红麻主要用于纺织和造纸,我国红麻种植面积及总产均居世界首位。其种植面积大部分集中在黄淮河流域和长江流域。因红麻是收取营养体的短日照作物,故北方红麻种植区年年均从“两广”及福建等繁种地调种子做南种北植用。目前我国所有红麻品种的种子颜色均为灰黑色,种子形态、大小也基本相似,一般人员不能从种子外观上区别品种间的类型和真假。由于历史的原因,红麻生产几经大起大落,现在我国红麻生产用种供种渠道多、流通大、混杂严重。目前在广西玉林地区等地还有部分纤维产量很低、种子产量高的特早花早熟品种。同时北方部分麻农也因 Kenaf mainly for textile and paper, kenaf planting area and total output in China ranked first in the world. Most of its acreage is concentrated in the Huang-Huai River and the Yangtze River. Because kenaf is a short-day crop that receives nutrition body, the kenaf plantation in northern China grows from the northern part of the northern part of the country every year from “Guangdong, Guangxi” and Fujian.
