History of winter jujube
Dali County, Shaanxi Province, known as Tongzhou in ancient times, is located in the hinterland of Qinling Mountains, where the three rivers of Wei, Luo and Huang meet. It has always been known as "the first county of winter jujube" and "the hometown of Chinese jujube". Jujube trees were planted in Dali more than 2,000 years ago, and jujube trees were planted everywhere in the Western Han Dynasty. During the Kangxi period, Dali winter jujube has become a royal tribute, which shows that Dali winter jujube has a long history.
Backed by the Loess Plateau and facing the rolling river, the soil here is mainly clayey soil with rich organic matter. The land belongs to warm temperate semi-humid and semi-arid monsoon climate, with annual average temperature 13.4℃, long annual light hours, less rainfall and large temperature difference between day and night, which is very beneficial to nutrient conversion and sugar accumulation of winter jujube.
