The difference between North Atractylodes lancea and Guan Atractylodes lancea

1, different morphological characteristics:

The head of Atractylodes macrocephala is born at the top of the stem tip, with needle-like leaflike bracts at the base, long comb-shaped edges, slightly shorter than the head flower, cup-shaped involucres with 7-8 rows of involucres, hairs, tubular flowers and white corollas. Achenes are long, densely silvery white, and the crown hairs are feathery. The rhizome is hypertrophy and nodular.

The stem of Atractylodes lancea is unbranched or branched and hairless. The basal stems and leaves wither and fall off at flowering stage. Lateral lobes elliptic, obovate, long obovate or oblanceolate. All the leaves are thin, like paper, with the same color on both sides, green and hairless. The edge of the lobe or the edge of the lobe is acicular, and the leaves at the lower part of the inflorescence are almost sessile. Needle-like pinnate fissure. The involucre is bell-shaped, all bracts are blunt and round at the top, and the florets are yellow or white.

2. Different producing areas: Atractylodes lancea is mainly produced in western Liaoning, and Atractylodes lancea is mainly produced in eastern Liaoning.

3. The flowering and fruiting period is different: the flowering period of Atractylodes macrocephala is July-August, and the fruiting period is 8-65438+ 10. The flowering and fruiting period of Atractylodes lancea is August -65438+ 10.

1, seed characteristics

The physiological characteristics of Atractylodes macrocephala seeds are basically the same as those of Atractylodes lancea, and their life span is short. Stored at room temperature, the life span is only 6 months, and the seeds cannot be used every other year. Cryopreservation can prolong the life of seeds. Seeds stored at 0℃-4℃ for 65438 0 years can keep the germination rate above 80%.

Atractylodes macrocephala seeds belong to low temperature germination type, the lowest germination temperature is 5℃-8℃, and the optimum temperature is 10℃- 15℃. When the temperature is higher than 25℃, the germination of seeds is inhibited, and when the temperature is higher than 45℃, almost all seeds are moldy. Because Atractylodes lancea seeds belong to low germination type, autumn sowing is better than spring sowing in production.

2. Reproductive characteristics

When the seed germinated and unearthed, it was two true leaves, and the hypocotyl expanded and gradually formed roots. With the growth of the plant, the leaves are increasing, and the seedlings before withering 1 year are rosettes, and the fresh weight of roots is 3-6 grams. 2-year-old plants began to form aboveground stems, and the rhizome was oblate and 2-2.8 cm long, and 1-5 regenerated buds grew on the rhizome, with fresh weight of10-15g; The 3-year-old plants began bolting and flowering, and the roots became thicker and longer, weighing about 25 grams.
