A jump-up by a duo tree - the northwestern agroforestry university team relayed the duo resource high-value development and use of research
"in spring, we'll scale up another 500 acres." the general manager of xinjiang chang company, jobin, looks at the winter doo shui tree and says to the attendants. In january, the land was covered by snow and snow, and a row of tall duh trees was as young as the coming。
In 2016, under the guidance of professor su inquaon and dr. Chu, northwestern university of agroforestry and technology, the company contracted 200 acres of gobi wasteland in xinjiang. Today, these dobu trees have grown into forests with an annual income of over $3,000 per acre, improving not only the saline land but also providing employment opportunities for more than 20 villagers。
Doo-jin is a unique tree species in our country, where the bark, leaves and rubber can be extracted. Traditionally, latitudes 25 to 35 degrees north are the living zone of the dutsung, mainly cultivated in shaanxi, sichuan, hubei, hunan, guizhou and henan. A breakthrough across nine latitudes, bringing together three generations of west african farmers, pushed the duyas north to quetum, 44 degrees north latitude。

From seed selection to leaf forest cultivation
In the 1950s, clinical studies confirmed that tutong extracts had lasting safe pressure relief. Domestic and foreign demand was strong, and the crowd began cutting off trees from the wind, and by the 1970s and 1980s the resources of the wild duh trees were on the verge of depletion。
“we must not let this precious resource run out of our hands.” in 1982, zhang kang jian, a 43-year-old, was supported by a school to create a team to work on the problem of shortage of seeds and seedlings and to ensure the sustainable use of the resources of the commission。
Prof. Zhang kang jian led teachers and students in su inizuan, wang blue and mahihan, based in liuyang county, shanxi province, and guided by the content of the active ingredients, selected more than 50 high-quality seed resources from the main production areas of guizhou, sichuan, hunan and shaanxi across the country to conduct systematic reproduction and selection。
After 20 years of unremitting efforts, the team's selection of the “qin chang 1” tu changyan species was validated at the provincial level in 2003 to fill the gap in the country's high-drug-free and rubber-free varieties, opening up a river of good breeding for woody medicinal plants。
Since then, zhang kang jian's team has continued to work in the field of breeding and has produced the best species of qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin qin, in succession. The new national food raw materials certification of the dolphin oil products they have developed has also opened a new course for human consumption of the dolphin oil, giving a strong impetus to the high-quality development of our specialty oil industry。
As the state has increased its efforts to protect the country's resources, medicinal and glue extraction materials have shifted from bark to leaf. How to obtain more and better-quality leaves becomes a new topic for industrial development。
“the transformation of joe into a dwarfing of the development of the leaf forest is not simply a drying of the branches.” professor su inzumi, a cadre member of the team, continues with the topic. He described the fact that there were too few branches and that there was a marked lack of leaf production, and that too many branches led to a dichotomy of leaves, insufficient light and insufficient accumulation of active ingredients, which affected overall quality and production。
Through numerous comparative experiments, su inspense and the students and students of the subject group have finally established a system for the cultivation of the dutham forest: six branches are found on a dutham tree, each of them growing to a height of 3 to 4 metres, with the best quality and highest yield of the leaves, with an acre of duts usually producing 1. 5 tons of dry leaves。
This new pattern of cultivation has made it possible to move from “cutting a tree” to “covering a forest”. On this basis, the relevant experts within the united nations have promoted the inclusion of the duyat leaf in the national pharmacological code, opening new avenues for resource conservation and sustainable industrial development in the duyat。
The rapid and healthy development of the economy has been greatly facilitated by the expansion of the “qin changa” seed chain and the tujuna forest cultivation model throughout the country. Zhang kang-kian and su inzumi have done a great job. Zhang kang jian was recognized by the industry as “one of the founders of the tuzhin research in china” and su inzumi was awarded the lifetime achievement award by the association for oil and chemicals。
Resource mapping to functional development
With the increase in the scale of domestic cropping and the rise in social awareness of its high value in medicine and new materials, a new problem has emerged: how do you know how to "dry and drain" the duo in his body
“to be as good as you can be, you have to write from the bottom.” prof. Ko jin ming of the academy of chemistry and pharmacy took over the baton from his predecessors and led the team in cross-border exploration from 2000。
“the tungsten is a treasure for the extraction of chloro acid and acetone, and the tungsten bark is the preferred option for the acquisition of tungsten and specific sluices.” using techniques such as high-efficiency liquid chromatography, the team led the creation of fingerprinting maps of chemical components in different parts of the duchin and produced a concise resource map for the scientific development of duchin. The team also separated a special down-tripled ingredient from the duyat leaf, and for the first time revealed its mechanisms for containing neuroinflammation, providing a completely new scientific basis for the development of functional duyat foods and the prevention of neurodegenerative diseases such as alzheimer's disease。
"there's a way to pick them." the general manager of the embroidery agricultural company of luiyang county, takataka, spoke about the processing of the zhu jiahua flower, often preferring to sell a key. The doorway he talks about is the scientific work done by the team of prof. Quanta of the institute of life sciences in sinnon: the flowering and flowering periods are the best pick-up periods for tungsten flowers, during which the males achieve the best balance in the content and form of active ingredients, ensuring the quality and stability of raw materials。
The results of the study go far beyond that. The quanta team has confirmed the positive in vitro oxidation activity of male sugar and has laid the theoretical foundation for the development of health products. It has also combined tunya rubber with football-based, sulfuride/semmonized sea algae acids, developing uv-insisting, antibacterial and nanofilms and dressings, and expanding the prospects for tunya rubber applications in the field of agricultural protection and biomedicine。
“now, the development of tradition is so blindly inefficient.” high counterfeit is very impressive. His company had been engaged in the commissioning industry in luiyang county for 30 years and had been selling it at an early stage, mainly with a single structure. Under the theoretical guidance of scientific forces, such as the sinondu team, there has been a fundamental shift in the approach to the exploitation of companies, with a value of $18 million in 2023 and a sales revenue of $1. 262 million。
Thanks to the technical support of the team of experts from this generation of westinon, liuyang county has changed its old pattern of “sold one skin” and has shifted to the integrated development of the full-body sale of duya leaves, flowers, seeds and skins. At present, luiyang county, which is the country's largest county with 600,000 acres, has set up a special institute for industrial development in the country, which has introduced high-tech enterprises to apply new biokididostatic materials in areas such as aviation, medical appliances and so forth, extending to the entire industrial chain in the areas of tutang, medicine, food and fodder, with an annual value of over 120 million yuan。
From full-chain technology to china dream
“key breakthroughs were made in the field of green extraction and high-value applications.” in mid-november 2025, this news attracted public attention. This breakthrough was accomplished by the team of professor juno chu, whose core, the “rubber priority” step extraction technique, resulted in a reduction of energy consumption of about 24 per cent for the initial extraction of the dobu rubber and over 60 per cent for solvent consumption, while the resulting doogel purity met industry application standards。
“the preliminary selection has been a bottleneck in the rapid development of the economy.” as zhu has strongly described, natural rubber is an essential strategic commodity for national economic and defence security, and our natural rubber self-sufficiency is chronically low and heavily dependent on imports. Tung-gold is recognized as the second most promising source of rubber, and innovation to improve traditional extraction technologies is significant。
As a post-80 researcher, chu zhu zhiqiang has been working from 2009 to specialize in duchin research. After his stay in school, chu zhu zheng formally took over the baton of two generations of former generations, relying on the school's centre for the study of the doo-jung industry, to lead the team in the whole chain of technological innovation in the du-jung industry。
In addition to the breakthroughs in the initial selection technology, the chu-chang team constructed a three-stage biosynthesis model of tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu-tu。
“their results provide a solid technological basis for companies to take over the production of new material.” in a presentation by wang dawn, the head of shao-xio-ju china rubber company, many of the achievements of zhu zhu's team were found in the company, where the electromagnetic shield composites, prepared using tung-jam milk backfill techniques, showed excellent electromagnetic shielding and extremely low reflectivity in a given frequency band. This marked a critical leap from theory to industry in the application of the high value of tutong。
"the dutcomb industry is on the way." according to chu chu jian, the country is currently growing about 5 million acres, and by 2030 the plan is to build 50 million acres of high-impact farming industry, “an additional 5 million acres will be grown in xinjiang alone”。
In march 2025, the zhu chongqiang team, in conjunction with the beijing chemical university and others, reorganized the priority laboratory of the duzhun national forestry and grassland authority, and hired the best tuzhin research specialists in the country, such as duzhiji, zhao degang and fang qinghong, as core members of the laboratory academic council。
“the industrialization of the duo is a national relay of wisdom.” it is hoped that this focused laboratory will serve as a platform for the establishment of a national coalition of coordinated scientific research in the country, with full-chain technological coverage from seed excavation to the development of high-value products, promoting the adaptation of key technologies in different ecological areas and jointly writing a new chapter of china's duzhang dream.
