The reason why Chaoyang jujube is unique in quality and famous all over the world, in addition to the excellent varieties and scientific cultivation methods, the unique natural conditions are the decisive factor.　　Geographic location is unique: chaoyang county belongs to the western Liaoning hilly area, geographic location east longitude 119 ° 52 ′ -120 ° 47 ′, north latitude 40 ° 55 ′ -41 ° 54 ′, is located in our country jujube cultivation area delineated within the northern boundary line. Dwelling in the north temperate continental monsoon climate zone, although the southeast by the ocean warm humidity, but due to the northern Mongolian plateau of dry cold air often invasion, the formation of a half-dry, half-humid valley area, with seven mountains, one water, two fields of geographic features. This unique geographical environment is very suitable for the growth of existing varieties of Chaoyang jujube.　　Temperature, light, precipitation conditions: Chaoyang belongs to the north temperate zone continental monsoon climate zone, the average temperature throughout the year is about 5.4 ℃ to 8.7 ℃, the average annual sunshine hours for 2850 ~ 2950 hours, the annual precipitation 450 ~ 580 mm. 4-9 months early growing season weather warm, sunshine, rainfall is moderate, distribution is uniform, is China's cultivation of jujube the best climate area; 5-8 months jujube tree The main growing season temperature of jujube is more than 3600℃, which is the first one in each jujube area in China; the four seasons are clear, drought and little rain, the temperature difference between day and night is big, and the annual average evaporation is 4.3 times of rainfall, which is favorable to the accumulation of sugar, and creates the sweetness and crispness of the Chaoyang jujube.In June, the average temperature of 25.2℃ during the period of jujube blossom is the optimal temperature for the blossoming of the Chaoyang jujube, which ensures the stable and high yield. Less rain, very conducive to Chaoyang jujube flesh sugar color, reduce rain crack and berry, increase the quality rate of Chaoyang jujube.　　Soil conditions: Chaoyang County is located in the hills of western Liaoning mountains, the soil is mainly sandy loam, the soil layer is more than 200cm, PH value is 7.2-8.4, good aeration, there is a certain degree of water retention capacity, providing necessary water for the growth of jujube trees. Different jujube area soil, titanium, cobalt, zinc, iron and other trace elements content is obviously different, chaoyang jujube production area of titanium, cobalt, zinc content is higher than other areas, titanium, cobalt, zinc and other trace elements in the soil content situation, for the improvement of quality of chaoyang jujube provides a relative potential supply capacity and storage environmental conditions.　　Chaoyang County, this unique location, climate and soil conditions, created Chaoyang jujube excellent quality, after years of cultivation and development, Chaoyang jujube has become one of the county's pillar industries of rural economy and the main channel for farmers to increase income, the market reputation is very good. 2011 May 13, the State General Administration of Quality Supervision, Inspection and Quarantine issued the Announcement No. 70 of 2011, according to the "Geographical Indication Product Protection Provisions".
