摘　　要：探讨近几年新疆长绒棉的发展概况及质量变化。以新疆阿克苏地区长绒棉为例,对2017年至2020年长绒棉质量指标统计追踪,根据GB/T 19635—2005《棉花长绒棉》标准,分析了4年来长绒棉质量的变化趋势。结果表明:2017年至2020年,长绒棉标准长度级36 mm及以上棉花占比均在74.82%以上;长度整齐度及断裂比强度指标优异;马克隆值在A级和B2级占比均在98%以上;长绒棉品级2级比例逐年增大,而1级比例逐年减小。认为:2017年至2020年新疆长绒棉品级有所下降,其他质量指标稳定且优异;应从改善种植条件、推广优良品种、优化采收及加工质量等方面稳定和提高新疆长绒棉质量。Development overview and quality change of Xinjiang long-staple cotton in recent years were discussed.Long-staple cotton in Xinjiang Aksu area was taken as an example,long-staple cotton quality indicators from 2017 to 2020 were tracked statistically,according to GB/T 19635—2005 Cotton-Sea island cotton standard,changing trend of long-staple cotton quality in the past four years was analyzed.The results showed that:from 2017to 2020,proportion of long-staple cotton with standard length of 36 mm and above was more than 74.82%.Length uniformity and breaking specific tenacity were excellent both A grade and B2 grade,micronaire value were more than98%.Proportion of long-staple cotton 2 grade was increased year by year,while proportion of long-staple cotton 1grade was decreased year by year.It is considered that the grade of Xinjiang long-staple cotton is decreased from 2017to 2020,while other quality indicators are stable and excellent.Quality of Xinjiang long-staple cotton should be stabilized and improved from the aspects of improving planting condition,promoting better variety,optimizing harvesting and processing quality.
