In the endless hills and mountains of North China，You can often see patches of jujube trees standing tall in the wind。Jujube trees grow into a forest，Green shadow whirling。Jujube has accompanied Chinese civilization through thousands of years of vast history，There is a poem in "The Book of Songs": "Cooking sunflowers and bean sprouts in July，Peeling dates in August，Harvest rice in October，For this reason, spring wine is a good way to promote longevity..."，Su Qin also described it this way when he was lobbying the Yan State during the Warring States Period: "Yan... there is Jieshi Yanmen in the south，Bei Youli Zhili，Although the people do not work as tenants，I am satisfied with Zaoli，This is called Tianfu。”Thousands of years，People grow dates、Research on jujube、Eating dates in different ways、Song Zao、Drawing jujube...the legend about jujube、Story、Poetry、Prose、Drama、Idiom、Painting、Photography、Sculpture、Songs, etc.，Abound。In addition，Jujube culture is also reflected in politics、Economy、Philosophy and all aspects of social life。Jujube trees and war、&Policy、With famous people from ancient and modern times；Jujube trees and agriculture、With Industry、bet365 online casinoWith tourism；Jujube trees and daily life、Inextricably linked to customs and sentiments，Leaves traces of jujube culture everywhere。Jujube，Leaving its graceful figure in the long history of China，has entered various fields of human social life，And is an integral part of Chinese culture。
Qing Dynasty poet Cui Xuyou wrote a poem: "Autumn day in the autumn forest on the river，Red Beads on Branches。A long-waisted woman carrying a basket，The jujube pole is twenty punches long”，Another poet wrote, "The spring breeze has passed and the autumnal equinox has begun."，The sound of beating jujubes can be heard across the distance。One hundred thousand trees for three or two people，The clouds on the roof of the field are red”，Every August of the lunar calendar、Golden Autumn Season，The sight of the jujube harvest is like hearing its sound，It’s like watching the scenery。Exquisite and simple poem，It shows a vivid picture of the Chinese jujube culture for thousands of years。
Thousands of years of history、The great waves have washed away the sand until today，The status of jujube trees in China’s agricultural and forestry economy remains undiminished。Jujube industry is an important economic pillar industry in my country，Plays an important role in the national economy，Currently our country has the global96% of jujube resources and98% of international trade in jujube products，Having an absolute dominant position in the world。Jujube tree has become the largest dry fruit tree species in my country，It is also an important national industry for farmers to get rid of poverty and increase income。Since the reform and opening up,The area of jujube trees and jujube production in my country have nearly doubled3Fan, prices are generally rising steadily. along with21The arrival of the century,Join in our countryWTO、Western Development、Agricultural industrial structure adjustment、Western Development、Under a series of major historical scenarios such as returning farmland to forest，my country’s jujube industry is facing new opportunities and challenges。
In this context，The problems existing in my country’s jujube industry have become increasingly prominent: the extensive business model leads to annual20%～30%’s jujube forest is harmed by harmful organisms，The annual loss is more than billions of yuan。If we can break through the key technologies for efficient ecological regulation of jujube forests，will bring huge improvement and further development space to the jujube industry。However，Realizing high efficiency in jujube forests、Ecological regulation is not easy，Related research has become a major problem in the field of agriculture and forestry industry research。
bet365 online sports betting liveMeanwhile，Industrial civilization continues to impact the development of traditional culture and traditional industries，How to continue to keep the jujube industry and jujube culture young and show new characteristics in the new era，This is a question that Wang Younian’s team has been thinking about and exploring in depth。
Create a prosperous modern jujube industry
In view of the development bottleneck of my country’s jujube industry，Wang Younian’s team began to vigorously carry out research，Face the difficulties，Strive to break through this development bottleneck。They are supported by national and provincial science and technology plans，After many years，With scientific research institutes、Related enterprises and other departments jointly tackle key problems，Respectively from experimental design、Forest research、Indoor experiment、Regional Demonstration、Proceeding from multiple aspects such as ecological control of harmful organisms，Conducted research on the "Research and Demonstration of Key Technologies for Efficient Ecological Regulation of Jujube Forests"，Achieved important scientific and technological innovation。As understood，This project integrates pomology、Fruit Ecology、Multi-disciplinary high-tech research and demonstration such as comprehensive pest control of fruit trees。
They are studying the harm caused by harmful organisms in jujube forests，Created and improved the database of harmful organisms and their natural enemies in jujube forests。Constructed a new method for pest investigation, reporting and control，Significantly improves the accuracy of efficient ecological regulation and management of jujube forests。According to different seasons and phenological characteristics of jujube forest，Innovated the key technology system for efficient ecological regulation of jujube forests。In addition，They also discovered an environmentally friendly new substance to control pests in jujube forests，Laid the foundation for the development of natural active substances and efficient ecological regulation of pollution-free jujube forests。This research project has been fully recognized and highly praised by the industry for its application of ecological regulation theory in the comprehensive management of harmful organisms in jujube forests。
Reporters discovered through novelty checking and retrieval，Although some research has been carried out at home and abroad on the efficient ecological regulation of jujube forests，But the entire jujube forest composite ecosystem has never been considered as a whole，Systematic study of the distribution of harmful organisms、Occurrence and quantity increase，Discuss the theory and bet365 online sports betting mobilekey technologies of efficient ecological regulation of jujube forests。
The research of Wang Younian’s team，Fills the gap very well。Through the overall understanding and research of the jujube industry，They created a promotion and application system for efficient ecological regulation of jujube forests，Overcoming the disadvantages of blind use of chemical pesticides，Changed Zaolin’s traditional business model，Solved the major bottleneck problem of harmful organisms in jujube forests that has always restricted the development of jujube trees，Improved the quality of jujube fruit and the level of environmental protection，Achieved significant economy、Ecological and social benefits，Made great contributions to the production of pollution-free jujube fruits。At the same time，Their efforts in the field of jujube industry，It also promoted the development of related industries，If it promotes the progress and improvement of the fruit tree industry，And maintains my country's advantages and leading position in efficient management of the fruit tree industry with leading technology。
During the research process of the project，Wang Younian’s team is united，Work together，They are not doing scientific research in the orchard，Just immersed in the laboratory。In order to obtain research results as soon as possible，All team members voluntarily give up their rest time during holidays，Traveling back and forth to the grassroots，A large number of problems were discovered and solved in a timely manner。They used side surveys、side test、Bian Research、Side demonstration、Methods of edge promotion，Finally developed simplicity、Yixing、Efficient、Economy、Key technologies for safe and efficient ecological regulation of jujube forests。After the application of this technology，Achieved significant economy、Ecological and social benefits。
Today，With the joint efforts of the entire research team，Red dates are hanging on the branches，More abundant than ever。After the project won the award，Wang Younian attributes all glory to the collective efforts of the team。He said: "Everyone adds firewood and the flames are high，Unity and collaboration are the basis for success。Develop jujube industry and jujube culture，For carrying forward the national spirit and reviving the national culture，Also has a positive meaning。”
Wang Younian’s team looks forward to the development of my country’s jujube industry with higher yields and higher quality、The development path of ecologically healthy modern agriculture continues to move forward，We also look forward to the revival and development of Chinese jujube culture by taking advantage of the development of jujube industry。
