What to do with freshly unearthed celery seedlings?

It is necessary to adjust the temperature and moisture. At the seedling stage, we should pay attention to the germination of seeds, and pay attention to the dryness, humidity and light intensity of the soil. However, the whole seedling period should be covered with a shade net, and when the celery seedlings grow a pair of cotyledons, the shade net can be properly removed.

Remove the plastic film immediately after the celery seedlings emerge to prevent overgrowth. The warm climate during the day is not suitable for overheating, which is an important condition for the growth of seedlings. If the temperature is high, it is necessary to ventilate it in time, and there is no shortage of water throughout the seedling period, the seedbed is high temperature and dry, and the seedlings grow slowly; High temperature and high humidity make the seedlings crisp and tender, and they are susceptible to seedling diseases.

In short, in seedling management, no matter what protective facilities are used to raise seedlings, it is necessary to create a cold and humid environment.

After the celery seedlings are unearthed, nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes, and regular watering should be carried out to keep the soil moist. Give plants more ventilation.

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 does not germinate in 20-30 days.

After celery sowing, about 10-15 days can emerge seedlings, the whole Wu defeat and growth period in about 120 days, the growth rate is relatively fast, if the celery seeds are not germinated, the emergence time will be relatively prolonged, generally have to wait for 20-30 days. The low temperature at which celery seeds germinate is 4 degrees Celsius, and the suitable temperature is 15 to 20 degrees Celsius.

If the cavity is low at 15 degrees Celsius, the germination time of the seeds will be prolonged, the germination rate above 25 degrees Celsius will be significantly reduced, and the germination rate above 30 degrees Celsius will hardly be at all. When below 30 degrees Celsius, the greater the temperature difference, the higher the germination rate. The germination rate is higher when treated with a temperature change of about 25 degrees Celsius for 6 to 8 hours and 15 degrees Celsius for 16 to 18 hours.

Under suitable temperature conditions, germination can occur in 7 to 10 days. At the same time, the seeds must also have sufficient water for germination. It needs to be damp, dry and not resistant to drying. Generally, the water content is 70 to 80. Adequate oxygen is also required.

Celery cultivation work

The selection of celery varieties is very important, we should try to select seeds with high yield, disease resistance and insect resistance, screen for impurities before sowing, so as to improve the purity of the seeds, and dry them for 1 day after screening to reduce bacterial growth. Celery has strict requirements for soil, and it is necessary to choose loam or clay loam soil that is fertile, loose, has good aeration, and has strong water and fertility retention.

However, sandy soil and sandy loam soil are prone to water and fertilizer shortage, which makes celery petioles hollow. Celery root system shallow, high requirements for soil moisture, should be watered frequently, keep the soil moist, fertilization to basal fertilizer, accounting for about 80% of the total amount of fertilizer, in the later growth process of the plant, top application of 1-2 times of organic fertilizer.

Celery seeds are small, seedlings emerge slowly, and the growth rate after emergence is also slow, so there is no competition between celery seedlings and weeds. If the weeds are not pulled multiple times, the celery seedlings will eventually be "eaten" by the weeds. Therefore, the key to the success of seedling breeding is the ability to control weeds.

In order to control weeds, a lot of manpower is invested in pulling weeds. According to statistics, 70% of celery seedling management labor is used for weeding.

The herbicides commonly used in celery are: 40% flularin emulsion, 40% dilomine EC, 50% promethoxin wettable powder, 25% herbicide ether EC, 33% herbicide, etc.

Usage: Flulenin and dilonamine can be used before and after sowing, before transplanting and after transplanting, with a dosage of 100 150 grams per 667 m2 of 40% fluorole emulsifiable concentrate or 200 grams of 48% dilamine emulsifiable concentrate, or 500 grams of 25% herbicidal ether.

There are several issues to be aware of when using herbicides:

1) In order to avoid the long-term use of a single agent to make weeds resistant, a variety of agents can be used alternately to improve the weeding effect.

2) Soil treatment should be carried out before sowing or before emergence after sowing, that is, the best effect of pesticide application when weeds first bud. And Zixian stem and leaf spraying should be applied after the weeds are seedlings to improve the efficacy.

3) The furrow surface should be flat, the soil is finely broken and moist, so as to promote the germination of weeds together and facilitate the application of pesticides at one time.

Hello dear, glad to answer for you. The celery seedlings have just been unearthed and can beat the grass. Promecin is a systemic conductive selective herbicide.

The pure product is white crystalline and easily soluble in organic solvents. The dough is stable at room temperature and hydrolyzed under strong acids and alkalis. Non-combustible, non-explosive, non-corrosive.

Low-toxicity herbicide, safe for humans, animals and fish (acute oral toxicity LD50 2100 mg kg in pure rats), processed in 50% wettable powder. The main effect is to inhibit photosynthesis, hinder the synthesis of sugar and the accumulation of starch, plant roots, stems, and leaves absorb the agent, and make weeds die under the above effects.

The above is my finger on this question, if you think I'm very satisfied, please pay attention to me and don't get lost in the future, and then please do a little manual in the lower right corner, give me a like! Welcome to consult again <>

In the green vegetable market, you can see enough celery all year round, urban and rural residents can eat fresh celery all year round, this is because the growth of celery has strong adaptability to environmental temperature, humidity and other conditions, that is, it is hot and hot, counting nine cold days, celery is a green leafy vegetable that people love, celery is a shallow root plant, weak absorption capacity, strict requirements for soil nutrients and water, suitable for growing in soil rich in organic matter, water and fertilizer retention, requiring more nitrogen.

The treatment of seeds is the key when planting, and next, the farmer's sister-in-law will teach you the skills of handling seeds when planting celery, so as to help you grow tall and strong celery. The best temperature for celery seed germination is 15-20 degrees, although the temperature is too low, although celery seeds can also germinate, but the germination rate will be reduced.

Celery is a shallow-rooted vegetable, drought tolerant and waterlogging, like cold and cool climate, so we also call celery locally dry celery, the celery planted by my family is a kind of self-retained, the celery planted by the plant is selected to be large, robust trees, and so on after the seeds are mature, the celery seeds germinate when the temperature is harsh, the temperature is too high and too low will affect the celery germination, the best temperature for celery seed germination is 15-20 degrees, the temperature is too low although celery seeds can also germinate, but the germination rate will be reduced.

In the summer, it is planted around June, and in the fall, it is planted in August, so the temperature at this time is no longer suitable for celery germination, so it is now past the best time to plant celery. Celery can be planted all year round, but the varieties planted in each season are different, choose the varieties corresponding to the season, celery will not only grow well but also have a relatively high yield. Now entering the autumn and winter season, the celery varieties suitable for planting should be cold-resistant, and the market demand should choose celery seeds, generally choose better heat-resistant varieties in summer and autumn, and choose cold-resistant varieties in winter and spring.

It can be soaked in 48 degrees water for a period of time and then soaked in cool water for 24 hours.

Soak in water for 12 to 24 hours before sowing, then scrub the seeds, and then leave the cleaned seeds in a ventilated place to dry for a while, until the surface of the seeds becomes dry. Wrap the seeds in a damp towel and place them in a warm environment, taking care to keep the towel moist and wait until the seeds are budding before sowing.

Seed disinfection treatment, seed disinfection often adopts warm water soaking method, technology put the seeds into 48-49 warm water, soak the seeds for 30 minutes, and constantly stir, so that the seeds are heated evenly, and then take out the seeds and put them in cold water to cool.

Before planting, the seedlings should be promoted at low temperatures, which can ensure a certain yield in the future.

Celery round peiqing seeds are fruits, and the peel has poor water permeability, and it is difficult to absorb water and swell. In addition, celery seed germination has strict temperature requirements, and the suitable germination temperature is 15 20. In summer, when the temperature is high and the outside temperature exceeds 30, the germination rate decreases, and the germination time is also prolonged.

Celery seeds can germinate in about a week in a suitable environment, but in summer and autumn, it is necessary to create suitable conditions for seed germination. Therefore, celery sowing in summer and autumn generally needs to be soaked and germinated.

There are some differences between celery seed germination in summer and autumn and winter and spring. When the temperature is low, the seeds are germinated, soaked in warm water for 24 hours, washed again, and then germinated at room temperature, which is more convenient. There are also many methods of celery germination in summer and autumn, and we commonly use low-temperature germination and pharmaceutical germination.

1. Low temperature germinationWhen low temperature germination, the sowing time should be arranged, and the germination should be carried out one week before sowing. First of all, put the celery seeds in clean water and soak them for 24 hours, if you want to go faster, you can also soak the seeds in warm water at sixty or seventy degrees, about twelve small middle holes. But the temperature of the water should not be too high so as not to burn the seeds.

After soaking, wash the seeds with water, then remove them to dry and wrap them in damp gauze. Then put it in the environment of 15 20 for germination, generally 5 7 days of seedling emergence rate of 80%, you can sow seeds.

2. The agent germination gibberellin can promote seed germination, break dormancy, and can replace low temperature to treat celery seeds, thereby improving the seedling emergence rate of seeds and shortening the germination time. It can be soaked in 100 200 milliliters of gibberellin for 24 hours, and then sown after fishing, which can promote the rapid germination of celery seeds. Other growth regulators can also promote celery seed germination, but care should be taken for the duration and concentration of soaking when using them.

Here's how to grow celery and emerge quickly:

1. The celery germination process is also very simple, first soak the celery seeds in cold water for 24 hours, the water for soaking the seeds must be more, and the water should be changed once or twice in the middle to prevent the water from deteriorating, and then the seeds will be taken out and placed in a cool and ventilated place to dry until the surface of the seeds is white, during which the seeds are turned several times, and then the celery seeds are placed in a clean container, covered with a layer of wet gauze to moisturize, and placed in a cool, ventilated and cool place to promote germination, during which the seeds are rinsed with cold water once a day, and then continue to germinate.

2. Generally, celery seeds will be exposed in about 7 to 10 days, and about half of the seeds can be sown and seedlings can be sown before germination. Then sprinkle the seeds, because the celery seeds are particularly small, in order to spread the seeds evenly, you can mix the seeds with the sieve and sprinkle the seeds, so that the sprinklers are staring evenly, after the seeds are sprinkled, and then the rotten field is covered with 1 cm over the sun, and the ants sleep and then wait for the seedlings to emerge.

3. Before the emergence of seedlings, the seedbed can be covered with a shade net, the purpose of which is to prevent high temperature caused by strong sunlight, and second, it can moisturize to facilitate the emergence of seedlings. Generally, the seeds will emerge one after another in about a week, and they can be transplanted and planted when the seedlings grow to a height of more than 10 cm. After that, the management is relatively simple, just wait for the harvest to grow big enough.

4. In fact, the management of the whole growth cycle of celery is relatively simple, but some skills are needed in the seedling process, as long as it is mastered from the distance, celery planting is still very simple. I hope that the tips introduced can help celery growers emerge quickly.
