Corn seedlings grow slowly, what should I do?

By the time the three-leaf stage is reached, the nutrients stored in the seeds are depleted, which is called"Lactation", which is the first stage of the maize emergence stage. At this stage, soil moisture is the main factor affecting seedling emergence, so watering enough soil moisture plays a decisive role in maize yield.

<>In addition, the size of the seeds and the depth of sowing also have a lot to do with the strong seedlings, the larger the seeds, the more nutrients are stored, and the seedlings are more robust; The sowing depth directly affects the seedling emergence speed, the early emergence of seedlings is stronger than the emergence of seedlings later, according to the test, the sowing depth increases by centimeters, the emergence of seedlings is delayed by an average of one day, so the seedlings are weak. Corn is one of the main crops of farmers in China, with a wide range of planting, and is a relatively high-quality and high-yield cash food crop. I am also an authentic old farmer, our corn was sown in May, because I have been planting for many years, and I can say that I have a lot of experience, so my corn is growing very well.

However, for some farmers who have no experience and no technology, it is a headache.

As we all know, corn is generally planted in summer, when the temperature and ground temperature are relatively high, so corn is prone to water shortage, drought, and soil cracking. At this time, sufficient water is most needed at the seedling stage, and the lack of water will lead to slow growth at the seedling stage, and even the phenomenon of dead seedlings. Maize changed from autotrophic to heterotroph.

From the three-leaf stage to the joint stage, due to the incomplete development of roots and leaves, the absorption and production of nutrients are limited, and the growth of seedlings is slow, which is mainly manifested in root and leaf growth and stem node differentiation.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

1.It may be due to lack of water. Observe the field situation from time to time, and replenish water in time when encountering high temperature and drought, because corn is also a relatively drought-tolerant crop, so ensure that the soil is dry and wet, and water the water frequently to promote root absorption.

2.It may be that there is a lack of nutrients. It can be used in combination with water and fertilizer, spread around the root system of the plant, and can also be used in combination with foliar fertilizer if the leaf area is large. Nitrogen fertilizer is the main fertilizer, supplemented by trace element fertilizer.

3.It could be a pest or disease problem. This needs to be prevented in advance, early detection is better, the use of some preventive water or powder spraying plants, increase the probability of its pests and diseases, and scientific use of water and fertilizer, increase plant resistance. For specific chemicals, please consult your local agricultural material store.

Proper fertilization to ensure soil fertility, pay attention to the management of soil fertilizer and water, strengthen the elimination of pests and diseases, properly loosen the soil, corn seedling stage need to pay attention to fertilizer and water management, and carry out tillage to break the compaction.

This problem can be solved by turning the soil, spraying the nutrient solution, spraying pesticides, spraying insecticides and watering.

If the corn seedlings are weak, we must first find the cause, and then remedy it according to the cause, do not blindly remedy it, such as the weak seedlings caused by underground pests, but want to remedy it through top dressing, which is obviously not possible.

In fact, you can also apply a certain amount of fertilizer to this corn seedling, most of which are watered after supplementing nutrients, which can also increase growth.

You can go to participate in some corresponding fertilizers, and apply fertilizer every morning, which is conducive to its absorption, and it can be rejuvenated soon.

You can water them more and fertilize them more often, so that they can be well remedied, and they will grow well.

The growth of corn seedlings needs the uniform application of fertilizer, and at the same time, trace elements can not be lacking, timely top dressing, timely supplemental nutrition, top dressing urea 20 kg per mu when corn seedlings 6 7 leaves, and foliar fertilizer can be applied with potassium dihydrogen phosphate when 10 corn leaves. The weak growth of corn seedlings may be due to excessive pesticide spraying in the early stage, especially excessive spraying of herbicides, which affects the growth of corn seedlings, and can be sprayed with gibberellin mixed with water to promote the growth and development of corn seedling stems. Weeds, diseases and pests will also affect the growth of corn seedlings, and we should pay attention to cultivating and weeding during the growth of corn seedlings to reduce the absorption of nutrients by weeds to corn seedlings.

At the same time, it prevents the occurrence of insect pests. The slow growth of corn seedlings may lead to a delay in corn earing and maturation, which can affect the yield of corn. Therefore, maintaining the growth of maize seedlings plays a key role in improving maize yield.

Corn seedlings grow slowly, may be insufficient nutrients, insufficient water, low temperature or disease caused, when cultivating corn seedlings, you need to apply base fertilizer in the soil first, the cultivation time should not be too early, it is best to wait until the temperature is stable before planting, there are diseases to be prevented and controlled in time, so that corn seedlings can grow rapidly.

1. Insufficient nutrients

The growth of corn seedlings needs sufficient nutrients, if the nutrients are insufficient, then it will grow slowly, so when planting corn, it is necessary to apply some substrate mu fertilizer in the soil to improve the fertility of the soil, so that the corn seedlings can grow vigorously.

2. Insufficient moisture

The climate is too dry, the moisture in the soil is insufficient, then the corn seedlings will grow slowly because of lack of water, this phenomenon occurs, it is necessary to water the corn seedlings in an appropriate amount, keep the soil slightly moist is the most appropriate, pay attention not to water too much, otherwise the corn seedlings may grow.

3. The temperature is too low

Corn seedlings like to grow in a warm environment, if the temperature is too low, it will grow slowly, so the planting time of corn should not be too early, generally in the spring 4-5 months is the most suitable for planting, the temperature at this time gradually rises, corn seedlings can grow and develop quickly after planting.

4. Caused by disease

The slow growth of rice seedlings may be caused by disease, because the disease will hinder the growth of corn seedlings, if the situation is serious, corn seedlings may also appear wilting, at this time it is necessary to use fungicides to spray corn seedlings, so that it can recover its vitality.

Corn seedling stage is the most active period of underground pests, such as grubs, mole crickets, ground tigers, etc., in the underground live field, gnawing on the roots of corn seedlings, hindering growth and development, resulting in rotten roots and dead seedlings.

At present, the corn planting in the northern region of our country has basically come to an end, and now the corn seedlings have come out with several leaves, but the growth is slow, and the leaves still show signs of beating.

It stands to reason that now should be the peak time of corn, so let's analyze the specific reasons for the slow growth of corn seedlings.

First, consider the cause of water shortage

During this time, the temperature here is relatively high, and there is basically no rainThe ground is relatively dry, and the soil is compacted, which will affect the normal growth of corn seedlings, resulting in slow growth of corn seedlings.

Second, consider that it is the cause of the lack of fertilizerto support the normal development of seedlings.

If the corn seedling grows slowly, it may be that the nutrients consumed exceed its nutrient supply, and the metabolism cannot be normalized, causing the problem.

Third, consider the cause of pests and diseases

The corn seedling stage is the most active period for underground pestsLike grubs, mole crickets, ground tigers, etc., operate underground, gnawing on the roots of corn seedlings, hindering growth and development, will lead to rotten roots and dead seedlings.

In addition, there are too many weeds in the corn field, which will compete for nutrients; It is also possible that it is affected by herbicides, and corn seedlings are too dense and so on are the reasons for the slow growth of corn seedlings.

If the land is found to be dry and compacted, it is necessary to water it in time to ensure that the soil is moist and old。Corn is a drought-tolerant crop, as long as the soil is moist, it can ensure the normal growth of corn seedlings and promote metabolism.

Apply fertilizer at the right time。Corn is a fertilizer-loving crop, and only when the supply of nutrients meets the demand, corn can grow normally and lay the foundation for increasing income and yielding.

Before sowing, it is necessary to mix seeds with medicine to prevent the invasion of underground pests。Prevent in advance, spray preventive water and powder to reduce the occurrence of pests and diseases. If pests and diseases are found, they should be treated in time to minimize the loss.

Finally, weeds found in the corn field should be removed in time, pay attention to the plant spacing, and spray the drug in strict accordance with the required proportion, not excessive! Of course, there may be other reasons, and we need to solve the problem according to the actual situation.

There are many reasons for the slow growth of corn seedlings, which can be that the nutrients are not replenished in place, and the water is not sufficient, resulting in the soil being too dry. The temperature is not suitable, because corn seedlings themselves prefer to grow in a warmer environment. If corn seedlings are always given and placed in a low temperature environment, the growth of corn seedlings will be inhibited.

And during the growth of corn seedlings, they must be dewormed, otherwise they will be attacked by diseases and insects, and the corn seedlings will grow slowly. <>

If in the process of planting corn seedlings, the climate is in a relatively dry state. In this way, it will lead to a large loss of water in the soil, which will also affect the growth of corn seedlings. At this time, you can regularly water the corn seedlings, but be sure to control the amount of water.

Not too much and not too little, try to keep the corn seedlings, the soil in which they grow, and keep them moist at all times. <>

If you want corn seedlings to grow strongly, then during the growth period, you need to supplement enough nutrients. If nutrients are not sufficient, or if corn seedlings are malnourished, they can grow very slowly. Therefore, before planting corn seedlings, be sure to apply some basal fertilizer in the soil.

This improves the fertility of the soil and promotes the growth of corn seedlings. Moreover, most corn seedlings like to grow vigorously in a warm environment. <>

Once the temperature is too low, it will inhibit the growth of corn seedlings, and when planting corn seedlings, it is important to choose the right time. In general, it is very suitable to plant corn seedlings from April to May. Because at this time, the temperature has warmed up rapidly, and at this time, the maturity rate of corn planting will be particularly high.

And during the planting of corn seedlings, it is necessary to deworm regularly. Prevent corn seedlings from being attacked by pests and diseases, because after being attacked by pests and diseases, it will lead to a large amount of destruction of nutrients in corn seedlings. There will also be slow growth, so spray some drugs appropriately to kill insects.

It may be caused by insufficient nutrients, or insufficient water, or it may be caused by disease problems, and it is necessary to ensure the growth cycle of corn.

It may be that the moisture is not enough, it may be that the outside temperature is very low, or it may be that there is a problem with the sowing time, or it may be that the seeds are not good enough.

Oxygen is insufficient, moisture is insufficient, corn seedlings themselves prefer a warmer environment, the temperature is too low, infected with the virus.
