Can you use urea for celery top dressing? How to do top dressing management for celery?

Celery is a vitamin, aromatic, rich, vitamin-rich and volatile aroma, people like to eat delicious fiber green leaves. There are two types of books and celery, and this celery has an elongated handle that is suitable for slowing down and softening. According to the color of the lobules, it is divided into green red eyes and white deficits.

White tension is small and easy to soften, ***, pony. I can't use urea for this statement, i.e. can't use urea for the celery growth cycle. It depends on experience and sweat, it will be better if it is integrated with science, and the small manure is already in the past, only water can be given, but seeing the phase is not good, <>

After dissolving urea in water, celery is not fast, but the leaves are also green. However, when urea is poured into water, it must keep the soil moist for consecutive days. If you see the soil, you can't let the soil dry, otherwise you can stick to the fertilizer on the blades.

Dilution will rust. Rotten and yellow. Now new varieties, new technologies are widely used in cultivation, more and more fertilizers are in the scientific formula, the application of urea is not easy to control, so most of them have a mixture of nitrogen, phosphorus, potassium fertilizer and soluble fat, celery growth needs organic matter, water, water and fertilizer soil, which is easily lacking in celery, which will lead to the hollowing phenomenon in celery.

Celery lacks nitrogen and phosphorus at all times, so the growth of celery plants is hindered so that the plants are not large and the leaves are aged. That is, nitrogen, phosphorus, and potassium are the three elements that celery grows.

The celery growing period has the main period of seedlings, the seedling stage, the vegetative growth period, and the fertilizer growth period is different in these three periods, so the fertilizer management is also different. About 15 to 20 days, watering, shallow dumping, keeping the soil moist continuously, lowering the temperature of the land, applying water manure appropriately. Watering at the seedling stage is not a consultation, celery will be prone to flare-ups, and when watering, nitrogen fertilizer can be applied appropriately.

This period is about ten to 15 days.

Nutritional growth Sheng Xu Ye Qi's growth began, and this period was the fastest growth in celery. It can be applied immediately, the second to the third time, if the soil is deficient in potassium and deficient in potassium. Celery, on the other hand, has a greater need for boron, and if the boar fat in the soil is too high or too low, and the soil is dry, celery absorbs boron powder pots that are inhibited, thus creating stem stalks.

Therefore, boar manure can be applied during the growing season.

There are a lot of sheds for cultivation here, and I think celery is the most important thing to improve the soil and prevent death. Celery is generally a heavy planting, with a large amount of acid-based fertilizers and chemical fertilizers, which leads to severe acidification of acidified soils, affecting root growth, root rot, and seedlings.

Celery should be fertilized with more nitrogen fertilizer, but urea should not be topdressed. Celery requires a lot of nitrogen fertilizer throughout the growing period, and top dressing should be dominated by ammonium bicarbonate. Do a small amount many times, generally need to top dressing 2-3 times.

However, it should be noted that celery should not be top-applied with urea, because the growth of celery is slow, the cellulose increases, the plant is easy to age, the quality is reduced, and it has a bitter taste when eaten.

It is best not to use urea when dressing celery, more nitrogen fertilizer should be applied, more nitrogen fertilizer should be applied during the growth process, and a small amount of fertilization method should be done many times, generally 2 to 3 times as well.

No. The growth of topdressing urea is slow, and the plant is easy to age. It has a bitter taste when eaten. Top dressing should be based on ammonium bicarbonate, and a small amount of top dressing should be done many times, and it is generally necessary to top dressing two to three times.

Because the way of fertilization is different or not scientific enough to produce fertilizer damage, which seriously reduces the growth and development of vegetables, reduces the yield and quality of vegetables, and pollutes the soil, of which celery is no exception, due to excessive fertilization and fertilizer damage, how to prevent it? Celery likes cold, more cold-tolerant, belongs to semi-cold-tolerant vegetables, seeds 4 begin to germinate, germination temperature 15 20, higher than 25 or lower than 15 germination rate to reduce or prolong germination time, but seedlings can tolerate -4 -5 low temperature. Therefore, before fertilization, it is necessary to strictly proportion, and carry out reasonable fertilization according to weather conditions and different seedling stages, and uphold the principle of "less diligent application, should be light and not thick".

The first is to water in time, be sure to keep it moist, not to make the soil too dry. It is not possible to over-control the water because of the control of the long seedling stage of celery, which is very easy to cause ammonia poisoning, so watering at the seedling stage can be combined with spraying strongin. The specific method is to dilute urea with water (pay attention to the dosage, the page will turn yellow after too much fertilization), and then spray it on the foliage of vegetables, which are suitable for vegetables that are not edible and have large leaves, such as cucumbers, kidney beans, pumpkins, etc.

In fact, you don't have to worry, celery absorbs the nutrients inside, and the dirt left on the celery will be washed away by rainwater, not to mention that it has to be washed over and over again when eating vegetables.

Too much fertilizer can't be absorbed and utilized by celery, resulting in waste. Therefore, in order to achieve a higher utilization rate of fertilizer, it is best to integrate water and fertilizer, which can also reduce the amount of fertilizer used and reduce costs. Top dressing must be timely.

In order to promote the growth of new roots and leaves, less fast-acting nitrogen fertilizer can be applied to raise seedlings, and 15 20 kg of ammonium sulfate per mu is applied to the ditch. Celery has a large water requirement in its life, is not drought tolerant, and requires sufficient water**, which can make celery fresh and tender, with developed roots and enhanced fertilizer absorption ability. If there is a lack of water during the growing season, it will cause the leaves to turn yellow, the stalks to age, and the hollowness is severe.

If it is planted on the ground, then the remedial point is not very significant, and there is an option to water heavily to allow urea to penetrate as much as possible deep into the ground.

Answer this question by me to answer, typing takes a little time, please be patient and wait for the whole growth stage of celery to grow more vigorously, so the demand for fertilizer is relatively large, especially for some nitrogen fertilizer demand, when we talk about supplementing nitrogen fertilizer, we generally think of using urea. But if you're growing celery, don't use urea when applying nitrogen fertilizer. Although the nitrogen content of urea in nitrogen fertilizer is relatively high and relatively cheap, after the celery generation applies urea, it will lead to the slow growth of celery and the increase of cellulose, resulting in a serious decline in taste, and the taste is not crisp, and at the same time, the astringency of celery increases, resulting in a decrease in the overall quality of celery, and the commodity value of celery is not sold well, which affects the income of farmers who planted celery that year.

The specific method is to dilute urea with water (pay attention to the dosage, the page will turn yellow if you apply too much fertilizer), and then spray it on the foliage of the vegetable, which is suitable for vegetables that are not edible and have large leaves.

In fact, there is no need to worry, celery absorbs the nutrients inside, and the dirt remaining on the celery will be washed away by rainwater, not to mention that it must be washed over and over again when eating.

Water more. Water can dilute urea, so it will be less harmful to celery.

There aren't many good ways to do it, but we can water celery within a manageable range to dilute the urea content.

1. A large amount of nitrogen fertilizer needs to be applied to celery throughout the growth period, but urea cannot be applied.

2. Because after applying urea, the celery fiber will increase and become thicker, the plant will age, the growth will be slow, and the edible will be pure and old with bitterness, and the quality will be inferior. Ammonium carbonate, ammonia and organic fertilizer should be used to fertilize celery, which is beneficial to the improvement of quality.

3. Celery is a common dish on the table, and it is widely planted. Practice has shown that there are some well-established good practices that are not suitable for celery cultivation, for example, the topdressing of urea when fertilizing celery. Celery belongs to leafy vegetables, and the role of nitrogen fertilizer in the growth of celery is very prominent, the production of 1000kg of celery requires 2kg of pure nitrogen, and the yield of 1000kg of celery per mu needs 8?

10kg。

1. A large amount of nitrogen fertilizer needs to be applied to the whole celery for a long time, but urea cannot be applied.

2. Because after applying urea, the celery fiber will increase and become thicker, the plant will age, the growth will be slow, and the food will have a bitter taste and poor quality. Ammonium carbonate, ammonia and organic fertilizers should be used to fertilize celery, which is conducive to improving quality.

3. Celery is a common dish on the table, and it is widely planted. Practice has shown that there are some recognized good methods that are not suitable for celery cultivation, such as changing the pure theory, and applying urea kernel when fertilizing celery. Celery belongs to leafy vegetables, and the role of nitrogen fertilizer in the growth of celery is very prominent, 2kg of pure nitrogen is needed to produce 1000kg of celery, and 810kg is required to produce 1000kg of celery per mu.

Celery is suitable for growing in cold, humid climates, and it is also a semi-hardy vegetable. The nutritional value of celery is still relatively high, so everyone still likes this vegetable very much. However, special attention must be paid to the process of planting, because celery also needs a better climate and environment.

As long as this can better ensure the quality of celery, and also allow farmers to have a good harvest. Celery should not only be paid attention to when planting, but also fertilization in the later stage is more important. Therefore, farmers should also work harder, after all, celery is still a very nutritious green leafy vegetable.

Farmers need to work hard, celery needs to pay attention to a good situation in the process of topdressing in the later stage, and also needs to have a certain demand for fertilizer and water. Everyone also thinks that celery is a very hardy vegetable, so farmers also need to give celery a very good growing environment. I hope that every farmer can be very careful in the process of planting, so that they can also have a good harvest.

After all, celery still needs good attention when planting in the early stage, and celery is relatively adaptable to the soil. Therefore, farmers should also be extra careful in the process of planting, and must have sufficient water**. If there is a long-term lack of water, it may cause the leaves to turn yellow and even the stems to age.

This also makes celery have a bad growing environment, and it will also lead to some bad situations. Therefore, topdressing is a very critical step in the later stage, and farmers also need to buy some more reliable fertilizers. In this way, celery can have a very good growth process and make it more nutritious.

Fertilization and watering are requiredIn the later stage, there are many situations that should be paid attention to in the process of top dressing, and everyone also thinks that celery is a vegetable that needs to be fertilized and watered regularly. This is the only way to ensure that the other is more nutritious and does not lead to a lack of water in celery. Because celery needs to be cultivated in large quantities in the early stages, and it also needs to be well fertilized and watered in the later stages.

Top dressing should be based on ammonium bicarbonate, do a small amount of many times, generally need to top dressing 2 3 times, celery top dressing can not blindly apply nitrogen fertilizer, but less potassium fertilizer or phosphate fertilizer will cause bad symptoms of celery

It is necessary to choose the right time for top dressing, do not fertilize before the rain, use the principle of fertilizing once in small quantities and many times, do not apply too much, and also pay attention to the growth of celery.

First of all, you should choose phosphate fertilizer and nitrogen fertilizer, but also should choose some farm fertilizer, and then choose the right time to fertilize, but also to ensure that the light is sufficient and the temperature is suitable, and do not top dressing in windy or rainy weather.

When fertilizing, you should first water it, and then sprinkle fertilizer, try to make some compound fertilizer or urea, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and the like, so that celery can grow better.

1. Apply sufficient base fertilizer.

The growth period of celery is long, and sufficient basal fertilizer should be applied before planting. The base fertilizer is mainly organic fertilizer, and before transplanting and planting seedlings, 4000-5000 kg of rotting farmhouse fertilizer can be applied per mu, and combined with land preparation and sprinkling into the soil. A small amount of chemical fertilizer, especially phosphorus and potassium fertilizer, should also be appropriately applied in the base fertilizer.

2. Timely top dressing.

When tomato seedlings are planted, a small amount of nitrogen fertilizer can be applied, and urea is generally 5-7 kg per mu. In the early stage of celery seedlings, because the seedlings grow slowly and the amount of fertilizer is small, there is generally no need to fertilize.

When celery begins to grow vigorously, nitrogen fertilizer can be applied again, generally 10-15 kg of urea per mu, and combined with irrigation. Celery grows more vigorously after this topdressing, and nitrogen fertilizer is applied again after 15-20 days of fertilization.

Now if you want to fertilize, first of all, before planting, you should choose the rotten chicken manure, and then apply some dry matter to supplement calcium fertilizer, actively apply some compound fertilizer during the growth of seedlings, and appropriately supplement some other fertilizers, and spray some other fertilizers in the process of growth, which is more helpful for celery follow-up methods such as wet base fertilizer, top dressing and glue sunlight.

Reasonable fertilization according to the growth of plants, you can use some farmhouse fertilizer, be sure to pay attention to the time of fertilization.

After planting, the seedling stage is generally not topdressed. After slow seedling, the plant grows very slowly. In order to promote the growth of new roots and new leaves, seedling fertilizer can be applied at one time, and urea 5 7 kg per mu can be applied.

During the vigorous growth period, the leaf area expands rapidly, the petiole elongates rapidly, the parenchyma in the petiole proliferates, and celery grows vigorously, which is the period when the nutrient efficiency is the largest. At this time, it is necessary to top dressing several times, mainly fast-acting nitrogen fertilizer. To make celery high-yielding, clever fertilization is the key to planting celery for the first time combined with irrigation, applying urea 6 to 8 kg per mu.

After 10 to 15 days, urea 5 to 7 kg per mu can be applied. In addition to nitrogen fertilizer, potassium fertilizer should be added, 5 kg of potassium sulfate per mu should be applied each time, watered thoroughly, so that the heart leaves are tender and juicy, and organic matter can be fully transported and accumulated.

If heart rot is found in celery during growth, calcium nitrate can be sprayed on the leaves. Foliar spray of boron fertilizer can avoid stem cracking to a certain extent, and 40 75 kg of borax or boric acid solution per mu is applied each time. Fertilization MythsSome farmers often think that celery mainly has leaves, so it is necessary to apply more urea or high-nitrogen fertilizers to make it grow healthily.

In fact, this is not entirely true, because if there is too much urea, the growth of celery will not only slow down, but also increase fiber, the plant will be prone to aging, and the quality will be reduced. There will be a bitter taste when eating, and the taste will have a certain effect. Major farmers have noticed that if the use of phosphorus, potassium and calcium fertilizers is neglected, it is easy to cause celery to be hollow.

How to increase celery yield? What are some tips for celery fertilization? Fertilization method When planting celery with basal fertilizer, it is best to apply 400 kg of well-rotted chicken manure as basal fertilizer, and then add 20 kg of balanced fertilizer, that is, three kinds of 15 balanced fertilizer.

This can supplement the content of nitrogen, phosphorus and potassium, and organic fertilizer can improve the quality of celery. The stems of the plant are tender and strong, and the cellulose is reduced. Do not apply organic fertilizer that is not completely decomposed to avoid root rot.

Then, on top of the above, 15 kg of calcium nitrate is added. Supplementing an appropriate amount of calcium fertilizer can avoid black heart disease and heart rot in the late growth stage of celery. In addition, applying about kilograms of borax per mu can also prevent celery from hollowing and breaking roots.

After the celery is planted to survive, it is lightly applied to the manure of the ripe manure, and then topdressing every 10-15 days. In the middle and late stages, a large amount of water and fertilization should be applied to increase the internal nutrients of the plant, promote the vigorous growth of stems and leaves, and enrich the petioles to prevent hollowing, so as to facilitate high quality and high yield. A small amount of chemical fertilizer should be added to the well-rotted manure water, and 3-4 kg of urea and 5 kg of potassium fertilizer should be applied once per mu.

When fertilizing, be careful not to pour from the heart leaves. In addition, in the middle and early stages of plant quality, top dressing is carried out 2-3 times to supplement soil nutrients. Calcium chloride solution and borax solution are sprayed respectively to prevent diseases such as black heart disease and petiole cracking.

Root topdressing is best carried out on cloudy or sunny days, when the dew is not dry in the morning or when the temperature is slightly lower in the evening, which is conducive to the absorption of fertilizer by the leaves. 20-30 days before the harvest period, 920 can be sprayed 1-2 times at a concentration of 20-50 ppm, which can make celery quality tender and increase yield.
