摘　　要：选用不同纤维品质类型棉花品种 ,采用分期播种的方法 ,研究棉纤维品质变化及与气象因子的关系。结果表明 :纤维各品质指标对各因子的反应不同 ,长度、整齐度和伸长率主要受品种遗传特性的影响 ,纤维比强度和马克隆值除受品种遗传特性影响外还明显受到气象因子的影响。就影响品质的气象因子而言 ,不同纤维性状主要受控因子是不同的 ,纤维长度和伸长率受铃期总日照时数影响较大 ;整齐度、比强度受铃期≥ 1 5℃活动积温影响较大 ;Based on the experiment with 4 different types of cotton varieties and 3 sowing-date,the changes of fiber quality under different meteorological conditions and correlation with meterological factor was studied.The result showed that different fiber quality character has different controlled factors.Fiber length,fiber uniformity and fiber elongation rate were most influenced by the hereditary trait of variety.Fiber strength and micron was affected not only by the hereditary trait of variety but also effected remarkably by meteorological factors.As far as the meteorological factors are concerned, the main meteorological factors which affected the different fiber quality characters are not the same.Fiber length and fiber alongation rate was affected mainly by the total sunshine time of cotton boll stage.Fiber uniformity and fiber strength is affected mainly by activity accumulated temperature (≥15℃) of cotton boll stage.Macron was mostly influenced by the highest temperature of cotton boll stage.
