Longxi: Do a good job of "chip" of Chinese medicinal materials 赓 赓 赓 赓 赓 赓 赓

In recent years, the Gansu Provincial Herbal Given Resource Library has been made to preserve rare and endangered Chinese herbal medicines, promote the selection and standardized cultivation of new Chinese herbal medicines as a breakthrough, and scientifically store the quality of Chinese herbal medicines. It still has the original genetic characteristics and high germination rate, which provides a seed seedlings with accurate source, production specifications, and excellent species for Chinese herbal medicine production.

In the gene room of Longxi Medicine Garden, Li Guangwen, a technician of the Longxi County Agricultural Technology Promotion Center, and colleagues are conducting DNA extraction experiments on astragalus blades. DNA barcode technology is a research hotspot widely used in the classification and appraisal of Chinese medicinal materials in recent years. It is a technique for species appraisal and classification through a section of DNA fragments.

Li Guangwen, a technician of the Longxi County Agricultural Technology Promotion Center: In order to further preserve, develop and excavate the variety resources of Chinese medicinal materials, Longxi Pharmaceutical Garden carried out research on the DNA technology of Chinese medicinal materials last year. The development of this technology can better distinguish the authenticity and confusion of Chinese medicinal materials, and the operation is relatively simple, the identification is accurate, scientific, and highly automated. At the same time, the development of molecular biology experiments helps us to excavate the genes of Chinese medicinal materials and conduct research on related molecular biology tests.

In the group cultivation laboratory, technicians are conducting overwintering tissue, irregular bud proliferation, and nonsense breeding tests of Epimedium buds, petioles, and stem stalks. In the later period, it will also conduct an improvement test of the types, concentrations, and time of the disinfection agent, and strive to make breakthroughs in the shortest time. Longxi Pharmaceutical Garden is cultivated in accordance with the development of biological group cultivation, accelerating the cultivation of Chinese medicinal materials, establishing a sterile seedlings system for Chinese medicinal materials, and separating the body resources of wild valuable Chinese medicinal materials such as Dendrobium candidum and departure varieties.

Tian Yanlong, a technician of the Longxi County Agricultural Technology Promotion Center: Our plant organization cultivates a large amount of rapid breeding of plant growth environment, increasing plant resistance, and achieving valuable Chinese medicinal materials and endangered varieties. On the other hand, it is also an effective way to protect the plant germ quality in a large amount of safely protecting the plant germs under the conditions of smaller space and artificial control.

In 2019, Longxi Yaoguiyuan relied on the construction of Chinese herbal quality resource resource preservation and research base construction projects in Gansu Province. It has initially built the Gansu Provincial Herbal Given Resource Library with 60,000 libraries and a construction area of ​​about 1120 square meters. Including one short -term, medium and long -term library 67.80 square meters each, the laboratory is 123.14 square meters, the training room is 67.7 square meters, the specimen room is 120 square meters, and the live body preserves 60 acres. Build multi -functional resource libraries such as Chinese herbal germplasm resources, organizational cultivation, seed QR code traceability platform, Chinese herbal medicine DNA extraction, DNA barcode sequence, DNA barcode database and other multi -functional resource libraries. At present, 86 2,300 species of Chinese herbal medicine (mainly seeds), more than 1,600 wild resource specimens, 120 kinds of genetic spectrum, 1,800 pieces of Chinese herbal medicine DNA barcode sequence information.

Zhang Jinwen, a technician of the Longxi County Agricultural Technology Promotion Center: Gansu Province's Chinese herbal medicine germplasm resource library is the protection base of the germplasm resource resource protection of regional traditional Chinese pharmaceutical materials facing the northwest. Rare, endangered, unique resources and local varieties, and carry out the identification and evaluation of varieties through genetic testing and expert appraisal, and finally developed varieties with high medicinal value and great contributions to the development of the Chinese medicinal materials industry. application.
