补充资料：唐枣树
唐枣树位于山东省无棣县城北5公里信阳乡李楼村。
无棣金丝小枣的栽培历史可追溯到夏商时代，素有“华夏枣都”之称。信阳乡的李楼村至今还生长着唐代栽植的一棵老枣树，主干结九瘿，穿七窍，虬枝交错，枝繁叶茂，硕果累累。村里男女老幼皆尊其为“寿树”，从不折损其一枝一叶，称其果为“寿果”，传说食用一颗可延寿三载。小枣成熟后采摘下来珍藏，四方乡邻常求索为药引子医治疾病。据当地百姓讲，当年赴蟠桃盛会的龙宫虾将，把玉皇大帝恩赐的“天枣”带回龙宫吃光后，剩下的枣核扔在海底，海潮退出，海滩上便长出了枣树，结出了金丝小枣。小枣树耐盐碱，非常适宜于沿海地区生长。小枣含有丰富的营养价值，非常有益于人体健康。1990年10月1日无棣县人民政府为唐枣树立碑铭保护，成为无棣的一大景观。
