After celery transplantation, the seedlings return slowly, and the growth is slow

In the early stage of growth after celery planting and slow seedlings, the development is slow, the nutrient absorption is small, and fertilizer can be omitted. When the plant grows 5 or 6 leaves, it enters the peak growth period, and a top dressing is carried out, and 10 15 kg of urea is applied per mu. After an interval of 15 to 20 days, when the plant has grown 8 to 9 leaves, the second top dressing is carried out.

This fertilizer should be reapplied, and nitrogen, phosphorus, potassium fertilizer is required to be applied together, and "fertile leaves" compound fertilizer can be applied per mu. During the vigorous growth period, foliar fertilizers can also be applied, such as spraying urea solution, or "potassium dihydrogen phosphate in fertile leaves". Autumn drought is prone to boron deficiency, which can be sprayed with a solution of "fertile leaf boron" to prevent rough and cracked petioles.

Celery is one of a kindHardy, cold-loving vegetables that are not heat-tolerant。Seeds start germinating at 4 and 15 to 18 is the most suitable temperature. It does not germinate easily in high temperatures in summer.

As a result, celery germinates more slowly in the summer, which is the main reason why many growers grow slowly and irregularly due to high temperatures. Experienced people may have experienced that the early celery sprouts were already very tall and there were still celery sprouts in the ground, resulting in problems with the size of the celery seedlings.

1.Fertilizer damage: pesticide damage or fertilizer damage caused by excessive drug or fertilization.

2.Herbicides: Hazards caused by herbicide residues used in the planting of previous crops. 3.Lack of water: Before the heart leaves grow, it is necessary to keep the surface dry and wet, and when there is a shortage of water, it should be watered shallowly to promote slow seedlings.

Celery does not take root for a long time after transplanting should be not nutritious, you try to fertilize some, or use farmhouse fertilizer, so that it can replenish the nutrients it needs and can take root quickly.

July-August, is the hottest period of the year, celery outer leaf growth is suitable for 18-24 degrees, heart leaf hypertrophy is suitable for 15-20 degrees, July-August, is the hottest period of the year, the temperature greatly exceeds the suitable temperature, so the transplanting is not long.

7 to 10 days. Celery seedlings are generally ready to emerge in 7 to 10 days after sowing, provided that they are at the right temperature, in the range of 15 to 20 degrees Celsius, and that there is also plenty of moisture and enough oxygen.

After celery emerges, it is necessary to do a good job of light and temperature management, properly shade it on sunny days, keep the soil slightly moist, and apply 2-3 times of thin decomposed liquid fertilizer.

If the seeds are not germinated, the emergence time will be relatively prolonged, generally to wait for about 20-30 days, when planting celery, to choose high-yield, disease-resistant and insect-resistant seeds, and then sieve again, the inferior seeds are eliminated.

It's usually about 57 days.

Celery seedlings grow slowly, it may be that the planting soil is not suitable for the growth of seedlings, and the soil needs to be replaced and replanted, or it may be that the water and nutrients provided for celery seedlings are improper during maintenance, and it is necessary to provide water and fertilizer for the plants reasonably, or it may be that the seedlings are exposed to strong light during the growth process, and they need to shade the plants.

1. The soil is unsuitable

Celery seedlings grow slowly, which may be due to the fact that the planting soil is not suitable for the growth of the plant, resulting in damage to the roots, so when the celery seedlings are maintained in the later stage, the plant can be replanted by replacing the soil. Celery seedlings are suitable for growing in soil rich in trace elements, and rich and loose humus soil can be used for replanting celery.

2. Insufficient fertilization

Celery seedlings grow slowly, or it may be due to insufficient fertilization, resulting in the plant can only maintain normal growth and cannot improve the growth rate, so in the later maintenance, you can provide celery seedlings with nitrogen-based fertilizer to make the plant grow more vigorously. However, nitrogen fertilizer should not be used alone to avoid the phenomenon of plant growth.

3. Overwatering

Celery seedlings grow slowly, or it may be overwatered, resulting in water accumulation at the roots of the plant, at this time, it is necessary to loosen the soil for celery seedlings in time, drain the excess water in the soil, and then ventilate the plant, and use the wind to evaporate the remaining water in the soil, so that the plant can grow better.

4. The light is too strong

Celery seedlings have a certain demand for light in the process of growth, but too strong light irradiation of seedlings will cause sunburn and slow growth, so when maintaining celery seedlings in the later stage, they can be placed in an environment with sufficient astigmatism, waiting for the seedlings to grow and mature, and then provide them with sufficient light.

Summary. Hello, the following situations may cause celery not to grow and turn yellow.

Hello, the following situations may cause celery not to grow and turn yellow.

1.Fertilizer damage or excessive fertilization caused by drug and seepage damage or fertilizer damage. 2.

Herbicide residues used in the planting of plants before stubble are created and seep into the hazard of leakage. 3.Lack of water: Before the heart leaves grow, it is necessary to keep the surface dry and wet, and when there is a shortage of water, it should be watered shallowly to promote slow seedlings.

Summary. Celery, a plant of the Apiaceae family. There are two kinds of water cress and dry celery, which have similar functions, and the medicinal use is better than dry celery.

The aroma of celery is stronger, also known as"Parsley", also known as:"Medicinal parsley"。Celery is a high-fiber food, it produces a kind of lignin or intestinal lipid through intestinal digestion, this kind of substance is an antioxidant, often eat celery, especially eating celery leaves, it is very beneficial to prevent high blood pressure, arteriosclerosis, etc., and has an auxiliary effect.

Fertilizer damage: pesticide damage or fertilizer damage caused by excessive drug or fertilization. 2.Herbicides: Hazards caused by herbicide residues used in the planting of previous crops.

3.Before the lack of water heart leaves grows, it is necessary to keep the surface dry and wet, and when there is a lack of water, it is necessary to water shallowly to promote the slow seedlings.

Love, celery, key town belongs to the clear attack Apiaceae plant. There are two kinds of water cress and brother dry celery, which have similar functions, and the medicinal use is better than dry celery. The aroma of celery is stronger, also known as"Parsley", also known as:"Medicinal parsley"。

Celery is a high-fiber food, it produces a kind of lignin or intestinal lipid through intestinal digestion, this kind of substance is an antioxidant, often eat celery, especially eating celery leaves, it is very beneficial to prevent high blood pressure, arteriosclerosis, etc., and has an auxiliary effect.

Summary. 1. After celery planting, it takes a time to slow the seedlings, and after the seedlings are finished, strengthen water and fertilizer management to allow the seedlings to quickly resume growth. After celery seedlings are slowed down, squatting for too long will also affect root growth.

Celery also tends to grow slowly if it hurts its roots when it is planted, or in areas that are dry and fertilizer-deficient. Celery with yellowing leaves and defertilization should be watered and topdressed in time. When watering, when the soil is compacted, the soil should be loosened in time.

1. After celery planting, it takes a time to slow down the seedlings, and after the end of the slow seedlings, strengthen water and fertilizer management to allow the seedlings to quickly resume growth. After celery seedlings are slowed down, squatting for too long will also affect root growth. Celery planting hurts the root system, or in a drought and lack of fertilizer to take the plot, it is also prone to slow growth.

Celery with yellowing leaves and deferencing should be watered and topdressed in time. When watering, when the soil is compacted, the soil should be loosened in time.

2. After the beginning of winter, the temperature of Qiaojianyin drops sharply, the vitality of the root system is weak, the ability to absorb water and fertilizer is weak, and the growth rate of stems and leaves and roots is slow, or even stops growing. Celery has a certain ability to tolerate cold, and when frost occurs, it should be kept warm in time. Before the frost comes, those who do not cover the film should be covered in time.

The cold shed can be planted in the sensitive hall, which can be covered with two membranes to increase the temperature in the shed, promote the growth of celery stems and leaves, and not be damaged by frost.

3. When celery grows, on the one hand, it relies on the roots to absorb nutrients and grows the stems and leaves, and at the same time, the stems and leaves carry out photosynthesis to produce nutrients to promote the growth of the stems. When it is rainy continuously, the light is less boring, the photosynthesis is weak, and the growth rate of celery is slow. In this case, some foliar fertilizer should be sprayed to improve the stress resistance of celery.

4. Some farmers see that celery grows slowly, so they often spray some plant growth regulators, such as gibberellin, triasanol, brassin, etc. If there is a shortage of fertilizer and water next to the car, spraying the regulator can promote growth, but there will also be weak stalks, hollow, etc., which will affect the quality of celery. Therefore, it must be scientific when spraying plant growth regulators.

It is recommended to be sprayed with foliar fertilizer, such as urea, boron fertilizer, etc. Second, after spraying and reapplying, it is necessary to pay attention to the temperate leakage in the celery shed, and the effect of brassinin and triasanol is poor at low temperature.

When the growth and burning rate of celery is slow after planting, the above four situations generally occur, and farmers should first find out the cause, and then remedy the root failure as soon as possible, so as to promote the rapid growth of celery, improve the yield and quality.

There are various reasons why celery leaves turn yellow. Long-term rainfall or excessive watering will cause yellow leaves due to excessive soil moisture, and long-term drought, insufficient watering or not watering in time, will cause yellow leaves due to drought and lack of water. If the planting land is too poor, it will cause yellow leaves due to lack of fertilizer, but too much fertilizer, or the way of fertilization is incorrect, and improper fertilizer types will cause fertilizer damage, such as ammonia poisoning, and eventually yellow leaves.

When the planting area is too shady, there is no light or there is not enough light, yellow leaves will also appear.
