Yellowing of cabbage leaves and wilting is a pathology.

Yellowing and wilting of cabbage leaves may be due to drought and lack of water, or wilt.

It is a disease of Chinese cabbage in the bulbous stage.

The outer leaves grow normally, while the inner part of the leaf bulb becomes dry and yellowed from the leaf margin, and the mesophyll is translucent and dry paper-like, and dry heartburn occurs.

Chinese cabbage is not resistant to storage, the quality declines, and it loses its edible value in serious cases.

Too little watering, bacterial disease.

Normally, you can cut off the dead leaves.

The yellowing of the cabbage leaves may be due to disease, drought, lack of water or wilting.

It's better not to eat it.

Reasons for the yellowing of cabbage leavesThere are actually five main reasons for the yellowing of cabbage leaves. The first is that there is too much water in the field, and the soil is not permeable and poorly drained, which causes the cabbage roots to rot, and the cabbage leaves will lose their luster, fade green, and gradually shrink. The second is that excessive fertilization occurs and fertilizer damage occurs, resulting in fat yellow cabbage leaves.

The third is the lack of water in the field, no timely replenishment of water, the cabbage appears dehydrated, and the leaves gradually age and turn yellow. The fourth is that due to the lack of fertilizer, the effects are not good, resulting in no vitality of the leaves, but the color is not really yellow, which can be described as thin yellow muscles. The fifth is due to the alkaline soil or water quality, which has an impact on the growth of cabbage.

The last thing we should pay attention to is that the cabbage leaves are yellow, and it may also be caused by pests and diseases.

This situation indicates that the cabbage already has germs and can no longer be eaten.

Cabbage is soft rot, yellow leaves are removed from rot, and they can be eaten by drying them.

The yellowing of Chinese cabbage leaves can be caused by lack of fertilizer, excessive soil moisture, insufficient moisture, or insect infestation. Just get rid of the yellowing and wilting areas.

I love to eat cabbage-stuffed dumplings, I can't do it well, this time I learned to operate, go try to make it once, see if it can be successful, good luck to me!

The yellowing of the heart leaves is considered for the following reasons: 1. High pesticide concentration or improper use of hormone leaf fertilizer. 2. The whitening and yellowing of the heart leaves is mainly due to zinc and iron deficiency. 3. Soil drought, sudden watering of cold water to fry roots, high concentration of water and fertilizer, soil pollution, poor environment and other factors caused by root damage, will also cause the heart leaves to turn yellow.

Summary. Hello, dear. The edges of cabbage leaves are dry and dry because they are infected with soft rot, and copper preparations can be sprayed once a week, twice in a row, or 100 times Bordeaux solution, once in 10 days, two or three times in a row, and management should be strengthened in the later stage.

The management method is as follows: appropriate watering: water evaporates quickly in a high temperature environment, watering in time, but the amount of water should be controlled, and the soil can be slightly wet.

Reasonable fertilization: apply diluted fertilizer or well-rotted fertilizer during the growing season, and apply less thin fertilizer.

Hello, Heng Leak Qingqin. The edges of cabbage leaves are dry and dry because they are infected with soft rot, and copper preparations can be sprayed once a week, twice in a row, or 100 times Bordeaux solution, once in 10 days, two or three times in a row, and management should be strengthened in the later stage. Here's how to manage it:

Appropriate watering: water evaporates quickly in a high temperature environment, so water in time, but the amount of water should be controlled, and the soil should be slightly wet. Proper fertilization:

Apply diluted fertilizer or rotted fertilizer in the previous growing season, and apply less fertilizer thinly.

The edge of cabbage leaves is dry because of the infection of soft rot, long-term high temperature, dry and rapid drought environment, resulting in damage to the root system of cabbage, it is easy to be infected with bacteria, easy to lead to growth and rise this undesirable situation, it may also be caused by improper fertilization, the application of fertilizer is not rotten, fertilizer fermentation produces a lot of heat trapping, burns the root system, destroys the absorption capacity of the root system, and thus infects the disease. In this case, the copper preparation should be sprayed as soon as possible, once a week, twice in a row. It can also be sprayed with 500 times pentachloronitrobenzene solution or 100 times Bordeaux solution, and the drug is used once every 10 days, two or three times in a row, so as to avoid the dry and yellowing of the leaves.

The leaves are yellowish.

The original residue of cabbage leaves yellowing: 1. Lack of nutrients Potassium and magnesium deficiency in Chinese cabbage will cause yellowing of leaves. 2. Improper fertilization, such as the application of organic fertilizer is not fully decomposed, too much fertilizer or fertilizer is not evenly spread, etc.

It is easy to cause root damage and cause yellowing of leaves. 3. The soil is not suitable The soil is too dry, the soil is salinized or the soil is waterlogged, and the leaves of the cabbage are yellow. 4. Disease problems, such as yellow leaf disease.

The main manifestations are: the leaves begin to yellowish from the rosette to the early stage of the center, and fade and turn yellow between the veins of the old leaves. In severe cases, it will cause the Zhaochun plant to shrink or die.

Summary. Hello dear, what is the reason for the yellowing of cabbage leaves, there are generally 3 situations that will cause first, it is due to excessive watering that leads to soil waterlogging, soil permeability becomes poor, and the growth of cabbage roots is hindered, resulting in yellowing of leaves. The symptoms of cabbage are that the young leaves are dark yellow and dull, and the new leaves are shriveled.

Second, it is caused by excessive fertilization, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny but generally not stretched. 3. Caused by excessive soil drought, the new leaves of cabbage are normal, but the lower leaves gradually dry up and fall off and age.

Hello dear, what is the reason for the yellowing of cabbage leaves, there are generally 3 situations that will cause first, it is due to excessive watering that leads to soil waterlogging, and the soil is poor in terms of tardiness, and the growth of cabbage roots is hindered by trembling, resulting in yellowing of leaves. The symptoms of cabbage are that the young leaves are dark yellow and dull, and the new leaves are shriveled. Second, it is caused by excessive fertilization, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny but generally not stretched.

3. Caused by excessive drought in the soil, the new leaves of cabbage are normal, but the lower leaves seep into the mountain and gradually dry up and fall off and age.

Related information: How to prevent yellowing of cabbage leaves? (1) The sowing time of cabbage should not be too early, and it is best to avoid the high temperature and dry season; (2) Disinfect the seeds during sowing, and use 250-300 times of copper succinate fertilizer to soak the seeds for 30 minutes; (3) It is recommended to plant cabbage on the high ridge, and the ridge height is recommended to be 20-25 cm to promote the growth and development of the root system (4) Watering should be watered frequently with small water, reduce the ground temperature, avoid water accumulation, pay attention to the cultivation and hoeing, and keep the soil dry and wet.

5) If it has occurred, it can be treated with pesticides, and carbendazim, methyl thiobacterium, and spray irrigation can be used.

It's okay to eat, but it doesn't taste good. Yellowing of cabbage indicates a loss of chlorophyll and conversion to lutein. The cabbage begins to react with dehydration, and the vegetables begin to grow old, and the taste is not good, but it is not toxic and can be eaten.

The reasons for the yellowing of cabbage leaves may be:

One is yellow, that is, too much water causes the soil to accumulate water for a long time, poor air permeability and even some fibrous roots rot. It shows that the young leaves are dark yellow and dull, and the new shoots are shriveled.

The second is fat yellow, that is, fat, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny, but generally uneven and unstretched. You can sprinkle a layer of radish seeds and pull them out after a few days of emergence to consume nutrients.

The third is dry yellow, due to long-term lack of watering or dehydration, although the new leaves are normal in color, the lower leaves gradually dry up and fall off and age.
