摘　　要：从沂豆12的生长习性和黄淮地区的自然优势入手,通过选用良种、肥水管理、病虫草害防治、适期收获等技术措施,阐述黄淮地区模式化夏大豆沂豆12高产栽培技术,并分析大豆高产栽培效益,以期为大豆种植管理提供参考。In order to explore the suitable cultivation measures of Yunyan 116 in Bijie tobacco area,the effects of different nitrogen application rates,planting density and leaf number on the output value of Yunyan 116 were studied by three factor quadratic regression orthogonal rotation combination design.Single factor effect analysis showed that within the experimental range,the output value of flue-cured tobacco increased first and then decreased with the increase of nitrogen application rate,planting density and the number of leaves left.Nitrogen application rate was the primary factor affecting the output value,followed by the number of leaves left and planting density.The two factor interaction analysis showed that the interaction effect between nitrogen application rate and leaf number had the greatest and negative effect on the output value.The output value was simulated and optimized.The results showed that when the nitrogen application rate was 5.87-6.91 kg/667 m 2,the transplanting density was 1047-1153 plants/667 m 2 and the number of leaves left was 19-21 pieces/plant,the target output value of more than 2300 yuan/667 m 2 could be obtained,which was the optimal cultivation combination of Yunyan 116 in Bijie area.
