Causes and treatment methods of yellowing of leaves of Phyllostachys pubescens
Tortoise back bamboo is a famous indoor potted foliage plant because of its beautiful plant shape and peculiar leaf shape. Although it is not difficult to raise the tortoise back bamboo, if we do not pay attention to the feeding method, it will often lead to the yellowing of the leaves of the tortoise back bamboo. Although the yellowing of leaves is a common problem in plants, if we want to solve the problem, we still need to find the reason to solve it correctly.
Tortoise back bamboo
1. Soil discomfort
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.

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. 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.
Solution: 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.
