摘要: 采用地理信息系统为信息处理技术方法,以黄河流域棉区、长江流域棉区、西北内陆棉区的早熟、中熟和早中熟类型的杂交棉和 常规棉品种为试验材料,通过 2005—2014 年国家级棉花品种区域试验对棉纤维 4 个主要纤维品质性状(长度、马克隆值、比强度和纺纱 均匀性指数)进行地域性分析研究。 结果表明,中熟棉品种纤维长度达到纺中高档纱所需长度标准要求;黄河流域的河北北部中熟品种 近几年纤维长度下降,长江流域的长江中下游地区纤维长度表现较好;中熟品种的纤维比强度分布大致呈自西向东、由北向南增加的趋 势。 三大棉区不同熟性类型马克隆值有明显差异。 此外,黄河流域棉区的华北平原一带是适宜种植推广中长绒、高比强和高马克隆值 的长强粗纤维的常规棉品种的区域,黄河流域棉区的黄土高原一带是适宜种植推广普通高产型的短弱粗纤维的常规棉品种的区域。 长 江流域中下游棉区是适宜种植推广中长绒、高比强和高马克隆值的长强粗纤维的杂交棉品种区域。 而西北内陆棉区的东疆地区是适合 推广种植长强细的优质常规棉品种或长绒棉品种的区域,可以作为我国棉纺工业纺髙支纱的重要优质棉生产基地。 总之,西北内陆棉 区常规棉仍然是我国棉花品质性状表现最具发展潜力的品种类型。
