The latest course of sprouting techniques and methods of celery

Celery sowing material is fruit, because the skin is thick and strong, and has oil glands, impervious to water, slow and irregular germination, sowing in summer and autumn is more difficult, so before raising seedlings or direct seeding in summer and autumn, we need to soak seeds to promote germination. Let's take a look at the technology of accelerating germination of celery.

Soaking seeds in clear water to accelerate germination

Soak the seeds in clean water for 24 hours to fully absorb water, then knead and rinse the seeds several times until the water is clear, spread the seeds on the grass mat and dry them slightly in a cool place, losing too much moisture on the seed surface, put the dried seeds in an earthen basin, cover with a wet cloth, and put them in a cool and ventilated place to promote germination. The suitable temperature for germination is 15: 20 ℃. During the germination period, the seeds are turned once a day to make the temperature and humidity uniform. Wash the seeds with clean water twice every 2 days to prevent mildew. After washing, hang it for a while, and then continue to sprout. In about 7 days, more than 80% of the seeds can be sown when they are white.

Soaking seeds in Minshui to accelerate germination

Put the seed into a cloth bag, soak it with Minshui and lift it into a well, about 30 centimeters from the water surface, so that it can absorb water and expand in a low-temperature and humid environment. 24 hours later, take back and release Xuan to promote germination under the condition of 15: 20 ℃, the temperature should not be too high, in order to prevent budding Shenguan Dongqi or cause the radicle slender. Rinse with clean water 2 / 3 times a day, and 80% of the radicles are exposed in 2 / 3 days before sowing.

Low temperature treatment to accelerate germination

After soaking, the seeds were refrigerated at 0: 1 ℃ for 3 days, and then germinated at 15: 20 ℃, which could shorten the germination time and improve the uniformity of germination. Soaking seeds with gibberellin or 1% thiourea of 100ppm can replace low temperature treatment and achieve the same effect.
