摘　　要：研究了不同生长期对苎麻纤维化学成分的影响。分析发现,提前收剥,脂蜡质、水溶物、果胶质、半纤维素均上升,但木质素下降,总含胶量受收剥期影响不是很明显。二麻提前25天收剥则纤维支数由传统时期收剥的1195支提高到2059支,纤维品质明显提高,且减轻苎麻脱胶的负担,缓解了苎麻的刺痒感。The effect of different harvesting dates on the chemical composition of raw ramie fiber was probed. It was found that the wax,water-solubles,pectin,hemicellulose content would increase and the lignin content would decrease before harvest dates,but no obvious difference for total gum observed.Harvesting 25days ahead of tranditional harvest date for second harvest would upgrade the fiber fineness from 1195 to 2059,better the fiber quality,alleviate the burden of degumning and also relieve the sense of itching.
