Yellow leaves of the pepper tree and withered leaves? How to treat the wilting branches of the peppe

1. Zanthoxylum pepper trees lack fertilizer. Although the pepper tree is drought-tolerant, barren and cold-tolerant, it still prefers deep, fertile and loose sandy loam soil. Zanthoxylum pepper generally enters the budding period in mid-April, and can mature and harvest fruit in late July, in the middle of the green pepper is the need for fertilizer to grow the fruit, while growing the fruit while growing the branches and leaves, the root system absorbs nutrients, most of them are allocated to the fruit, the nutrition of the leaves is relatively reduced, so the leaves appear yellowing, especially the nitrogen deficiency of the pepper tree is more obvious.

Therefore, in order to achieve high yield, it is necessary to apply sufficient fertilizer in time. Therefore, during the flowering and fruit-setting period of Zanthoxylum bungeanum flowers, 40 kg of 45% controlled-release fertilizer was applied per mu, and watering was carried out to protect moisture, so that the pepper trees could grow healthily.

2. The pepper tree was damaged. Zanthoxylum bungeanum trees are cold-tolerant, drought-resistant, but not waterlogged, if the pepper trees are damaged for a long time, the leaves will be yellowed, the growth potential will be significantly reduced, and the heavy will appear dead. Therefore, during the growth of the pepper tree, if there is waterlogging, it should be drained in time to prevent the symptoms of damage due to poor breathing of the root system of the pepper tree.

3. Zanthoxylum pepper trees have root rot. After the pepper tree is waterlogged, root rot is most likely to be caused. In particular, some pepper trees are older and more susceptible to disease.

Therefore, before it is not damaged, the roots are irrigated with pesticides to help the pepper tree improve its disease resistance.

4. Zanthoxylum pepper yellow leaf disease is also called nutrient deficiency. It occurs mainly in calcareous soils and saline soils. It is a mosaic disease caused by iron deficiency of peppercorns.

Such soil is mainly to increase the application of organic fertilizer, so as not to make the soil overly arid and reduce the salt content of the soil. Soil conditioner can be appropriately selected to condition the soil, while applying organic fertilizer, each plant is mixed with 500 grams of ferrous sulfate, foliar spraying in advance during the growth period, and foliar fertilizer containing iron Brassinolide is prevented. Pay attention to scientific irrigation, and use water to suppress the alkali upward.

Planting in the heavier plots of saline-alkali land can be selected, and the disease-resistant rootstocks that are more tolerant to salt and alkali can be grafted to improve the disease resistance. For the more serious disease of Zanthoxylum bungeanum trees, they should be re-pruned or replaced in time.

5. Pests. Zanthoxylum jidin can cause damage to the main trunk of Zanthoxylum bungeanum pepper, the main pillar stone of Zanthoxylum jidin, the cambium layer in the bark of Zanthoxylum bungeanum tree, and the serious damage can make the nutrient transport of Zanthoxylum bungeanum from the root upwards to be blocked, and the yellowing of the leaves of Zanthoxylum bungeanum tree appears. It also often causes the occurrence of gum disease in pepper trees, and even the death of branches and crowns.

In addition, the red spider of the pepper tree is seriously harmed, and it often causes the yellowing and greening of the leaves of the pepper tree, especially in the dry season, the red spider is easy to break out, therefore, special attention should be paid to the observation, when there are red spiders sporadically occurring, you can use acaricides such as Dadiling or spirodifen to spray and control in time.

Yellow pepper yellow leaves and fallen leaves are red, and people teach yellow leaves and fallen leaves to sockeye salmon.

The trunk of the pepper tree is mostly infected with dry rot.

This kind of disease will mainly be concentrated in the main branches, trunks and branches, and the diseased parts will rot and dry up, seriously affecting the normal growth and development.

If this disease is found, it should be pruned in time and the diseased branches should be cut off to avoid further infection. It is also necessary to pay attention to the adjustment of management methods, and timely topdressing treatment during the growing season to enhance its disease resistance. In addition, it is necessary to pay attention to insect pests and spray drugs in a timely manner.

Zanthoxylum pepper maintenance method:

1. Soil selection. It is best to choose fertile and deep sandy soil for planting pepper trees, and after choosing the soil, you can use an appropriate amount of farm fertilizer, urea, superphosphate, etc., after fertilization, you need to turn it over, and after a few days, the soil will be flattened and weeds will be removed.

2. Selection and seedling breeding.

The seeds of the pepper tree have good waterproof power and need to be treated to absorb water and germinate. The specific method is to soak the seeds with a concentration of 1% washing, and after four hours, the seeds can be deoiled and then washed with water and mixed with plant ash for sowing. Or you can put the seeds directly in warm water containing plant ash, add sand and rub them by hand until the seeds are gray and have no luster.

3. Planting. The next step is to sow the seeds, now dig a hole about 3 cm deep in the pot and put the seeds in. If there are too many seeds, dig a little deeper. After putting it in, it should be watered first, and the water needs to ensure that the pit is moist enough before it can be covered with soil.

After the soil is ready, water it again, and in winter, you need to wait until the next year to remove the seeds and put them in a warm place for germination.

4. Pruning and maintenance.

After the plant germinates and grows, especially after the branches and leaves are luxuriant, it is necessary to prune, proper pruning can make the light sufficient, good ventilation, so as to promote the growth of pepper, but also pay attention to the prevention and control of pests and diseases.

1. The main reason for the wilting of pepper leaves is: water yellow. Caused by over-frequent watering, it is characterized by no obvious change in the old leaves and yellowing of the young leaves.

2. Dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, and if the lack of water is a little longer, the whole plant will be yellow and even die.

3. Fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny and uneven young leaves.

4. Hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole yellow leaves or even die.

5. In order to prevent the wilting of Zanthoxylum zanthoxylum, or find that the leaves of Zanthoxylum bungeanum are wilted, field management should be strengthened: reasonable pruning: Zanthoxylum zanthoxylum tree pruning is mainly based on winter scissors, supplemented by summer shears.

Summer pruning is to adjust the angle of the branches by pulling, pressing, falling and other methods to improve the light transmittance inside the canopy. At the same time, topping is carried out on side branches with a length greater than 50 cm to promote flowering and fruiting. Winter pruning is mainly used to remove diseased and insect branches, weak branches, overly dense branches, cross branches and long branches, etc., so as to improve the internal environment of the canopy and prevent the fruiting parts from moving outward.

Fertilization management: Zanthoxylum fertilization is mainly divided into basal fertilizer and top dressing. The function of basal fertilizer is to promote the differentiation of flower buds of Zanthoxylum bungeanum trees, improve leaf photosynthesis, restore tree potential, and lay the foundation for high yield of Zanthoxylum bungeanum in the following year.

The base fertilizer is mainly organic fertilizer, generally after clearing the garden in autumn, open a 40 cm deep ditch at the drip line of the crown, according to the young tree to apply organic fertilizer kilograms, superphosphate kilograms, adult trees apply organic fertilizer kilograms, superphosphate kilograms of dosage into the ditch, and then cover the soil. Top dressing is generally carried out in the fruit expansion period, according to the amount of topdressing gram urea and kilogram of superphosphate per plant, which can not only effectively promote the growth of new shoots, but also improve the fruit setting rate and promote the growth of fruit ears.

6. Water management: The water management of Zanthoxylum bungeanum is mainly divided into four main periods: frozen water, germination water, post-flower water and pre-autumn water. The frozen water is watered once in winter when the pepper is dormant, which can meet the water demand of the plants during the dormant period and alleviate the occurrence of frost damage.

Budding water is generally watered in March, and it is advisable to irrigate with small water to avoid lowering the ground temperature. Watering after flowering at the fruit-setting stage can effectively promote the increase of yield and income of Zanthoxylum zanthoxylum. Pre-autumn watering is done after the fruit is harvested to encourage the tree to store energy.

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.

Soil waterlogging: During the growth period of the pepper tree, it is overwatered, which causes the roots to breathe poorly, resulting in leaf loss. Environmental discomfort:

If the breeding environment is too dark or exposed to strong light, the plants will wilt. Lack of fertilizer: insufficient fertilization, lack of potassium fertilizer, phosphate fertilizer, etc., pepper will also lose leaves.

Infected diseases: After being eroded by pests, a large number of leaves are lost.

1. Soil waterlogging

Zanthoxylum pepper tree is more drought tolerant, but can not tolerate waterlogging, once watered too much, it will lead to water accumulation in the soil, so that the roots are suffocated and difficult to breathe normally, and the absorption becomes poor, unable to absorb sufficient nutrients to supply the leaves, resulting in yellow leaves and leaf loss.

2. The environment is uncomfortable

During the growth and maintenance of the pepper tree, light problems will also affect the leaves, resulting in leaf fall, if the environment is too dark or strong light exposure, the leaves will grow poorly, and in serious cases, they will all fall off.

3. Lack of fertilizer

During the maintenance and management period, if the fertilization is insufficient, the lack of potassium or phosphorus fertilizer will cause the color of the young leaves of the pepper tree to become lighter, the leaves will appear yellow or light green, and the old leaves will gradually fall off.

4. Infection with diseases

After the pepper tree is eroded by pests, there will also be defoliation, common insect pests are aphids, scale insects, etc., after the eggs are found, they should be sprayed with dimethoate 500 times in time, and do a good job of cleaning up the countryside, remove yellow leaves, fallen leaves, dead leaves.

AbstractThe yellowing of the leaves of Zanthoxylum bungeanum tree may be caused by waterlogging in the soil, so it is necessary to control the watering and loosen the surrounding soil to promote the water outflow, seepage and evaporation. It may also be caused by a lack of fertilizer, and regular topdressing should be carried out, and trace elements should be applied in a targeted manner. It can also be caused by improper lighting, so you can give reasonable sun exposure and shade it during bright light in summer.

Or it may be caused by infection with pests and diseases, and spraying is required**.

What is the disease of yellowing the leaves of the pepper tree.

Dear I am working on the answer to this question, please be patient.

The yellowing of the leaves of the pepper tree may be caused by waterlogging in the soil, so it is necessary to control the watering and loosen the surrounding soil to promote the water outflow, seepage and evaporation. It may also be caused by a lack of fertilizer, and regular topdressing should be carried out, and trace elements should be applied in a targeted manner. It can also be caused by improper lighting, so you can give reasonable sun exposure and shade it during bright light in summer.
