Doo is a treasure. In addition to its medicinal and edible value, the dubes drawn from the leaves, skins and roots of the duyat trees are not afraid of the corrosive, non-variable, waterproof, anti-sorption, radiationproof. Adding 3 to 5 per cent of tungsten can increase the resistance of tyres and prolong their useful life. More magically, if it is punctured, the temperature above 80 degrees celsius can heal itself for some time。

Tu is a plant that is unique to our country, and more than 95 per cent of the world's tujun resources are in china。
Organisms of plant tissues such as tradables, leaves, flowers and seeds contain a variety of important components that can be exploited. They are a tree species that combine rubber, resin, wood cellulose, grease, protein, and pharmaceutical activity components with higher potential economic benefits。
As the times evolved, more and more people were recognizing the efficacy of the duo, which was even referred to as the “vegetative gold” “china rubber tree”。

Doo is a treasure
If you break the bark, branch or leaf of doo-jung, you'll see a silk bond, like a thread, so it's also called a folk twirl. Those adhesive threads are tutong's glue, high insulation, and natural rubber are the same isomers and are the world's second largest natural rubber resource, the same as the natural rubber chemical components produced in tri-leaf rubber trees。
Zhang kang jian, a professor at the north-west university of agroforestry and technology, was one of the first scientists in the country to do research on the truth. Under his leadership and that of professor su inizun, the sinon doo team, after more than 30 years, created a number of “zero breakthroughs” in the history of the truth: the conversion of dou chaolin to a dwarf plant, the realization of the proceeds of the same year's cultivation, and the production of the first series of high-gel, high-drug-type “tin chen 1-4” new varieties, and the publication of the first comprehensive system at home and abroad on the production of metabolites and sunsee oil, china-china-specific plant fat - sowing oil, and the production of the country's first qinite and live charcoal in the desert, and so on。
In 2009, chu zhu zhiqiang, a graduate student at the northwestern university of agroforest technology, followed by professor su inizheng in his study and continued his research from professor sun junkura, professor seri and professor koo hsiung kobayashi of japan, and went all the way from a master's degree to a doctorate, and participated in the international cooperation project “trutex genetic research” “technology research for the production of tutang”, which led the team for the high-value utilization of the resources of tutong on the 110th anniversary of the birth of deng xiaoping, in august 2014, in the people's hall。

Resourceization of the treasure tree
What does rubber do
Our country is the world's largest rubber consumer, but its main raw material is tropical, narrow in its living areas and can be cultivated only in areas such as hainan island and the western twina. According to incomplete statistics, our natural rubber production in 2022 amounted to 8. 18 million tons, with a surface demand of 343. 03 million tons and a dependency on imports exceeding 75 per cent for more than 10 consecutive years。
The hope of breaking the bottleneck of low self-sufficiency in our natural rubber resources is pinned on the duplex, but the backward technology of extraction and refining of the duplex rubber is one of the key constraints on our capacity to produce the duplex rubber。
“traditional chemical extraction methods are costly, inefficient, purified and solvents pollute the environment. There are also defects in bio-geling, such as poor fermentation conditions and poor fermentation-based glues. Dr. Zhu zheng stayed after graduation and began to focus on the pureness of doo qi。
Perseverance and success。
In recent days, zhu zhu's team has made a new breakthrough in research into the development of the tutong function, increasing the purity of the duttang extraction to more than 99. 0 per cent, and overcoming the scientific challenge of “efficient extraction and purification of tuttang”。
For the first time, chu has led a team consisting mainly of young teachers and graduate students, proposing a new method for clean extraction of tungsten by low-green comelting organisms — the lactated-cyanide zinc solvent system. The new method has increased significantly in its efficiency, with production and purity exceeding 91. 0 per cent and 99. 0 per cent, respectively, compared to traditional extraction methods such as mechanical shredding and alkalin treatment。
The cost of extraction and separation of tuctong has been significantly reduced, but the lack of supply of raw materials has been compounded. It is encouraging to note that the national plan for the development of the dutch industries (2016-2030), which was launched by the former national forestry administration in december 2016, clearly states that 3 million hectares will be cultivated by the country by 2030, which provides a follow-up to the development of the entire economy。
“if 3 million hectares of industrial base were to be developed, the country's annual production of tungsten rubber would exceed 1. 2 million tons, which is one or two times the current production of natural rubber in the country, and would achieve 60 per cent of the demand.” chu jian。

The duality of the rubber-plastics, which is unique to the du, has made its application in the areas of functional and engineering materials such as thermoplasticity, thermal elasticity and high elasticity increasingly visible, with the national economy and f-fdtl workers placing an urgent demand on the dut in terms of production, quality, performance, etc。
Can you make this tree worth more? Could it be more efficient? New problems in industrial development have emerged again。
Based on the clean and efficient extraction upstream, the research team used molecular dynamics to predict the compatibility of tungsten with butler rubber and natural rubber. The results showed that, when the amount of tungsten is less than 50 per cent, tungsten and tungsten rubber have good coming properties at 398 kc and tungsten and natural rubber at 350 kc. As a result, the team proposed a co-sulfide process for tungsten compound butyl or natural rubber. The studies found that the compressor from the co-sulfurization process had better anti-aging, resistant, grinding and hydrophobic properties than traditional rubber products。
Using the superior properties of tuttex, chu has led the team in a combination of self-confirmation technology systems, using magnetic fillings — empty microballs in manganese zinc iron oxygen and conductive fillings — superconductive carbon black, developed through thermal pressure-formation process, a tuttol-based green, efficient electromagnetic screen film that combines grindability, hydrophobic and corrosive properties, with greater than 80 db shield efficiency. The team revealed the electromagnetic interference shielding mechanism of the material, which was dominated by the medium loss and coordinated with the magnetic loss, by such means as re-magnetic conductivity, re-transmittance constants and electromagnetic interference shield efficiency calculations。
The results of the above-mentioned study provide technical support for the clean and efficient scale extraction separation of tungsten and theoretical support for the development of multifunctional electromagnetic interference shield products in new applications such as new energy vehicles, radar signal shielding and flexible wearable equipment, using tungsten as a polymer matrix。

Yelling and golling are the most promising industrial integrated utilization models in the current dugland. “for an acre, two to three people work 10 hours in a row to complete a flat mission, and another day to collect leaves, while it takes 10 people 20 days to skin the trees.” according to chu, traditional methods of artificial harvesting are inefficient and costly and make it difficult to meet the demand for raw materials for the rapid development of the economy。
For the first time, zhu zhu has led the team in the development of planters, flattening and defoliation equipment for the yeltsin cultivation model. Using the flat and defoliating machines, 5-8 acres of the dochinin are collected daily. On the doo-fin harvest, the zhu zhu team developed a hammer-forming doo-goe-shell peeler, with only 1. 78 per cent loss of new equipment to seeds and more than 90 per cent impurity, resulting in the efficient separation of fin-sized machinery and nuts and shells。
The spring of industrial development began with the advancement of mechanized harvesting equipment and technology.

Currently, the chu chong team has proposed a “order-based forestry” model for the entire period from planting to harvesting, promoting 60,000 acres of the doung production base in shaanxi, xinjiang, henan and shandong, with farmers earning up to $2 million a year。
