[tortoise back bamboo] what if the leaves of the tortoise back bamboo turn yellow

Tortoise-backed bamboo is a family plant that many people like to breed. When planting tortoise-backed bamboo in the family, if it is not properly maintained, it is very easy to produce yellow leaves, which will affect the ornamental value, and seriously affect the growth of tortoise-backed bamboo and even the death of plants. Let's take a look at the causes and solutions that affect the yellowing of tortoise back bamboo leaves.

Analysis on the causes of yellowing of bamboo leaves in tortoise back

When yellow leaves occur in tortoise-backed bamboos, it is necessary to find out the causes in time and sort out several causes of yellowing of tortoise-backed bamboo leaves.

1. Yellowing of tortoise back bamboo: soil reason

The newly added tortoise back bamboo has not yet passed the basin period after changing the basin. Both clayey and micro-clayey soils will affect the growth of roots in different degrees. If the soil permeability is not good or does not change soil for a long time, it may cause soil hardening and affect the respiration of tortoise back bamboo, so that the growth of tortoise back bamboo is poor and the leaves turn yellow.

2. Tortoise back bamboo yellowing: light

The tortoise back bamboo is resistant to shade, but if it is placed in a shaded environment for a long time, it will affect photosynthesis and turn the leaves yellow. at the same time, the tortoise back bamboo should not be placed in strong light, and attention should be paid to shade in summer. strong light will cause the leaves of the tortoise back bamboo to burn and turn yellow. You'd better give some scattered light to the turtle's back bamboo.

3. Turtle back bamboo yellowing: fertilizer

The yellowing of the lower leaves should be due to lack of fertilizer; iron is a necessary raw material for plants to synthesize chlorophyll. If there is not enough iron in the soil or fertilizer, it will affect the synthesis of chlorophyll, resulting in chlorosis and yellowing of leaves. If the leaves are yellowed due to iron deficiency, alum fertilizer should be applied or 0.1% ferrous sulfate solution should be sprayed.

4. Tortoise back bamboo yellowing: too much or too little watering

More water will cause root rot phenomenon, less water will make the plant lack of water and poor growth, these two cases will cause the yellow leaf phenomenon of tortoise back bamboo. The correct way is to water regularly and thoroughly at one time to keep the surface of the basin soil slightly dry. when the air is dry, sprinkle water on the environment and the leaves of the tortoise back bamboo.

5. Tortoise back bamboo yellowing: frozen

The suitable temperature for the growth of Phyllostachys pubescens is 20 ~ 25 ℃, and the temperature at night in winter is not lower than 10 ℃ at seedling stage. Mature plants can tolerate 5 ℃ in a short time, and freezing injury is easy to occur when the temperature is lower than 5 ℃, which causes the leaves of Phyllostachys pubescens to turn yellow. In winter, the roots of Phyllostachys pubescens should be kept warm in order to enhance the cold resistance of the plant. But don't put the turtle bamboo directly on the radiator or next to the air conditioner.

6. Turtle back bamboo yellowing: poor ventilation

When the ventilation is not good, it will cause the stuffy yellow leaves of the tortoise back bamboo. To maintain good indoor ventilation, you can also put the tortoise back bamboo indoors during the day and move outside at night.

7. Yellowing of tortoise back bamboo: disease

The gray spot of tortoise back bamboo, also known as leaf blight, is a common disease of tortoise back bamboo. When the disease is serious, it can cause leaf death. Usually the indoor temperature is low or the disease is more serious after being smoked or pest, and the disease often occurs on the old leaves. Control, strengthen cultivation management, pay attention to control room temperature, should not be too low. Timely control of insect pests, cut off diseased leaves or leaves of diseased tissue, centralized destruction. Chemical control can be sprayed with 0.5% Bordeaux solution or 50% acetaminophen 1000 times.

Propagation methods of Phyllostachys pubescens: 1. Ramet propagation

In summer and autumn, the side branches of large tortoise-backed bamboos are chopped off in whole segments, with partial aerial roots, and directly planted in wooden buckets or bowls, which not only has a high survival rate, but also has a fast forming effect, which is now the most commonly used and one of the simplest methods in the reproduction of tortoise-backed bamboo.

Propagation methods of tortoise back bamboo: 2. Cutting propagation

Another propagation method of Phyllostachys pubescens is cutting propagation. Stem node cutting can be used in spring and autumn, and the cutting effect is the best from April to May in spring and September to October in autumn. Cuttings are suitable for stem node incision healing and rooting during this period of time, and survive quickly. Cuttings selected stem tissue full, robust growth of the current year side branches, cuttings length of 20-25 cm, cut off the leaves at the base. Retain the upper leaflet, cut off the long aerial root, retain the short aerial root, in order to absorb water, conducive to hairy roots. The mixed substrate of coarse sand and peat or rotten leaf soil was used to keep 2527 ℃ and high air humidity after insertion, and it began to take root about one month after insertion. After the cuttings took root, the axillary buds on the stem nodes also began to sprout and spread leaves. In order to accelerate seedling growth, keep more than 10 ℃ at room temperature, strengthen fertilizer and water management, and seedling shaping can be used as a commodity in the second year after planting. If you need to hang embellishment, you can prepare a wooden frame or iron frame container, which is filled with palm skin, put on the fertile rotten leaf soil, and plant the rooting and surviving turtle back bamboo as a hanging basin commodity.

What to do about the yellowing of the leaves of the bamboo on the back of the tortoise? the causes and solutions of the yellowing of the leaves of the bamboo on the back of the tortoise

Because tortoise-backed bamboo is a very good indoor ornamental plant, many people like to raise it, but when the leaves of tortoise-backed bamboo turn yellow in the process of breeding, what should we do? Let's take a look at the causes and solutions of the yellowing of tortoise-backed bamboo leaves.

The main results are as follows: 1. The sudden change of environment leads to the yellowing of bamboo leaves: the reason for the sudden change of environment is that the soil, temperature, humidity and light suddenly change too much. Phyllostachys pubescens is originally a parasitic plant, and its well-developed root system is fleshy root, which requires high porosity and permeability of soil. Both clayey and micro-clayey soils will affect the growth of roots in different degrees. If the soil permeability is not good or does not change soil for a long time, it may cause soil hardening and affect the respiration of tortoise back bamboo, so that the growth of tortoise back bamboo is poor and the leaves turn yellow.

Solution: family potted turtle back bamboo, the cultivated soil can be mixed with 2 parts of mature loess, 1 part of honeycomb coal ash and 1 part of chicken manure. In this way, it can not only ensure the air permeability of the potted soil, but also meet the fertilizer requirements for growth.

2. Excessive watering leads to the yellowing of the leaves of the tortoise-backed bamboo (water yellow): more water will cause the rotting root phenomenon of the tortoise-backed bamboo, which will cause the yellow leaf phenomenon of the tortoise-backed bamboo.

Solution: the tortoise back bamboo should be watered regularly and thoroughly at one time to keep the surface of the basin soil slightly dry. when the air is dry, sprinkle water on the environment and the leaves of the tortoise back bamboo.

3. Long-term lack of water leads to yellowing of leaves (dry yellow): lack of water will make the plant grow badly due to lack of water, which will lead to the phenomenon of yellow leaves.

Solution: pour enough water regularly

4. Exposure to the sun causes the leaves of the tortoise back bamboo to turn yellow (burning yellow): if the tortoise back bamboo is placed in strong light, the strong light will cause the leaves of the tortoise back bamboo to burn and turn yellow.

Solution: tortoise back bamboo should pay attention to shade in summer.

5. Air dryness leads to yellowing of tortoise back bamboo leaves: when the air is dry, it will cause stuffy yellow of tortoise back bamboo leaves.

Solution: to maintain good indoor ventilation, you can also put the turtle back bamboo indoors during the day and move outside at night.

6. Lack of sunlight leads to yellowing of leaves (lack of light and yellow): Phyllostachys pubescens can withstand shade, but putting it in shade environment for a long time will affect photosynthesis and make the leaves yellow.

Solution: it is best to give the tortoise back bamboo some scattered light.

7. The leaves of Phyllostachys pubescens turned yellow when the temperature was too low: the optimum temperature for the growth of Phyllostachys pubescens was 20: 25 ℃, the temperature at night in winter was not lower than 10 ℃, the mature plants could tolerate 5 ℃ in a short time, and the leaves of Phyllostachys pubescens were yellowed when the temperature was lower than 5 ℃.

Solution: in winter, the roots of the tortoise-backed bamboo should be properly kept warm to enhance the cold resistance of the plant, but do not put the tortoise-backed bamboo directly on the radiator or next to the air conditioner.

8. Long-term lack of fertilizer leads to yellowing of leaves (lack of fat yellow): iron is a necessary raw material for plants to synthesize chlorophyll. If there is not enough iron in soil or fertilizer, it will affect the synthesis of chlorophyll, resulting in chlorosis and yellowing of leaves.

Solution: if the leaves are yellowed due to iron deficiency, alum fertilizer should be applied or 0.1 mi 0.3% ferrous sulfate solution should be sprayed.

9. Diseases and insect pests lead to the yellowing of the leaves of tortoise back bamboo: the gray spot of tortoise back bamboo, also known as leaf blight, is a common disease of tortoise back bamboo.
