棉花纤维品质受环境因素的影响较大。不同棉区由于生态条件的差异,棉纤维品质的表现也有所不同。根据本研究结果,江苏省淮北地区各试点棉花的纤维品质,一般差于江淮之间和沿江各试点。淮北地区纤维品质较差的原因,主要与常年8～10月份棉铃充实期间气温较低有关。但这一地区4～6月份气温较高,日照较多;8～10月份降水较少,日照也较多,对棉花早发、结铃、吐絮较为有利。因此,我们认为江苏淮北地区是适于发展中支纱用棉的高产地区。而发展高支纱用棉,则以江淮之间和沿江较为有利。不同棉区都有其比较有利于棉铃发育、纤维品质较好的一段开花结铃期,以此可以作为棉花优质高产栽培调节生育期的依据。初步看出棉纤维强度主要受铃期内积温和夜间平均温度的共同影响。
Cotton fiber quality is greatly affected by environmental factors. Different cotton areas due to ecological differences in the conditions of the performance of cotton fiber is also different. According to the results of this study, the fiber quality of each pilot cotton in Huaibei region of Jiangsu Province is generally worse than that of the pilot projects between JAC and Yangtze River. The reason for the poor fiber quality in Huaibei is mainly related to the lower temperature during the cotton boll enrichment from August to October in the perennial. However, the temperature in this area is relatively high from April to June, with more sunshine. There is less precipitation in August and October and more sunshine, which is beneficial to cotton bolls, boll bolting and bolting. Therefore, we think that the Huaibei area of Jiangsu is a high-yield area suitable for developing medium-count yarn. The development of high count yarn with cotton, then between the Jianghuai and along the river is more favorable. In different cotton areas, there is a period of flowering and boll opening which is more conducive to cotton boll development and better fiber quality, which can be used as the basis for regulating the growth period of cotton with high yield and good quality. It is initially concluded that the strength of cotton fiber is mainly affected by the accumulation of accumulated temperature and the mean night temperature during the boll period.
