| 摘 要： | 以17个不同类别的棉花品系为试验材料,采取不同时间收获籽棉,研究其衣分和纤维品质的变化趋势。结果表明:衣分以前期收获籽棉的最高,霜后花的最低;棉纤维长度受环境因素影响较小,比强度则以中前期收获的棉纤维较高,霜后花比强度明显下降,霜后花的棉纤维马克隆值均在4.0以下,棉纤维成熟度最差。

| Abstract: | With 17 different categories of cotton lines as experimental materials , the changing trends of lint percent and fiber quality of seed cotton were studied at different harvest time .The results showed that the lint percent was the highest in the seed cotton harvested earlier , but the lowest in the ones harvested after frost.Fiber length was less affected by environmental factors .Specific strength of fiber harvested in early -middle period was comparatively higher , while that harvested after frost decreased obviously .The Micronaire value of fiber harvested after frost was below 4.0, and the fiber maturity was the worst . |
