摘　　要：为了探讨苎麻新品种0501的高产优质综合配套栽培技术,以该品种为试验材料,采用二次正交旋转组合设计,研究了施肥和密度等4个因素对苎麻产量(Y1)和纤维支数(Y2)的影响,建立了优化数学模型,Y2=2071.17-41.43X1+28.32X2+88.81X3-67.48X12+52.91X32。根据回归方程模拟寻优,筛选出最佳措施与策略,当4个因子的编码值X1=l.682、X2=1.682、X3=-1.682、X4=1.682时,原麻理论产量(三季麻)可达最大值5722.6 kg/hm2;当氮肥施用量为978.3 kg/hm2,有机肥施用量为3006.9 kg/hm2,钾肥为1666.6 kg/hm2,密度为24885株/hm2时,原麻理论纤维支数可达最大值2417.84公支。New ramie variety 0501 was used in this research, in order to exploring me comprenensive technology for high yield and good quality. Orthogonal rotated combination design was used to study the effects of fertilization and density in ramie＇ s fiber fineness. The optimized mathematical model of fiber fineness and the management measure for ramie variety 0501：Y2=2071.17-41.43X1＋28.32X2＋88-81X3-67.48X12E＋52.91X23, the highest yield will reach 5722.6 kg/hm^2, When X1=1.682, X2=1.682, X3=-1.682, X,=1.682. When nitrogenous fertilizer was 978.3 kg/hm：, manure fertilizer was 3006.9 kg/hm2, potash fertilizer was 1666.6 kg/hm2, plant density was 24885 strain/hm2, the fiber fineness was higher than 2417.84 Nm.
