What foliar fertilizer does celery get? When is the best time to apply fertilizer?

In the process of growth, celery has the characteristics of low fertilizer absorption capacity and strong fertility tolerance, and has high requirements for soil fertility. During the growth process, a large amount of nitrogen fertilizer needs to be applied, but urea cannot be applied.

Spraying foliar fertilizer on vegetables can not only save fertilizer and have a quick effect, but also increase production and income. However, foliar fertilizer spraying should master the spraying technique and spraying time, and the selection should vary from crop to crop, so as to maximize the good effect.

The foliar fertilizer we commonly use is mainly applied in the middle and late stages of field vegetable growth, which has the characteristics of simple operation, less fertilizer consumption, high utilization rate, fast effect and obvious effect. Spraying foliar fertilizer can make up for the nitrogen, phosphorus and potassium needed for vegetable growth in time.

and other trace elements.

So as to achieve the fertilizer efficiency and micro fertilizer that increases the yield of micro-fertilizer.

<> morphological relationship between macronutrients is closely related, and micronutrients must be stable and soluble in foliar fertilizer. Metal complexes.

or chelate can increase the stability and mobility of micronutrients, so on metal chelate than bulbs, root vegetables and shallots.

For garlic, radish, carrot, potato, taro and other vegetables, foliar fertilizer is generally dominated by phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate.

solution, superphosphate.

and plant ash immersion liquid, etc.

Boron that can be sprayed on root vegetables There are many kinds of foliar fertilizer on the market at present, its composition is also different, the nature and use are different, and the range of applicable vegetables is also different, the vegetables based on the total stems and leaves, such as Chinese cabbage, cabbage, spinach, celery, bamboo shoots, leeks and other vegetables like nitrogen, there are many kinds of foliar fertilizer vegetables, no matter which one, there are certain characteristics, vegetables in the seedling stage, you can use rooting and seedling strengthening agent, rooting and seedling strengthening agent is containing a variety of trace elements, spraying can be reduced.

In the case of less dead seedlings, the leaves are yellow during the growth period, and if the bottom fertilizer is insufficient, fertilizer should be applied at the celery seedling stage. Growers should apply fully water-soluble fertilizer in time at the seedling stage, and use it together with the new high-lipid film to improve fertilizer utilization rate and effectively prevent bacterial infection. Take Wenwen's hometown to sow small parsley as an example, small parsley does not need to be transplanted after sowing for a period of time, and when it grows up, you can directly pull it out to eat or pick some leaves to eat, so if you want parsley to grow better, sowing bottom fertilizer is very important, we are all trying our best.

Celery can be hit with foliar silicon fertilizer, selenium-rich foliar fertilizer, spray selenium-rich foliar fertilizer use time description:

Spraying time: depending on the degree of pollution of cultivated land, 1-2 times can be selected 1-20 days after the fixed value of celery (celery growth period); Choose a sunny or cloudy day to spray around 4 p.m.

Dosage description: about 1 bottle per mu each time; Artificial spraying needs to be mixed with water 100-200 times; UAV spraying with water 10-20 times; Foliar sprays are applied. Based on the principle of foliar dripping.

Field management: Same as normal field management.

Foliar fertilizer with more nitrogen should be used, and the general fertilization time is in the morning, when the temperature is just right, and at the same time, it can also ensure the absorption of celery nutrients.

Urea, ammonium sulfate, choose these two kinds of foliar fertilizer is more suitable, the best time for fertilization is in March and April in the spring, be sure to add fertilizer.

Foliar sprays should be used, and photosynthesis can also be used, so that it will be fully absorbed, and the best time to apply fertilizer should be from March to April every year, so that it is best and reasonable.

Celery is increased by potassium fertilizer, and potassium fertilizer will promote the expansion of celery petioles and increase the growth rate. Nitrogen fertilizer will increase the length and number of leaves in the petioles, and phosphorus fertilizer will increase the cellulose contained in the petioles of celery. Cultivation of celery, yo it needs to be placed in a semi-shaded place, receive scattered light, strong light in summer needs proper shade, its growth period, need to apply nitrogen, phosphorus and potassium compound fertilizer.

Celery grows quickly with potassium fertilizer, and celery has the characteristics of low fertilizer-loving ability and strong fertilizer tolerance, which has high requirements for soil fertility. Applying potassium fertilizer to celery can promote the expansion of celery petioles, improve yield and quality, and also quickly accelerate the growth rate of celery.

If you want to have a high yield of celery, you need to apply nitrogen fertilizer, which mainly affects the development of aboveground parts. Applying nitrogen fertilizer to celery will increase the length and number of leaves of the petioles. If you want celery to taste good, you need to apply phosphorus fertilizer, which will increase the cellulose content in celery leaves.

To grow celery, you need to choose loose and fertile soil with good drainage and air permeability. It is necessary to ensure that the growth temperature of celery is 15 25, if the temperature is lower than 15, germination will be delayed, but if it is higher than 30, the seeds will basically not germinate.

Celery does not require much light, so it needs to be placed in semi-shade and exposed to scattered light for four hours a day. In summer, the light is strong and proper shade is required to avoid wilting of celery leaves. During its growth period, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote plant growth.

A large amount of nitrogen fertilizer needs to be applied to celery throughout the growing season, but urea should not be applied. Because after applying urea, the celery fiber will increase and become thicker, the plant will age, grow slowly, and eat with bitter taste, and the quality is inferior. Ammonium carbonate, ammonia and organic fertilizers should be used to fertilize celery, which is conducive to improving quality.

What fertilizer is good to apply for celery.

1. Apply nitrogen fertilizer. 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.

2. Apply organic fertilizer. Top application of organic fertilizer can improve the quality of celery. Applying organic fertilizer to poultry such as chickens and ducks, celery plants are tender and thick, the fiber is reduced, and the quality and yield are greatly improved.

However, the organic fertilizer of the farmhouse that is not well rotted should not be applied as top dressing, so as not to cause burning and rotting roots.

3. Apply micro-fertilizer. Supplemental application of micro-fertilizer can prevent physiological diseases of celery. Calcium deficiency will cause celery "heartburn", and boron deficiency will cause celery hollowing, petiole cracking and other physiological diseases.

Foliar sprays of calcium chloride or calcium nitrate in water can prevent celery "heartburn". In order to prevent celery hollow and petiole cracking, kilograms of borax can be applied per mu, or foliar spraying with borax solution.

Do you know what fertilizer to use for celery? Different fertilizers have different effects, and celery fertilization should be scientifically fertilized according to the fertilizer characteristics of celery. Nitrogen mainly affects the development of celery shoots, i.e. the length of the petiole and the number of leaves.

Phosphate fertilizer mainly affects the quality, and when there is too much, the petiole is slender and cellulose is more. Sufficient potassium fertilizer is conducive to the expansion of petioles, improving yield and quality.

What fertilizer is good for celery top dressing? More nitrogen fertilizer should be applied. Celery needs a lot of nitrogen fertilizer during the whole growth period, and the top dressing of celery should be dominated by ammonium bicarbonate. To do a small amount many times, it is generally necessary to top dressing two to three times.

Hello landlord, if celery topdressing organic fertilizer is the best and safest, if it is grown at home to eat,

Celery as a stalk leaf vegetable, has the effect of 2113 lowering blood pressure, rich in nutrition, 5261 occupies a certain position in vegetables, in the process of planting 4102 can be used Demer Tianye concentrated phosphorus and potassium essence, the effect is a single phosphorus 1653 acid potassium dihydrogen potassium eight times, the yield is significantly increased, you can also use crop special foliar fertilizer, the whole crop growth period can use celery top dressing with nitrogen fertilizer, but should not be topdressing urea. Celery needs a lot of nitrogen fertilizer during the whole growth period, and the top dressing should be mainly ammonium bicarbonate, so that a small amount of it is done many times, and it is generally necessary to top dressing 2-3 times. However, celery should not be top-applied with urea, because the growth of celery is slow after top-dressing urea.

1. Raise the fertilization time of celery.

Fertilization of celery can be carried out at the seedling stage and the growth stage. If it is spring celery, it can be fertilized in the month; In the case of autumn celery, fertilization is required in July and August; In the case of retained celery, fertilization is required during the flowering period.

2. The fertilization method of celery will be discussed.

When applying celery, proper fertilization methods should also be taken. When the soil color becomes darker, it means that the soil is more fertile, at this time the fertilizer can be diluted, irrigated in the soil, so that the celery can absorb enough nutrients, when the soil color becomes lighter, it means that the soil lacks fertilizer, at this time, fertilizer can be added directly to the soil.

3. Fertilizer selection for celery.

When applying celery, it is also necessary to choose the right fertilizer. In the seedling stage of celery, the growth rate of the plant should be increased. Nitrogen fertilizer can be applied at this point.

4. Transportation and maintenance of celery after fertilization.

In the later stage of celery maintenance, mineral-rich purified water and natural water can be poured into the soil to keep the soil moist, and it can also provide celery with a full day of sunlight, keep the leaves green, and the leaves can be picked regularly to improve ventilation between the plants and make the plants grow better.

celery during the growth process. At different stages of growth and development, different fertilizer types and fertilization techniques are needed to make celery grow faster.

1. Seedling fertilizer.

Celery cultivated in protected areas is generally nursed before being planted. The preparation of nutrients can refer to the preparation method of tomatoes, or it can be mixed with 1 2 vegetable garden* and 1 2 rotten or semi-rotted compost according to the volume ratio to make nutrients*, and superphosphate is mixed with 2%-3% by weight. At 30 days after the emergence of seedlings, a low-concentration nitrogen fertilizer should be applied once as appropriate, and 0,2 kg of ammonium sulfate or decomposed dilute human feces per furrow should be applied.

Second, the base fertilizer. Due to the shallow root system of celery and the high cultivation density, it is necessary to apply foot fertilizer when preparing the land before planting. 4000-5000 kg of organic fertilizer and 30-35 kg of superphosphate are applied per mu.

25-20 kg of potassium sulfate, 1-2 kg of borax per mu can be applied to boron-deficient soil.

3. Top dressing. In order to promote the growth of new roots and leaves, you can apply a seedling fertilizer, 10 kg of ammonium sulfate per mu with water, or 500-600 kg of rotten human feces and urine to start dust. From most of the new leaves to the vigorous growth period of the plant before harvest, the leaf area expands rapidly, the petiole elongates rapidly, the parenchyma in the petiole proliferates, the celery absorbs a large amount of fertilizer, the fertilizer absorption rate is fast, and it is necessary to top dressing in time.

For the first time, 7-9 kg of urea or 15-20 kg of ammonium sulfate and 10-15 kg of potassium sulfur were applied per mu. Half a month after the first topdressing, celery enters the vigorous growth period, the fine white roots are covered with the ground, the leaf color is bright green and shiny, and some bulges appear on the leaf surface. After about 15 days, the third top dressing is carried out, and the fertilizer amount is the same as the first time, or the fertilizer amount is increased or decreased depending on the growth of celery.

The amount of nitrogen fertilizer and potassium fertilizer should not be too much each time, and the high concentration of nitrogen and potassium in the soil will affect the absorption of boron and calcium, causing the young tissues of celery heart leaves to turn brown and appear dry edges, and die in severe cases, and it is more serious when the irrigation is insufficient, the soil is dry and the ground temperature is low. Therefore, it is necessary to control the amount of nitrogen fertilizer and potassium fertilizer, increase the application of boron fertilizer and calcium fertilizer, keep the soil moist, and avoid the temperature being too low. When the plant is deficient in boron, it is also prone to stem fissures, which mostly appear on the inner side of the outer petioles.

Boron deficiency occurs during the development of the heart lobe, and the inner tissues turn brown and crack.

Fourth, foliar fertilizer.

During the growing season of celery, foliar sprays of urea or potassium nitrate solution can be used. Promotes the growth of its stems and leaves. In case of dry weather, foliar sprays of Soluboron solution can be applied to prevent petioles from roughening and cracking.

Celery is a vegetable that requires high soil fertility. Although celery does not have a high amount of fertilizer, it has a high fertility tolerance. If the amount of fertilizer is too small, it will not only affect the growth, but also the quality will not be good.

Nitrogen fertilizer is the key to ensure good leaf growth during the whole growth process of celery, which has a great impact on the yield, but it is necessary to pay attention to the dosage.

Celery requires more fertilizer at the seedling stage and later stage, and the plantar fertilizer is applied, mainly organic fertilizer, and potassium fulvic acid from mineral sources is applied or sprinkled in the field with 300 500 kg of water to promote rooting. In addition to nitrogen fertilizer, it is necessary to cooperate with phosphorus and potassium micro-fertilizer, and spray foliar fertilizer Kunlun wind to make the heart leaves tender and juicy, which helps to improve quality and yield.
