Praise the emperor's golden silk and long dates first. The fruit is big and high quality. When it is half dry after ripening, you can pull out golden sugar silk. The famous and famous products of Zanchang Jujube Group have been planted in Zanhuang County for 400-600 years (45%).
Second, Zanhuang similar jujube is one of the main varieties in Zanhuang jujube group, accounting for 45% of the cultivation ratio. It is as famous as Zanhuang long jujube and can also pull out golden sugar shreds. Its biological characteristics, stagnation period and adaptability are the same as those of jujube.
Third, praise the new jujube. After Ouzao was introduced into Xinjiang, due to the change of natural conditions, the ecological variety of Ouzaosi jujube group was formed. Zanxin Jujube was named by experts at the China Jujube Record Review Meeting held in Changsha, Hunan Province in October1983+/kloc-0. "Zan" refers to Zanhuang Jujube, and "Xin" refers to Xinjiang, which means Zanhuang Jujube settled in Xinjiang. Zanxin jujube was introduced by Xinjiang Zhikesu Alar Agricultural College. After Zanhuang jujube was introduced into Xinjiang, it was influenced by the special climate in this area: high temperature in summer, cold in winter, long sunshine time, large temperature difference between day and night, low relative humidity, less annual precipitation, but good irrigation conditions. Therefore, the growth, fruit and fruit quality of Zanhuang jujube in Xinjiang surpassed that of Zanhuang County, the country of origin. (1) variety.
Golden jujube.
(2) Site conditions.
Altitude 100 m to 450 m, the soil parent material is granite and gneiss, and the soil is cinnamon sandy loam with pH value of 6.5 to 7.5.
(3) Cultivation management.
1. Seedling raising: scions are collected from selected excellent plants and grafted with jujube as rootstock to ensure the purity of varieties.
2. Seedling planting: after defoliation, before soil sealing in winter or after thawing in the following spring, to budding stage, dig planting holes or ditches, apply sufficient fertilizer, and plant with a planting density of 83 plants/m2.
3. Shaping and pruning: adopt trees with more main branches such as natural shape, small crown and sparse layer shape, spindle shape, etc., to ensure that the tree body is ventilated and transparent, the skeleton is firm, the number of branches is appropriate and the structure is good.
4. Harvesting: Jujube fruits are harvested when the skin is purplish red, slightly wrinkled, the flesh is soft and yellow-brown. Natural drying or drying after harvest. When the water content is lower than 25%, it will be stored in stages.

2. Physical and chemical properties: total sugar ≥65%, protein ≥2.8%.
