摘要
依托国家纤维检验局发布的棉花公正检验数据,比较分析新疆生产建设兵团等行距和宽窄行两种种植模式下机采棉的品质和经济性。数据统计分析结果显示:在棉花品质方面,两种种植模式下的机采棉纤维品质在长度、长度整齐度、反射率、黄色深度、马克隆值、断裂比强度等方面均有显著性差异,且在颜色级、反射率、黄色深度、长度、断裂比强度方面等行距棉花优于宽窄行棉花,在长度整齐度、马克隆分档方面宽窄行要优于等行距;在经济性方面,等行距种植模式要好于宽窄行种植模式,主要是因为在棉花颜色级和长度级上的差异造成的经济性差异。
The differences of cotton quality between single rows and twin rows were analyzed.The data are from China Fibre Inspection Bureau.In the matter of fiber quality,the results indicated that the cotton quality in the two planting patterns had significant difference in fibre length,length uniformity index,reflectance,yellowness,micronaire and fibre strength.In the matter of color grade,reflectance,yellowness,fibre length,and fibre strength,single rows were better than twin rows.In the matter of length uniformity index and micronaire grade,twin rows were better than single rows.In the matter of economic,the single rows were better than the twin rows due to the differences in color grade and fibre length grade.
