Carrot seedlings emerge slowly and unevenly, how to solve this problem?

Carrots at the seedling stage are brittle and cannot tolerate excessive nutrients. As long as sufficient basal fertilizer is applied, there is no need to deliberately supplement their seedlings with nutrients. As the carrot seedlings grow, they will become very neat.

In order for the seedlings to grow neatly, we should choose some seeds of good varieties and then dispose of the hairs on them. After planting, such seeds can be in better contact with the soil and absorb more water, which is of great benefit to the germination of seeds. When sowing, it is best to sow seeds according to certain rules, which can be row by row or one by one, so that each seed has enough space to absorb nutrients, and the seedlings that grow will be more neat.

Their fruits are highly nutritious and have a relatively high demand for nutrients. So apply good basal fertilizer so that they have a good growing condition, and they will grow bigger. You can supplement the soil with nutrients before planting, and then plant carrots in it to allow the seedlings to absorb enough nutrients to promote the development of the seedlings and grow more neatly after they emerge.

After they are underground, they neglect management, resulting in stiff soil in the field, which has a great impact on seedlings and seriously leads to the phenomenon of no seedlings. If the soil is found to be hard, it is necessary to plow and loosen the soil in time to provide a good growth environment for the seedlings, which will effectively avoid the phenomenon of uneven seedlings. With careful management, carrot seedlings will become more neat.

Because carrot flowering and pollination are greatly affected by the climate, it is easy to form embryoless or embryonic seeds. Moreover, the embryo of carrot is very small, the growth potential is weak, and a large amount of seed nutrients are consumed during the germination period, resulting in poor seedling emergence ability. The summer sowing climate is hot, the evaporation is large, the soil temperature is high, and it is easy to dry; During spring sowing, the ground temperature is low and the wind is dry, making it difficult to maintain long-term conditions suitable for the germination and emergence of carrot seeds.

Under good germination conditions, the normal germination rate is only about 70%. If the germination conditions are not good, the germination rate can sometimes drop to 20%. Therefore, creating good germination conditions is a necessary cultivation measure to ensure the neatness and integrity of seedlings.

Carrot planting must choose a deep soil layer, loose soil, good drainage, rich organic matter sandy loam or sub-loam soil, deep ploughing and fine raking, so that the topsoil is delicate.

Top dressing for carrots. It may be that the soil is too poor, and trying top dressing can make the carrots grow better.

Choose superior species. Handle the seeds. Soak seeds to promote germination. Fine land preparation. Also pay attention to watering after sowing to keep the soil moist.

This needs to be supplemented with a certain amount of nutrition, and it is best to go to the local agricultural station and ask the relevant personnel to solve it, otherwise it is likely to cause a big problem.

You can sprinkle some auxin and chemical fertilizer to give enough nutrients, and you can wait for its strong growth.

The first thing to do is to pick some good quality seeds and sprinkle them on the ground, as sparsely as possible, because carrots need a lot of land space to grow. Then carry out selective breeding, select some good carrot seedlings, and then replant them into the ground, at this time the carrot seedlings are neat and grow fast.

Carrot Habits:

Carotene is known as "little ginseng.""It is rich in sugars, fats, volatile oils, carotene, vitamin B1, vitamin B2, anthocyanins, calcium, iron and other nutrients. It has the effects of strengthening the spleen and stomach, nourishing the liver and brightening the eyes, clearing heat and detoxifying, smoothing the qi and relieving cough.

Carrot is a deep-rooted vegetable, requiring a deep, fertile, well-drained sandy loam soil, such as the soil is too clayey, easy to produce disproportionate roots, cracked roots, if the soil is waterlogged will lead to rotten roots, the roots are mostly distributed in the soil layer of 20-90 cm. Carrots prefer low temperatures. The growth temperature is 18 23, and the seedlings can tolerate short-term -3 -5 low.

Now that you know the habits of carrots, it's time to learn how to grow carrots, so let's start with a few points.

Sowing method: carrots are straight roots, so more direct seeding, less seedling transplanting. After the ground is thoroughly cleaned before sowing, it is necessary to turn it 35 cm deep and also dry the soil for sterilization.

Dry seed seeding can be pre-germination treatment, soak the seeds in cold water for 3 4 hours, wrap them in wet gauze after draining hail and dry them, put them in containers, moisturize and germinate them at 25 times, and you can sow seeds when 1 3 seeds are exposed. Carrots are generally sown in summer and autumn and harvested in autumn and winter. The best time to sow carrots is between the light and high heat, but it is best to sow carrots in spring, usually from late February to early March.

Light, water and fertilization:

Carrots are semi-hardy vegetables that prefer cold and cold growth. The appropriate temperature for seed germination is 20--25. The suitable temperature for seedling stage and leaf growth is 23--25.

The suitable temperature for fleshy root expansion is 13--20. , 4 below will stop growing; Carrots like to have enough light, and insufficient light will cause the petioles to be slender and the leaves to become smaller; Carrots are more drought-tolerant, i.e. they can keep the soil moist. However, when the fleshy root swells, it is necessary to ensure sufficient moisture**, if the moisture is insufficient, the fleshy roots will be small and rough.

Watering should be even, if the dry and wet are uneven, it will lead to root cracking; Carrots do not need much fertilizer in the early stage of growth, so on the basis of applying sufficient basal fertilizer, top dressing in the middle and late stages 2 3 times, top dressing can be combined with watering for the source.

Finally, wait until the carrot leaves are yellow-green, the outer leaves are slightly yellow, and the roots are slightly exposed to the soil.

It may be that the temperature is not particularly high, there may be a lack of water, a lack of fertilizer, and it may be a problem with the Heyan variety. Ants do.

You should spray some growth-promoting agents appropriately, so that there will be a very good emergence of seedlings, and the growth rate will be a little faster.

Pay attention to the condition of the soil, pay attention to the choice of varieties, pay attention to watering, need to pay attention to light, and the soil needs to be sunburned.

Then drain the seeds, wrap them in damp gauze, and place them in a container to moisten them at 25 hours. After soaking, seedlings can emerge after sowing for 5-7 days, and seedlings can emerge after 10-15 days for live broadcasting. The small prickly hairs on the skin of carrot seeds can block water absorption and hinder the seed and soil connection, the shell absorbs water slowly and is difficult to penetrate, so it can artificially rub off the resistance of these small hairs, so that the seeds and the soil are in good contact, the water infiltration speed is fast, and the seed germination is also about to be based on the soil moisture in the field.

The consumption of carrots is still very large, and growing carrots is profitable. However, people who grow carrots know that how to ensure early emergence and how to cultivate cherry seedlings are the most critical skills for high and stable yield of carrots. Fine rake leveling, after stepping on the solid, so that in order to make the ground really flat, conducive to irrigation evenly, sprinkle seeds, and then rake vertically and horizontally, in order to mix the seeds and soil, and then step on the firm, water thoroughly, cover it with a straw curtain or plastic sheet, and wait for a few days after germination, remove it in the evening, <>

Carrot seeds absorb water slowly, germinate late, germination sowing can emerge early, in the first 7-10 days of sowing, the seeds that rub off the prickly hairs are soaked in water for about 40 hours for 2 hours, and after rinsing at 20-25 temperatures, maintain a suitable humidity for germination and planting carrots all know, carrot seeds cortex is thicker, seedlings emerge slowly, and there will be some seedlings early after planting, and some of the seedlings are irregular. The carrots produced are uneven in size, which seriously affects the yield of carrots.

The peel of carrot seeds is thick, there are prickly hairs on it, poor water absorption, slow hair and slow empty budding, and the seed embryo is small, the growth is weak, in order to achieve early seedling, early seedlings must master the sowing technology. When planting carrots, it is best to choose well-rotted farmhouse fertilizer, supplemented by compound fertilizer with high potassium content. The ground must be turned deep to achieve no root stubble and no stubble.

Lay a good foundation for the early emergence of carrots and early seedlings.

The first thing to do is to choose the seeds. The quality of the seed code, germination rate and germination potential are directly related to whether the carrot can emerge after sowing, and it is also related to the early emergence of seedlings and the emergence of full seedlings. When buying seeds, try to choose treated light seeds, if it is a hairy seed, first rub off the thorn hairs on the seeds when sowing, so that the seeds are closely connected with the soil, absorb more water, and facilitate germination.

To soak the seeds before sowing, the Fang Chi Yunming method is to soak the seeds in cold water for 3-4 hours, then drain the seeds, wrap them in wet gauze, and then put them in a container to moisten them at 25 hours. After soaking, seedlings can emerge after sowing for 5-7 days, and seedlings can emerge after 10-15 days for live broadcasting.

First of all, you should learn professional planting techniques, and keep the soil fertile when planting, and you should also do watering and fertilizing in time, and you should also pay attention to insect pests, spray some pesticides in time to ensure sufficient light.

When planting carrots, in addition to ensuring that the environment is pollution-free, we need to choose fertile soil, loose soil, convenient drainage and irrigation, neutral or slightly acidic sandy loam or loam, the first crop is best non-umbelliferous vegetables, such as cabbage, cucumbers, tomatoes, onions, garlic, etc.

Carrots are widely cultivated in China and are a very popular vegetable. It can be eaten raw or stir-fried, making it a delicious dish. Carrots are rich in vitamin C and are widely distributed throughout China.

However, many friends will find that the emergence rate of carrot seedlings is very low when planting. Therefore, Xiaoyisou brings you a way to improve the emergence rate of carrots today. Let's take a look!

1. Select superior species.

The structure of carrot seeds is complex, and the germination rate of the seeds will be reduced due to environmental factors due to the hard texture, poor permeability, small embryos, and weak bulldozing ability of carrot seeds. And if the seeds are stored for too long, the germination rate will be lower, so be sure to maintain the freshness of the seeds before planting. We can discern the quality of the seeds by smelling the smell and observing the color.

2. Treat the seeds.

When choosing seeds, it is best to choose seeds that have been treated. If there are a lot of bristles on the surface of the seed, then wipe them off in time. Increasing the contact area between seeds and soil and enhancing the nutrients and water absorption capacity of seeds can promote seed germination.

Before sowing, the seeds should be exposed to the sun for two days to improve the vigor of the seeds, promote the germination of the seeds, and enhance the germination ability.

3. Soak seeds to promote germination.

Normally, carrot seeds are seeded live to increase the amount of sowing and increase the number of carrot seedlings. Therefore, it is necessary to soak the seeds properly when sowing to accelerate germination and improve the germination rate of seeds. First, soak the treated seeds in warm water at about 45 degrees for about 2 hours, and then wrap the seeds in a damp cloth.

Then put it at a temperature of about 22-24 degrees to accelerate germination, and after about 80% of the seeds turn white in about three days, you can start sowing.

4. Fine land preparation.

When planting, choose deep, soft, and fertile sandy soil for planting. After selecting the land, it is necessary to carry out deep ploughing and land preparation, and the depth of the cultivated land is about 26-29cm. Then, make a furrow rake and apply sufficient base fertilizer according to the planting area, the base fertilizer is mainly rotting farmhouse fertilizer, supplemented by compound fertilizer.

It is best to crush the soil when sowing to prevent soil compaction, improve the permeability of the soil, promote seed germination, and improve the emergence rate.

5. Precautions.

Water and drain the water before preparing the land, and then sow the seeds when the soil moisture is good. After sowing, pay attention to watering and keep the soil moist. When sowing, a small amount of green vegetable seeds can be mixed into the seeds, and the characteristics of green vegetables with strong growth ability can be used for shading.

After the carrot seedlings are unearthed, the greens are basically ripe and can be harvested for marketing. It not only improves the planting efficiency, but also improves the seedling emergence rate and land utilization rate of carrots.

After sowing, it is necessary to properly cover the mulch film and vegetables to improve the thermal insulation and moisture retention ability of the soil, prevent the rain from washing the soil and causing soil compaction, so that the seeds are blocked and break the soil. After the emergence of seedlings, we should do a good job of weeding to prevent weeds from robbing the seedlings of nutrition, resulting in a lack of weeds, and improving the survival rate of carrot seedlings. That's all for today.

Carrot emergence time.

After sowing, cover the carrots with soil and suppress. After seven to ten days, the seedlings can sprout. If you want it to emerge on schedule, you must pay attention to the planting method and the usual maintenance management.

When planting, it is necessary to use suitable soil to ensure that the soil is fertile, loose and well drained. After planting, it is necessary to moisturize frequently and apply thin fertilizer frequently.

Carrot sowing time and method.

Carrots are suitable for sowing in spring and autumn. If the best time to plant in spring is from late January to early February, spring can also be sown from mid-March to April, and autumn carrots are best planted around July.

2. Seed treatment:

Carrots should be dried before planting, then soaked in warm water for about 3-4 hours, covered with clean gauze, and placed in an environment with a temperature of about 20-25 for germination. It's white in about a month.

3. Planting and sowing:

Prepare loose and fertile sandy loam soil rich in organic matter, put the seedlings into the sandy soil, keep the spacing at about 25cm, add an appropriate amount of well-rotted organic fertilizer, pour water to loosen the soil, fully mix nutrients with the soil, and strengthen the management of bright water and fertilizer.

How to manage carrots after they emerge.

1. Watering in time:

After the emergence of carrots, the root system is very shallow, the growth is fragile, and the water requirement is relatively small, so it is necessary to water less and frequently, and not too much water at a time, so as not to accumulate a lot of water in the soil, otherwise it is easy to lead to root rot and affect the growth of radish.

2. Reasonable top dressing:

After the carrot does not emerge, do not rush to top dressing. After emergence, watering and top dressing are combined. 10-15 kg of urea and 10 kg of potassium sulfate can be applied per mu to promote the growth of seedling leaves.

3. And time seedlings:

Carrot seedlings should be seedlings in time for seedlings. Generally, the first defoliation can be done at the time of the first true leaf. Weak seedlings, stunted growth, and pests and diseases are pulled out to leave healthy and robust seedlings.
