Treatment of winter jujube tree madness? How to treat jujube madness

Jujube trees will inevitably have some diseases in the growth process, the common one is jujube madness, it is a very harmful disease, which will directly lead to the wilting and death of plants, so the best way to cut off the diseased parts of jujube tree madness is to cut off the diseased parts first, and then use a small amount of agricultural streptomycin solution for root irrigation, and then strengthen the circulation of air.

It is also possible to increase water and fertilizer management in the early stage of the disease, apply a thin urea solution every other week, and then loosen the soil to ensure the growth and development of the roots, and then drill a small hole in the sick part, pour tetracycline solution into the hole, and put it in a sunny environment.

Jujube tree madness, also known as "jujube broom disease", occurs to varying degrees in all parts of the province. Jujube madness is one of the most devastating of all jujube diseases. The main symptoms are as follows:

1.The flowers become leaves, the flower apparatus degenerates, and the flower stalk is lengthened.

2.The buds germinated abnormally, and the main buds of the 1-year-old branches and the hidden buds on the perennial branches of the diseased plants germinated into developing branches.

3.Leaf lesions, some leaf tips are scorched, and in severe cases, diseased leaves fall off.

4.Fruit lesions, diseased flowers generally do not bear fruit. Healthy branches on diseased plants can still bear fruit, the fruit size is different, the fruit surface is unevenly colored, convex and uneven.

5.Root lesions, due to the large germination of adventitious buds, the taproot of mad trees often grows a cluster of short mad roots, and multiple clumps of mad roots can appear on the same root.

The common ** of jujube madness is caused by the bacterium of jujube madness, which is highly infectious, and the natural vector is insects, which can also be diseased through grafting, and the incubation period of the disease is more than 25 days to more than 1 year. Jujube orchards with arid and barren soil and extensive management are seriously ill.

Second, how to make jujube tree madness**.

There are two main ways of jujube madness, but there is no guarantee of a 100% rate. The drug method is to use jujube mad No. 1, tetracycline drugs and other drugs, which can make the diseased tree produce jujube in the first year and two years. Surgery is to use physical means to completely remove the diseased branches and remove the diseased parts, and the general rate is about 85%.

When using drugs, it is generally for jujube trees with mild disease, and for jujube trees with serious disease, it is necessary to remove diseased branches and diseased plants from the orchard as soon as possible, and spray them in time to prevent the spread of pathogens. When digging out the diseased plants, the root system of the jujube tree must be cleaned to avoid regenerating diseased tillers, and at the same time, it is necessary to remove all kinds of weeds and wild shrubs in time to prevent and control various leafhopper insect vectors.

When performing surgery**, it is necessary to deal with the diseased branches and completely remove the diseased branches. Winter surgery ** jujube tree madness is the best period, to be detected early, early, on the tree and under the tree together, do not only treat the upper part of the tree, not the lower part of the tree, the handwritten ** to be thorough, clean, do not leave the aftermath.

The disease is current.

There is no effective method, and taking effective preventive measures before the occurrence of the disease in production is the best way to control the spread of jujube madness. In view of this, the following comprehensive control measures are recommended to control the development of jujube madness.

First, the diseased strains should be eradicated and thoroughly incinerated to avoid cross-infection. Second, the prevention and control of poisonous insects. Do not plant pine, cypress, mulberry, paulownia and other trees near the new jujube orchard, and do not plant cabbage and sesame crops, which can effectively reduce the number of disease-transmitting leafhoppers, and it is appropriate to control leafhoppers when the nymphs hatch and cluster on dwarf plants, and spray pyrethroids, organophosphorus and other insecticides for control.

Third, prevent the reproduction and spread of the virus. After germination and before defoliation, the branches and leaves of the jujube trees are sprayed intermittently with agricultural streptomycin, about once every two months. Please refer to the instructions for specific concentrations.

Fourth, strengthen fertilizer and water management. More organic fertilizer and phosphorus and potassium fertilizer were applied to the jujube orchard to improve the nutrition of the tree and improve the disease resistance of the jujube tree. Fifth, pay attention to the disinfection of grafting tools and pruning tools to avoid cross-infection.

It can be disinfected by burning alcohol.

Jujube madness is a viral disease of bai, which is caused by aphids and flying dukes

Lice, thrips and other pests with stinging and sucking mouthparts spread back, there is no good answer to the disease, only prevention. The main thing is to prevent and control the above-mentioned pests in a timely manner, cut off the transmission route, and once the disease occurs, it is impossible to do so. Plants with serious conditions should be cut down in time and burned outside the garden; For plants with mild disease (or no disease), foliar sprays such as virus A and phytolingling drugs to prevent and treat viral diseases are used to control the development of the disease.

Prevention and control measures:

Agricultural BAI control:

1) Clear the mad branches, eradicate the meridians.

The diseased strain of the economic value DAO.

(2) Select disease-resistant jujube varieties as rootstocks.

3) Cultivate disease-free seedlings. That is, in the jujube orchard without jujube madness, scion, budding or root splitting is used for propagation to cultivate disease-free seedlings.

4) Strengthen orchard management and increase the application of alkaline fertilizer and farmhouse fertilizer.

Chemical control: 1) In the early stage of the disease, drill holes in the rhizomes of diseased trees with a hand-cranked drill, and inject 500 ml of tetracycline solution into each diseased tree during the budding period of jujube trees in spring or in October.

2) Drill 1 hole on each side of the base or middle and lower part of the trunk without scar, deep to the medullary core, with a vertical distance of 10 20 cm between the two holes, and inject oxytetracycline solution containing 10,000 units with a high-pressure syringe. If the circumference of the trunk is more than 30 cm, 300 400 ml of medicinal solution will be used; 40 cm or more, use 500 700 ml; 50 cm or more, use 800 1000 ml; 60 cm above 1200 1500 ml.

3) At the beginning of the disease, the ferric chloride solution was sprayed 2 3 times per 667 square meters of jujube orchard, and sprayed once every 5 7 days. Each time the liquid medicine is 75 kg and 100 kg, which has a good effect on the prevention of jujube madness.

Jujube trees have jujube madness, and the most effective method should be to take both prevention and prevention at the same time

1. The introduction of seedlings and scion should be strictly quarantined to eliminate the source of infection.

2. The new jujube orchard should choose jujube madness-resistant varieties, use non-toxic seedlings, and collect non-toxic seedling scion for grafting when changing jujube trees.

3. If the diseased plants are found, including the root system, they should be completely removed and destroyed to eliminate the source of infection.

4. Do a good job in the prevention and control of leafhopper stinging and sucking mouthparts insects in time to reduce the chance of insect transmission.

5. The tools used to work on the diseased trees should be thoroughly disinfected to reduce the transmission of disease in the working tools.

6. There is information that the trees with mild disease can be completely sawed off diseased branches, trunk ring sawing, root cutting and punching and injection of drugs, etc., with a rate of more than 50%. The author still recommends that it is better to completely eradicate the diseased strain, because although the ** rate of more than 50% has been greatly improved, there is still a possibility that 50% of the infectious sources will continue to spread.

7. It is necessary to strengthen the comprehensive management of jujube orchards, increase the application of organic fertilizer, enhance the tree potential, and improve the ability of jujube trees to resist various diseases.

8. Drug prevention and control: the use of trunk punching and injection method has a good effect. First remove the diseased branches of the diseased tree from the base, and then drill 3 holes in the trunk, the plane angle between the holes is 120 ° (3 holes are evenly distributed in a circle) with a plastic bag with an infusion needle to inject medicine into the trunk hole, with oxytetracycline, tetracycline or anti-madness No. 4 and anti-madness No. 8 developed by Hebei Agricultural University, the concentration is 1%, the light disease tree is 500 grams of dropping liquid per plant, the moderately diseased tree is injected with 1000 grams, and the seriously diseased tree is injected with 1500 2000 grams, and the best period for prevention and control is the jujube tree prosperous period, and the northern jujube area is the best in late April.

Moderately and severely diseased trees should be **2 3 years in a row.

Jujube trees are most afraid of jujube madness, and there is no particularly effective method for this disease at present.

If it is lighter, you can use pruning, tetracycline injection, or root irrigation.

If the disease is more serious, it is necessary to stop the spread of the disease and dig up the whole jujube tree to avoid the source of infection.

Hello, I am honored to answer for you, jujube madness in the early stage of the disease, in the root and stem of the diseased tree drilling, in the spring jujube tree budding stage, each diseased tree instillation concentration of tetracycline solution 500 ml, or spray ferric chloride solution per mu 2-3 times, spray once every 5-7 days, each time 75-100 kg of solution. Removal of diseased plants: Cutting down diseased branches to eliminate pathogens.

Plane the roots, if there are root bacteria, kill them with glyphosate, etc. Mildly diseased trees with only small branches are cut down or ring-stripped from the base of the large branches before the sap flows back to the roots; Preventing the pathogen from running with the tree nutrients for 2-3 years can basically control the local jujube madness. Harvesting scion, grafting or splitting roots in jujube orchards without jujube madness is used for propagation to cultivate disease-free seedlings.

Use 10 million units of tetracycline to mix 300 500 ml of distilled water, inject at least 100 ml of the liquid medicine solution into the phloem of the trunk with a needle within 8 12 hours, or drill holes around the trunk to reach the xylem, stuff the cotton ball soaked in the tetracycline injection solution into the air, seal the hole with tape for a week, and then take out the cotton ball, seal the wound and heal quickly. The method is simple and effective, not only to prevent widespread infection, but also to save patients.

The cancer of the jujube tree, "jujube madness", female experts can not only cure but also prevent it, all relying on these four tricks.

Jujube contains a lot of vitamin C and vitamin P, which can be eaten fresh, or dried to make tea, make soup and other edible methods.

It has the effect of nourishing the stomach, strengthening the spleen, benefiting the blood, nourishing and strengthening the body, and the jujube kernel and the root can be used as medicine, and the jujube kernel can calm the nerves. In rural areas, it is customary to plant fruit trees around one's house or in the yard, and among the many fruit trees, the jujube tree has naturally become one of them.

The jujube tree is crazy, in fact, it is a viral disease caused by a virus carried by leafhoppers. Also known as male jujube tree, jujube tree broom disease, can harm the buds, flowers, leaves, roots, etc. of jujube trees, and its main symptoms are:

1. At this time, the symptoms of the whole plant are that the new leaves of the plant are small and yellow, showing clumpy growth, clustered together, and almost no fruit can be seen. The main reason is that the main buds and hidden buds on the jujube tree do not germinate normally, the annual development branches on the plant and the hidden buds on the perennial old branches germinate together into development branches, and the buds on the development branches germinate twigs, and the twigs germinate twigs, etc., resulting in the shortening of the branch details. In severe cases, clusters of leaves may also grow at the base of the plant.

2. The flowers of the infected jujube tree turn into leaves, the flower apparatus degenerates, the flower stalk is extended, the sepals, petals, and stamens all become leaflets, the pistil is transformed into twigs, and the whole plant only sees leaves.

3. After the leaf lesion, the whole leaf yellows, the leaf edge rolls upward, the leaf becomes hard and brittle, and the diseased leaf falls off in severe cases. The leaves that grow after the flowers are relatively narrow, emerald green, and easy to scorch.

4. The number of short roots is mainly increased, and short roots will grow in different parts of the same root system of the infected root, which is because the vegetative growth of the aboveground part of the plant is vigorous, which has to promote the underground root system to grow more roots. After 3-6 years, the cortex of these diseased roots begins to rot, and in severe cases, the plant dies.

The control method of crazy jujube tree.

The earlier the prevention and control of mad jujube disease, the better the effect, and at the same time, it is conducive to the recovery of the jujube tree. For jujube trees in the yard, don't be blinded by the phenomenon of the size of the jujube tree.

1. Drug prevention and control For the plants that have just occurred of jujube madness, dilute them with 40 grams of Zao Crazy No. 1 with 15 kg of water in the germination or flowering period of the jujube tree, and add 1 kg of pure milk at the same time, stir evenly and spray, which can easily solve the jujube madness at the beginning.

2. For plants with more serious damage, it is necessary to sawing or cutting off roots before the jujube tree falls leaves in winter or before germination in early spring. And the root system is irrigated with Boer solution or the wound is applied.

3. Clean up the fallen leaves and weeds under the fruit trees, and do not give leafhoppers a place to overwinter. Leafhopper is the main vector of jujube madness, only in winter do not create environmental conditions for leafhoppers to overwinter, try not to pile firewood and straw in the yard, prevent it from overwintering in straw and firewood, and spray insecticides in time from May to August for poisoning.

The above is the explanation and prevention methods of the jujube trees planted in the yard "crazy", and it is necessary to pay attention to the management of jujube trees and maintain the balance of fertilizer and water. Reduce the chance of jujube madness infection.

In the process of growth, if there is madness, it needs to be treated in time, mainly to cut off the branches and leaves of the diseased parts, and then use a small amount of agricultural streptomycin solution for root irrigation, which can also increase water and fertilizer management and improve soil quality, and then use the drilling method to water tetracycline solution to strengthen air circulation.

At present, it can only be prevented, not very good**. Jujube madness is a viral disease, which is mainly transmitted by aphids, planthoppers, thrips and other pests.

Small holes should be drilled in the rhizomes of jujube trees suffering from jujube madness, tetracycline solution should be injected, and the infected branches and leaves should be cut off to prevent the spread of pathogens.

The cancer of the jujube tree, "jujube madness", female experts can not only cure but also prevent it, all relying on these four tricks.

Jujube trees will inevitably have some diseases in the growth process, the common one is jujube madness, it is a very harmful disease, which will directly lead to the wilting and death of plants, so the best way to cut off the diseased parts of jujube tree madness is to cut off the diseased parts first, and then use a small amount of agricultural streptomycin solution for root irrigation, and then strengthen the circulation of air.

It is also possible to increase water and fertilizer management in the early stage of the disease, apply a thin urea solution every other week, and then loosen the soil to ensure the growth and development of the roots, and then drill a small hole in the sick part, pour tetracycline solution into the hole, and put it in a sunny environment.

1. Soil replacement treatment

Jujube trees grow well in organic soil with strong loose soil layer and deep water retention effect, and can be selected with humus soil, garden soil, peat soil, and river sand according to 3:2:2:

The ratio of 1 is mixed and prepared, and then an appropriate amount of organic fertilizer is added as a substrate when cultivating, and the soil is changed every 1 2 years to promote the growth and development of roots.

2. Environmental requirements

Because jujube trees like to grow in a warm and well-lit environment, it is best to ensure that there are 5 to 6 hours of light time every day, control the temperature at about 15 25, and strengthen air circulation in the summer high temperature season, and place it indoors in a sunny place in the cold season in winter.

3. Water and fertilizer management

The growth of jujube trees does not have very high requirements for water, generally keep the potting soil moist, maintain the watering principle of seeing dry and wet, and then water enough water before winter, but also timely loosen soil weeding treatment, add urea solution every 1 month, and strengthen the circulation of air.

4. Reasonable pruning

The growth of jujube trees is inseparable from reasonable pruning treatment, generally in winter and summer pruning is the best, mainly the years of robust branches for shrinking and pruning, and then the longer branches to be cut short, but also to remove the top buds in time, pruning the branches on the branches too dense branches, dead branches, rotten branches, etc., to ensure the flowering and fruiting of jujube trees.
