Is it normal for Fugui bamboo to have black spots on its roots?

As long as there is no smell, it is normal.

1. The water has not been changed for a long time.

1. Reason: Many flower friends like to breed rich bamboo in the water basin, because no one cares for a long time will produce many bacteria in the water, too much metabolic waste accumulated in the water for a long time and lack of oxygen will affect its survival, so that its roots are black.

2. Solution.

The first thing we need to do is to cut off the black part with scissors, be sure to cut it clean, there can be no leftovers, otherwise the remaining places will produce residual bacteria, after cutting clean, the water must be replaced, and then loaded with new water quality, and the nutrient solution should be poured in, and continue to insist on changing the water in this way in the future, do not leave it alone.

In addition, we also need to use a diluted potassium permanganate solution to soak the bamboo body for disinfection, the degree of dilution can not make the solution purple, just let it appear watermelon color, after soaking, you can wash it with clean water and then put it into new water to breed, the water is best to use boiled cold water or pure water.

2. Infection. 1. Reasons.

If it is not maintained properly during the usual maintenance, it will be infected by some germs, and it may also make its roots black.

2. Solution.

If the plant is infected with the virus, we have to cut off the infected area, but sometimes the blackened part is not the infected part, which may cause other reasons to cause its infection, we need to gently pinch the plant with our hands, if some places are soft, it means that it needs to be reduced.

Our incision has a requirement, that is, we need to keep the incision clean, not to let the incision place produce secondary infection, and put it in a ventilated place to let the wound dry, so that it can be put back in the bottle for normal maintenance.

3. Fertilization. 1. Reasons.

This phenomenon will also occur if it is not done correctly when fertilizing, because too much fertilizer will make the plant unbearable, and the fertilizer concentration will be too large to cause root burning.

2. Solution.

If this situation occurs in fertilization, what we have to do is to add some brandy to it every three weeks, the amount is not too much, and you can also add some vitamin C, which can produce a certain effect, but there is no guarantee that it can be certain, so it still depends on your usual careful maintenance.

The leaves of Fugui bamboo have many black spots because they are infected with leaf spot disease.

Leaf spot pathogens are mainly transmitted by wounds, and the incidence of leaf spot bacteria is severe under wet conditions. The most cases occurred in Guangdong in May and September, which was due to the high temperature and humidity at this time, coupled with the frequent wounds caused by typhoons and showers, which made the disease very easy to spread. The disease is highly contagious and can rot the leaves and stems of plants.

The lesions of Fugui bamboo are brown spots at the beginning with yellow edges; After expansion, the lesion is nearly rounded, **gray, the margins are black-brown, and the periphery is yellow; Black granules appear on the lesions under wet conditions.

The disease begins to occur more often on the leaf tip or leaf margin and on the leaves

At the beginning of the disease, it is water-stained, dark green and irregular.

DAO is the sick version.

spots, and gradually spread right to the upper leaves.

Enlarge; semicircular to amorphous in the middle stage, with dark brown margins and distinct demarcations; In the later stage, the outer edge of the leaf lesion has a yellow halo, and the middle part of the spot is gray-brown or gray-white to yellowish-brown. The spotted wreak is obvious or indistinct, and the lesions show small black spots, and the leaves begin to gradually turn yellow and die. Once the lesion spreads to the leaves, young leaf buds, main stems, and the base of the leaf stem, when the disease is severe, the stems and leaves will quickly wilt and die.

Under the weather conditions of continuous rain and fog and dew, the diseased leaves spread, and the plant growth is poor, which seriously affects the effect of leaf viewing.

Repeated infections can occur multiple times during the growth period. Temperatures are elevated, and humid weather conditions are conducive to the onset of the disease. The disease can occur from mid-March to October every year, the optimal temperature for germination of the fungus is 22-28, and the disease is the most severe in the south from May to June.

Secondly, the incidence is also more severe in summer and autumn. Generally, the primary lobe is the first to occur.

Prevention and control methods. 1. Strengthen the maintenance and management of Fugui bamboo, and should not be planted too densely; Pay attention to avoid frost damage and frost damage; Moist irrigation, reasonable fertilization, and increased phosphorus and potassium fertilizers to promote growth and improve disease resistance.

2. In winter and spring, diseased leaves should be cut off and dead leaves should be cleaned up, and burned in a concentrated manner to reduce the onset of disease, and quicklime should be sprinkled for sterilization and soil disinfection; Or spray 50 times of 50 compound carbendazim 500 times to prevent disease, and the prevention effect is better.

The air is not good, or there is not enough fertilizer or water.

Fugui bamboo leaf spot disease Symptoms: The initial stage of the lesion is brown spots, and the edges are yellow; Extend.

Posterior lesions are nearly rounded, **gray, black-brown on the margins, yellow around the periphery; Black granules appear on the lesions under wet conditions. Prevention and control methods: (1) Prevent the plants from being too dense and keep ventilation and light transmitted.

2) At the beginning of the disease, spray 3000 times of 42 grams of bacterial powder, or 1000 times of 88 hydrate, or 800 times of 25 copper ammonia, every 5 7 days, and spray 2 3 times.

The air is not good, or there is not enough fertilizer or water.

Native to the Gali Islands and tropical regions of Africa and Asia, Fugui bamboo has been introduced to China in large quantities since the late 80s of the 20th century. It is very common in ordinary families, because the shape is tower-shaped, and the ornamental value is high. In order to sell this plant, people added the greeting of "flowers bloom and wealth, and bamboo reports peace" to it.

As an ornamental foliage plant, it is mostly cultivated with water. Change the water regularly and you will be able to grow. What should I do if there is yellowing and black root when raising rich bamboo?

The corresponding solution is also to do it according to the growth habit of Fugui bamboo. Fugui bamboo needs light, nutrients, and pruning to grow. If you can't raise rich bamboo, there are problems with these three points.

The corresponding solution is:

1. Light. The yellowing of the leaves has a lot to do with light. Fugui bamboo is a shade-tolerant plant, check if you are often exposed to strong light. Usually the maintenance staff put the rich bamboo in a cool place, but it cannot be completely out of sight.

Keep it cool, strong light will also bring heat, which also has restrictions on the growth of Fugui bamboo. The indoor temperature is 20 degrees Celsius.

2. Nutrients. The yellow leaves of Fugui bamboo grow slowly, and some of the black roots are lacking nutrients. Most people raise Fugui bamboo is water-raised, which is simple to raise, but has few nutrients, and needs to change water regularly. This has caused a shortage of nutrients, although it will grow, but it is willing to have problems, and the rich bamboo does not grow strong.

It is best to use fertilizers, organic fertilizers and compound fertilizers. Convert this fertilizer into water, and then fertilize Fugui bamboo. Fertilizing once a week works best.

3. Pruning. Most people rarely prune when raising rich bamboo. Too many branches and leaves, one is to affect the appearance, and the other is to cause the loss of nutrients and cause yellowing. Regular pruning is a must, not only for the leaves but also for the roots that are in trouble.

Scientific fertilization: Fugui bamboo sends out new roots, so it is necessary to fertilize. According to the growth situation, compound fertilizer is applied. It can be used together with urea, combined with spraying extra-root fertilizer, spraying with plant auxins such as new branches or spraying Shibao to promote growth balance, thick leaves and stems, and improve stress resistance.

The basic essentials of water culture: cut off some of the leaves that enter the water surface before cultivation, and the incision is at an angle of 45 degrees, and it is smooth and conducive to absorbing water and nutrients. Change the water once every 3 to 4 days, do not move the position or change the direction for 10 days, and the silver-white fibrous roots can grow in about 15 days.

It is not advisable to change the water after rooting, and it can only be watered in time after the water evaporation is reduced.

Water nourishes wealth and bamboo roots are black, mainly because there is no water change for a long time, lack of oxygen in the water, plant cell respiration is needed for oxygen, lack of oxygen plants will temporarily carry out anaerobic respiration, produce alcohol, for a long time will harm the plant, resulting in plant root cell alcoholism, a large number of deaths, serious cause rotten roots, it is recommended to change the water more.

You can also use sharp scissors to cut all the blackened roots, a little black can not be left, planted on the drainage hole of the flower pot, cover it with two tiles, put three centimeters of coarse-grained soil on the base fertilizer, remember to cover the soil on the base fertilizer, so as not to cause damage to the fertilizer Put the plant in the middle, add the soil to two centimeters below the edge of the pot, so as to facilitate watering in the future; Then put the flowers in a cool and ventilated place, spray the leaves frequently, and you can manage the fertilizer and water normally after half a month.

1. Change the water frequently. What we need to do is to dispose of the black part, which can be cut off with scissors, and it needs to be emphasized here that it must be removed cleanly, and there can be no leftovers. After that, what we have to do is to change the water, at this time we have to control the water quality, and then remember to change the water on time.

2. Frequent maintenance. At this time, what we need to do is to cut off the infected part, at this time we need to pay special attention to the point, that is, we see that the blackened part is not necessarily the infected part, so we have to pinch it, if there is a soft place, there is also a need to cut it. 3. Water should be disinfected.

In addition, we also need to soak the bamboo body with diluted potassium permanganate for disinfection, here we need to grasp the degree of dilution, not to make the solution purple, as long as it shows watermelon red. More about what to do if the rich bamboo roots are blackened, enter to see more content.

The roots of Fugui bamboo are black and smelly, may be infected by bacteria, at this time, it is necessary to cut off the rotten parts in time, and then disinfect the planting container with alcohol, and replant Fugui bamboo, it is recommended to change the water every five days, and drop a few drops of nutrient solution, which can be placed in a astigmatism environment, and patiently wait for Fugui bamboo to re-root.

The solution to the black and smelly roots of Fugui bamboo1. Cut off the rotten roots

If you find that the roots of Fugui bamboo are black and smelly, it is likely to be infected by bacteria, then you need to take it out of the soil or hydroponic container, and then cut off the rotten roots in time.

2. Disinfection treatment

After the roots of Fugui bamboo are treated, the container needs to be wiped with alcohol or carbendazim, and then placed in the sun to dry for a day, and the roots of Fugui bamboo also need to be sprayed with carbendazim in an appropriate amount, and then replanted.

3. Change the water in time

If the roots of Fugui bamboo are black and smelly after replanting, you need to change the water every five days to keep the water clean, or you can drop a few drops of nutrient solution into the water in an appropriate amount to provide nutrients for Fugui bamboo, and patiently wait for the roots of Fugui bamboo to re-root.

4. Strengthen management

With the help of sunlight, Fugui bamboo can grow better, but if it is exposed to direct sunlight, it is easy to dehydrate Fugui bamboo, which will make it lose its vitality.

There are too many roots of Fugui bamboo that need to be dealt with. For soil-grown plants, too many roots will occupy a lot of space in the pot, affecting the ventilation inside the soil, which is not good for plant growth. Moreover, so many roots cannot get enough nutrients from the limited soil, but will consume too much nutrients in the plant, making it grow poorly.

For hydroponic plants, too many plants will not only consume nutrients, but also directly affect the ornamental value of the plants, so it is recommended to prune.

1. Cut rotten roots: If you feel that there are too many roots of Fugui bamboo, you need to take it out of the original cultivation substrate first, and use scissors to cut off the black and rotten roots on it. These roots are not only unable to absorb water and nutrients, but are prone to attracting bacteria and are of no value to the plant.

2. Cut the dense roots: In addition to the black roots and rotten roots, the overly dense roots also need to be properly pruned, and the roots that grow together should be properly cut and thinned with scissors. This helps to increase ventilation while reducing nutrient consumption.

3. Disinfection and replanting: After pruning, the bottom of the plant should be placed down and soaked in disinfectant for 15-20 minutes to sterilize the wound. After that, leave it in a cool and ventilated place to dry, and then replant it back in soil or water.
