Before the Song Dynasty, China only had the word "cotton" beside the silk, but there was no word "cotton" beside the wood. The word "cotton" began to appear in Song Shu. It can be seen that cotton was introduced in the Northern and Southern Dynasties at the latest, but it was mostly planted in the frontier. At the end of Song Dynasty and the beginning of Yuan Dynasty, a large amount of cotton was introduced into the mainland.
The record about the introduction of cotton into China is as follows: "China was first planted between the Song and Yuan Dynasties and benefited from Guanshan and Min Guang. Built abroad, Guang Guang is connected with seagoing ships, so Guanshan is connected with the western regions. "
From then on, we can know that cotton was introduced by land and sea. Cotton in Quanzhou was introduced from the sea and soon spread to the south. As for the nationwide promotion of cotton, it was delayed until the early Ming Dynasty, and it was not until the "Emperor Zhu" that it was promoted.
China cotton producing area:
Jianghuai Plain, Jianghan Plain, South Xinjiang Cotton Region, South-central Hebei, Northwest Shandong, North Henan Plain, and Coastal Plain in the Lower Yangtze River.
