Why is winter jujube called winter jujube?

Winter jujube generally ripens naturally in the solar calendar from 65438+ 10 to 165438+ 10. Because the weather in the north entered the cold earlier, it was named "Winter Jujube".

Dongzao (also known as Yanlaihong, Apple Jujube, Rock Sugar Jujube, Huanghua Dongzao, Miaoshang Dongzao and Zhanhua Dongzao) is a high-quality late-maturing fresh food species in northern Shandong.

Red dates are different from winter dates. Jujube is sweet in taste, high in nutritional value and crisp, so it is not suitable for storage. It is all dried and used for storage. Winter jujube can be stored for about 3 months, which is not easy to deteriorate and has a long sales cycle. Jujube is usually dried and sold, which can be used to make cakes and snacks.

The history of winter jujube

Dali County, Shaanxi Province, formerly known as Tongzhou, is located in the hinterland of Qinling Mountains, where Wei, Luo and Huang meet. Known as "the first county of winter jujube" and "the hometown of jujube in China". There were jujube trees in Dali more than 2,000 years ago, and jujube trees were planted everywhere in the Western Han Dynasty. During the reign of Kangxi, Dali Dongzao has become a royal tribute, which shows that Dali Dongzao has a long history.

Backed by the Loess Plateau and facing the rolling river, the soil here is mainly clayey and rich in organic matter. The area belongs to warm temperate semi-humid and semi-arid monsoon climate, with an average annual temperature of 65438 03.4℃, long annual illumination time, less rainfall and large temperature difference between day and night, which is very beneficial to nutrient transformation and sugar accumulation of winter jujube.
