银杏,其名出自《本草纲目》。因中果皮为白色,故又名白果;因叶形状像鸭掌,又俗称“鸭脚”;因其结实周期过长,故又称之为“公孙树”。银杏是我国特有的经济树种。而今我国年产白果5000余吨,约占全世界总产量的90％。射阳县数年前就开发银杏,现有银杏园林约三千亩,其中黄光锁和新洋乡各有一个千亩成片银杏园。目前长势旺盛,即将挂果。银杏树在我国栽培历史悠久,早在汉末三国时,江南已有种植,宋朝时,黄河流域已普遍栽培。银杏是果树中首屈一指的“寿星”,眼下结果累累的千年古树在我国尚存1300多抹。陕西省周至县楼观台,有株古老银杏树,树龄已达2000年左右,长安
Ginkgo biloba, whose name is from the “Compendium of Materia Medica”. Because the mesocarp is white, it is also known as ginkgo; because the shape of the leaf is like a duck’s paw, it is also commonly known as the “duck’s foot.” Because of its long fruiting cycle, it is also known as the “Kung-sun tree.” Ginkgo biloba is a unique economic tree species in China. Today, China produces more than 5,000 tons of ginkgo, accounting for about 90% of the world’s total production. Sheyang County developed Ginkgo biloba several years ago. There are about 3,000 mu of Ginkgo biloba gardens. Huang Guangsuo and Xinyang Township each have a piece of ginkgo garden. The current strong growth is about to bear fruit. Ginkgo biloba has a long history of cultivation in China. As early as in the late Han and the Three Kingdoms, Jiangnan has been planted. In the Song Dynasty, the Yellow River Basin has been widely cultivated. Ginkgo biloba is the second-largest “life star” in the fruit tree, and now there are more than 1,300 wiped-out millennium ancient trees in China. Louguantai, Zhouzhi County, Shaanxi Province, has an ancient ginkgo tree, its age is around 2000, Chang’an
