The reason why the leaves of chlorophyllous yellow chlorophyllous yellow solution

Many friends raise all kinds of flowers and plants in their homes, which are not only beautiful in appearance, but also purify the air. However, not everyone is a master of farming, and it is inevitable to encounter thorny things when raising plants, and they will be caught by surprise when their beloved plants get sick. Let's take a look at the yellow leaves of Cymbidium. What should we do?

First, the function of hanging orchid

Hanging orchid has a very strong function of absorbing toxic gases, if the general room raised 1 to 2 pots of orchids, the poisonous gas in the air can be absorbed. According to scientific analysis, the orchid can absorb 95% of carbon monoxide and 85% of formaldehyde in the air. Therefore, the hanging orchid is not only an excellent hanging leaf plant in the room, but also a good indoor air purification flower, so it has the laudatory name of "green purifier".

There are many kinds of hanging orchids, which are common, such as orchids, purple orchids, flower orchids, gold leaf orchids, silver orchids, peony orchids and so on. Among them, the branches of the orchid are not separated from the leaves, the leaves are drooping, and the leaves are dark green, blooming in June and July every year, and there are two kinds of flowers: yellowish and white; the purple orchid is also called Cymbidium, the main vein of the leaf is purple, the branches are nodular, each node leaves, the leaves are thick and glossy, are drooping, blooming from June to October every year, and the flowers are pink.

Second, the reason why the leaves of Cymbidium are yellowing.

1. Fertilizing too much, exceeding the demand of the plant, the leaves will appear bright and uneven after fertilization, and then the roots will show yellow due to malnutrition after partial decay. So at this time should stop fertilizing, more watering, or rice basin to wash the roots, change the new soil is also a very good way. It can be seen that the spatial soil liquid concentration is very important.

2. The soil has not been turned over for a long time, and the soil has solidified when all the nutrients in the basin have been exhausted. The deficiency of the three most important elements, nitrogen, phosphorus and potassium, makes the leaves gradually turn yellow. At this time, the soil should be changed or fertile loam and fertile water should be replaced in time.

3. Cymbidium is a semi-shade flower, but it also needs light, so you should keep at least 4-5 hours of light every day. Otherwise, the leaves will turn yellow when the chlorophyll decreases. The best way is to put it under an indoor incandescent lamp or on a balcony.

4. the air permeability and water permeability of basin soil are not good, which leads to long-term stagnant water and difficulty in root respiration, so the leaves turn yellow naturally. At this time, we should loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

Third, the solution to the yellowing of Cymbidium leaves.

1. The yellowing of the leaves of Cymbidium may be due to excessive fertilization, which exceeds the requirement of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

2. The yellowing of the leaves of Cymbidium may also be caused by not turning the pot and changing the soil for a long time. The various nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin. Fertile loam and fertile water should be replaced in time.

3. The yellowing of Cymbidium leaves may also be caused by lack of light. Although the orchid is a semi-negative flower, at least four hours of astigmatism should be seen every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

4. the air permeability and water permeability of basin soil are not good, which leads to long-term stagnant water and difficulty in root respiration, so the leaves turn yellow naturally. At this time, we should loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

In short, the cultivation of hanging orchid, we should grasp the hanging orchid like shade, often spray water, often fertilize, often change the basin of the four major maintenance points, I believe that breeding a beautiful hanging orchid is not a problem. In this way, the yellowing of orchid leaves can be avoided as far as possible.

The above is the relevant introduction of this article, I believe you have a simple understanding of this after reading it, if necessary, you can continue to pay attention to the No. 1 home network for more information.
