在宋末元初以前,我国中部诸省均以丝麻为衣被原料,尚未植棉,但对外族、外国所用棉织品却很注意,少数皇亲贵族已有使用进贡棉织品的,并对棉布给以很高估价,认为棉布的特点是“丽密轻煖”,不逊于茧纊。所以当时的学者都已很注意描述棉花的植物学特征与生物学特性。 Before the end of the Song Dynasty and the beginning of the Yuan dynasty, all the central provinces of China used silk and linen as raw materials for clothing and clothing, but they did not yet plant cotton. However, they paid great attention to foreign and foreign cotton fabrics, and a few royal and aristocratic families had used cotton fabrics for tribute, With a high valuation, that cotton is characterized by “Li Mi light warm,” no less cocoon 纩. Therefore, scholars at that time paid great attention to describing the botanical characteristics and biological characteristics of cotton.
