采用五因子二次回归正交旋转组合设计，研究了冀西北地区播种期、密度、氮肥、磷肥、钾肥对食用向日葵产量的影响。试验单因子效应结果表明：播种期和氮肥在五因子中作用较大。试验两因子互作效应结果表明：氮肥和磷肥、磷肥和钾肥、密度和钾肥3对互作效应较大。食用向日葵高产栽培技术的最佳综合农艺组合为：播种期6月6～7日，密度33195～34305株/hm2，氮肥117.9～127.8 kg/hm2，磷肥51.2～52.8 kg/hm2，钾肥108.3～113.4 kg/hm2，适宜的 N︰P2O5︰K2O 平均为1︰0.41︰0.91。采用该组合试验示范，较当地传统种植模式增产5.8%～9.5%。

The effects of sowing time, density, and nitrogen, phosphate and potassium fertilizers on the yield of confectionary sunflowers were studied adopting five-factor quadratic regression orthogonal rotation combination design in northwest of Hebei. The results of experimental single factor effect showed that the effects of sowing time and nitrogen fertilizer were higher in the five factors. The results of the interaction effect of two experiment factors showed that the interaction effects between the nitrogen fertilizer and phosphate fertilizer, between the phosphate fertilizer and potassium fertilizer, and between the density and potassium fertilizer are higher. The optimal comprehensive agronomic combination in the confectionary sunflower high-yield cultivation technology is as follows: the sewing time is June 6th to June 7th, the density is 33 195 to 34 305 plants/hm2, the nitrogen fertilizer is 117.9~127.8 kg/hm2, the phosphate fertilizer is 51.2~52.8 kg/hm2, the potassium fertil-izer is 108.3~113.4 kg/hm2, and the proper average ratio of N︰P2O5︰K2O is 1︰0.21︰0.91. By adopting the combination in the experimental demonstration, the yield was 5.8%~9.5% higher than that of the local traditional planting pattern.
