在20世纪的最后几年,全国范围内出现了“银杏热”,由山东、江苏等银杏产地为主,老产区遍及20余省（市、区）,发展势头极其迅猛。但1998年以来,银杏产品市场却出现波动,银杏叶提取物4500元/kg 跌至1800～2000元/kg,银杏种子由48～70元/kg跌至 16～40元/kg。银杏价格落差很大,使人不能不怀疑:银杏还能不能发展?白果还能不能“红”起来?
In the last few years of the 20th century, “Ginkgo fever” emerged in the whole country, with the origin of Ginkgo biloba in Shandong and Jiangsu provinces dominated. The old producing areas covered more than 20 provinces (cities and districts) and the momentum of development was extremely rapid. However, the market of ginkgo products fluctuated since 1998, with Ginkgo biloba extract falling to 1800-2000 yuan / kg and Ginkgo biloba dropping from 48-70 yuan / kg to 16-40 yuan / kg. Ginkgo price gap is great, people can not help but doubt: Ginkgo can not develop? Ginkgo can not “red” up?
