摘　　要：采用手扯法测量纤维长度,研究了棉花不同品种的纤维长度差异及不同播期对纤维长度的影响。结果表明,不同品种的纤维长度存在显著差异,而播期对纤维长度没有显著影响,品种与播期的互作对纤维长度有显著影响;3个品种中以中棉所41-1的纤维最长,播种期DP99B选择2月11日、美抗Ⅱ选择2月11日、中棉所41-1选择3月22日可获得较长的纤维。Fiber was pulled straight by hand and then the affect of variety and sowing date on fiber length of cotton was studied. The results showed that both the variety and the reciprocity of variety and sowing date have an evident influence on fiber length, whereas sowing date has no remarkable influence on it. Among the three varieties tested, Zhongmiansuo41-1 has the longest fiber and to have a longer fiber, the sowing date of February llth of both DP99B Xuan and Meikang lI and March 22nd of Zhongmiansuo41-1 should be chosen.
