The optimum temperature for celery seed germination is 15-25°C, but it is difficult to emerge when it exceeds 30°C. The seeds can be treated in the following two ways to promote their neat germination.
1. High temperature treatment: After soaking the seeds for 8 to 10 days before sowing, soak in cold water for 24 hours, while changing the water every 8 hours or so. Then knead the seeds and rinse the seeds with water. Drift off the impurities until the water is clear. The seeds were wrapped in gauze and some of the water was squeezed out. Put in the refrigerator, keep the temperature at about 5 °C. Rinse the seeds one at a time with water every morning and evening. After 2 days, spread the seeds in a bright environment and rinse them with cold water twice a day. After each flush, use a fan to blow the seeds for 5 to 10 minutes. Too much water on the seeds is blown away to prevent excessive moisture, resulting in insufficient oxygen and affecting germination. Generally after 5-6 days to germinate.
2, cool treatment: The seeds have been soaked in the first method wrapped in gauze wrap, wrapped, and then hung in the deep well from the surface of the water 40 to 50 cm, washed out with water every day 2 times, after washing The moisture on the surface of the seed should be dried with a fan to increase the oxygen around the seed and then wrapped in the well. After 6-8 days of treatment, germination can be sown. Before seeding, seed dressing with new high-fat film can maintain heat, moisturize and absorb, increase seed germination rate, and make seedlings robust. Repel underground pests and isolate virus infections. Can also be mixed with seed coating agents.
