The daily management of celery is relatively simple, and the cultivation of celery in the greenhouse usually requires early seedlings. It is difficult to germinate celery, and the seedling can directly solve the problem of uneven growth of the seedlings. It can also shorten the planting time and mention the morning market. Today, Xiaobian will introduce the seedling technology of celery.
1, the sowing period of celery
Celery can be planted in four seasons of spring, summer, autumn and winter. The seedling age is basically about 70 days. It is generally expected that the sowing date will be pushed forward from the date of planting for about 70 days.
Planting celery in spring: seeding and seedling cultivation from January to March, planting in April-May, harvesting from June to July.
Planting celery in summer: seeding in April-May, planting in June-July, harvesting in August-September
Planting celery in autumn and winter: planting seedlings from June to July, planting in August-October, harvesting in October-October
Planting celery in winter and spring: seeding in August-October, planting in September-November, harvesting in November-April
As can be seen from the above time node, a reasonable grasp of the mouth, basically can harvest celery every month, the cultivation method of celery is relatively simple.
2, snoring
The roots of celery are relatively shallow, and the absorption capacity is relatively poor. Therefore, it is best to choose a fertile plot with a relatively high terrain. Before the nursery, you should deepen the land, apply enough organic fertilizer, refine the land, and then start snoring. The nursery nursery is generally recommended to have a width of 25 meters + 1.1 meters, and the surrounding height is about 20 centimeters. Under normal circumstances, the celery of the next mu of land needs 60 square meters of nursery.
3. Preparation of soil for nursery
The quality of the nursery soil determines the success or failure of the nursery. The seedling bed of 1 square meter needs about 100 kilograms of nursery soil. When preparing the nursery soil, it is necessary to ensure that the 100 kilograms of nursery soil contains 40 kilograms of decomposed organic fertilizer, and it is best to join Some carbendazim or nail to play a bactericidal effect. Prepare the seedling soil for 15 days and then use it.

4, the treatment of seeds
In the past when the seedling conditions were not mature, the hanging germination method was generally used in summer. The seeds were soaked in warm water of about 48 degrees for half an hour, then wrapped in a damp cloth and placed above the water surface of the well. Rinse with cold water and bud all in one week. Many growers now use refrigerators instead of hanging seedlings.
In winter, it is generally used 2 ml of gibberellin to water 2 kg, soaking seeds for 12 hours, and germination with a damp cloth under conditions of 15-20 degrees, so that the germination speed is fast and the budding rate is relatively high.
5, seeding method
The sowing time of celery is best in the afternoon to prevent the emergence of sun buds at noon. The celery should be irrigated once a day before sowing, and then sprinkle with a layer of fine soil after the water has been infiltrated, then spread the seeds with some moist fine sand and spread it evenly on the fine soil. After the sprinkling, cover it for about 5 mm. The fine dry soil can be used. In general, the seeding rate of the next square meter is about 25 grams. Note that the top layer of the soil should not be too much.
6, protective measures for celery seedlings
When the temperature is high, you should choose to use a sunshade with a shading rate of 50% to shield it from light. This can avoid the effects of high temperature. If you do not have the shading conditions, you can use the straw directly on the seedbed.
If the temperature is excessive, it is necessary to make a small arch on the seedbed, cover the plastic film, cover the grass felt or quilt at night, and play a basic heat preservation function. If you raise seedlings in the greenhouse, you don't have to worry too much about these problems. .
Keep the seedbed moist during the nursery period. If the surface is dry, spray the sprayer to keep the surface moist, but not too much water to avoid the death of rotten roots.
The effect of phosphorus on the yield and quality of celery is very large. According to the growth, potassium dihydrogen phosphate can be sprayed after 2 leaves and 1 heart. At the same time, it can be used twice, and can be used twice in the whole seedling stage.
In the process of intercropping, it should be noted that the celery plant spacing is about 4 cm, which is suitable for ensuring good ventilating and translucency of celery. When the celery height is as long as 20 cm, when five true leaves appear, it can be fixed. Already working.

The above is the seedling technology of celery. Celery can be planted basically all year round, and the yield is considerable, the income is also good, many people like to eat, the market demand is relatively large, friends who want to grow celery must master The above seedling technology.
