In order to explore the effects of Chemical Regulations treatments on agronomic traits and yield for cotton the cotton yield, the correlation analysis and factor analysis for plant height, bolls number, leaves number, fruit branch number and boll weight were analyzed.The results showed that five agronomic traits had certain influence on the cotton yield, and the correlationship between the yield and the five agronomic traits of the height, bolls number, leaves number, fruit branch number, boll weight were not entirely consistent.In the D3 treatment, the five traits were highly significantly correlated with the yield.In each treatment, the structure and character of various factors where changed, the bolls number, branches number, boll weight had direct contribution to the cotton yield, whereas the biological traits factors have indirect effects, and D3 treatment was more efficient in promoting the cotton production.%探索不同化控方式对棉花农艺性状与产量的相关性影响.本试验对棉花产量及株高、铃数、叶片数、果枝数、单株铃重5个农艺性状进行相关分析和因子分析.分析表明5个农艺性状对棉花产量构成具有一定的影响,其各处理的株高、铃数、叶片数、果枝数、单铃重与产量的相关性并不完全一致,以D3的5个性状与产量关系最为密切,均呈现极显著关系.各处理能使不同因子的结构和性状发生一定变化,产量因子的铃数、果枝数、铃重对产量有直接的贡献,生物性状因子对产量有间接效应的影响,而D3可使因子内性状间的协调促进作用更为合理,有益于棉花产量的提高.
