Eucommia ulmoides is a unique nourishing and precious medicinal material in China. It has the reputation of “Chinese god tree”. It has been planted in Xiangyang for thousands of years, mainly in mountainous areas such as Nanbao Valley. It is all treasures, and leaves, flowers, fruits and skins are all Chinese herbal medicines.

Eucommia ulmoides are all treasures, and leaves, flowers, fruits and skins are all Chinese herbal medicines. Flowers and leaves can be used to make tea, and the leaves can be used to extract chlorogenic acid and tea powder. However, the growth rate of Eucommia ulmoides is very slow. Before and after the Qingming period, the flowering period is only 7 days. The harvesting must be carried out manually. A skilled worker can only pick about 40 kg a day, and 10 kg of flowers can make one kilogram of flower tea. Eucommia ulmoides (seed) is rich in linolenic acid oil, which has a good lipid-lowering effect. The price per kilogram is as high as two or three hundred yuan. It is the raw material for health care products and has been listed as a new resource food by the Ministry of Health. Eucommia ulmoides is called “Chinese rubber tree”. It takes off a leaf and puts it in the hand. The leaf surface will be damaged into hundreds of small pieces. There are many filaments connected between the small pieces. These filaments are gutta percha. The raw materials of gutta percha mainly include fruits and leaves, and the yield of the fruit is low but the amount of gum is high. Eucommia gum can be used in aviation, construction, industry, medical and other fields. The biggest role is to mix with ordinary rubber to improve the wear resistance and tear resistance of rubber. Taking automobile tires as an example, if a tire produced by ordinary rubber can travel 100 kilometers, a car tire with gutta-percha can be driven for 500 kilometers. On November 30, 2013, the 11th China Agricultural Fair and the 10th Wuhan Agricultural Fair opened. Fuyang City held a new product promotion conference for the Eucommia Industry Center at the Wuhan International Expo Center Conference Center, and used the Agricultural Fair to showcase the new products of Eucommia Features. For a long time, Fuyang City has encouraged the use of the traditional production advantages of Eucommia ulmoides and actively supported the Eucommia industry to become bigger and stronger. The Eucommia plantation, Ru0026D and processing enterprises represented by Duzhong Technology Industrial Co., Ltd. have risen rapidly. At present, the planting area of ​​the company's Eucommia is 620,000 mu, and the eucommia tree is more than 60 million. The annual output of Eucommia ulmoides is 25,000 tons, the male flower is more than 300 tons, and the fruit is more than 500 tons. At the promotion meeting, relevant experts from the Institute of Chemistry of the Chinese Academy of Sciences, the China Rubber Industry Association and the Cultural Research Center of the Chinese Academy of Social Sciences read out the new product identification report of Fuyang Eucommia, introduced the development status of the national Eucommia industry, and provided suggestions for the development of the Duzhong industry in Fuyang. . Experts believe that while developing traditional Eucommia cultivation, Fuyang has invested a lot of manpower and material resources in processing technology and product research and development, developed intensive processing, and seized the development highland. The Eucommia industry has entered the era of large-scale and intensive processing. The rapid growth of the Eucommia industry has opened up a new path for the development of the Shenyang Linte industry, adding new vitality to the development of the characteristic agricultural product processing industry. I hope that the Eucommia products of Fuyang will go out of Fuyang and go out of Hubei to go international.
