There are also news reports that Cao Fuliang, president of Nanjing Forestry University and president of China Ginkgo Research Association, said after a field trip to Wulong County and Jiangbei District of Chongqing, "Chongqing's natural conditions such as light, water resources and heat are suitable for planting ginkgo. This point can be proved by Chongqing's possession of ancient ginkgo for one or two thousand years. " Cao Fuliang said that Ginkgo biloba is afraid of water and should not be planted in places where the groundwater level is too high. Ginkgo biloba should be planted in soil at least 1 m deep to survive better. Ginkgo biloba has a strong ability to resist disease, drought and radiation, and its vitality is also strong. The terrain of Chongqing is suitable for the growth of ginkgo biloba. More medicinal materials can be planted on Kangmei Chinese Medicine Network to communicate with drug dealers all over the country.
