摘要
为了客观评价影响皮棉品质的气候因素,采用GGE双标图,分析了黄河流域2013—2015年度早熟棉区试品种皮棉品质与气候因素的相关性。近几年的试验结果表明:棉纤维长度与花铃期总日照时间呈显著正相关,与8月总降水量稳定负相关。棉纤维细度与铃期降水量、7月上旬降水量相关性最为密切,呈显著负相关。棉纤维断裂比强度与花铃期平均气温、7月下旬平均气温呈显著正相关,与7月上旬降水量密切负相关。
In order to objectively evaluate the influene of climatic factors on lint yield,GGE biplot method was adopted to analyze the correlation of major climatic factors and lint quality of early maturing cotton varieties in cotton regional trials in the Yellow River Valley during 2013-2015.The results showed that there existed a significant positive correlation between cotton fiber length and time of sunshine in the flowering and boll stage,and a stable negative correlation between cotton fiber length and the total rainfall in August.The fiber fineness was most negatively related to the total rainfall in the flowering and boll stage and that in early July.Fiber strength was positively affected by the average temperature during the flowering and boll stage and late July,however negatively related to rainfall in early July.
