It s been half a month since the mustard greens were transplanted, why are the leaves still yellow?

Mustard greens are a very common vegetable in life, especially in winter, and many families will hoard a lot of mustard greens for the winter. Many families will choose to transplant mustard greens, but the leaves are easy to turn yellow after transplanting. These are related to the temperature and soil in which the mustard is grown.

Mustard greens are a cold food that is generally grown before the onset of winter. Therefore, it is necessary to pay attention to the temperature control during the planting process. Mustard greens cannot grow when the temperature is too high, and the temperature rises and the leaves of the mustard will turn yellow and gradually become soft and dry.

Pay attention to changes in temperature in mustard growing. In the case of too high or too low temperature, the leaves of mustard greens are unable to absorb water, and the growth process is restricted. Therefore, it is easy to turn yellow after transplanting.

In the case of too high temperature, it is necessary to replenish water for mustard seedlings in time. In addition, the growth rate of mustard is fast, in the case of transplanting, we must pay attention to the distance between mustard seedlings, so as to facilitate the extension of branches and leaves during the subsequent growth of mustard. In the process of transplanting mustard seedlings, it is necessary to select robust seedlings and sieve out mustard greens with dwarf and dry leaves.

On the other hand, the root system of mustard greens is relatively weak. When choosing for transplanting, it is necessary to choose loose soil, which can promote the growth of mustard and the root system can extend downward. Hard soil can make it difficult for the root system of mustard to absorb nutrients, leading to malnutrition and yellowing of leaves.

After transplanting, mustard greens will grow rapidly, and more nutrients are needed at this time, so vegetable farmers must fertilize in time. The root absorption capacity of mustard is not strong, and a small amount of fertilizer is needed to control the fertilizer concentration when fertilizing.

Pests and diseases are also a major cause of yellowing of mustard leaves. Mustard greens grown in the home are susceptible to pests and diseases. These pests bite the leaves of the mustard greens, causing the leaves to become more hollow, unable to absorb nutrients, and stop growing, causing the leaves to turn yellow.

At this time, we must pay attention to the appropriate use of pesticides for prevention and control, so as not to reduce the yield of mustard greens.

The reason why the leaves are still yellow is because his nutrients are insufficient, he lacks water, and he does not get relatively sufficient light conditions.

It may be that the fertilization is not enough, or the water is too little, or it may be that the soil is not suitable, the pH is not suitable, or the temperature is not suitable.

I think it may be that the seedlings are too fragile and have caused some damage to them in the process of transplanting, or they have not been watered properly and the climate is not suitable.

Mustard is a cold-tolerant crop, must be planted in winter to adapt to the climate, if not suitable for the climate and environment of the planting, not only can not grow, and the weather temperature rises, the mustard plant will slowly wither, and even die. When applying top dressing to mustard greens, if there is rot human and animal manure and urine, and then apply an appropriate amount of urea fertilizer to water the mustard greens, the mustard leaves will soon return to green. For friends who don't have farm fertilizer at home, it is also okay to apply urea fertilizer directly with the water.

<> mustard seedlings are sown and emerge, the growth rate is very fast, when the mustard seedlings grow a true leaf, the appropriate seedlings are expanded and the weak seedlings and tall seedlings are pulled out, so as to facilitate the vigorous growth of mustard seedlings and facilitate transplanting. Mustard greens prefer to grow in cooler temperatures, with the best temperature for growing being 15 20. When the temperature is lower than 15, the ability of mustard roots to absorb water decreases, and the growth is restricted, so after transplanting, the regreening is slower and even wilts.

One of the most famous mustard greens is the snow mushroom, which is a variant of mustard greens, but it is still a type of mustard greens. In many provinces, mustard greens are put in breakfast in breakfast shops, the most typical is the hot dry noodles and rice noodles in Hubei and Hunan, and the guests like to put pickles in the snow mushroom. As we all know, experienced vegetable farmers generally choose to transplant vegetable seedlings in the evening.

Pick up the mustard seedlings to be transplanted, then dig a nest in the place where the seedlings are missing, transplant the mustard seedlings into it, cultivate the soil, and then water the bottom of the foot.

First of all, we consider whether the seedbed is too dry and not watered in time, resulting in a lack of water in the roots of the transplanted shepherd's cabbage, resulting in the yellowing of the shepherd's cabbage. Only replanting. Generally, when transplanting vegetables, you must keep the soil moist for the first few days, and it should not be dry.

After the mustard transplanting needs to be replenished in time, with a cycle of 2-3 days according to the actual growth of mustard water, the principle of irrigation is "light before and heavy after", that is, in the early stage of mustard growth root system is weak, mainly light irrigation, the later root system is developed, and the water required will also increase.

It may be that the leaves are still very yellow because they are not fully nourished and the branches and leaves are not pruned.

Because the mustard greens after transplanting are very nutritious. At this time, apply more fertilizer to the mustard greens. Improve their growth.

Because the mustard has not yet fully adapted to this soil, it takes longer to adapt to this soil, and only when it is truly adapted to this soil will the leaves turn green.

This is because celery lacks a lot of nutrients and doesn't get particularly good sun exposure.

It's because your temperature isn't up to par and you don't have regular ventilation that mustard greens can be malnourished.

Because there are no nutrients, the leaves of mustard greens will turn yellow when they do not get enough nutrients.

Mustard greens, rich in vitamins, nutritious and have certain medicinal properties, are still loved by us in the form of fresh fish, dried plum vegetables and pickled cabbage. And it has strong adaptability, low requirements for soil, few diseases, easy management methods, and high production. Mustard is a low-temperature tolerant crop, must be planted in winter to meet the climate, if not suitable for the climate and environment under the premise of planting, not only can not grow, and the temperature rises, mustard plants will gradually wither, so that it will die.

Fertilizer and water management methods: Fertilizer and water management methods have a very important relationship with the growth of mustard, we need to grasp the seedling condition of the soil and its temperature level, and effectively irrigate to maintain soil moisture. In the case of mustard growth, the nutrient intake is particularly large, therefore, the base fertilizer can not be less before planting mustard, and the lack of this stage is not conducive to the growth of mustard.

Everyone understands that it is good to do a good job in the promotion of base fertilizer before mustard transplanting, and the fertilization of mustard is not as important as base fertilizer. Growth management method: mustard in the case of growth, fertilizer as little as possible several times, the use of chemical fertilizer to achieve the limit value of the mustard to absorb the active ingredient of nutrients, can not be over-applied chemical fertilizer, in case of burning mustard, mustard can also turn yellow.

If you only apply fertilizer once, you will ignore it for the rest of the day, and the leaves of the mustard will turn yellow. After mustard planting and germination, the growth rate is very fast, when the mustard seedlings emerge a true leaf, the seedling expansion interval is moderately supplemented, and the weak seedlings and high-legged seedlings are pulled out, so as to facilitate the healthy growth of mustard seedlings and transplanting. When the seedlings emerge two to three leaves, they can be transplanted, because the mustard root is later than the leaves, especially the fine roots are not developed, so the transplanting should be carried out with soil balls, in order to maintain the rhizome and help slow the roots.

Before transplanting, the seedlings should be watered thoroughly, and when the water is sufficient to infiltrate and the soil is slightly wet, choose to transplant with tree soil balls in the afternoon. The land should also be kept moist at all times and watered immediately after the budding period of transplanting. Too much base fertilizer will "burn the seedlings" yellow, too little will be "psychological distortion" yellow seedlings, should be based on the transplanting land soil fertilizer efficiency, moderate use of organic fertilizer can.

After the root is slowed back to green, mustard can be fertilized once every time the soil is loosened before ridge sealing, and the content and use of chemical fertilizer are about 20kg per mu, and the key is sodium chloride and urea solution. When fertilizing, it is evenly applied in the ditch, and the mustard root can not directly contact the chemical fertilizer to prevent the chemical fertilizer from burning the mustard rhizome.

Mustard greens prefer to grow at cool temperatures, and the optimal ambient temperature for growing is 15 to 20. When the ambient temperature is less than 15, the ability of mustard rhizomes to absorb water is reduced, and the growth is restricted, so after transplanting, the regreening is relatively slow, and even withering occurs. The rhizomes of mustard are underdeveloped, and the ability to digest and absorb fertilizer and water after transplanting is weak.

Therefore, mustard seedlings should be fertilized once before transplanting, and it is best to fertilize 5 to 7 days earlier. In this way, after changing the natural environment of growth, mustard seedlings can help them successfully survive the slow seedling stage with the nutrients they carry.

It may be because you didn't water it in time and you didn't top dressing, so this happens; Be sure to water and top dressing more, be sure to remove weeds regularly, and spray pesticides regularly, so that the leaves will not be yellow.

It may be due to pests and diseases, or because of insufficient watering, or because the mustard greens have not yet adapted to the new environment; To water more, you can apply fertilizer properly and spray some pesticides.

This may be due to the fact that the quality of the soil is not particularly good, or it may be due to the fact that it has been exposed to light for too long. That's why it causes yellowing. You can choose to water it all the time at night, and you should also water it frequently after transplanting, so as to ensure moisture and nutrition.

It can be caused by malnutrition, or it can be due to insufficient light and low ambient temperature; It is necessary to water the top dressing in time to ensure that the vegetables can get nutrients.

The vegetables that need to be transplanted can generally be transplanted when the seedlings grow to about 10-15 cm, and the conditions are suitable for the germination of vegetable seeds, the growth is fast, and the fertilizer is also needed. Some people think that if you want to transplant anyway, it will be no less than the additional cost after transplanting in those days, and I know that vegetable seedlings are easy to turn yellow after transplanting. Because the seedling machine does not absorb enough fertilizer, it does not grow well enough.

After that, it is necessary to top dressing well. The vegetable saplings of this period were not large. Mainly long roots, stems and leaves, with rotten manure and other farm manure top dressing.

If you don't have farmyard fertilizer, you can choose to use urea. The next time you plant a sapling, you should let the vegetable sapling grow well before transplanting, and if you don't want to top fertilize after germination, it is best to give it enough base fertilizer before sowing. It is better to choose farmhouse fertilizer.

Farm manure has a long effect.

Plant-fed vegetables usually take 3-5 days to take root in new soil. These days, the fertilizer is worse than usual. Some people believe that vegetable seedlings can not take root anyway, can not absorb more fertilizer nutrients, do not apply fertilizer after transplantation, vegetable seedlings are easy to yellow after transplantation, malnutrition.

Let us analyze the main reasons why vegetable leaves always turn yellow. Usually the causes of yellowing of vegetable leaves are: improper fertilizer (such as insufficient trace element fertilizer), improper watering (insufficient water or too much water leads to nutrient loss), the surrounding temperature is too low to hinder the nutrient absorption of vegetable plants, and the nutrient synthesis of vegetable plants is hindered due to insufficient light.

According to the above analysis, most of the causes of yellowing of vegetable leaves are related to nutritional deficiencies, so the main measure to prevent yellowing of vegetable leaves is to ensure the nutrition of vegetables**. That said, fertilizing is very important in the process.

In the countryside, when growing vegetables in the vegetable garden or on the balcony of our own home, we pay the most attention to fertilization is the foundation. Rarely go to the middle top dressing. Even if there is a problem, there are many people who blindly look for solutions and abuse chemical fertilizers and pesticides.

Here today. I will correctly solve the method of yellowing the leaves of vegetables. The above analysis showed that the yellowing of vegetable leaves was mainly caused by nutrient deficiencies.

This is what we often call deficiency.

Depending on the vegetables, trace elements such as magnesium deficiency and iron deficiency will be produced, and depending on the degree, the leaves will turn yellow in different parts. The lack of magnesium fertilizer in vegetables will make the paddle leaves (middle and lower leaves) of vegetables yellow, and the lack of iron fertilizer in vegetable plants will make the young leaves of vegetables yellow (the leaves of the leaf center) and the leaf veins yellow. With this symptom, we can all spray foliar fertilizer on vegetables and solve this problem very well.

Foliar fertilizer is mostly used at night when there is no wind. At this time, the temperature is not high, sprinkle uniform foliar fertilizer, which can be well absorbed by vegetable crops, and the temperature is too high to produce resistance to vegetables.

One condition may be that you are sick and should be treated aggressively. Another situation may be that there is not enough water and not enough fertilizer.

It may be that the shepherd's cabbage lacks a certain nutrient, you can fertilize it appropriately or add some trace elements to the shepherd's cabbage, otherwise the cabbage will be easy to die if the leaves keep yellow.

1. The roots are not awakened, and after the mustard is transplanted, the roots are not active, resulting in the whole mustard not absorbing nutrients and water, which is manifested as yellowing and necrosis of the leaves. 2. After transplanting, there is no timely watering, and it needs to be watered after transplanting, especially if there will be a big sun later, it must be watered to prevent the seedlings from being sunburned. 3. Lack of nutrition, after the mustard is transplanted, the vegetable leaves have also risen, but the vegetable leaves have been yellow, and the root cause is malnutrition, which is the same as our malnutrition.

If the mustard you planted has raised its head, but the leaves are yellow, then most of them are due to this bowup.
