Is ramie native to China?

Scholars all over the world believe that ramie originated in China. Vavilov (195 1) and R.H.Kirby( 1975) clearly pointed out that ramie originated in the central and western regions of China, and this research result was recognized by scholars. There are many varieties and types of ramie in China, with a vast planting area and a long history of cultivation, processing and utilization, which provides a basis for studying the origin and evolution. Unearthed cultural relics: Ramie rope was unearthed in 1975, a Neolithic cultural site 6000 years ago in Hemudu, Yuyao County, Zhejiang Province. From 65438 to 0958, three ramie fabrics with distinct warp and weft were unearthed at the Neolithic cultural site in Qianshanyang, Xing Wu County, Zhejiang Province, more than 4,700 years ago. 1980 Two pieces of ramie calico unearthed from Cliff Tomb in Guixi County, Jiangxi Province are the earliest double-sided ramie calico found in unearthed cultural relics in China, with a history of more than 2,700 years. 1972 The fine ramie cloth unearthed in Changsha, Hunan Province, has a history of more than 2,000 years, and its fineness is no less than that of poplin today, with a warp and weft density of 32 ~ 38× 36 ~ 54 /cm2. The excavated cultural relics are enough to prove that the utilization of ramie in ancient China has a long history, and the technical level of ramie spinning has been continuously improved and improved. The descriptions of ramie in ancient books are as follows: "The East Gate Pool can be covered with ramie" in The Book of Songs Martin in the 6th century BC, and "Ramie is covered with ramie" (the bridle of morning glory) in The Book of Rites. In the Zhou Dynasty, a "Dian" official was set up, specializing in the production and collection of ramie, cocoon and other textiles, so "Zhou Li Tianguan Zhong Xia" recorded the "Dian" brown cloth, silk and silk, which was a fine ramie fabric. Ramie in China has been growing from north to south from wild fiber collection to cultivation, and has been gradually introduced to foreign countries from domestic cultivation. This process has experienced five or six thousand years of historical evolution. According to Zheng Zitong (1604), wild ramie is also called hemp and wild ramie. With the increase of demand, this inexhaustible wild ramie gradually felt inadequate, so ramie planting began. Artificial cultivation began in Shang and Zhou Dynasties. Ramie has been widely planted in the Yellow River Basin since Qin and Han Dynasties. For example, it is recorded in Geography of Hanshu that ramie is planted more in Henan and Shaanxi, and less in the Yangtze River basin than in the north. In the 3rd century AD, Luji recorded that ramie was expanded to "three harvests a year from Jingyang to Shenyang" in Cao Sen, Shi Mao, and there were few birds, animals, insects and fish. In 488 AD, the Book of Songs of the Northern and Southern Dynasties recorded: "All counties and counties use their capital to persuade them to grow sericulture and hemp and do their best." The planting area of ramie in various provinces in the south of the Yangtze River is constantly expanding. During the Sui and Tang Dynasties, ramie production developed further. Most of the five roads and twenty-nine Kyushu recorded in the New Tang Book are in the south of the Yangtze River, and the cultivation areas are in Fujian and Zhejiang provinces in the east, guangzhou fu in Lingnan in the south and Sichuan Province in the west. Since the Yuan Dynasty, compared with sericulture, the cotton in the Central Plains can be harvested easily. It can be said that the ramie area in the Yellow River basin is decreasing year by year, and the wind of cotton planting is very strong. There are more ancient books about ramie cultivation techniques, including growth and climate, land selection and soil preparation, crop rotation and continuous cropping, seed selection and propagation, fertilization and management, pest control, harvesting and processing. With the continuous development of ramie cultivation technology, textile processing has been greatly improved and improved. From the calendering of ramie textiles in the Han Dynasty to the fabric varieties gradually formed in various places after the Song and Yuan Dynasties, including the famous "wrinkled cloth" in Zhuji, Zhejiang, "bamboo cloth" in Guilin, "cloth" and "false yarn" interwoven with ramie and cotton yarn in Yongzhou, and "summer cloth" in Hunan and Jiangxi provinces. Therefore, the cultivation, planting, production and processing of ramie have attracted more and more attention in the world. 1733 was originally introduced to the Netherlands as an ornamental plant. In 1737, plant taxonomist Linnai obtained ramie plant specimens from China and described their botanical characteristics. 1844, the French warship Victory was brought back from China and introduced to France. 185 1 year, British corning enjoyed a trip to China, brought the seeds to Britain, and then introduced them to the United States in 1857, and then introduced them to Brazil and Colombia from the United States. Ramie was planted earlier in Korea and Japan, which has a history of more than 600 years and was also introduced from China. As can be seen from the above, ramie all over the world is directly or indirectly introduced and cultivated in China, so outsiders call it "China Grass" or "Nanjing Hemp".
