Ruoqiang County is located in the hinterland of Eurasia and the east of Tarim Basin, with a typical warm temperate desert and arid climate. Ruoqiang Oasis faces Taklimakan Desert and backs Altun Mountain. It is located between 86 45'-93 45' E and 36 05'-465 438+0 23' N, with an altitude of 846-4,500m. Annual average temperature 1290, annual average precipitation 3 1.2 mm, annual average evaporation 2902 mm, annual sunshine hours 3 103.2 hours, accumulated temperature ≥ 10℃, 4396. 8℃. Frost-free period 198.7 days, with an annual average relative humidity of 39%. The climate is dry and hot, the illumination time is long, the daily temperature difference is large, the photosynthetic effective radiation is extremely high, and the light and heat resources match perfectly, which is very suitable for planting high-quality jujube.

Jujube is a light-loving tree species, and the influence of light on dry matter accumulation and fruit quality of jujube is extremely obvious. The annual total radiation 147.5 kcal/cm in Ruoqiang County is 2 years, and the photosynthetic effective radiation in the growth period of jujube trees is 73.7 kcal/m for 2 years, which is higher than that in Chinese mainland jujube production area and ranks first in Xinjiang, which is beneficial to dry matter accumulation and fruit quality improvement. The accumulated temperature of jujube trees from germination to maturity ≥0℃ is 3200-3750℃, and that of Ruoqiang County ≥0℃ is 39 10℃, which is much higher than the temperature requirement of jujube trees in the growth period. The large temperature difference between day and night is beneficial to the accumulation of nutrients in jujube fruit. Generally, during the fruit growing period, the daily temperature range is above 12℃, and the fruit grows fast, but below 1290, the growth speed slows down. The fruit growth period of Ruoqiang jujube is from June to September, which is the period when the daily temperature difference in Ruoqiang County gradually increases, with an average of 17℃, especially in the middle of August in Ruoqiang County, when the temperature difference between China and Japan is the largest, with an average daily temperature difference of17.5-10/8.2℃, the highest.

Ruoqiang jujube was introduced in 1970s, and 1988 was introduced and planted in an organized way. By 2000, there were 14 10000 jujube trees in the county. In 200 1 year, in order to further accelerate the strategic adjustment of rural industrial structure and greatly increase the income of farmers and herdsmen, Ruoqiang County Party Committee and County People's Government established and implemented the "Development Strategy of Jujube Industry in Ruoqiang County", with the goal of building the best dried jujube base in China. By 2004, the planting area of red dates in the county reached 70,000 mu (more than 7.5 million plants). In 2003, the jujube eco-economic forest construction project in Ruoqiang County was named as the seventh landmark project of rejuvenating Xinjiang through science and technology by the office of rejuvenating Xinjiang through science and technology for standardized production and management. In the same year, Ruoqiang "Loulan" jujube was selected as a brand-name agricultural product in Xinjiang by the Xinjiang Agricultural Brand Product Identification Committee. June 2004 +2004 10, Ruoqiang's "Loulan brand" jujube won the first prize of China jujube quality products at the "First National Selection Meeting of High-quality Fresh Jujube and Jujube Processed Products" held in Xi 'an. All these have laid a solid foundation for Ruoqiang County to build the best dried jujube base in China.
