摘　　要：棉花是哈密区域的重要农产品经济作物,随着全球气候变暖,极端天气的出现对棉花品质带来了不确定性。通过统计哈密区域2014—2023年气象数据和棉花品质参数,运用Pearson相关系数评价棉花品质与气象条件之间的相关性。结果显示,棉花蕾期需要充足的热量来保障自身的生长,哈密区域过于充足的日照时数对棉花品质带来负面影响,无霜期天数对棉花品质呈现正相关,有效积温与棉花的平均长度、马克隆值A+B、断裂比强度和棉花颜色级呈现出正相关,大于等于35℃日数与平均长度和断裂比强度表现出正相关,与长度整齐度和棉花颜色级呈现出负相关。Cotton is an important agricultural and economic crop in the Hami region.With global warming,the emergence of extreme weather has brought uncertainty to the quality of cotton.By analyzing meteorological data and cotton quality parameters in the Hami region from 2014 to 2023,the Pearson correlation coefficient was used to evaluate the correlation between cotton quality and meteorological conditions.The results showed that cotton bud stage requires sufficient heat to ensure its own growth.Excessive sunshine hours in the Hami region have a negative impact on cotton quality.The number of days in the frost free period is positively correlated with cotton quality.The effective accumulated temperature is positively correlated with the average length,micronaire value A+B,fracture ratio intensity,and cotton color level.The number of days at or above 35℃is positively correlated with the average length and fracture ratio intensity,and negatively correlated with length uniformity and cotton color level.
