Don't water it too hard, don't water it if necessary, and water it thoroughly.
If there is tooth decay, it will be removed in time, which will look good and will not affect others.
Pay attention to the light,
You water it too often. I think.
The yellow stem of Fu Guizhu's son.
Root injury or necrosis affects the absorption of water and nutrients, so it will turn yellow.
How to solve the problem that rich bamboo turns yellow from bamboo pole?
Fu Guizhu stem rot
It depends. Several bamboo plants were infected. It is recommended to update them all.
The disease caused the death of Phyllostachys pubescens and reduced its ornamental value. High temperature and humidity are common from May to September, mainly damaging leaves and stems.
First of all, pathogens
This disease is a fungal disease, which is caused by Phytophthora.
Second, the occurrence law
Due to poor management of hydroponic bamboo, when it is mixed with substrate or soil-grown flowers, germs may splash on bamboo when watering, causing diseases.
Third, prevention and control methods
1, removing diseased plants.
Only by strengthening management can this disease be controlled. The water used for hydroponics must be clean and isolated from flowers planted in soil; The basin water is frequently changed, on the one hand, the water quality is not easy to be polluted. On the other hand, increasing dissolved oxygen in water is beneficial to the healthy growth of Fu Guizhu and improving its disease resistance.
What should I do if the bamboo pole turns yellow?
There are several main reasons for the yellowing of leaves and stems of Phyllostachys pubescens: 1) Phyllostachys pubescens can safely overwinter at room temperature of 6~8 degrees. If the room temperature is too low, or it is very cold outside, it will be moved into a cool cold room. 2) After winter, if you don't often add water or change water, there is no nutrition, and it will be placed in a cool room for a long time, which will also cause such a situation; 3) Plants are bought at the wrong time, and it is also one of the reasons that they haven't taken root in winter. Rescue measures: 1) Remove the yellow leaves and stems immediately, and the space can be replaced with yellow plants. 2) Keep sufficient indoor light and the lowest room temperature at 6~8 degrees. In case of low temperature, cover the basin with 1~2 plastic bags, and keep away from the glass window at night. Hydroponics is also possible, but it is not as lush as soil culture. Potted soil should be changed once a year in early spring, and sandy soil rich in humus is ideal.
What should I do if the trunk of Fu Guizhu turns yellow and withered?
There are many reasons why the leaves of Fugui bamboo turn yellow. See what kind of reason you belong to, and you can prescribe the right medicine.
The following are the reasons why the leaves of Fu Guizhu turn yellow and the treatment methods I provide for you:
.
The scorching yellow strong sunlight shines directly on the rich bamboo, which is easy to cause the leaf tips and leaf edges to wither, and yellow spots appear at the sunrise of the leaves. Move to the shade.
Yellow leaves are shaded for a long time, so the leaves don't get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off. Supplementing light can avoid this disease.
The yellowing of Fu Guizhu caused by high concentration of excessive fertilization or fertilizer yellow is characterized by dry brown at the top of new leaves, thick and dull leaves, unsmooth protrusions and brown shedding of old leaves. Fertilization should be stopped immediately, and some fertilizers should be washed carefully with a lot of cleaning.
The lack of fertilizer yellow shows that the color of young leaves turns pale to yellow or light green, and the old leaves turn normal or gradually from green to yellow. Apply thin fertilizer frequently at ordinary times and replenish some alum water in time. Fu Guizhu is a foliage plant, so nitrogen fertilizer should be applied.
1. I bought a rich bamboo heel, cut off the heel first, and then put it in a ventilated place for three to five hours to let the cut mouth air-dry and heal, so that no bacteria will enter the heel to rot;
2. Put the air-dried rich bamboo in a vase with good water. A few days before the new heel grows, change the water frequently and clean the heel. You don't need to change water until the new heel grows, just make sure that the water in the vase doesn't pass over the heel, and there is not too much water, so that there will be no lack of oxygen in the heel.
How did the stems of hydroponic bamboo slowly turn yellow and die?
Fu Guizhu's skill of lifting water
Fu Gui bottle bamboo hydroponics should master the following points:
1. Cut off the leaves at the base of the cutting before entering, and cut the base into oblique corners with a sharp knife. The incision should be smooth to absorb water and nutrients. Change clean water every 3 -4 days 1 time, 10 day keeps the same direction, and 15 day grows silvery white fibrous roots.
2. It is not advisable to change water after rooting, and water can be added in time after water evaporation is reduced. Changing water frequently can easily lead to yellowing of leaves.
3. After rooting, apply a small amount of compound fertilizer in time to make the leaves oily green and the branches stout. If fertilization is not applied for a long time, the plants will grow very thin and the leaves will turn yellow easily. However, fertilization should not be too much, so as not to cause "root burning" or ineffective growth. Apply compound fertilizer l times a month in spring and autumn. According to the data, in order to prevent overgrowth, it is best to inject a few drops of brandy into the bottle every three weeks or so and add a small amount of nutrient solution to keep the leaves green.
4. Don't put the rich bamboo beside the TV or on the ground where air conditioners and electric fans often blow, so as to avoid the dry tip and edge of leaves.
Your hydroponic bamboo leaves are yellow, and you can find the reasons from the following two aspects: First, check the water quality, mainly to see if the roots are fresh. If the root rot is caused by water quality, it is necessary to switch to cold boiled water. Second, check the lighting conditions of the place, such as too dark light, stuffy and stuffy, dry air and so on. Will cause the leaves to turn yellow; However, if the light in the place is too strong, it will also lead to yellowing of the leaves and absence.
What about the yellow-leaf bamboo? If it is caused by light, you can cut off the yellow leaves and the rotten roots first, and then create a clean, temperate, cool, humid and evenly distributed environment for it. If the root rot is caused by unclean water, you can cut off the yellow leaves first. When the symptoms are not serious, change the water frequently and put it in a ventilated and sunny place for restorative maintenance. When the symptoms are serious, pesticide should be sprayed properly or a small amount of bactericide should be added to the water tray.
Other issues "
It is evergreen woody, likes high temperature and high humidity environment, and is also resistant to shade and waterlogging, and has certain cold resistance. When the temperature is lower than 10℃ in winter, the leaves will turn yellow and fall off. As indoor ornamental plants, generally no nutrients are added to the soaking solution of Phyllostachys pubescens to prevent the stem nodes from rotting. It is best to use tap water or cold boiled water for overnight storage. Change it every 65,438+08 days to 65,438+05 days, and change it every 5 to 7 days in summer, but only pour out half and add a new half each time, otherwise the root system will not adapt. If you want to keep the hydroponic bamboo growing, you can add a small amount of urea and potassium dihydrogen phosphate aqueous solution to the soaking solution, the concentration can be controlled at about 0. 1%, and change it once every half month, or you can spray the fertilizer solution on the leaves. When more new buds grow, the diseased buds and dyed buds should be cut off as soon as possible, otherwise the whole pot of rich bamboo will be damaged; On the premise of not affecting the overall shape and appreciation of Fu Guizhu, it is also necessary to carry out adaptive thinning. Add a quiet, warm and happy atmosphere.
Not only is the temperature low, the air humidity low and dry, but this situation will also occur.
Fuguizhu originated in the Canary Islands and tropical areas of Africa and Asia, and has been widely introduced and cultivated in China. Its nature likes high temperature and high humidity environment, has low requirements for light, and is also resistant to shade. Suitable for growing in sandy loam with good drainage. The optimum growth temperature is 20-30℃, and the overwintering temperature is 65438 00℃.
Fu Guizhu is propagated by cutting. Pruning is combined with plastic pruning. As the plant grows taller, the leaves at the base of the stem often fall off, and the plant deformation is poor. In the growing season, the stems can be cut into 5- 10 cm as cuttings, or vermiculite or river sand. Generally, it can take root and sprout in 1-2 weeks. Potted bamboo can be planted with humus soil, garden soil and river sand in the same amount, or with coconut bran and humus soil and a small amount of base fertilizer as cultivation soil. The key to management is to master humidity and temperature. During the growing period, the basin soil should always be kept moist, and the leaves should always be sprayed with water to maintain a high environmental humidity. If it is too dry, the nib will dry up. Pot soil should not be too wet in winter, but water should be sprayed on the leaves frequently, and at the same time, attention should be paid to cold protection to prevent the leaves from yellowing, shrinking or even falling off. In May-September, liquid fertilizer or granular compound fertilizer is applied 2-3 times a month to keep the leaves green and bright. The requirements for illumination are not high, and it is suitable for growth under bright scattered light, and direct sunlight should be avoided. If exposed or dried in the sun, the leaves will be rough, scorched and dull, which will reduce the ornamental value. ...& gt& gt
Why does the trunk of the rich bamboo turn yellow?
Why does hydroponic bamboo turn yellow?
There is too much water in the vase, so don't change the water frequently. Usually, clean water is replaced every 3-5 days. When there is little water, pay attention to replenish water and oxygen. Don't change the water too often, the leaves will turn yellow easily. And often scrub the leaves to keep them clean and Liang Guang, and enhance their photosynthesis. Pay attention to these, Fu Guizhu leaves will not turn yellow easily. If we just remove its yellow leaves, it will only turn green in a short time, not for a long time.
Soil culture
1, too much water. The yellow leaves caused by long-term watering show that the young leaves are yellow and dull, and the old leaves have no obvious changes. The roots are small yellow-green, and the new buds do not shrink. To control the water, you can take off the basin when it is serious, dry the soil in the shade and put it in the basin.
2, caused by drought. The leaves turn yellow because of lack of water or water. Old leaves wither and fall off from bottom to top, but new leaves generally grow normally. The amount and frequency of watering should be appropriately increased.
There is too much fertilizer. Because of too much fertilization or too high concentration, the new leaf tip appears dry brown, and the old leaf tip also appears dry brown. The leaves are generally plump and shiny, but most of them are uneven. Should stop pouring fertilizer or rinse fertilizer with clear water.
4. Lack of fertilizer. Potted flowers are only watered for a long time without fertilization, or the pots are not changed for many years. The roots must form a ball, and the plants can't get fertilizer, which makes the leaves yellow. In addition to changing pots in time, we should also apply thin fertilizer frequently. For example, rich bamboo often lacks iron and yellow leaves. Woody flowers in greenhouse often have yellow leaves because of the great changes in soil fertility conditions, which are characterized by obvious young leaves, light old leaves, yellow mesophyll and green veins, forming a typical network; This solution can be solved by applying ferrous sulfate aqueous solution. The method is as follows: 7 parts of cake fertilizer, 5 parts of ferrous sulfate and 200 parts of water are poured into various liquids.
5. The sun burns. I like wet potted flowers and foliage plants, such as chlorophytum, evergreen, Eupatorium odoratum, Hosta, etc. If the leaves often appear yellow tips after being exposed to strong sunlight, they should be placed in the shade.
Can the pole of Fuguizhu be eaten when it is yellow?
The reasons for the yellowing of leaves of Fuguizhu in hydroponics are as follows: First, the water is too deep, resulting in hypoxia and yellowing of leaves, so the water level in the bottle can be reduced to 1-2 cm at the bottom and top of Fuguizhu. Second, fertilization is too thick, and hydroponic bamboo can be applied with thin fertilizer. Depending on the concentration of fertilizer, 3-5 grains of urea can be added to 100 ml water. Thirdly, if the temperature is too high, the optimum temperature range of Bambusa bambusa is between 20-25℃, which will cause discomfort. Fourth, the light is too weak or too strong, and it is best to have a semi-cloudy or scattered environment, so you can't block the sun or direct sunlight. Fifth, the air conditioner blows, and the placement position should avoid the cold air blowing of the air conditioner, and the natural wind can.
What should I do? The poles of Fugui bamboo are all yellow. Is there any saving? Is there something wrong with the root ~ 10 score
This is difficult to deal with.
Fu Guizhu raised bamboo seeds for three years, and suddenly all the stems turned yellow. How to save it?
If the top of the upper segment is not yellow and heated above 20 degrees, the upper segment can be cut off in the green part of the stem and re-rooted. You can't live at low temperature.
