Rich bamboo means rich and valuable bamboo. The beauty of the rich bamboo is inseparable from its auspicious name. It has long, thin and natural leaves, green leaves, its stem nodes show the characteristics of looks like bamboo nodes, but not the real bamboo. However, there are some problems such as yellowing of leaves in aquaculture. This paper analyzes ten situations and solutions:
Cause analysis and treatment methods: 1. Too much water causes the leaves to turn yellow (watery yellow): due to too much water for a long time, the leaves turn yellow, which is manifested in the bright yellow of the young leaves, no obvious change of the old leaves, small yellow and green roots, and no long shrinkage of the new shoots.
Solution: watering should be done according to the regulations. If it is heavy, you can take off the basin and put it in the shade to dry the soil before putting it back into the basin.
2. Yellow leaves (dry yellow) of rich bamboo caused by long-term water shortage: yellow leaves caused by lack of water or insufficient watering. The old leaves are withered and shed from bottom to top, but the new leaves generally grow normally.
Solution: the amount and times of watering should be increased appropriately.
3. If the branches and leaves of the rich tree grow too luxuriant and have not been pruned for a long time, the light in the branches and leaves inside is insufficient, which is likely to cause the leaves to turn yellow and fall off.
Solution: trim should be strengthened in time to make it ventilated and transparent.
4. Lack of sunlight leads to yellow leaves (lack of light yellow): long term in the shade or dark light, there will be yellow leaves, defoliation, or even death.
Solution: Fortune tree likes light, but it can't stand strong direct light. It's better to use half shade or scattered light. Only in winter, it needs better light conditions to grow well. From the end of April, you can choose the sunny and warm noon, move the basin out of the outdoor or balcony, directly see the sun for 1-2 hours, and gradually extend the time, it will have a good breeding effect.
5. Too high temperature makes the leaves of the rich bamboo yellow: for the rich trees that prefer warm and humid environment, if they are exposed to the sun under high temperature, the transpiration of the plants is too much, the water and nutrients in the roots are in short supply, and it is easy to cause the tip of the leaves to wither or the leaves to fall off.
Solution: move to a cool and well ventilated place in time.
6. Low temperature leads to yellow leaves of rich bamboo: rich trees like warm and humid environment. Their growth temperature is 20-30 ℃. If the temperature is lower than 18 ℃, rich trees will stop growing. If the temperature is as low as 10 ℃, they can also adapt, but the lowest temperature can not be lower than 5 ℃. Otherwise, freezing damage will occur. The light ones will be scattered with yellow leaves, and the heavy ones will die.
Solution: heat preservation facilities in winter.
7. Too much fertilizer application causes the leaves to turn yellow (fat yellow): due to too much fertilizer application or too high concentration, the top of the new leaf appears dry brown, and the old leaf tip is dry scorched, withered, yellow and fallen off. Generally, although the leaf surface is thick and glossy, it is mostly uneven.
Solution: stop fertilizing or wash the fertilizer with water.
8. Rich bamboo leaves yellow due to long-term lack of fertilizer (lack of fertilizer yellow): potted flowers only water for a long time without fertilizer, do not change pots for many years, the roots form a mass, the plants do not get fertilizer, so that the leaves yellow.
Solution: in addition to timely basin change, usually thin fertilizer should be applied frequently. Wei
9. Alkaline soil and water lead to yellow leaves of rich bamboo: in most areas of North China, the soil and water contain more salt and alkali, which is not suitable for planting rich trees that like acid. Because of the lack of iron elements that can be absorbed by the soil, the leaves of rich trees will gradually turn yellow.
Solution: pay attention to the selection of acid soil when planting, and often pour alum fertilizer water during the growth period.
10. Diseases and insect pests lead to the yellow leaves of the rich bamboo: leaf spot is a common disease of the rich tree. The symptom is that there are a few spots first, and then the spots gradually extend to the whole leaf, and fall off.
Solution: garlic juice can be used for spraying sterilization.
Tips on home furnishing, fortune making, fortune making, and bamboo maintenance: no matter what environment you are raising, do not change the place you place suddenly. Changing the position requires a gradual process of adaptation. If you suddenly transfer the plant from the shade to the strong light, it will burn the leaf surface, scorch the edge, and affect the beauty.
