本文运用旋转设计进一步发展的双重组合试验设计，建立黑龙江省关于降水、有机质、氮、磷、钾肥及有机肥的玉米产量模型，探讨了双重组合试验设计在建模时用可控因素去挂接不可控因素的应用，对模型进行了检验和频数分析，提出玉米产量大子3000公斤的高产在艺措施．
In this paper, a dual combination experimental design for further development of rotary design was used to establish a corn yield model for precipitation, organic matter, nitrogen, phosphorus, potassium and organic fertilizer in Heilongjiang Province. The application of uncontrollable factors, the model was tested and frequency analysis, put forward a large corn production of 3000 kg of high-yield arts measures.
