What is the best way to deal with rotten roots of a big tree?

1. Plant root rot will have a great impact on the growth of plants, if the root rot has occurred, the plant roots should be sterilized in time, the root rot must be treated thoroughly, can not leave residues, clean up and then clean and dry and put it in the sterilized pot.

2. Plant root rot is focused on prevention, and it is necessary to protect more often, understand the habits of plants, give suitable growth conditions, and sterilize flower pots in time.

Generally, the roots of the trees need to rot firstClean up the rotten parts and keep themThe disease does not continue to be transmitted againSterilization and disinfection of tree cavities using allicin and resurrection. This is because rot germs can remain in the soil for a longer period of time and continue to infect other good roots.

Rotten roots can be seen in daily maintenance. The main manifestations are stunted tree leaves, yellowing, drooping, and no longer fresh. It is important to detect the condition of the tree in time so that it can be dealt with in time.

If you wait until the growth of the tree has decreased significantly, and the disease is more serious, it is relatively difficult because the disease is deep.

Method

(1) Ditching blockade:

When the diseased plants are first seen or there are few diseased plants, immediately open a deep ditch under the drip line around the diseased plants to block, and irrigate the roots to prevent the diseased roots from coming into contact with the healthy roots of the surrounding trees and prevent the spread of the disease.

(2) Root cleaning and disinfection:

Dig the soil of the tree tray and inspect it, cut off the rotten roots, scrape the rotten cortex and wood of the diseased part, and pick it up and transport it out for centralized burning. Spraying sulfur powder evenly on wounds and roots can control root rot and promote new roots.

When the roots of the tree are yellowed, the root soil should be cut and the roots should be sheared, and sulfur powder should be sprinkled on the roots to cover the fresh sterile soil to prevent the root rot from continuing to occur.

(3) Replace the root by grafting:

If the big root rots a lot, after doing a good job of root cleaning and disinfection, plant three rootstock seedlings with developed root system and strong growth in a triangular shape next to the main trunk, and connect them to the main trunk after survival, and replace the function of the old roots with the root system of the new rootstock, so as to save the dying plants and promote the recovery of tree potential.

(4) Medicinal fertilizer**:

The more thorough way to control root diseases in deep-rooted plants is to irrigate the roots of the liquid tree tray.

Method: The topsoil of the diseased tree tray is first opened to dry the roots, and then the tree tray is watered with medicinal solution, and the entire root zone is soaked with the medicinal solution.

After the root rot of large trees, the root system is relatively weak and the nutrient absorption is poor, so it can be maintained with the help of Happy Forest Rooting Powder to promote the germination of new roots and improve the root function.

As long as the roots of the tree rot for a long time, there will be poor nutrient absorption, resulting in a lack of nutrients in the tree body, which can be supplemented with nutrients through foliar fertilizer and nutrient solution of large trees in the happy forest to improve growth.

After soil disinfection, it is temporarily in a sterile state, which is easy to create conditions for the invasion of harmful bacteria, so after half a month of soil treatment, it is necessary to supplement biological fertilizer in time to maintain the dominance of beneficial bacteria in the soil, so as to inhibit the flood of harmful bacteria.

Trees with too many flowers and fruits should be thinned with flowers and fruits, and carefully cultivated to protect the root system and root neck from damage, so as to reduce the invasion of pathogens and enhance disease resistance.

Trees with many underground pests such as black locust and grubs should not be planted around, and poisonous bait should be sprinkled in the soil during the occurrence period. In late autumn and early spring, the trunk is painted white to prevent frost damage caused by the large temperature difference between day and night.

The soil at the roots can be dug up to allow the remaining roots to be fully exposed to the air.

You can pile up rotten leaves, trees, and branches, that is, those that have turned brown in color, and crumble at the touch of them, and spray them with water, and cover them with plastic sheets.

The sulfuric acid solution can be poured directly. You can use the mother liquor of the tree protector to irrigate the roots, prevent and control airborne diseases, disinfect the plants, gently scratch the trunk with a blade on the diseased skin, and apply the mother liquor of the tree protector with a brush, which can dry up and fall off the diseased skin.

Usage:

First of all, you can use rotten wood as a pot to grow succulent plants. Although the rotten wood is a little broken, it is also very good to use as a flower pot.

Then there is the idea of making a work of art from rotten wood and hanging it on the wall, which is also a different kind of scenery, which is perfect for those who love art.

The second is to polish the rotten wood into such a light holder. The light stock is made of wood, and the candle is combined with the light stock made of rotten wood, so that it looks more coordinated.

Then let the rotten wood grow some moss and some small plants directly, so that it can also be used as decorations, and it looks extremely good.

Then there's the art that can be used to make a large animal series. Of course, not just elephants, but also many animals.

A large amount of nitrogen fertilizer can be used, and it is bioticHerbicidesand almsgivingQuicklimeand other alkaline substances.

Buried large amounts of nitrogen fertilizer。Applying a large amount of nitrogen fertilizer can burn the roots of the plant, and the roots of the tree are already completely rotten, and the soil moisture content of the roots will be greatly reduced after fertilization, and after about 7 to 10 days, the roots will rot.

A large amount of herbicide can be applied。Herbicides themselves are alkaline or acidic, and they are very corrosive, especially high concentrations of herbicides, which have a very obvious corrosive effect on the roots of trees, so a large number of herbicides can be applied to corrode the roots of plants.

Apply a large amount of alkaline substances such as quicklime。The main chemical component of quicklime is calcium oxide.

After applying quicklime, it can react with water, and a large amount of heat will be generated during the reaction, which will directly burn the roots of the tree completely.

Precautions for the use of medications:

It is necessary to grasp the area of approved pesticide application, and then calculate the dosage and application solution according to the recommended dosage of pesticide label or the recommendation of plant protection technicians. Be sure to operate in a sheltered place, and use a special weighing instrument to accurately measure pesticides. All weighing utensils should be cleaned after use, and the rinsed waste liquid must be properly disposed of away from the residence, water source and crops, and the utensils used for measuring pesticides should not be used for other purposes.

What medicine can make a tree rot roots?

If you want it to die completely, you can use glyphosate, remember, don't mix it with water, just put a bottle of glyphosate directly against the trunk and pour it to the bottom, if it doesn't rain, the sun is strong, you can see the tree start to wither in two days, and it will die completely in about seven days, but the land that runs out of glyphosate can't be planted immediately, and it will take a while to continue planting.

The correct way to use glyphosate:

1. Improve the weeding effect of glyphosate:

1.Glyphosate is an organophosphorus systemic conductive herbicide, the liquid medicine should be conducted to the underground rhizome tissue of weeds in large quantities, in order to achieve the ideal weeding effect, which requires weeds to have more leaves, before the use of weed leaf area is small, photosynthesis is not strong, then the root nutrition is conducted, at this time, the amount of liquid medicine into the root is rarely detected ridge hole, can not play a good weedicidal effect.

2.The photosynthesis is strong in the middle and late stages of weed growth, and the photosynthetic products are conducted from top to bottom. Therefore, one of the most important aspects of using glyphosate is to choose the best time to take it.

It is best to use medicine before flowering during the peak period of weed growth. Generally, annual weeds are 15-20 cm and perennial weeds are about 30 cm high, and the weeding effect is the best.

3.In determining the concentration of the drug must consider the type of weeds, generally grasses are more sensitive to glyphosate, can be killed by a low dose of liquid medicine, and the control of broad-leaved weeds to increase the concentration, for some rhizome propagation of malignant weeds, it is necessary to have a higher concentration. Weeds are older, drug resistance is improved, and the corresponding dosage should also be improved, such as when controlling orchard weeds, annual gramineous weeds can be used with 10% glyphosate 500-700 ml to 30-40 kg of water, and the control of annual broad-leaved weeds should be increased to 750-1000 ml, and the amount of perennial malignant weeds should be increased to 1250-1500 ml.

Second, the safety of glyphosate on crops when it is used:

Glyphosate is a biocidal herbicide that can cause a safety hazard for farmers if used incorrectly. When farmers use glyphosate for weeding, they often do not put a protective cover on the sprinkler head, and the glyphosate drifts away with the wind, causing pesticide damage to crops. There are also some farmers who do not clean the machine after use, and as a result, when spraying other pesticides, the residual glyphosate agent is sprayed on other crops, causing pesticide damage and causing losses to farmers.

There is a reason for root rot in plants, and it is common for the soil to be moist and waterlogged for a long time, and the vast majority of them are due to this reason. Of course, there are some root rots caused by diseases and fertilizers, although there are such cases, but they are generally relatively rare.

Generally, the more popular treatment method for rotten roots of plants is to clean up the rotten parts, then sterilize and disinfect, change the soil and replant. If it is a hydroponic plant with rotten roots, it is recommended to cut off the rotten part, sterilize and disinfect, and then dry it in a cool and ventilated place, and change it to soil cultivation, because it is easy to continue to rot if you continue to plant in soil.

Because the plants are different, you can be flexible when dealing with them, so let's take a look at them in detail.

1.Herbaceous plant.

Whether this kind of plant is hydroponic or soil-grown, once there is a rotten root, the first treatment method is to find a way to back up, because many herbaceous plants can be propagated by cuttings, so we first understand whether the plants we raise can be cuttings, if so, first cuttings to propagate backup, and then think about how to deal with rotten roots.

After the herbaceous plants are found to rot their roots, they are generally more serious, we can observe the growth of the plants, if the plants have wilted, there is not much room for salvage, and the effect of digging out and treating them is not large, but it accelerates death. If there are many flowers and plants in a pot, a few plants have problems, and there are normal growth, it is recommended to check whether the soil in the pot is waterlogged, whether it has been fertilized recently, etc., if there is to be improvement, such as water control, if there is more fertilizer, water more, and wash away the excess fertilizer.

2.Tubers, bulbous.

This kind of plant is easier to deal with than herbaceous plants, because there is a process of rotten roots, so when we find rotten roots, we can cut off the rotten part, and then apply it to the wound with plant ash, no or no coating, and then put the plant in the shade and ventilation to dry for 1-2 days, and after the wound heals, then re-pot, it is recommended to change the soil, and the survival rate is generally relatively high.

If the rot is more severe, as long as there is still healthy tissue in the root plate, there is still hope for recovery, but it cannot be directly potted and planted, you can use plain sand, vermiculite and other media to plant the roots, and then repot with ordinary medium after the roots.

3.Woody plants rot roots.

There are many woody plants that can also be cuttings, but the difficulty is relatively large, such as the moon season and other cuttings are easy, but if it is a fortune tree or the like, the cuttings are very difficult. Therefore, for woody plants, we must first understand whether the plants can be cuttings, and consider backing up first.

In addition, for many plants, especially large leaf potted plants, once there are rotten roots, the probability of recovery is actually not large, some flower friends of the fortune tree, when the rotten roots are found, in fact, it has rotted very badly, although the top of the stake looks healthy, but in the family, the probability of saving is almost 0, it is recommended to throw it away.

If the root rot is not bad, treat it in the same way as at the beginning, clean it and disinfect it for potting.

If it is caused by fungi, you can use methyl frost mildew! Wet soil can also cause root rot, so it's good to control the moisture!

The rotten roots of the plant are basically hopeless, which means that there is a problem with the soil or the plant itself, and you can transplant it to give it a try.

The cause of rotten roots may be too much water, or it may be insects, so changing the soil is the best way.

Glyphosate. If you want the tree to die completely, you can use glyphosate, do not mix with water, directly put a bottle of glyphosate, pour it to the bottom of the trunk, if it does not rain and the sun is strong, you can generally see the tree begin to wither in two days. It takes about seven days to die completely, but the land that runs out of glyphosate cannot be planted immediately.

It takes a while to continue planting. Extended Information: Tree Planting Considerations:

Users need to be aware that watering too much can lead to rot in the roots. The amount of watering should be reduced. Wait for the ridge of the soil to dry thoroughly before watering.

The soil must not hold water. In addition, if the weather becomes colder and the temperature drops, the roots and stems will be frostbitten, which cannot be saved. Generally, when the temperature is below 5, it cannot survive normally.

Only the roots rot occur, the roots can be cut off and soaked in a special disinfectant. Plant it with new soil and it will be able to re-root. If the main part of the plant rots, the chances of saving it are less than digging and closing.

Once the tissue in the trunk becomes soft and water accumulates, there is no way to save the crack.

Cut off the rotten roots, replace the disinfected soil, and re-cultivate.

1.The fleshy roots can be dried for a few days until the wound heals before planting.

2.Non-fleshy roots can be cut off to reveal new roots, planted in the shade for a few days to wait for the seedlings to slow down.
