Celery conventional seedling raising technology

Germination: Germination started 7 days before sowing. Use 0.25-0.3 kg of celery per mu of greenhouse. When germination, select 10% saline to remove the sclerotia and rinse with clean water. Soak the seeds in 48-degree hot water for another 30 minutes. Be careful to keep stirring and maintain the water temperature. Then put it in cold water for 5 to 10 minutes, then soak in room temperature water for 24 hours. After rinsing the water, wash it several times, gently rub it with your hands, and open the skin until the seeds of the seeds are scattered. Spread the seeds and dry them. When the seed surface is half dry, mix the fine tidal sand with 5 times the seed volume, mix in a clean basin, and cover with a plastic film. Keep in a cool place, 40 cm above the water. That is, under the conditions of 18 to 20 degrees, germination, the fastest germination, the highest germination rate. Delayed germination below 15 degrees, and almost no budding above 30 degrees. Turn it 2 or 3 times a day, soak the seeds by hand and let the seed see light and breathe. Seeds dry to make up water. 7-8 days to sprout.

Preparation of seedbed soil: the seedbed is selected from high-lying, easily-drained plots. The preparation methods for the seedbed soil are 60% for fertile garden soil, 30% for horse dung, 10% for chicken manure or large manure, and 500 g of urea per square meter of nursery bed. Stir and sieve, spread on a seedbed, with a thickness of about 10 cm, and prepare for broadcast.
