Yafei Gems

The first hybrid celery seeds have vigorous growth, bolting resistance, petiole not easy to hollow, good disease resistance, and strong adaptability. The stalks are yellow-green, compact columnar, 70-80cm tall, high yield, and first-class commodity.

Main cultivation measures:

For seedling cultivation in the low temperature season, it is generally necessary to soak the seeds for sprouting, soak the seeds in clear water for 12-24 hours, the germinating temperature is 15-20℃, and cover with fine sand 1cm or fine wet soil 0.5cm after sowing. The rear cover film is required to maintain moisture and keep the soil temperature at 15-20℃. For sowing in high temperature seasons, dry seeds are usually used to direct seedlings. After sowing, cover with thin grass curtains, etc., and gradually reduce the shade after emergence. After emergence, the water absorption capacity of the seedlings is poor, and it is necessary to water frequently with small water, reaching 2-3 leaves for thinning. After that, the border surface will see dry and wet, and it can be planted up to 3 leaves and 1 core or 4 leaves and 1 core. The planting density depends on the size of the variety itself and the demand for the size of the product. For large trees (over 2 kg), it is 30 cm×30 cm, and medium trees (1～1.5 kg) are 30 cm×20 cm. 25 cm × 20 cm. Only reasonable dense planting can achieve the goal of high quality and high efficiency. After planting, the temperature during the day is generally maintained at 15-20 ℃, and at night 5-10 ℃, try to make the night temperature not lower than 5 ℃. The height of the seedlings is about 15cm, and the topdressing and watering are started when the ridges are closed. 15-20kg of ammonium nitrate or 25-30kg of ammonium sulphate is used per mu each time. The next 3-5 days are called watering once, and the water is applied in 15-20 days. 1 time fertilizer. It can be harvested after 50-60 days.

Adaptability:

It is recommended to sow from July 10 to September 10 in Hubei, and from June 10 to July 10 in Hangzhou, Zhejiang. Spring sowing in Guanzhong area of Shaanxi is from November 15th to February 5th, and autumn sowing is from June 10th to July 20th.

risk warning:

Pay attention to heat preservation in spring seedlings to avoid bolting. Pay attention to prevent leaf spot and soft rot in the autumn growth period.

This species is a hybrid, and cannot be reserved.
