以阿拉尔垦区为研究对象,分析比较该垦区2013—2015年4个主栽棉花品种纤维品质的差异。结果表明,不同品种间,纤维品质各等级所占比例存在明显的差异。新陆中62号的纤维长度和马克隆值表现最优,长度29 mm级占65.8%、马克隆值A级占23.8%。新陆中60号的纤维长度在26~29 mm级均有较大比例分布,且26 mm级的比例最高,比强度则表现最差,差级比例高达48.4%。新陆中37号和新陆中28号的纤维长度居中,马克隆值以前者较优;比强度强级比例以前者较多,后者则以差级比例较多。因此,棉纤维品质的不同指标在品种间差异较大,棉花品种选育及推广栽培更应注重棉花品种的品质特性。
Taking Alar reclamation area as the research object, the differences of fiber quality among the four main cultivated cotton varieties in the reclamation area from 2013 to 2015 were analyzed and compared. The results showed that there was a significant difference in the proportions of different grades among different varieties. Xinluzhong 62 showed the best fiber length and micronaire value, accounting for 65.8% of the 29 mm length and 23.8% of the micronaire A grade. Xinluzhong 60 had a large proportion of fiber length in the range of 26-29 mm, with the highest proportion of 26 mm, the worst of specific strength, and the difference of 48.4%. New Lu Zhong No. 37 and Xin Lu Zhong No. 28 had the longer fiber length, the former micronaire value was better; the former was stronger than the latter, while the latter was more differentiated. Therefore, the different indicators of cotton fiber quality vary greatly among cultivars. Cotton breeding and cultivation should pay more attention to the quality characteristics of cotton cultivars.
