The industrial status of Eucommia ulmoides gum, the application of Eucommia ulmoides gum

In terms of resource cultivation, the Chinese Academy of Forestry took the lead in selecting and breeding 6 high-yield varieties of Eucommia ulmoides, and using orchard cultivation technology to produce fruits from Eucommia ulmoides.

The amount is 40 times higher than the traditional cultivation mode, and the rubber yield per hectare reaches 400 kg; In terms of industrialization research, it has formed a complete property rights system of Eucommia ulmoides with independent intellectual property rights and leading the world, and basically has the foundation for industrialization.

At the same time, China's eucommia industry also has market advantages. It is estimated that the fruit yield of Eucommia ulmoides is achieved by using high-yield rubber varieties and orchard cultivation technology.

It is 40 60 times higher than the traditional cultivation mode, and the rubber yield per hectare is 400 600 kg. If the planting area of Eucommia ulmoides is expanded to 3 million hectares, the annual output of Eucommia ulmoides rubber can reach more than 1.2 million tons, which can fundamentally alleviate the problem of lack of natural rubber resources in China.

Eucommia ulmoides gum has always been the most important development and support industry, such as the 2011 national adjustment project guide to "natural rubber eucommia planting and production" cultivation included in the scope of agricultural industry support. On December 26, 2014, the General Office of the People's Republic of China issued the "Opinions on Accelerating the Development of the Woody Oil Industry", which clearly included Eucommia ulmoides in the key woody oil tree species to support the development. In 2012, under the leadership of the --- Social Development Research Center of the Chinese Academy of Social Sciences and the --- Economic Forestry Research Center of the Chinese Academy of Forestry, Henan Hengruiyuan Industrial Co., Ltd. was established in cooperation with the people of Ruzhou City, with a total industrial park area of 450 acres, of which 250 acres are "National Agricultural Achievement Transformation Fund Demonstration Base".

Eucommia ulmoides has a variety of industrial products, relying on Eucommia ulmoides not only to produce natural Eucommia ulmoides gum, but also to produce Eucommia ulmoides oil, chlorogenic acid, Eucommia ulmoides capsules, Eucommia ulmoides male flower tea, organic fertilizer, activated carbon and other products. The diversification of Eucommia ulmoides products can not only bring considerable benefits to the majority of planting enterprises, but also reduce market risks, and is an industry with good prospects at present.

1. Eucommia ulmoides gum can be used to develop thermoplastic functional materials and thermoelastic shape memory materials. It can be used in the development of tires in aviation and related industries, and can solve a series of major problems such as tire strength, tire life, tire friction and heat release that have plagued the aviation industry and related industries for a long time.

2. Based on the unique structure and properties of Eucommia ulmoides gum, low-temperature plasticity materials and thermoelastic materials can be developed, which are widely used in various fields of the national economy such as rubber industry, chemical industry, medical treatment, and sports.

3. Eucommia ulmoides has good insulation, water, acid and alkali resistance, and corrosion. It can be used for underwater wires or submarine cables, or directly manufacture electrical insulation equipment, acid or alkali resistant linings, etc.

Eucommia ulmoides rubber has good insulation, water resistance, acid and alkali corrosion resistance. For a long time, it has been used for underwater wires or submarine cables, or directly manufactured electrical insulation equipment, acid- or alkali-resistant linings, etc.; It can also be used to make tires; It is also widely used in foreign countries and used in medical fields such as dentistry with the advantages of non-exclusivity in the body.

Eucommia ulmoides is a unique and valuable economic tree species in China, and it is also an important collagen plant with the most extensive application in the world. The leaves, bark and peel of Eucommia ulmoides are rich in a white filamentous substance called Eucommia ulmoides gum. The discovery of the unique "rubber-plastic duality" of Eucommia ulmoides gum has opened up the application field of Eucommia ulmoides gum.

Its comprehensive development and utilization has aroused extensive attention from relevant state departments.

The seedlings of the Eucommia ulmoides tree can be used to extract rubber, and the age of the tree increases to 10 to 15 years, and it can produce more than 270 kg of rubber per hectare. The gum content of Eucommia ulmoides tree is: 11% 20% of dry bark; Kernel and dried fruit with 12% gum content; Dry leaves have a gum content of 4% to 6%; The gum content of the dried bark of old twigs is 10%.

Eucommia gum is one of the natural rubbers, produced from the Eucommia ulmoides tree, which belongs to the family Eucommiaceae, and is a specialty of China. In addition to woodiness, the leaves, roots, bark, and seeds of the Eucommia ulmoides tree contain Eucommia gum.

China's largest Eucommia ulmoides base is located in Luoyang County, in the Qinling Mountains, with a total of 100 million trees and 580,000 acres of high-quality eucommia resources. The unique natural environment of the Great Qinling Mountains provides a good breeding ground for the growth of this rare and ancient tree.

Luoyang County Jiamu Eucommia ulmoides industry **** is a collection of Eucommia ulmoides technology research and development. Product development. The agricultural industrialization science and technology demonstration enterprise integrating market development and base construction is the Ministry of Science and Technology of the People's Republic of China.

The Ministry of Finance focuses on supporting enterprises in technological innovation. It is also the owner of the technology that fills a number of technical gaps and the development technology of Eucommia ulmoides, and is the backbone and leading enterprise in this field in China.

Cili County, Zhangjiajie has nearly 20,000 acres of eucommia forests, which is a large-scale eucommia forest farm built under the guidance of Soviet experts in the early days of liberation, and is also one of the world's famous eucommia forest farms, known as the "hometown of eucommia".

Eucommia ulmoides is a unique plant in China, and more than 95% of the world's eucommia resources are in China. Eucommia ulmoides is also a high-quality gum source tree with the widest range of adaptation and the greatest development potential in the world. The fruits, leaves, bark and roots of Eucommia ulmoides are rich in Eucommia ulmoides gum, and based on the unique structure and properties of Eucommia ulmoides gum, three types of materials with different uses can be developed:

Rubber high-elastic materials, low-temperature plasticity materials and thermoelastic materials are widely used in the rubber industry, aerospace, national defense, shipbuilding, chemical industry, medical treatment, sports and other fields of the country's early ethnic rough economy, with a wide range of industrial coverage.

First, as a renewable natural rubber resource, it can reduce import dependence and help ensure the supply of domestic rubber resources and the sustainable development of the rubber industry.

Second, Eucommia ulmoides rubber can help the development of rubber products such as high-performance tires and enhance the added value of products.

Third, Eucommia ulmoides gum is the core driving force for the development of Eucommia ulmoides industry.
