| 摘 要： | 利用四元二次回归旋转组合设计方法，在秋播条件下研究苦荞黔苦3号籽粒产量与播种量及氯、磷、钾肥施用量之间的关系。通过试验，建立了籽粒产量与播种量、氮、磷、钾肥施用量的回归数学模型；经计算机模拟试验和优化选择，提出了秋播苦荞苦3号籽粒产量≥2500kg／hm2的综合农艺措施为：播种量33．41～41．76kg／hm2、施N量39．60～53.01kg／hm2、施P2O5量175．50～214．50kg／hm2、施K2O量57．96—68．72kg／hm2。

| Abstract: | Using four-factor five-level quadratic regression universal rotary combination design,we studied relations between grain yield of Qian-bitter-buckwheat No. 3 and seeding rate,application rate of nitrogen phosphorus potassium when planted in autumn. We also set up mathematics model. By simulated test and optimality selection,we put forward cultivation techniques programme （buckwheat grain yield ≥2 500 kg/ha） ：seeding rate is 33.41 ~ 41.76 kg/ha, N-application rate is 39.60 -53.01 kg/ha, P2O5- application rate is 175.50 -214.50 kg/ha, K2O-application rate is 57.96 -68.72 kg/ha. |
