caused by the death of young pepper trees.

The tree is good, only three years old.

Dry rot. In recent years, the bark of the main trunk has dried up and the bark has been warped, which is dry rot. If the bark of the branches is all dried up and cocked, the tree will die.

As for how to prevent and control, for the time being, I have no experience to share, if any friend has, you can share it, thank you! Zanthoxylum pepper trunk rot sawworm (borrower) disease. This kind of disease is a kind of insect pest, which eats wood, this insect looks like maggots, burrows into the main trunk wood of Zanthoxylum, and the external gelatin, the degree of harm is serious, and it will cause the death of the tree.

There was no change at all in the trees.

There was no flow either.

The bark is good, because I am not a specific doctor, you can not see the surface of the tree, and the leaves have not changed much, then you may need to find a relevant doctor to diagnose and treat it, this situation of your pepper tree is not common, amateurs may not be able to solve the problem, it is recommended that you find the relevant professionals to solve.

The leaves are cyan, which means that the soil has not applied too much or is not in a bad condition.

The bark is also normal, the body is healthy, and from an amateur's point of view, your tree is in a healthy state.

Yes, I just don't understand, so I suggest you go to the relevant professionals.
