摘　　要：使用新疆农八师垦区棉花产量资料、棉花物候观测资料和气象资料,运用多项式方法分离出气候产量,并采用线性回归及线性相关方法,探讨了棉花不同发育期热量资源变化对棉花产量的影响。结果表明,新疆农八师垦区在棉花各个生长期热量资源变化对气候产量均显著相关。当≥0℃积温每变化100℃·d,播种—出苗期、出苗—开花期、开花—吐絮期及吐絮期分别影响棉花产量6.6、3.5、3.9、6.2个百分点。各个发育期棉花减产的热量指标为播种—出苗期≥0℃积温≤235℃·d、出苗—开花期≤1465℃·d、开花—吐絮期≤1620℃·d、吐絮期≤475℃·d;当全生育期≥0℃积温≤3630℃·d、≥10℃积温≤3350℃·d时为棉花减产指标。该结果可为新疆农八师垦区棉花栽培生产提高技术管理水平提供理论参考。In order to explore the influence of changes in thermal resources on cotton yield in different development phases in the Rec⁃lamation Area of the Eighth Division of Xinjiang Production and Construction Corps,in this study,using cotton yield data,cotton phe⁃nological observation data and meteorological data in the Eighth Division,the climatic yield was separated by the polynomial method,and linear regression and linear correlation methods were used.The results showed that the changes of thermal resources in different development phases of cotton were significantly correlated to the climatic yield in Reclamation Area of the Eighth Division of Xinjiang Production and Construction Corps.When the accumulated temperature changed 100℃·d in case that the temperature was≥0℃,6.6%cotton yield was influenced in the sowing-seedling phase,3.5%cotton yield was influenced in the seedling-blooming phase,3.9%yield was influenced in the blooming-boll opening phase and 6.2%yield was influenced in the boll opening phase.The thermal index for cotton production in each development phase was that≥0℃accumulated temperature≤235℃·d in the sowing-seedling phase,≤1465℃·d in the seedling-blooming phase,≤1620℃·d in the blooming-boll opening phase;≤475℃·d in the boll opening phase.In the whole growing season,the cotton reduction index was≥0℃accumulated temperature≤3630℃·d and≥10℃accumu⁃lated temperature≤3350℃·d.These results could provide theoretical reference to improve the technical management level of cotton cultivation and production in Reclamation Area of the Eighth Division of Xinjiang Production and Construction Corps.
