Wild carrot: alias: wild carrot tassel, mountain carrot; Annual or perennial herbs. Distributed in Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei, Sichuan, Guizhou and other China areas; It is distributed in Asia, Europe and North Africa.
Roots are fleshy, conical and nearly white. Stem height 15 ~ 120 cm, solitary and erect. Basal leaves are papery, rectangular, pinnately divided for two or three times, and lobules are strip-shaped to lanceolate, with a length of 2 ~ 15 mm and a width of 0.5 ~ 2mm；; Petiole is 2 ~ 12 cm long and sheathed; Basal leaves subsessile, lobules slender. Compound umbel is terminal, with total peduncle length10 ~ 60 cm; There are many involucral bracts; Involucral bracts 5 ~ 7, strip-shaped, indehiscent or pinnately divided; Flowers are white or red. Rubus is oblong, 3 ~ 4 mm long, with 4 edges and short grooves on its wings. Cell chromosome: 2n= 18.
Wild carrot overwintering seeds were sown in the following spring and emerged from mid-March to mid-June. In warm temperate and subtropical regions, the green body of seedlings planted in autumn overwinters and turns green from the end of February to the beginning of March of the following year. Then it takes root quickly, with clustered leaves, shoots and branches in mid-April, budding in mid-May, blooming from late May to early June, and fruit ripening from late July to early August, with a growth period of about 160d, which is not reproducible. It can be used for 2-3 times before branching, and the number of times cannot be too many, otherwise it will seriously affect the growth and development of regeneration. Wild carrots have strong adaptability and like to grow in fields, roadsides, ravines, hilly slopes and idle wasteland around residential areas. Generally, it is scattered, but sometimes it can form a dominant community and become a pioneer community of vegetation succession on abandoned farmland or loose rake grassland. Wild carrot is a positive plant and likes to grow in sunny open areas. Under dark conditions, growth and development are poor.
Wild carrot stems and leaves are tender and juicy, which is a good green feed. Pigs like to eat, cattle and sheep like to eat, and chickens, ducks and geese all eat. However, after flowering, the stems and leaves are aging, the palatability is poor, and the nutritional value is obviously reduced, so all kinds of livestock and poultry do not eat them. But that prepare hay powder can still be use. In the chemical composition of wild carrots, the crude protein content is 10.96% of dry matter, the crude fat is 1.9 1%, the crude fiber is 3 1.94%, the nitrogen-free extract is 48.45%, and the crude ash is 6.74%. Both calcium and phosphorus are less. Its total energy, digestibility, metabolic energy and crude protein content for pigs, chickens, cattle and sheep are relatively high, and it belongs to medium forage. Wild carrot stems and leaves can be used as green feed, sun-dried green hay, silage or hay powder for compound feed. Fleshy roots and seeds are also good for juicy feed and concentration.
