通过对黄河流域棉花品种区域试验中纤维品质结果分析，发现黄河流域棉纤维品质区域性分布有明显差异。纤维长度长短分布走向大体为：淮北平原亚区、华北平原亚区沿海地区华北平原亚区中心地带黄土高原亚区。比强度高值区为华北平原亚区中部和黄土高原亚区东部，低值区出现在淮北平原亚区大部和黄土高原亚区西南部。麦克隆值在本流域有沿东南西北方向降低的趋势。综合纤维品质以环缕纱强为例，高值区为河北大部，山东中西部和江苏北部地区；低值区有两部分：一是豫东南、鲁西南和皖北地区，其主要原因是纤维较粗、比强度偏低，二是黄土高原亚区的三原、临汾一带，其主要原因是纤维长度偏短 Through analyzing the fiber quality in regional trials of cotton varieties in the Yellow River Basin, it was found that the regional distribution of cotton fiber quality in the Yellow River Basin is obviously different. Fiber length distribution of the general direction: Huaibei Plain sub-area, the North China Plain coastal sub-region of North China Plain sub-region of the Loess Plateau Asia. The areas of high specific intensity were the middle part of North China Plain and the eastern part of the Loess Plateau. The low value areas appeared in most of the subregion of Huaibei Plain and the southwestern part of the Loess Plateau. The micronaire value tends to decrease along the northwest of the southeastern part of the river basin. The overall fiber quality to the case of strong strand rope, high value areas for most of Hebei, Shandong and western central Jiangsu and northern regions; low value area has two parts: one is in southeastern Henan, southwestern and northern Anhui, the main reason is Thicker fibers, lower specific strength, the second is the Loess Plateau sub-region of the three original, Linfen area, the main reason is the shorter fiber length
