Hetian jade jujube, as its name implies, is produced in Hetian, Xinjiang, the hometown of beautiful jade silk. The planting base is the most famous "fruit eugenics area" in the world. Hotan area is located between 36 59 ′ 50 ″ and 37 ″ north latitude14 ′ 23 ″, which is recognized as a "fruit eugenic area" by world fruit experts. Hetian Yuzao 300,000 mu pollution-free planting production base is located at the northern foot of Kunlun Mountain and the southern edge of Taklimakan Desert, at this latitude. Petite jujube seedlings went from Yuanjia, the main producing area in the mainland, to Hotan, Xinjiang, and turned into graceful Hetian jade dates, which were made in this way:
Soil: the vast sandy soil without pollution is the guarantee of natural jujube.
Sunshine: the average daily sunshine is as long as 15 hours, and the photosynthesis of jujube trees is more sufficient.
Temperature difference: the temperature difference between day and night is nearly 20 degrees, which makes the nutrients of red dates stored more.
Frost-free period: the frost-free period of more than 220 days throughout the year makes the ripening time of red dates more abundant.
Irrigation: the irrigation of ice-clean snow water in Kunlun Mountain for thousands of years has enriched the mineral content of jujube.
Natural pollution-free breeding environment
These rare natural environments and unique climate in the mainland make fruit trees free from pests and diseases, and jujube trees do not need to be sprayed with any pesticides, creating a natural and pollution-free cultivation environment for the growth of "Hetian Yuzao".

Natural ecological environment and human and historical factors
(1) Soil landform: The soil type in the planting area is mainly brown desert soil, and its physical and chemical characteristics are as follows: the brown desert is covered with gravel, and the profile also contains gravel of different sizes and quantities, and the vegetation coverage on the surface is extremely low and almost bare.
The planting area is located at the northern foot of Kunlun Mountain, and the landform belongs to the piedmont gravel inclined plain. The terrain is high in the southwest and low in the northeast, and it slopes from southwest to east with a slope of 2.5‰.
(2) Hydrological conditions: Jujube has the characteristics of drought resistance and waterlogging tolerance. Kalash River (hereinafter referred to as Kalash River), as the only surface water resource in reclamation area, originates from Kunlun Mountain and Karakorum Mountain, and its recharge source is mainly meltwater of ice and snow, supplemented by rainfall. The average annual runoff is 710.48 billion cubic meters, and the average flow is 69.5 m3/s, which is irrigated by Israel's advanced drip irrigation technology.
(3) Climatic characteristics: It belongs to a typical continental climate, with scarce precipitation, drought and windy weather, large temperature change, large temperature difference between day and night, and large annual temperature difference.
According to the data of Mo Yuxian Meteorological Station, the annual average temperature in the planting area is 12. 1 degree, the average temperature in July is 24.4 degrees, the average temperature in 1 month is -6 degrees, the extreme maximum temperature is 42.7 degrees, and the extreme minimum temperature is -23.7 degrees.

Now it is mid-April.
(4) Human and historical situation: Since the opening of the Silk Road in the Western Han Dynasty, Xinjiang has been reclaimed and reclaimed in past dynasties. After thousands of years of gradual introduction and planting, jujube has gradually formed a unique jujube variety in Hami, Hotan, Kashgar, Aksu and other Gobi desert areas. Hetian was called "Yutian" in ancient times, and was once called Anxi four counties together with Shule, Anxi and Qiuci in history. It is the southernmost city in Xinjiang, and it is also an important place for human activities south of the Silk Road. Jade articles, BMWs, melons and fruits from the Western Regions spread to the Central Plains, and the silk from the Central Plains was continuously transported to the Western Regions from here. As early as the Shang and Zhou Dynasties, ancient Khotan had material exchanges with the Central Plains. In 68 BC, Xuan Di, Emperor Gaozu of Han Dynasty, "sent troops to guard the countries west of Shanshan", and Khotan was formally brought under the jurisdiction of the central government of Han Dynasty. Guhetian is the earliest Buddhist center in the Western Regions, and it has rich Buddhist cultural heritage. Many famous monks, such as Faxian in Jin Dynasty and Xuanzang in Tang Dynasty, have set foot in Hotan. Hotan has a warm climate, rich specialties and simple folk customs, and is known as "the hometown of gold and jade, the warehouse of grain and cotton, the Silk Road, and the hometown of melons and fruits". Tan is recorded in Liang Shu. "There is plenty of water and sand, and the temperature is suitable for rice, wheat and peaches. China people are good at bronzes, fruits, vegetables and porcelain. Sui Shu's Biography of the Western Regions says: "This place is rich in hemp, wheat, millet, rice ... and many gardens." Xuanzang also said in "Records of the Western Regions of the Tang Dynasty" that "it is appropriate to grow crops and melons". Peach, apricot, sour plum and other stones were unearthed from the ancient tomb of Pulu in Luopu Mountain (Warring States to Three Kingdoms). Fruits such as peaches, apricots, grapes, pears and Elaeagnus angustifolia were found in the Niya site in Minfeng County. _ Lu Wen also recorded the pomegranate unearthed in Jingjue (now Minfeng County). These records and unearthed cultural relics confirm that horticulture in Khotan is very developed.
Hotan area now governs Hotan City, Hotan County, Pishan County, yutian county, Mo Yuxian, Luopu County and Qira County.
Lexian County, Minfeng County and the 14th Division of the Corps. Qira county has a long history of planting red dates in ancient times. Jujube mainly includes Zan jujube, Huizao jujube, Zizyphus jujuba, Jixin jujube and Simiao jujube, but the planting scale is not large, and it is just a fresh fruit for Uighurs. After liberation, due to the unique geographical location, the advantages of light and heat resources and the soil conditions suitable for the growth of jujube trees in Hotan area, the planting scale of jujube trees has developed greatly. Especially in recent years, with the deepening of the adjustment of agricultural industrial structure, the state has implemented the strategy of "developing the western region" and increased its investment in forestry. The 14th Division of Corps regards the development of jujube as an important measure of industrial structure, firmly grasps the policy and opportunity, and develops the characteristic forest and fruit industry on a large scale, which makes the jujube planting industry develop to a new level. Hotan area has the characteristics of long sunshine, strong radiation, high accumulated temperature and large temperature difference, which makes its fruit big, sweet and excellent in quality, and enjoys a high reputation in the fruit market at home and abroad. Hetian Yuzao also won the gold medal in the second China (International) High-level Forum on Jujube Industry Development.
