How much does a jin of Apiaceae celery seeds cost? Detailed explanation of germination and seed quantity per mu
Celery, also known as wild celery, water celery, etc., is a relatively common Apiaceae vegetable in our country. Because it has a special aroma like cilantro, it is widely used as a seasoning, and with its rich content of vitamins and trace elements, it is quite favored by people. So how much does a jin of celery seeds cost? How long does it take to germinate? How many seeds are needed for one 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, and different varieties will also have certain differences in price. Regional differences also lead to different prices for celery seeds, so everyone should still refer to local prices.
How long does it take to germinate?
Under suitable temperature conditions, celery seeds can germinate in 7 to 10 days. The minimum temperature for celery seed germination is 4°C. The most suitable temperature is 15 to 20°C. Below 15°C, the germination time of the seeds will be prolonged. Above 25°C, the germination rate decreases significantly. Above 30°C, they almost do not germinate. Below 30°C, the greater the temperature difference, the higher the germination rate. Alternating temperature treatment at about 25°C for 6 to 8 hours and about 15°C for 16 to 18 hours.
The germination rate is relatively high. Under suitable temperature conditions, they can germinate in 7 to 10 days. At the same time, seed germination must also have sufficient moisture. They need moisture and cannot tolerate dryness. Generally, a moisture content of 70% to 80% is better. Sufficient oxygen is also needed.
How many seeds are needed for one mu of land?
The amount of celery seeds needed per mu of land is about 300 grams.
Attached celery seed germination acceleration techniques:
Soaking seeds in clear water to accelerate germination
Soak the seeds in clear water for 24 hours so that the seeds fully absorb water, then rub the seeds and wash them several times until the water is clear. Spread the seeds on a straw mat in a cool place to dry slightly, so that excess moisture on the surface of the seeds is lost. Put the dried seeds in a clay pot, cover with a wet cloth, and place in a cool, ventilated place to accelerate germination. The suitable temperature for accelerating germination is 15-20°C. During the germination acceleration period, turn the seeds once a day so that the temperature and humidity are uniform. Wash the seeds twice with clear water every 2 days to prevent mildew. After washing, let them dry slightly, then continue to accelerate germination. After about 7 days, when more than 80% of the seeds have broken through the seed coat, they can be sown.
Soaking seeds in well water to accelerate germination
Put the seeds into a cloth bag, moisten them with well water, and hang them into a well about 30 cm from the water surface, so that they absorb water and swell in a low-temperature, humid environment. After 24 hours, take them back and place them under 15-20°C conditions to accelerate germination. The temperature must not be too high, to prevent uneven germination or slender radicles. Rinse with clear water 2-3 times a day. After 2-3 days, when 80% of the radicles are exposed, they can be sown.
Low-temperature treatment to accelerate germination
Refrigerate the soaked seeds at a low temperature of 0-1°C for 3 days, then place them under 15-20°C conditions to accelerate germination, which can shorten the germination time and improve germination uniformity. Soaking the seeds in 100 ppm gibberellin or 1% thiourea can replace low-temperature treatment and achieve the same effect.
Hormone germination acceleration
Some varieties of seeds have a 1-2 month dormant period after harvest. If newly harvested seeds of the same year are used for germination acceleration, sprouting is often difficult, and the sprouting time is long and uneven. Therefore, 5 mg/L gibberellic acid can be used, with each 20 mL ampoule added to 4 kg of water, soaking the seeds for 12 hours, then removing them for sowing; or soaking the seeds in 1000 mg/kg thiourea solution for 10-12 hours; the seeds can also be refrigerated for 30 days; some also use 800-1600 mg/L high-concentration gibberellic acid to treat the seeds, which can shorten the germination time and increase the germination rate.
Alternating temperature germination acceleration
After the seeds are soaked, place them in a 15-18°C incubator. After 12 hours, raise the temperature to 22-25°C. After another 12 hours, lower the temperature to 15-18°C. After about 3 days, they sprout and can be sown.
