摘　　要：本文研究了棉花在充氮气、抽真空和自然环境储存条件下的品质变异规律。通过对棉花的马克隆值、反射率、黄度、长度、长度整齐度和强度6个关键指标,进行16个月的跟踪测试,利用机器学习和统计分析方法对数据进行处理分析,得出结论:在自然环境、充氮气和抽真空3种储存条件下,棉花的马克隆值、长度、整齐度、强度变化均在测量允许误差范围内,表明这3种储存条件下这些指标的变化无显著差异;3种储存条件下的反射率均呈现明显下降趋势,其中抽真空储存条件下的反射率下降速度相对充氮气和抽真空较慢;3种储存条件下的黄度值均随时间显著上升,充氮气储存条件下黄度的上升速度最快。本研究为棉花的储存方法提供了新的思路,并提供了数据支撑。This study investigates the quality variation patterns of cotton stored under nitrogen enrichment,vacuum,and natural environmental conditions.Six key indicators of cotton quality,including micronaire value,reffectance,yellowness,length,length uniformity,and strength,were tracked and tested over a period of 16 months.Data were processed and analyzed using machine learning and statistical analysis methods.The conclusion drawn is that under the three storage conditions:natural environment,ni-trogen enrichment and vacuum,the variations in the micronaire value,length,uniformity and strength of the cotton are all within the allowable measurement error range,indicating no significant differences in the changes of these indicators under the three storage conditions.The reflectance under all three storage conditions showed a clear downward trend,with the vacuum storage condition exhibiting a slower rate of decline compared to nitrogen enrichment and the natural environment.The yellowness values under all three storage conditions significantly increased over time,with the rate of increase being the fastest under nitrogen enrichment.This research provides new insights into cotton storage methods and offers data support.By deeply analyzing the variation patterns of quality indicators of cotton under the three storage conditions,this study is instructive for optimizing cotton storage technology.
