What are the symptoms of rotten roots in fruit trees? What are the causes and how can they be preven

First of all, let's talk about the symptoms of rotten roots, the manifestation of rotten roots of fruit trees is that the tree is weak, no or less strips, thin and short, and the leaves are small and light. The leaves begin to turn red early in autumn, and these symptoms can basically be concluded as having begun to rot or have rotted roots. There are many causes of root rot, which should be viewed from many aspects, such as root burning caused by improper fertilization, and weather reasons such as drought and water loss for too long.

Caused by continuous rain or other causes of waterlogging of the roots of the tree. Excessive soil acidity and alkalinity can also cause root rot. Therefore, effective measures should be taken to solve the above reasons.

If it is caused by improper fertilization, it should be watered more to dilute and cool. If it is due to the weather, it should be watered or drained in time, and at the same time, it should be solved by hoeing and ventilation. If the soil pH is too high, the pH value of the soil should be adjusted.

All of the above causes must be addressed by rooting. In addition, when pruning in winter, it should be re-cut and leave more strips. Properly prune some flower buds and branches, especially the weak string flower branches and drooping branches, and extend the branches to restore the tree momentum by breaking the head.

If it is a rotten root caused by a germ. Methods of medicated root irrigation and biological root rearing should also be used. Such a multi-pronged approach can still be solved.

Of course, if the roots are rotten, you can only replant small trees!

Rotten roots of fruit trees can be considered from three aspects: 1Fertilizer burns the roots. 2.The soil is long-term watery and rooted. 3.Pathological root rot, such as root rot. It should be judged on a case-by-case basis.

Fruit tree root rot performance, fruit tree root rot root nutrients ** insufficient leaves yellow, even leaf shedding, slight fruit tree hanging fruit. The fruit growth is stunted and the fruit is small. Poor taste and texture. Poor quality. The yield is low and the disease is severe. The whole tree died.

There are many reasons for root rot of fruit trees, and the long-term application of chemical fertilizers neglects the application of well-rotted organic fertilizers, resulting in low soil organic matter content, soil compaction, soil acidification, etc., and various soil pathogens.

problems, causing rotten roots of fruit trees, etc.

Comprehensive control measures, fruit trees generally grow in the range of 20 80 cm deep under the surface, the root system grows in a depth of about 35 50 cm, and the application of rotten organic fertilizer should be applied to the ditch and the ground.

<> dig 40 50 cm downward, shallow ditch is not conducive to fertilizer absorption, reduce root resistance, drought resistance, waterlogging resistance, root preservation, it is not recommended to use unrotted farm fertilizer, so as not to cause various germs. and burnt roots. Only when fruit trees are fertilized properly will they have a better root system, and a good root system can absorb more nutrients and provide poles for the ground.

Branches. Leaf. Waterlogging in an orchard can lead to roots.

Rotten, well drained in the orchard.

Rotten roots of fruit trees are mainly made of compost.

Root rot or other improper management, the initial symptoms are strong mainly manifested in the leaves greening, small and yellow leaves, underdeveloped branches and buds, when the disease is serious, it will cause the branches and leaves to dry up until death, the specific reasons are as follows.

1. Rooting: Mainly due to low soil temperature, too many times of watering, or too much watering in the case of low temperature on rainy days, insufficient light, resulting in long-term low temperature and too wet root system, due to the phenomenon of root rot caused by covering fertilizer, resulting in stunted plant development, small leaves and loss of green, and the whole plant dies in serious cases, so management should be strengthened in production, appropriate control of moisture, prevention of over-drying and over-wetting, do a good job of drainage measures, strengthen cultivation, increase soil temperature, reduce humidity, and avoid rooting.

2. Root rot: This disease is a soil-borne disease, which generally occurs in April to June, and the disease is the most serious in June and August, the main pathogen is Fusarium saprophyticus, and the root of the diseased plant is the root bark and xylem.

Separation, the xylem is blackened, the aboveground leaves become smaller, and the leaves lose green, and when the damage is serious, the whole plant dies.

Therefore, the management should be strengthened in production, pay attention to the planting density, deep soil turning and disinfection, maintain soil aeration capacity, timely and appropriate control of watering and fertilization, find diseased plants, catch out the diseased roots and destroy them in a centralized manner, reduce the accumulation of pathogenic bacteria, in April when the pathogenic bacteria first appeared, 65% dextrose manganese zinc 600 times, or 50% methyl tobuzin can be used for adult trees.

1000 times, or 250 times root rot net irrigation, can effectively avoid the disease.

Fruit trees will rot their roots, which is a relatively common disease condition in the process of fruit tree cultivation. Most of the rotten roots are difficult to detect in the early stage, and only when this situation reaches the upper part of the ground will it be gradually discovered, and then some topdressing or spraying measures are not very effective. Therefore, when you notice that the growth process of fruit trees is relatively slow, and the leaves are very small and yellow, you should be aware of it.

In the process of planting fruit trees, it is necessary to be careful not to use excessive chemical fertilizers, nor to overuse them, and the farmyard fertilizers that have not been fermented will cause rotten roots and dead trees. <>

1. What are the symptoms of rotten roots of fruit trees?

First of all, you can observe the fallen leaves of fruit trees, the leaves of rotten fruit trees will become yellow and yellow, and the branches of fruit trees are very easy to break, and the whole tree looks relatively dry. Secondly, observe the growth rate of the fruit tree, if there is rotten roots, the growth will become very slow, and the germination will be later than other normal fruit trees, and the leaves of the fruit tree will be scorched and yellowed. You can also dig up the roots of fruit trees to find that the rotten roots will turn dead brown and uneven, and even some cortices will show ulcers, and you can also press out some dark brown leaves and branches with your fingers, accompanied by a peculiar smell.

2. What should I pay attention to?

In the process of planting fruit trees, organic fertilizers should be used to reduce the use of chemical fertilizers. Organic fertilizer not only improves the soil, but also promotes the growth of the root system of fruit trees, as long as the root system grows vigorously to produce new roots, then the root rot will be reduced. Chemical fertilizers must not be used for a long time, because it will lead to the lack of organic matter in the soil so that harmful bacteria can multiply again, and the beneficial bacteria will not have the environment to survive, and at the same time, chemical fertilizers will also cause the branches of fruit trees to only grow branches, but the results are not much.

At the same time, in the growth process of fruit trees, it is necessary to strengthen management, spray measures to protect leaves, top dressing in summer, consolidate fertilizer in autumn, and finally manage in place to make the nutrient storage in fruit trees sufficient. Insufficient nutrients stored in fruit trees can also lead to severe root rot in fruit trees.

The growth of surgery is slow, the branches and leaves are yellow, and there will be a large number of branches and leaves, the flowering period is short, and the branches of fruit trees show serious wilting, and the yield is reduced. It should be noted that when this situation occurs, it is necessary to choose the first time in time, spray pesticides and nutrients in time, and strengthen soil management and use farm fertilizer.

It may cause the leaves to fall off, grow slowly, and may also cause the leaves to turn yellow, and some trees have necrotic spots on the edge of the leaves; It is necessary to pay attention to field management, effectively maintain low temperature balance, improve soil environmental structure, enhance air permeability, reasonable fertilization and drainage, improve soil environment, and reasonably use effective fungicidal pesticides for root irrigation.

It will be manifested as the beginning of vertical weakness, no or few strips, the strips drawn out are thin and short, and the leaves are small and light-colored; But there are many causes of roots, which can be caused by looking at many aspects, such as the weather causes of the upper jaw caused by improper fertilization.

There are many reasons for root rot in fruit trees, and if deep ploughing is not carried out for a long time, it will affect the normal growth of fruit trees. Therefore, everyone must go to the orchard regularly to deal with it, so as to prevent this problem from coming to the door. If too much organic fertilizer is applied during the planting process, or too little organic fertilizer is applied, then the fruit tree will be deprived of nutrients as it grows.

When planting fruit trees, it is necessary to choose soil with good air permeability, which can prevent the growth of some anaerobic bacteria. We need to keep ventilation and apply organic fertilizer during the planting process, because organic fertilizer can improve the soil conditions, effectively help the root system grow, and allow fruit trees to grow new roots. But when applying organic fertilizer, you should also pay attention to the amount at home, and never apply too much.

You also need to dig up the roots, you can dig out some diseased roots first, and then put these roots outside. Regular treatment can have a certain effect on eliminating germs. <>

In the process of growing up, I found that everyone knows how to water, but we must pay attention to science and reasonableness. If it is after rain or after watering, it is necessary to carry out tillage at this time, because this can dredge the soil, and at the same time, when watering, you must water according to the rows, not too close to the main trunk, otherwise it will affect the growth of fruit trees. You can prune the root system, you can use a ditching method, so as not to affect the growth of other root systems.

For fruit growers, the last thing they want is to see rotten roots happen to them. We must prescribe the right medicine, so that we can achieve better prevention and treatment results. At the same time, since you have chosen to become a fruit farmer, you need to be more diligent, you must do a good job in daily management, and don't choose to be lazy.

Otherwise, it will affect the harvest of fruit trees and directly affect everyone's income. Deal with problems in a timely manner.

It may be because the soil humidity is very high, there is a lack of some fertilizer or there is a lot of fertilizer, and the ventilation is not particularly good, which can easily cause root rot. At this time, we should pay attention to drainage, there should be a very good fertilization, proper pruning of some branches, and the use of some drugs to kill pests and diseases, so that it can be well controlled.

Reasons: 1. Long-term chemical fertilizers are in charge, and fruit trees are the first to suffer. 2. A large amount of unfermented and rotted farmhouse manure is applied, resulting in rotten roots and dead trees.

Prevention and control methods: 1. Change the awareness of fertilization and get out of the misunderstanding of chemical fertilizer. Promote the use of farm fertilizers.

2. Improve fertilization methods and strengthen soil management.

Rotten roots of fruits and vegetables may be caused by the lack of chemical fertilizers, resulting in the destruction of soil acidity and alkalinity, and the root system of the soil being attacked by fungi; First of all, it is necessary to change the acidity and alkalinity of the soil in time and choose the right fertilizer.

Anyone who grows fruit trees knows that in April and May every year, there will be a disease on the branches of various fruit trees, that is, the leaves of the main branches, branches, auxiliary branches and other leaves suddenly wither, as if scalded by hot water, so do you know what is going on? In fact, this is also a manifestation of rotten roots of fruit trees, let's take a look at them together. Fruit tree rotten rootsFruit tree rotten root manifestation symptoms from the roots, where the main branch on the ground is diseased, the root corresponding to the main branch in the ground will rot the roots.

After rotting the roots, the root bark is dark brown, and the root bark and the wooden part are removed.

Fruit trees are caused by rotten roots

The plantation has not been subsoiled for a long time, the soil type is not good, and the soil environmental humidity is too high. Too little or too much organic fertilizer can cause fruit trees to lack nutrients, grow poorly, or be scalded by chemical fertilizers. The soil is heavy and compacted, the gap is small, the ventilation is not good, and the root system cannot grow normally, which leads to the resource advantage of life development and growth of the root rot fungus.

The rot of the root system of fruit trees will cause the decline of the plant shape, which will lead to other physiological pests and diseases, so it is necessary to strengthen management and pay attention to prevention.

Ways to prevent root rot in fruit trees

Planing the roots and drying the roots. If the root rot caused by brown spot disease is attributed to the fungus, it will be touched by gas and the use of solar ultraviolet light, which can play a role in inhibiting the breeding of germs and eliminating germs.

Pay attention to the top application of organic fertilizer: Organic fertilizer has the effect of improving the soil and promoting the growth of the root system. As long as the root system is full of vitality and can continue to grow and renew the roots, the disease of root rot will be alleviated.

It can also be used to irrigate roots with biological agents, such as Bacillus subtilis, Brassin and immediately replenish a variety of nutrients, which has the effect of inhibiting the growth of pathogens and promoting root growth.

Autumn bottom fertilizer: try to choose the method of ditching and fertilizing row by row, and ditching can break the root system a lot, which is equivalent to pruning the root system. Broken roots grow a lot during the peak hair season in autumn, which is similar to the mechanism of upgrading and pruning old trees.

4. Scientific research and irrigation: especially loclay plantations, saline soil compaction soil plantations, after the summer rain or irrigation, it is easy to make the soil compact, so after every rain and watering, carry out soil cultivation to loosen the soil. When it is indeed necessary to sprinkle water, it should only be watered in rows and rows, and the position close to the main pole should not be watered as much as possible, so as to facilitate the aeration of the soil and meet the requirements of aerobic respiration of the root system.

Scientific irrigation: especially in yellow clay plantations and saline soil compaction soil plantations, it is easy to make the soil compacted after the rain or irrigation in summer, so after every rain and after watering, soil cultivation is carried out to loosen the soil. When it is indeed necessary to sprinkle water, it should only be watered and rowed, and the position close to the main pole should not be watered as much as possible, so as to facilitate soil ventilation and meet the requirements of aerobic respiration of the root system.

Drug prevention: Under the diseased tree, dig a circular ditch and irrigate the roots with medicine. The prevention method of rotten roots of fruit trees is the explanation of rotten roots of fruit trees, whether it is apples, apricot trees, fruit trees, etc., all of them will have the problem of rotten roots, so everyone's daily management methods or to achieve countermeasures to prevent rotten roots.
