摘要： 为了明确不同栽培因子对‘绥杂7 号’产量影响的综合效应，采用三因素二次通用旋转组合设计方法，建立了栽培密度、施肥量、播种日期与粒用高粱‘绥杂7 号’产量之间的效应模型，经DPS统计软件检验，二次回归模型拟合度较好。建立的回归模型为：Y=8218.18312- 446.78324X12- 287.68422X22-567.34494X32。试验结果表明：密度、施肥量、播期3 因子对产量的增产作用依次为播期>密度>施肥量，对密度与肥料、密度与播期、肥料与播期之间的交互效应分析得出：以上两两因子之间存在一定程度的正交互效应。模型经计算机模拟寻优，得到’绥杂7 号’获得7330 kg/hm2以上产量的栽培因子组合方案为栽培密度17.154~18.846万株/hm2，施肥量为211.8~150.7 kg/hm2，播种日期为5月7号—5月12号。

Abstract: In order to investigate the comprehensive effect of different cultivation factors on‘suiza No.7’ sorghum, with three factors quadratic current rotation revolving design, the models were established on the effects of density, fertilizer amount and seed-date on yield of‘Suiza No.7’Sorghum. According to the testing results of DPS, the quadratic regression model had better simulation effect. The mathematical model was: Y= 8218.18312-446.78324X12-287.68422X22-567.34494X32. The results showed that the influencing order of three factors on yield was sowing time >planting density>fertilizer. Two-factor interaction analysis showed that there was a positive interaction between sowing time and planting density, planting density and fertilizer, sowing time and fertilizer to some extent. By computer simulating, the cultivation combination to obtain seed yield above 7330 kg/hm2 for‘Suiza No.7’was being planted at 7th to 12th May with planting density of 17.154- 18.846×104 plants/km2 and fertilizer rate of 211.8-150.7 kg/hm2.
