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 =12595.10-1.997 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。
為促進黑龍江省纖維大痳產業的髮展,選用大痳纖維產量(Y )與株高(X1)、莖粗(X2)、單位麵積收穫株數(X3)、榦莖製成率(X4)、全痳率(X5)等因素建立數學模型,其相關方程為 Y =12595.10-1.997 X1-227.931 X2-1.158 X3-128.704 X4+94.927 X5;全痳產量與株高,莖粗呈負相關,與單位麵積收穫株數呈顯著正相關,與榦莖製成率呈正相關,與全痳率呈極顯著正相關。

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 .
