Ancient Jujube Trees Resources And Utilization Research In China

Jujube is fruit tree native to china,3000 years of cultural history. Ancient jujube trees are precious resources of our country, have an important production and humanistic value. This research through two yeas of field survey, investigate ancient jujube trees,ancient sour jujube trees resources; distribution; ancient jujube trees cultural; resource utilization; ancient jujube trees production and protection status, into jujube regions of our country.Ancient jujube tree rational utilization and protection provides a theoretical basis. Results are as follows:(1) Ancient jujube trees resources are mainly distributed in the north of china, to date 32 species, 31 varieties of northern, southern species that is only one; by type, 16 varieties of Dried, 5 fresh varieties, dual-purpose breed 10, a candied varieties. More than 300 years ancient jujube trees 10 million lines in china, the max age is located in Shandong QingYun Zhou Yin village of Changhongzao, locally known as Tangzao, about 1400 years. In terms of geographical distribution, Shandong largest number of about 36,772, accounting for 36.9%; in terms of varieties, Jinsixiaozao up to about 35,713, accounting for 35.9%. Sour jujube trees over 300 years about 482 lines, mainly in the Loess Plateau, the Taihang Mountains, Yanshan and Shandong Peninsula. Shaanxi up to about 338, accounting for 70% of china. The max age of Shanxi Province Gaoping shimo sour jujube tree, 2,000 years.(2) Ancient Jujube culture reflected in historical allusion, agricultural heritage and cultural tourism in three aspects. Resource utilization of ancient jujube mainly in breeding and tourism development on two levels, the survey found that China’s ancient jujube There are many types of variation, breeding from 16 ancient varieties of jujube trees in 60 varieties, enriched jujube germplasm resources; tourism development is mainly embodied in eco-tourism, cultural heritage Exposition and three categories for rural development and economic restructuring of the direction. Ancient jujube trees is important wild germplasm resources and potential breeding stock.(3) The study, china ancient jujube area of 1.2% of the national area jujube, jujube production accounted for 5.3%, the output value accounted for 4.4%, has important production value. Ancient jujube difference in the conservation status of each area is large, there are many problems, the need to develop a more scientific and rational management and protection measures.In summary, ancient jujube trees have multiple values, to protect ancient jujube trees is to protect the future germplasm. According to utilization and protection of the status of the ancient jujube trees resources, it recommended the development of ancient jujube resource conservation and evaluation techniques, ancient jujube grading, classification protection; endangered or special ancient jujube set up a special research focus protection; establish germplasm nursery the collection, protection of ancient jujube resources.
