How to manage celery for high yield (planting density and yield of open-field celery)

What should we do to increase celery production?

Many farmers like to grow some celery in their own fields, but the celery grown by some farmers tastes particularly poor and has low yield, which is not as fresh and high-yielding as that grown professionally.

So how do you grow celery that has good growth, high yield, and is fresh and tender? Here are some good ways to grow celery.

First point, master the planting time

Celery prefers a cool climate, and the most suitable growth temperature for it is 15℃-25℃. It will be greatly affected by temperatures above 30℃ or below 5℃.

Therefore, when planting celery, you must cultivate it according to the ambient temperature. Generally, the sowing time in the south is in spring and autumn, and in the north it is around July .

Second point: understand the growth requirements of celery

Celery is a fertilizer-loving crop. It has a shallow root system and weak absorption capacity. When planting celery, you must choose a field that is cool, ventilated, well-lit, fertile, loose, has strong water and fertilizer retention, and has convenient irrigation and drainage.

Before sowing or transplanting, the field must be deeply plowed and dried before cultivation. The plowed and dried land can kill the pathogens and insect eggs contained in the soil, which will be beneficial for the rooting and sprouting of crops in the future.

Third point: Requirements for celery seedlings

Generally, it is best to choose water-lime soil for seedling cultivation on land. That is, choose a piece of good land, turn it over and dry it, cover it with a layer of dry straw, burn it once, add an appropriate amount of decomposed farmyard manure, turn it over and crush it, and level it, and then sow and raise seedlings the next day.

Fourth point: Rapid germination and seedling raising

Dry the purchased celery seeds in the sun for half a day, put them in a cloth bag, soak them in well water for 2 days, then take out the seeds and place them in a hole in the ground in a cool place. They will germinate in 3-4 days.

Or you can put them in the refrigerator for germination. If 80% of them have sprouted, they can be sown.

When sowing, first water the nursery ground once until the soil is moistened, then spread the seeds evenly into the soil, and then cover with 1 cm of fine soil.

During the seedling period, water lightly when the soil is dry. The nutrients required by the seedling stage are very few. Apply some nitrogen fertilizer appropriately one month after the emergence of the seedlings, but it must be a small amount to avoid fertilizer damage. The seedlings can be transplanted at about 50 days old.

Fifth point: prepare the land and apply fertilizer before planting

Before transplanting celery into the field, the land must be prepared in advance, and the pathogens and insect eggs in the soil must be killed by early plowing and drying, using sunlight.

If you are planting water celery, you should plant it in water or paddy fields, and prepare the land one week before planting. Add more than 3,000 kilograms of decomposed farmyard compost, 50 kilograms of nitrogen, phosphorus and potassium compound fertilizer, and 50 kilograms of quicklime per mu, and spread them evenly into the soil.

Turn the soil and fertilizer evenly and crush them into flat pieces to make a flat plot of land. After 3 days, you can transplant and plant.

Celery planting density is 20 cm row spacing, 10 cm plant spacing , water once after planting, until the soil penetrates. Celery seedlings must be watered once a day before they grow steadily, and then the amount of watering can be reduced after the seedlings survive.

Sixth point: Field water and fertilizer management

After the celery seedlings survive, they should be watered frequently to keep the soil moist, with a soil moisture of 65%-80%. In the early high temperature and drought season, a small arch shed can be built appropriately. Cover it with a shade net to provide shade, and water it with well water to cool it down. In rainy weather, drainage should be done well.

For topdressing, after applying enough base fertilizer, topdress again when entering the vigorous growth period. It is best to water more rotted manure water, or use nitrogen, phosphorus and potassium compound fertilizer mixed with water for watering. Usually, 50 kilograms of compound fertilizer per mu is mixed with 1,500 kilograms of rotted manure water for watering.

Celery is relatively less susceptible to diseases and pests. It is best to start with management, ensuring ventilation and light transmission, preventing high temperature and high humidity, drought and waterlogging, etc. Generally, diseases and pests will not occur. If you are worried, you can use carbendazim or thiophanate-methyl to prevent it.

Conclusion

In short, if you want to grow celery that grows well, is crisp and tender, you must plow and dry the fields in advance, and apply more decomposed organic fertilizer as base fertilizer. Keep the soil moist, and cool down and water more in hot and dry days. You will definitely be able to grow high-yield and high-quality celery.
