Turn on the power and let the kenaf decorticator whistle and turn, and put a bundle of ramie with leaves into it. After a few seconds, it is already green hemp fiber. This is what the reporter saw today at the Institute of the Chinese Academy of Agricultural Sciences. More than 80 experts from the country engaged in the research and promotion of hemp machinery gathered in Changsha and called for the state to provide relevant policy support and regulations in the research, promotion and standard setting of hemp machinery to change the harvest of China’s hemp crops. The situation dominated by hand.
Hemp is one of the world’s four major natural fibers. China’s hemp resources are extremely rich and have become the world’s hemp textile power. However, for a long time, the harvest of China’s hemp crops is mainly manual labor, labor intensity, high operating costs, low production efficiency, and the occupation of the entire production process accounts for more than 60%. “Harvesting difficulties” has become a bottleneck restricting the development of the hemp industry.
For the high-efficiency economic crops unique to China, such as ramie, after more than 50 years of efforts, more than 30 types of kenaf decorticators have been successfully developed in China, but there are less than 10 kinds of products that are widely used in production. How to change this situation?
According to expert analysis, in addition to speeding up technological advancement in kenaf decorticators, the state should also provide relevant policy support in the research and promotion of hemp machinery, and accelerate the formulation of industry and national standards.
