“at this spring, we will scale up another 500 acres.” the city of quetum in the xinjiang uyghur autonomous region in the winter, which is covered by snow, looks at a row of tall and tall duyam trees, and the general manager of xinjiang xinjiang corporation told the journalists。
In 2016, under the guidance of professor su inzumi and dr. Chu zhong of the north-west university of agroforestry and technology (hereinafter referred to as “sinano”), the company contracted 200 acres of gobi wasteland to try to plant a duyam tree that had never existed there. Today, they have grown into forests, earning more than $3,000 per acre per year, improving saline land and providing employment opportunities for local villagers。
As a unique economic tree in china, tutong bark, leaves and rubber can also be extracted. The traditional habitat is located at 25° to 35° n in shaanxi, sichuan, hubei, hunan, guizhou and henan, while planting it northwards to quitang, 44° n, has brought together three generations of western farmers and is a microcosm of their continued pursuit of dreams。
Sinondu's still chasing dream man
From seed selection to leaf forest cultivation
As a result of studies that have confirmed the lasting and safe depressive effect of the dotage on high blood pressure, domestic and foreign demand has flourished and, in the 1970s and 1980s, our wild dot trees were severely damaged under popular and wind-like cutting of trees, and their resources are on the verge of depletion。
“we must not let this precious resource run out of our hands.” in 1982, zhang kang jian, 43 years old, was supported by a school to create a research team to work on the problem of the shortage of doo-tree and seedlings. Based in luiyang county, shaanxi province, professor zhang kang jian led a team to select more than 50 high-quality seed resources from the main production areas of the country to conduct systematic reproduction and selection。
It is also male and female, with a long growth cycle and a high variety of good breeds found in the forest of the mountains. Zhang kang jian and the team teacher are thirsty for mountain springs, hungry for dry food, and in the wind and rain, they study sampling. Over the past 20 years, the selection of the qin gang 1 has filled the gap in the country's high-drug-free and rubber-free varieties and created a river of good breeding for woody medicinal plants。
This was followed by the selection of two, three and four species of qin qin qin qin qin, which formed the basis for the extensive expansion of the qin qin qin qin. They also developed a new national certification of new food raw materials, opening a new course for human consumption。
With the increased protection of the country's resources, “how to get more and better leaves” became 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 were clearly insufficient leaves, and that too many branches led to a lack of foliage, insufficient light and insufficient accumulation of active ingredients。
In the end, su inspense and the students and students of the group identified a pattern of dutham forest cultivation: six branches of a tree, each of which grew to three to four metres high, produced the best quality and highest yield of the leaves, with an acre of dutham usually producing 1. 5 tons of dry leaves. This new form of cultivation has made it possible to move from “cutting a tree” to “covering a forest”。
On the basis of a series of contributions, professor zhang kang jian was recognized by the industry as “one of the founders of the tuzhin research programme in china” and professor su inzheng received the “lifetime achievement award” from the association for oil and chemicals and the duzhin research alliance。
Resource mapping to functional development
How do you scientificly “dry and extract” the duo, who is full of treasures? “if you want to make the best of it, you have to write at the bottom.” following the baton in the hands of his predecessors, professor kenshin of the west agrochemistry and pharmacy school led a team to begin cross-border exploration in 2000 to decipher the dütther code as “green gold”。
“the tungsten blade is a treasure for the extraction of chloro acid and ketone, and the bark is the preferred option for the acquisition of tungsten and specific sluices.” using techniques such as high-efficiency liquid chromatography, the team created fingerprinting maps of chemical components in different parts of the duchan and prepared a simple “resource map” for the scientific development of dujung. The team also separated a special three-tripled ingredient from the duyat leaf and revealed for the first time its mechanisms to contain neuronitis, providing a new scientific basis for the development of functional duyat foods and the prevention of neurodegenerative diseases such as alzheimer's disease。
In the words of the general manager of luiyang agricultural company, "the doorway" refers to the scientific results of the team of prof. Tung zhouta of the faculty of life sciences of sinang: the flowering and flowering periods are the best pick-up periods for tungsten flowers, where the males achieve the best balance in the content and form of the active ingredient, ensuring the quality and stability of the raw materials. This “doorway” has become the “law” followed by the male industry in luiyang county。
In addition, the team of professor tung zhuang has studied and confirmed the good in vitro oxidation activity of male sugar, laying the theoretical foundation for the development of health-care products; the compounding of du rubber with football, sulfide/semblymide sea algae acid, etc., the development of uv barriers, antibacteria and nanofilms and dressings to heal wounds, and the expansion of the future of du rubber applications in agricultural protection and biomedicine。
For 30 years, the company in which he is based has been engaged in the trade-off industry, with the early years being dominated by the collection and sale of cash, a single industrial structure, and a fundamental shift in the company's approach to processing and utilization, under the guidance of a weston expert, with a value of $18 million in 2023 and a sales revenue of $1. 262 million。
Thanks to the support of a team of experts, the county of luiyang left behind the former “sold one skin” model, which shifted to the integrated development of the “solding of all body parts” of the duya leaves, flowers, seeds and skin. At present, the first county in the country to grow 600,000 acres of heavy land in luoyang has established the institute for industrial development of the dutsung region, which has introduced high-tech enterprises for the application of new biokiddoo materials in areas such as aviation, medical equipment, etc., and has developed an industry-wide chain covering the areas of tutang, medicine, food and feed, with an annual value of more than 120 million yuan。
From full-chain technology to china dream
In november 2025, a groundbreaking study was completed by the team of professor juno chu, whose core “rubber priority” step extraction technology reduced primary extraction energy consumption by about 24 per cent, solvent consumption by more than 60 per cent, and the purity of the sumo glue received met industry standards。
In august 2019, professor chu's first-hand team took samples at xinjiang station
“the preliminary selection of tutong has been a bottleneck for rapid industrial development.” as zhu has strongly described, natural rubber is a key strategic commodity essential to national economic and defence security, and our natural rubber has long been dependent on imports, with the second largest potential source of rubber in the country. As a post-85 researcher, chu chu chu jian has been specializing in the study of the duzhun since 2009. He took on the baton from two generations of seniors, and led the team on the whole chain of technological innovation in the dutting industries, with the support of the school centre for the study of the duts。
The team developed a three-stage biosynthesis model for tutong, which supports the scalding of the dutham forest in the north-west dry zone; developed a first nationwide set of dotang machinery to achieve an efficient and non-destructive sowing of dotang and an efficient separation of dotang, skin and wood; and promoted dotang as a state-sanctioned drug congener。
"the dutcomb industry is on the way." chu chu jian stated that the country was currently growing about 5 million acres, and that by 2030 the plan was to build 50 million acres of high-impact farming industry. In march 2025, the chu chong team joined forces with the beijing chemical university, among others, to reorganize the priority laboratory of the duzhun national forestry and grassland authority and to hire a number of outstanding experts as core members of the laboratory academic council。
“the industrialization of the duo is a national relay of wisdom.” it is zhu's hope that this focused laboratory will be used as a platform for the establishment of a national coalition of coordinated scientific and scientific institutions in order to achieve full-chain technological coverage from seed mining to the development of high-value products and to promote the adaptation of key technologies in different ecological areas。
