Gansu is the largest province in China for cultivation of Chinese herbal medicines. In 2014, the planting area has reached 3.8 million mu, and the output has exceeded 760,000 tons. The varieties of Angelica, Astragalus, Codonopsis, Rhubarb, and Glycyrrhiza are known as “Five of Gansu Chinese Medicineâ€. "Golden Flower" has become one of Gansu's characteristic and advantageous industries. In order to continue to expand the planting scale and planting quality of local Chinese medicinal materials, the local government began to start with breeding and actively promoted the construction of the Chinese herbal resources germplasm resource pool. Through the investigation and collection of these excellent Chinese herbal medicine germplasm resources, the development of the breeding work was conducted. Resources are available to develop more excellent seed seedlings. At present, the development of Chinese herbal germplasm resources is becoming more and more important in areas where Chinese herbal medicines are cultivated in larger areas. The reason why these regions strongly support the construction of Chinese herbal germplasm resources pool is mainly because we need to establish a set of perfection. The standardized Chinese herbal germplasm resource management system allows more excellent Chinese herbal medicine genes to be used by us and will not die out because of human influence and social changes, thereby causing regret and loss for the development of the Chinese herbal medicine industry. At the same time, vigorously support the construction of the germplasm resource pool of Chinese herbal medicines. This technology can be used to provide accurate seed production, standardized production standards and excellent seed seeds for the production of Chinese herbal medicines in Gansu Province and even the whole country. The stability and high quality of the supply of raw materials for Chinese herbal medicines. At present, in terms of the germplasm resources of Chinese herbal medicines in Gansu Province, there are many types of Chinese herbal medicines in Gansu Province, with large yields, distinctive features, and outstanding resource advantages. Therefore, the use of germplasm resources to ensure the conservation and utilization of these Chinese herbal germplasm resources can promote the sustainable development of this characteristic and advantageous industry of traditional Chinese medicinal materials, and at the same time, promote the local people to grow Chinese medicinal materials, vigorously develop the Chinese medicinal material industry, and increase income. Get out of poverty.
