The leaves are alternate, and the lower leaves of the stems are 2-3 odd-pinnate, with a petiole 10-20 cm long, and the bases are hung on both sides of the stem. Leaflets 3-4 pairs, ovate-lanceolate, 2-lobed on leaflets, terminally lobulate with unequal serrations, thin leaves, dark green on surface, pale green on surface abaxially, glabrous; inflorescence apically Health or axillary, total umbrella stems 10-15, ranging in length, rough surface, no total lice, small umbellules about 20-30 flowers, etc. 5 pieces, lobes triangular; petals 5, white obovate, apex pointed Inward folding; male; this 5, filaments thin, curved, anthers elliptic, 2-loculed; styles 2, shortly reflexed, ovary ovoid, lower 2 locules. Double hanging fruit oval smooth and hairless, dorsal ribs and midribs winged, side wings without wings, ribs asked usually 3-4 tubal, combined with 5-6 tubal surface. When the fruit matures, it splits into two fruit and hangs at the top of the two fruit columns. The flowering period is 8-9 months and the fruiting period is September-October. Resource distribution: Born in forest margins, under shrubs, and in grass valleys at elevations of 2000-4200 m above sea level. Distributed in Shaanxi, Gansu, Qinghai, Sichuan, Tibet and other places. (2) Wide-leafing livelihood: also known as E-living Perennial grasses, 80-100 cm high, erect rhizomes. Stem base purplish red, with vertical grooves on surface, glabrous, hollow, lower dog stem, 2 or nearly 3 pinnate compound leaves, petiole 7-19 cm, base scalloped, amplexicaul; leaflet final culm ovate Shaped lanceolate, 2-4 cm long, 1-2 cm wide, apex acuminate, margin irregularly pinnately dehiscent; stem upper leaves gradually reduced to purple leaf secondary, both surfaces glabrous, only below leaf veins Slightly hairy. Umbrella inflorescence densely many flowers, small umbellate as long or slightly shorter, flowers, etc. 5, narrowly triangular; petals 5, yellow, ovate-lanceolate, 2 mm long, 0.6 mm wide, apex acuminate, inflexed Vol.; male; this 5 alternates with petals, anthers elliptic, filaments soft, incurved; ovary inferior 2-celled, styles 2, very short. Double-hanging fruit, with 6 wings, dorsal ribs and the wing of the Lieutenant Colonel, wingless wings, joints facing the inner back. Fruit and fruit period from July to August. 羌 live hi cool and humid climate, cold. In the mountains in September when the surface of the next sentence is still frozen chlorophyll; seedling fear of light, hi fat, with acidic, neutral soil is appropriate. Alfalfa can either be seeded or rooted. From May to the end of June each year, the aboveground part grows rapidly and can grow 70-100cm in height in one month. The annual growth period decreases with increasing altitude. The longest period is about 110 days, and the shortest is about 90 days. Due to the short growing period, the live roots and rhizomes grow slowly. It takes 3-5 years or longer to germinate from seeds to grow into commercial products. Resource distribution: Born in forest margins and shrubs at an altitude of 1700-4500m above sea level. Distributed in Inner Mongolia, Shanxi, Shaanxi, Ningxia, Gansu, Qinghai, Hubei, Sichuan and other places. (3) Chuanxiong live Herbs perennial, 60 to 100 cm tall. The rhizomes are thick and the internodes are extremely short. Stem base often purple, with vertical grooves on the surface. The lower leaves of the stem are 3 out of 2 pinnate compound leaves, about 30 cm long, sometimes up to 60 cm; petiole is about half full length, with fine ribs, base sheathing; leaflets pinnate, lower first leaflets Stem, often sessile, lobes lanceolate or ovate, with sharp or obtuse ribs on edges, glabrous on both surfaces. Umbrella terminal or axillary, total umbrellas 15 to 20, with branches, smooth, no genus; small total ridge linear; caries 5; petals 5, yellowish green, obovate, apex narrowly introductory; Stamens 5; style base projecting, stigma 2. Double-hanging fruit is broadly ovoid, with dorsal and midribs well-developed, wings, side wings without wings, and rib grooves with 3 to 4 sleeves. Flowering from July to August. 2. Geographical distribution and ecological environment The livelihood is cool and damp, and it grows at high altitude. The topographic and climatic features of Qinghai Province form the two natural habitats of the Gannan Plateau and Qilian Mountain. (l) Gannan plateau living area: Gannan plateau is located in the southwest of Qinghai, most of which are more than 3,000 meters above sea level. The climate is cool and humid, cold and cool in summer, with an average annual temperature of 2-rc and precipitation of 550-750 mm. Word 10. C accumulated temperature in 1200. C-2000. C. The soil is brown earth and subalpine shrub meadow soil. The alfalfa livelihood is mainly distributed in the broad-leaved forests and grasses of alpine shrubbery at an altitude of 1,600 to 3,000 meters above sea level in Diebu, Lintan, Zhuoni, Luqu and Xiahe. Broad-leaved larvae live in Maqu: 1700-3500 meters of grasses and shrubs in Xiahe, Luqu and other places. There are also a small number of lizi, Zhuoni and Diebu. (2) Qilian Mountain habitat distribution area: Qilian Mountain is located on the northern edge of the Qinghai-Tibet Plateau, and the eastern section is relatively humid. Northern Tombs at an altitude of 2,500 meters above sea level are the main growth areas for Alpaca. The annual precipitation is 400-800 mm, and the annual average temperature is below 2. C, Yun 10. C accumulated temperature in 2000. C Below, dryness is less than 1. Plants have long-grass, donkey donkey high, cold swing, carex, grass, rhododendron, ghost arrow Caragana and Qinghai spruce, pine, poplar, birch and other tall plants. The soil is mountain ash-calcium soil, mountain forest gray cinnamon soil and so on. The area is mainly lived in the alpine undergrowths, shrubs, or grasses of Zhule, Maozang, Xidatan, Harbin, and Sunan counties in Tianzhu County, followed by the Dalin and Changlin in Gulang County. There are also distributions in areas such as Imperial City, Fufeng, and Dahe in Sunan County.
