In today's rapid economic development, people in all walks of life are facing different degrees of tension and pressure, and the number of sub-health people is increasing. For the sub-healthy state of real discomfort but no obvious lesions, the health concept of medicinal and food homology shows great advantages. China has become an important raw material supplier and commissioned producer of the world's functional food industry, and the safety and tonicity of medicinal and food homologous substances have unique advantages in the process of internationalization of traditional Chinese medicine, and are a sharp sword that transforms China's resource advantages into industrial advantages. The following is a kind of medicinal and food homologous vegetables.
1. Variety profile
Potentilla chinensis Ser., alias Azure Dibai, is a plant of the genus Rosaceae. It is produced in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Shanxi, Shaanxi, Gansu, Shandong, Henan, Jiangsu, Anhui, Jiangxi, Hubei, Hunan, Taiwan, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan and Tibet. It is found in the Russian Far East, Japan, and Korea. It grows under meadows, ravines, forest edges, shrublands or sparse forests on hillsides at altitudes of 400-3200 m.
2. Morphological characteristics
It is a perennial herb. The roots are stout, cylindrical and slightly woody. The flower stems are erect or raised , sparsely covered with short soft hairs and long white silky hairs. The basal leaves are pinnate compound leaves, small leaves are paraphyletic or alternate, oblong, inverted ovate or oblong lanceolate, marginal pinnate mid-lobe, lobed triangular ovate, triangular lanceolate or oblong lanceolate. Umbel-like polyumbel inflorescence, with lanceolate bracts at the base and densely covered with short soft hairs on the outside; triangular ovate sepals, banded or lanceolate, yellow petals, broad inverted ovate, slightly concave at the apex, slightly longer than sepals; the flower peduncle is nearly apical, slightly papillating or inconspicuous, and the stigma is enlarged. The fruit is ovoid, dark brown and has obvious wrinkles. The flowering period is from April to October.
3. Main value
The root of Weiling cai contains tannin, which can be used to make quercetin; the whole herb is medicated, which can clear heat and detoxify, cool the blood and relieve pain. It is used for abdominal pain of red diarrhea, long-term diarrhea, hemorrhoid bleeding, carbuncle sore poison. The young seedlings are edible and can be used as pig feed. The young stems and leaves (seedlings) or roots of Weiling vegetables, also known as cabbage, root head vegetables, tiger's claw vegetables, spring picking young seedlings, summer and autumn picking whole grass, washing fresh use, the whole grass can also be dried and prepared, can be used for weiling vegetable hibiscus flower soup, root head vegetable soup, etc., the party has the effect of clearing heat, detoxification and healing sores. For the initial onset of a boil carbuncle, pain and burning.
4. Plant non-test tube efficient and fast propagation technology
In contrast, in the large-scale planting of Weiling vegetables, the use of plant non-test tube efficient and rapid propagation technology (TERNPC) invented by researcher Li Changxiao will undoubtedly accelerate the industrialization process of Weiling vegetables. The technology only requires one leaf and one bud, the material is simple, and the time to root into seedlings is greatly shortened. On the whole, the plant non-test tube efficient and fast propagation technology invented by researcher Li Changxiao is used to carry out asexual and fast propagation of Weiling vegetables, which can produce large-scale rapid reproduction without variation, low cost, short cycle, large scale and industrialization, and quickly supply seedlings to all sectors of society.
Plant non-test tube efficient fast propagation technology is a new plant cloning system, completely out of laboratory conditions, simple nursery facilities. Compared with tissue culture, the fast propagation input is dozens of times lower, which greatly saves germplasm material than conventional seedlings, and the amount of explants used to propagate the unit material is 3 to 8 times less than that of conventional seedlings; the inoculation speed is extremely fast, which is 3 to 5 times that of tissue culture, and the labor efficiency is extremely high. Through the investment in the use of plant non-test tube efficient and fast propagation technology, the investment can be increased geometrically in the short term, which can drive the common development of many enterprises and individuals and create more economic benefits for investors.
