Because Anqing, Anhui Province is hot and rainy in summer and mild and humid in winter, it belongs to the north subtropical humid monsoon climate zone. Geomorphology can be roughly divided into Zhongshan, low mountains, hills, terraces (hills) and plains. However, Lycium ruthenicum is mostly distributed in alpine sand forest, salinized sand land, along rivers and lakes, in dry riverbed and desert riparian forest, and it is a unique desert medicinal plant species in western China.
Lycium ruthenicum
Black Lycium barbarum is black fruit Lycium barbarum. The Mongolian name of Lycium ruthenicum is "Jonoying-Halmag" and the Tibetan medicine is "Pangma", which belongs to Lycium genus of Solanaceae. It is a spiny shrub with many branches and hard branches, often zigzag and white. Distributed in China, Qinghai, Xinjiang, Gansu, Europe and Central Asia.
morphological character
Spiny shrub, 20-50 (- 150) cm high, with many branches; Branches oblique or lying on the ground, white or grayish white, hard, often zigzag, with irregular longitudinal stripes, twig tips tapering into spines, internodes shortened, each node with short spines, 0.3- 1.5 cm long; The short branches are located on both sides of the spine, and the young branches are not obvious. The old branches are tumor-shaped, with clustered leaves or flowers and leaves at the same time. The old branches are short branches, with tumor-like processes and no leaves. 2-6 leaves are clustered on the short branches, and the single leaves on the young branches are alternate, plump and fleshy, subsessile, banded, banded or oblanceolate, sometimes narrowly lanceolate, rounded at the top, tapering at the base, and sometimes slightly rolled down at both sides. The midvein is inconspicuous, 0.5-3cm long and 2-7mm wide. 1-2 peanuts on short branches; Pedicel thin, 0.5- 1 cm long. Calyx is narrow bell-shaped, 4-5 mm long, slightly hemispherical when the fruit expands, surrounded by the middle and lower parts of the fruit, irregularly 2-4-lobed, with membranous lobes and sparse cilia at the edge; Corolla funnel-shaped, light purple, about 1.2 cm long, tube slightly expanded to the eaves, 5-lobed, lobes oblong or oval, about 1/2- 1/3 as long as tube, hairless and inconspicuous; Stamens slightly protrude from corolla and are inserted in the middle of corolla tube. There are sparse hairs on the filaments slightly higher than the base, and there are also sparse hairs on the inner wall of the corolla. The style is almost as long as the stamens. Berries are purple-black, spherical, sometimes slightly concave at the top, 4-9 mm in diameter, and the seeds are kidney-shaped, brown, 1.5 mm long and 2 mm wide. The flowering and fruiting period is May-65438+1October.
growing environment
Lycium ruthenicum distributed in alpine sand forest, saline-alkali sandy land, rivers and lakes, dry riverbed and desert riparian forest, is a unique desert medicinal plant species in western China. Wild Lycium barbarum has strong adaptability, can tolerate the high temperature of 38.5 degrees Celsius, has strong cold resistance, has no freezing injury at -25.6 degrees Celsius, is drought-resistant, and can still grow in the desert. It is a light-loving tree species, which thrives in full light, grows weakly in shade, and has few flowers and fruits. Not strict with soil requirements, salt and alkali tolerance, drought tolerance.
distribution range
Scattered in Jiuquan, Gansu, China, western Qinghai, Xinjiang, western Inner Mongolia and Tibet. It grows in barren hills, riverbeds and beaches where human beings can't live, and it has strong vitality. However, with the development of nature, the living space of Lycium barbarum is getting smaller and smaller, which has created this rare and precious original ecological advanced nourishing product.
