大麻纤维产量构成因素的相关分析初报

Preliminary Study about Correlation Analysis of Yield Component Factors of Hemp Fiber

为促进黑龙江省纤维大麻产业的发展,选用大麻纤维产量(Y)与株高(X1)、茎粗(X2)、单位面积收获株数(X3)、干茎制成率(X4)、全麻率(X5)等因素建立数学模型,其相关方程为Y=12 595.10-1.997 X1-227.931 X2-1.158 X3-128.704 X4+94.927 X5;全麻产量与株高,茎粗呈负相关,与单位面积收获株数呈显著正相关,与干茎制成率呈正相关,与全麻率呈极显著正相关。

In order to promote industry development of fiber hemp ,a mathematical model was established by fac-tors closely related including fiber yield（Y）of hemp ,plant height（X1 ） ,stem diameter（X2 ） ,plant number of unit area（X3 ） ,pull rate of dry stems （X4 ） ,total fiber content （X5 ）and so on .The correlation equation was Y =12 595 .10-1 .997X1 -227 .931X2 -1 .158X3 -128 .704X4 ＋94 .927X5 .Fiber yield was negatively correlated with plant height and stem diameter ,also correlated with plant number of unit area and pull rate of dry stems positively ,as well as positively correlated with total fiber content significantly .
