At the 2010 National Science and Technology Award Conference，A research team headed by Professor Wang Younian, President of Beijing Agricultural College，The "Research and Demonstration of Key Technologies for Efficient Ecological Regulation of Jujube Forests" project that took many years to complete，Won the second prize of the National Science and Technology Progress Award。This project is aimed at the serious insect pests of jujube trees in my country and the urgent need for high-quality and safe jujube fruits in domestic and foreign markets，To balance the protection of the ecological environment and increase the yield of jujube fruit、Quality is the goal，Systematically studied different habitats、Key technical methods and measures for sustainable ecological control of harmful organisms in jujube forests in different intercropping environments，Realized ecological regulation and optimal management of harmful organisms in jujube forests，Transform from passive and blind prevention to active and sustainable ecological regulation，Meet the market demand for safe jujube products。

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，Accompanied by the vast history of thousands of years of Chinese civilization，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 during the Warring States Period also described it this way when he was lobbying the State of Yan: "There are people from Jieshi Yanmen in the south of Yan，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、Song Zao、Huazao、bet365 online sports betting liveStudy dates、Eating dates in different ways，Legends about jujube、Story、Poetry、Prose、Idiom、Painting、Photography, etc.，Abound。Also，Jujube culture is also reflected in politics、Economy、Philosophy and all aspects of social life。Jujube trees and agriculture、With industry、With tourism，With daily life、Customs and sentiments are inextricably linked，Leaving its graceful figure in the long history of China，Has entered all areas of human social life，And is an integral part of Chinese culture。

    Thousands of years of history，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，my country’s jujube resources and international trade in jujube products occupy an absolutely dominant position in the world，Jujube tree is 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。Due to the impact of jujube trees on the environment、Lower soil requirements，Even on barren land，Jujube trees can still grow well，Therefore，For farmers in poor areas，Planting jujube trees has become their biggest economic income。Since the reform and opening up,The area of ​​jujube trees and jujube production in my country have nearly tripled，Price is generally rising steadily。With the advent of the 21st century,my country’s accession to the WTO、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 causes 20%-30% of the jujube forests to be harmed by harmful organisms every year，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 bet365 online sports bettingspace to the jujube industry。However，Achieving this goal is not easy，Related research has become a major problem in the field of agriculture and forestry industry research。Meanwhile，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，It has become a question that Chinese people have been thinking and exploring deeply，Wang Younian and his team have been trudging on this road for 20 years。

January 14, 2011，Under the solemn national emblem in the Great Hall of the People，Professor Wang Younian looks at Dahong’s award certificate，The happy smile was fixed at that moment: 20 years of hard work has paid off，20 years of scientific research accumulation has finally yielded positive results。Looking back at the road we have traveled in the past 20 years，He and his team，Knowing yourself the joys and sorrows。

Early 1990s，Wang Younian led several teachers and students to Luliang, Shanxi Province to start science and technology poverty alleviation work，The expectant eyes of the farmers deeply touched their hearts。That moment，They are secretly determined to help farmers get rid of poverty and become rich。In the process of poverty alleviation，He and several young teachers noticed，Many local farmers plant jujube trees，After soil analysis，They further confirmed，The local poor soil is only suitable for planting jujube trees。So，How to increase the yield of dates，How to avoid the occurrence of pests and diseases，Became the research focus of Wang Younian and several other teachers。Under the guidance and guidance of the older generation of experts，Wang Younian and his team are working on poverty alleviation in Luliang, Shanxi，Beginning of relationship with jujube，Embarked on a long road of scientific research。20 years，They stick together through thick and thin，Traveled to all jujube planting areas and production bases across the country，Go to the fields for investigation and research；Absorb multiple disciplines、Expert professors and young scholars in many fields，Continuously strengthen our scientific bet365 online sports betting liveresearch strength；Although in different units，Different places，But，Ultimately a common goal，Solidarity and collaboration，Tireless，Concentrate on studying。

20 years，They overcome every difficulty，Achieved transcendence again and again，Getting closer to the final result。Early 1990s，Wang Younian led his team to conduct a survey of jujube resource varieties，Conducted extensive research on jujube tree varieties in Beijing and across the country，Understand the growth characteristics of each variety of jujube trees，Laid a solid foundation for the research of this project。Fruit is the main agricultural product in Beijing，There are disadvantages in its production: large demand for fertilizer and water，Severe pests and diseases；Fertilizer、Pesticide input is much higher than that of ordinary crops，Fruit safety is worrying。To the mid to late 1990s，Beijing agriculture is beginning to show the development trend of urban modern agriculture，Start to focus on production、Ecology、Life and other functions。Wang Younian is keenly aware of this trend，led his team to carry out research on the ecological safety of high-quality fruits，In-depth research on the theory and technology of organic cultivation of fruits，Focus on research on key technologies for efficient ecological regulation of jujube forests；Enter the 21st century，The development trend of urban modern agriculture is more clear，People are concerned about food safety、The requirements for ecological security are getting higher and higher，The concept of organic fruits is deeply rooted in the hearts of the people。For this，Wang Younian led the team to conduct systematic and in-depth research on the key technologies for efficient ecological regulation of jujube forests，And achieved certain results。
