摘要
为了明确几种不同的分析方法在气象因子对棉花纤维影响分析中异同,于2008~2009年通过多目标综合值评定分析原理、关联度分析、逐步回归分析、偏相关分析等原理进行不同年份气象因子与纤维品质定量分析。结果表明:几种分析方法对气象因子与纤维品质关系的分析趋势基本一致,温度、光照时间是影响纤维品质的主导因子,降水量是限制因子,温度高、光照时间长,适度降水量有利于纤维成熟、麦克隆值、纤维长度、比强度同时增加,纤维品质达到最优。
In this paper,the various analysis methods were applied to study the meteorological factors affected the cotton fiber quality,and evaluate target comprehensive value by the relational grade analysis,stepwise regression analysis and partial correlation analysis from 2008 to 2009.The results showed that the various methods based on the different theory gained the similar results.The temperature and sunshine time were critical factors that had effects on fiber quality and the precipitation was a limited factor.Under the condition of higher temperature,long sunshine time and moderate precipitation,it was beneficial for fiber maturation and suited for increasing the micronare-value,fiber length and specific strength in order to get the optimal fiber quality.
