Hemp Researcher Zhang Jianchun: Chinese Ink On Hemp

Zhang Jianchun direction

Honorary president Du Yuzhou introduced wooden ceramic bulletproof materials made from hemp core powder.

While carrying out the research on hemp cultivation, the Military Research Institute of hemp materials and relevant research institutes in China have made a lot of hard and detailed exploration of many technical researches on hemp processing.

The past and present of hemp

In ancient times, when we were still in the matriarchal society, we would not think that after the use of hemp fiber for "Ge bu", thousands of years later, hemp can be made into fashionable clothes and all kinds of ornaments. Hemp stems can be made into man-made fibers and wood plastic construction products. Hemp seeds can be processed into health care oil and nutritious food. The leaves and flowers of linen can be made into cosmetics and medicines, and the roots of the hemp can be used as activated carbon and woodceramics, and their descendants can be used so incisively and vividly.

Ma is one of the earliest textile fiber materials used by mankind. It once had the reputation of "the source of the national textile, the clothing of all ages".

Archaeological data show that the earliest domestication and cultivation of hemp in China were about 5000~6000 years ago.

Ma Zeng was an important source of fiber and food for human needs in history. Not only in China but also in the world, it was widely used in ropes, canvas, textile and clothing, paper, food and oil, and made an indelible contribution to navigation, military, economic and social development.

Hemp is a vigorous plant. It is a large family from plant taxonomy. It is mainly divided into three categories: fiber, linen, medicinal hemp and wild hemp.

China is the first cultivated and used in the world.

Countries, different regions have different names for hemp. Northeast is called linen, Shandong is called hemp, Anhui is called hemp, Gansu is called hemp, and Yunnan is called hemp.

With the extensive planting of cotton and the development of cotton processing technology, the emergence and development of synthetic fiber and petrochemical technology, wood pulp and paper technology, and the emergence of various new packaging materials have gradually reduced the planting and utilization of linen.

Coupled with the misunderstanding of the drug problem in the 60s of last century and people's understanding of the toxicity of the crop, cannabis was listed as a prohibited crop in many countries, and all kinds of linen products were gradually fading out of the mainstream textiles.

In recent years, with the development of science and technology and the recognition of hemp, internationally, low toxic or non-toxic varieties of THC (four HNP) content less than 0.3% have been allowed to be called industrial hemp. At present, 29 countries in the world grow industrial hemp.

In China, "Yun Ma 1", which was studied and improved by Yunnan Academy of Agricultural Sciences,

None of them has the characteristics of refining drugs, which belongs to the non-toxic varieties recorded by the Ministry of public security.

The formal connection between Zhang Jianchun and hemp research dates back to 2003, when he served as chief engineer of the Quartermaster Equipment Research Institute of the PLA General Logistics Department.

The close contact with Han Ma led to his interest in research and practice as early as young. There were always some chance coincidences in the dark. The name of Zhang Jianchun, a boy who had used the old spinning hammer to make the thread, was written in history with hemp.

After the establishment of the military hemp research center of the general Quartermaster Equipment Research Institute, Zhang Jianchun gave a brand-new name to Chinese industrial hemp (CHINA-HEMP) based on literature and homophonic English hemp.

"The birthplace of hemp in China is a native Chinese species of hemp, so the meaning of it is created in China and China."

The short explanation contains Zhang Jianchun's deep affection for his motherland.

It is also a deep sense of naming, which laid a good foundation for the later research, industrial development and going abroad, and Zhang Jianchun became the initiator of hemp.

In the 90s of last century, the problems brought about by the development of modern industry at the expense of resource consumption and environmental problems were highlighted. The sustainable development of society and the rational utilization of resources were widely concerned in the world.

China is a large agricultural country. Land resources, fiber resources, timber resources and petroleum resources are in short supply. The problem of agriculture, rural areas and farmers is prominent. Under such an international and domestic environment, vigorously developing hemp industry has special scientific, economic and social significance.

In 2005, the General Logistics Department issued a scientific research plan for the application research of "natural phloem fiber in military equipment and clothing" to the hemp project team.

In 2006, the General Logistics Department issued "

The army logistics research plan on Applied Research of logistics equipment.
