A study of global ecological adaptability and field selection practices of Panax ginseng

Through the development of ecological suitability analysis of producing area and the selection criteria of farmland cultivation in the global range of ginseng, we aim to provide scientific basis for rational planning, production layout and standardized planting of farmland. We analyze the data based on the ecological factors from 271 sample plots of Panax ginseng, including both the traditional producing regions recorded in past dynasties medicinal works and the popular production regions in the world, using global geographic information system for medicinal plant(GMPGIS) developed by ICMM (Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences). We concluded that the suitable producing areas in global for P. ginseng mainly included America, Canada, China, Russia, Japan, North Korea, France, Italy, Ukraine, and South Korea. In addition, the suitable producing areas in China mainly included Heilongjiang, Jilin, Liaoning, Shanxi, Gansu, Hubei, Sichuan, Inner Mongolia, Shandong, and Shanxi. Besides, based on the references and the experience of ginseng-producing and our many years' work on the 1,000-hectare plantation of P. ginseng, we established a standard land selection protocol for cultivation of P. ginseng. The use of GMPGIS to select the most optimum ginseng production regions provides a new scientific basis for introduction, cultivation, tending, protection, cultivation normalization for P. ginseng and the standard land selection protocol would lay a solid foundation for the high quality P. ginseng production.
