China is the origin of jujube in the world. The middle and lower reaches of the Yellow River, as one of the origins of the Chinese nation, is the earliest cultivation center of jujube trees in China. In ancient times, the main source of food for people was wild fruit, and jujube was recognized by humans for its delicious taste in many wild fruits.
The global important agricultural cultural heritage Shandong Leling Zaolin Complex System is the only original jujube forest with the longest cultivation history and the best quality. It is also the jujube forest complex system with the largest area, the largest number of plants and the best preservation in China. The millennium jujube tree is cold-tolerant and windy, still leafy and full of fruit, and is called the living fossil of jujube.
a long history of jujube culture
Leling City is located in the north of Shandong Province, adjacent to the Binzhou and Shandong Peninsula urban agglomerations in the east, Hebei and Tianjin Binhai New Area in the north, Jinan Metropolitan Area in the south, and the Dezhou section of the Xilian Jinpu Railway in the south. It is the northern gate of Shandong Province and the main gateway to Beijing. It has the title of “Qiyan Fortress” and “Luyi Hub”. It is 44.5 kilometers away from Bohai Bay and has the geographical advantage of “North-South borrowing power, east and west source”. The Leling jujube forest compound system area is located here, covering an area of 500,000 mu.
As early as 284 BC, the famous Yan Guoyi Leyi brought the jujube to the land of Leling. In the Qin and Han Dynasties, the Leling jujube on the east coast was covered with a mysterious coat of “Xiandaohua”. During the Wei, Jin and Southern and Northern Dynasties, the population of Leling has increased dramatically, and the natural environmental conditions have been deteriorating. The jujubes can be used as food after drying. In the age of eating, it is an important food for the local people. The jujube varieties have been improved, and the varieties that are both drought-resistant and infertile are selected to continue to be planted in large quantities. The original mysterious jujube trees have entered the homes of ordinary people.
The ecological value of Leling jujube forest is extraordinary. The Leling jujube forest compound system has the function of improving the environment, can effectively reduce the wind speed, play the role of wind and soil fixation, adjust the temperature and humidity, and reduce the evaporation rate. It can improve the soil environment. The litter of jujube forest can improve soil texture and aeration, and increase soil water holding capacity and organic matter content. It has improved the dry and barren soil environment, provided a living environment for other organisms, enriched the system’s biodiversity, enhanced the stability of the system, and increased the circulation rate of the material and energy of the system.
Leling jujube culture is rich. The Tang Dynasty poet Li Wei “April south wind barley yellow, jujube flowers have not fallen in the shade of the long”, another famous poet Liu Changqing poetry in the Tang Dynasty “walking through the mountains and hills, the room is red and underground”, Song Dynasty poet Zhang Wei Written in “Jujuan Gua Tian Jing Yu Liang, white shirt black hat wild man costume”, Qing Dynasty poet Wu Taipang wrote “June fresh lotus even water Bi, thousand small jujube shoot cloud red” good sentence. Contemporary poets are even more admired “in the long autumn winds, the mother-in-law is a tree of red beads.” Through these poems, you can enjoy the scenery of Leling Zaoxiang and the feelings of contemporary people.
Jujube pulls out “golden wire”
The main agricultural products of Leling Zaolin Complex System are Jinsixiaozao. Leling Jinsi jujube is generally oval and goose-shaped, with small nuclear skin, full flesh and delicate meat. The fresh jujube is bright red, the meat is crisp, sweet and slightly sour; the dried jujube is dark red, the meat is thin and tough, and the wrinkles are shallow. After the dried golden silk jujube is opened, it is often seen that there is a silk thread between the flesh, and sometimes it can be stretched one or two inches. In the “Qi Min Yao Shu” written by Jia Wei, the Northern Wei Dynasty, he wrote: “The fine muscles of the muscles are rich, the cream is more fat, and it is the best in the world.”
Leling people integrate culture into the “jujube core” and improve the quality of jujube industry development. In recent years, Leling has registered the geographical indication certificate of Leling Jinsixiaozao, and has supported a number of jujube enterprises with good market prospects, high technology content and great development potential, focusing on capital, land and information. The company is inclined to promote the expansion of the scale of the enterprise and the upgrading of the product grade. It has formed a large number of jujube processing enterprise groups, and also introduced Huiyuan Group, a leading enterprise in the juice beverage industry. Its jujube juice product digests 1800 tons of Leling jujube.
At present, there are more than 100 small jujube processing enterprises in the city, including 46 enterprises above designated size and 23 foreign exchange earning enterprises. The processing conversion rate of jujube has reached 42%. It has developed eight series of more than 120 kinds of jujube products such as jujube wine, jujube tea, jujube juice, jujube, crystal jujube and gelatin jujube. In the year, it received 500,000 tourists and gradually transformed from “selling products” to “selling brands”, “selling tourism” and “selling culture”.
Protection and development
On the basis of the research on the system management of the Leling jujube forest system, Leling took multiple measures to protect, develop and utilize this article.
Leling divides the protection of jujube forest system into three protection levels: core zone, buffer zone and radiation zone. The millennial jujube trees in the core area are long in age, concentrated in resources, and the ecological environment is relatively stable. The buffer zone provides services and tourism products for tourists; the radiation zone leaves room for the construction and production of jujube products and leisure agriculture.
Comprehensively strengthen the management of jujube trees. According to the Millennium Jujube Tree archives, the existing jujube trees will be comprehensively verified, and the lost and damaged ancient tree cards will be repaired in time. The Millennium Jujube will be identified according to the administrative village, and the village cadres will be the first responsible person for the protection of ancient trees in the administrative area. The jujube planting professional cooperatives assisted in the supervision and signed the responsibility letter of responsibility for the households.
Expand the amount of jujube resources. Improve irrigation traffic conditions, cultivate new jujube ecological parks, vigorously develop new jujube planting bases of local varieties, standardize production procedures in accordance with green food and pollution-free production standards, improve product quality, and ensure the safety and health of jujube. Expand the amount of resources and materials, and lay the foundation for the deep processing of jujube fruit products and the expansion of jujube industry.
From the original cultivation of the squats, the better preservation and the gradual attention to the present, the tourism activities have played a big role. The picking festival held by the fruit of the jujube compound system is more famous around the world. It has played a big role in the local rural landscape and people’s thinking changes.
Establish a professional full-time forest protection team. Coordinate the agriculture and forestry departments, set up special funds for jujube development and protection, and through careful selection and study and training, gradually establish a group of professional full-time forest protection teams in the local area, and clarify the duties and responsibility areas of forest rangers. In addition to supervising and guiding farmers’ management, record and monitor the growth cycle, pests and diseases of jujube trees, inherit and improve traditional techniques, study new management methods of ancient trees, and provide technical support for the rejuvenation and planting management of millennium jujube trees.
