Jujube is a traditional jujube tree in China. It has records on red dates in the Chinese literature "Book of Songs" and "Compendium of Materia Medica". Jujube is a deciduous tree with strong adaptability. It is a pioneer species suitable for cultivation in barren wasteland. It can withstand temperatures up to 43 ° C in summer and -33 ° C in winter. The soil pH value is between 5 and 8.6, and the jujube can grow normally. At the same time, the long-standing natural forests and artificial ancient forests have strong soil water holding capacity. In the plateau area where the vegetation is sparse, on the slopes along the Yellow River, these physiological characteristics of jujube seedlings are of great significance in wind and sand fixation, soil and water conservation, and water conservation. Today, I will introduce to you the distribution of red jujubes in China: The distribution of our jujube production areas is extremely broad, with a distribution area of 75-125 degrees east longitude and 19-43 degrees north latitude. The northern margin of the distribution area is from Shenyang and Chaoyang in Liaoning Province in the northeast, Zhangjiakou in Hebei, Ningcheng in Inner Mongolia, Nanhao in Hohhot to Baotou Daqing Mountain, Lingwu in Zhongning, Zhongning in Ningxia, and Linze in the Hexi Corridor in Gansu. Dunhuang, until the south of Changji in Xinjiang to the south of Guangxi, Pingnan, Guangdong, and other places; the west to Xinjiang, Kashgar, Aksu, Korla and other places; the most east to Liaoning's Benxi and the eastern coastal areas. The middle and lower reaches of the Yellow River have a long history of cultivation in the jujube area. It is the origin of jujube and the most important jujube cultivation area in China. The output accounts for more than 80% of the national total output. The cultivation area is a warm temperate semi-humid area. The hilly jujube area on the Loess Plateau belongs to the warm temperate arid area. The jujube area in the arid zone of the northwest belongs to the temperate arid zone. Southern District: This area refers to the Huaihe River and the area south of the Qinling Mountains. The Jianghuai River alluvial soil jujube area belongs to the north subtropical zone. The southern hilly jujube area refers to the hilly area south of the Yangtze River and is located in the mid-subtropical zone and the southern subtropical zone. Sichuan, Guizhou, and Yunnan jujube areas include the Sichuan Basin and the Yunnan-Guizhou Plateau, which is the edge of the southern fauna.
