How to carry out celery nursery

Celery requires cool and moist environmental conditions, and has a certain degree of cold resistance, the suitable temperature for growth 15-20 °C. The seedling stage is more tolerant to high temperatures, and the seeds begin to germinate at 4°C. The optimum temperature is 15-20°C. The germination is slow at high temperatures. At the same time, the celery seeds need more moisture and certain light to germinate.

Celery seedlings can be sown several times a year throughout the year depending on the region. For example, nursery seedlings are usually planted in mid-June to August and late January to February in Hangzhou. Among them, during the period of January-February, seedlings were planted in an amount of about 250 grams per mu. The film was used to cover seedlings and the seedling age was 50-60 days. From mid-June to July, the seedlings were raised and the amount of mu was about 0.5 kg. The seedlings were shaded and seedlings were used. Age 40-50 days; in August, seedlings, about 250 grams per mu, shade seedlings, seedling age of about 50 days.

Since the celery seed (actually fruit) is small, the pericarp is thick, the water permeability is poor, the seedling ability is weak, and the seed germination requires a relatively low temperature. Therefore, the seeds need to be properly treated before seeding to accelerate seed emergence. Usually soaking for 12-14 hours, then rinse with water, hand scrub, remove the epidermis, to dry the seed surface moisture, and then germination at a holding temperature of 20-22 °C, until 50% of the seed germination can be seeded . The bottom water should be poured before sowing, and the shade should be protected from rain during the hot season. About 7-14 days after sowing, the seedlings emerged. After emergence, the bed soil should be kept moist, and the groundwater should be poured as a principle. Seedlings can be planted when they have 4-6 true leaves. Due to the long time of celery emergence, weeds often appear in seedbeds and weeds should be removed from the seedlings with 1-2 leaves.
