How to Plant Celery
The article provides a small green plant maintenance experience on how to plant celery and understand celery cultivation techniques, the specific content is as follows:
To plant celery, first select high-quality seeds, then perform low-temperature germination to break the seed dormancy, and most seeds can be sown after they turn white. Prepare a suitable seedbed, apply base fertilizer and finely till the soil, while also ensuring measures for insulation, rain prevention, and shading. When the seedlings have 5-6 true leaves, they can be transplanted. During transplanting, grade the seedlings, water thoroughly, and plant them in wet soil. Let's take a detailed look next.
1. Seed Treatment
Celery is usually sown and seedlings raised from mid-June to late July. High temperatures make it difficult for seeds to germinate, so seeds should be treated with low-temperature germination. The seeds can be soaked in cool well water for a whole day, or soaked in 50ppm of gibberellin (920) as well. After soaking for 12 hours, rinse the seeds clean, dry them for 20 minutes to ensure they do not stick together, and then place them in an environment of 18-20°C for germination. Once most seeds have turned white, they can be sown.
2. Preparing the Seedbed
In the summer heat, celery prefers shady and cool conditions. It is recommended to prepare a seedbed in a shaded and well-irrigated area with good drainage. Use decomposed manure as the base fertilizer, mix it with the soil, and till the land. Mix sand with the seeds before sowing to ensure even distribution. After sowing, cover with 0.5 cm of fine soil. Water the seedbed thoroughly after sowing, set up a shed, and take measures for shading, rain prevention, and insulation. During the seedling stage, maintain the soil moisture.
3. Seedling Management
Thin the seedlings when they have 2-3 true leaves, based on their growth, thin 2-3 times. When the seedlings have 3-4 leaves and reach a height of 6-7 cm, the plastic film can be removed.
4. Proper Transplanting
By late August, seedlings with 5 true leaves can be transplanted. Grade the seedlings and choose well-grown medium-sized seedlings for transplanting. Prepare the field ridges, water thoroughly, and plant in wet soil, which helps seedlings adapt quickly and promotes root growth.
5. Water and Fertilizer Management
Water thoroughly during transplanting, and after 15-20 days, keep the soil slightly dry. Remove weeds promptly. One month after transplanting, water every 5-7 days and apply fertilizer every 10-15 days, using 20 kg of urea and 15 kg of diammonium phosphate per mu of land. Water frequently during high temperatures and stop watering 7-10 days before harvest.
6. Pest and Disease Control
For leaf spot and leaf blight, use 5% carbendazim powder at 1 kg per mu of land, or 45% carbendazim smoke fumigant at 200-250g. For pests like aphids and leafminer flies, use pyrethroid insecticides, with an interval of 7-10 days between applications, and apply 2-3 times consecutively.
