How much is the celery seed of Umbelliferae per jin? How long will it sprout? How many seeds do you need per mu of land?

Celery, also known as parsley and water celery, is a common umbrella plant vegetable in China. It is widely used as a seasoning because of its special aroma with parsley, and it is very popular with people because it is rich in vitamins and trace elements. How much is the celery seed? How long will it sprout? How many seeds do you need per mu of land?

Celery seed price:

The market price of celery seeds is about 50 to 60 yuan per jin. There are many varieties of celery seeds, different varieties will have certain differences in price, regional differences also lead to differences in the price of celery seeds, we still take the local price as standard.

How long does it take to sprout?

Celery seeds can germinate in 7 to 10 days under suitable temperature conditions. The lowest temperature for celery seed germination is 4 degrees Celsius. The most suitable temperature is 15 to 20 degrees Celsius. It's less than 15 degrees Celsius. The time of seed germination will be prolonged, the germination rate above 25 degrees Celsius decreases significantly, and there is almost no germination above 30 degrees Celsius. When the temperature is below 30 degrees Celsius, the greater the temperature difference, the higher the germination rate. To 25 degrees Celsius for 6 to 8 hours, 15 degrees Celsius for 16 to 18 hours of temperature change.

The germination rate is higher. Under the suitable temperature condition, it can germinate in 7 to 10 days. At the same time, there must be enough water for seed germination. Need to be wet and not resistant to dryness. The general water content should be between 70% and 80%. And we need enough oxygen.

How many seeds do you need per mu of land?

The amount of celery seeds needed per mu is about 300 grams.

The techniques of accelerating germination of celery seeds are attached.

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.

Hormone accelerates germination

The seeds of some varieties have a dormant period of 1-2 months after harvest, such as using the new seeds harvested in the same year to accelerate germination, it is often difficult to sprout, and the budding time is long and irregular. Therefore, gibberellic acid can be used with 5 mg / L gibberellic acid, 20 ml each with 4 kg of water, soaking the seeds for 12 hours, or soaking the seeds with 1000 mg / kg thiourea solution for 10 minutes for 12 hours, or refrigerating the seeds for 30 days. some of the seeds were treated with 800 mg / 1 1600mg / L gibberellic acid, which could shorten the germination time and improve the germination rate.

Sprouting by changing temperature

After soaking the seeds, put them in a 15 ~ 18 °C incubator, raise the temperature to 22 ~ 25 °C after 12 hours, lower the temperature to 15 ~ 18 °C after 12 hours, sprout in about 3 days, and then sow.
