Winter jujube usually ripens in autumn in 10- 1 1 month. Some early-maturing varieties can be put on the market in early September, while the extra-late-maturing varieties will be delayed to1late October or even1month. Compared with Zizyphus jujuba, Dongzao is a late-maturing jujube variety, which is smaller than Zizyphus jujuba, with a single fruit weighing about17-25g, a long oblate fruit shape, and the skin color is green and red, and some fully mature skins are bright red, but most of them are green and red. However, Zizyphus jujuba is a tropical and subtropical fruit, with a single fruit weight of more than100g, round fruit shape, smooth and light green skin and similar meat quality to pears.

1. When does the winter jujube mature?

1, the ripening season of winter jujube is 10-1month in autumn. Some early-maturing varieties can be put on the market in early September, while the extra-late-maturing varieties will be delayed to1late October or even1/month. The specific time varies with varieties and regions. In the north of Huaihe River and Qinling Mountains, winter jujubes generally mature in the first and middle days of 10, while extra late-maturing varieties will be delayed to the late days of 10.

2. The reason why Dongzao is called Dongzao is that compared with other fruits, Dongzao tree matures later, and the fruit growth period is more than 120 days, while Dongzao is mainly planted in northern areas such as Shaanxi, Hebei and Shandong, which have entered the cooling season, so it is called Dongzao.

Second, what is the difference between winter jujube and green jujube?

1, morphological characteristics difference

The fruit shape of Dongzao jujube is oblate and long, with a single fruit weighing about17-25g. The skin color of Dongzao jujube is green and red, and some fully mature skins are bright red, but most of them are green and red, with thick meat, small core and much residue. The fruit shape of Zizyphus jujuba is round, its head is bigger than that of Dongzao, its single fruit weight can reach more than100g, its skin is smooth and light green, and its meat quality is similar to that of pear.

2, the origin difference

Dongzao is a late-maturing jujube variety, which is mainly produced in Shanxi, Hebei, Shandong and other places in northern China. Zizyphus jujuba is a tropical and subtropical fruit, which is mainly produced in Taiwan Province and Hainan, and is also planted in Guangdong and Yunnan.

3. Difference of maturity

Winter jujube generally matures in1October, some early-maturing varieties can mature in early September, and the extra-late-maturing varieties will be delayed to1late October or even 1 1 month. Zizyphus jujuba generally matures from 10 to March of the following year.
