酸枣原产我国,是北方几省常见的野生果树。自古以来就有“荆棘遍地”、“披荆斩棘”的说法,荆是牡荆,即马鞭草科的荆条(Vitex negunda),棘就是小枝多刺的酸枣。现在这两种植物在华北干旱荒山上仍是随处可见。李时珍在《本草纲目》中也指出棘就是酸枣。1108年宋代重修的《欧和本草》有大枣和酸枣的形态图,图上的酸枣,刺多、叶小、果实圆,与现在的酸枣形态相似,而大枣即是现在的栽培枣。关于酸枣的植物学名称,有些学者把栽培的枣树定为一个种(Zizyphus jujuba Mill),酸枣作为其变种(Z. j. var. spinosus),我们认为从大枣与酸枣的亲缘关系上看,大枣是通过人工选择,从酸枣中选出来的。因此,酸枣应该是栽
Jujube origin of our country, is a common wild fruit trees in several provinces in the north. Since ancient times, there have been “thorns everywhere,” “clogged thorns” argument, Jing is the Vitex, Verbenaceae Vitex negunda, spines is prickly jujube. Now these two kinds of plants are still everywhere in the drought hills in North China. Li Shizhen also pointed out in the “Compendium of Materia Medica” that spine is jujube. 1108 Song Dynasty rebuilt the “European and Herbal” jujube and jujube morphological map, jujube, spines, small leaves, fruit round, and now the shape of the jujube, Jujube is the current cultivation of jujube. On the botanical name of jujube, some scholars regard cultivated jujube as one species (Zizyphus jujuba Mill) and jujube as its variant (Z. j. Var. Spinosus), and we think that from the genetic relationship between jujube and jujube , Jujube is by manual selection, picked from the jujube. Therefore, jujube should be planted
