摘　　要：为提高毕节辣椒产量,运用二次饱和D-最优设计方法,研究了定植密度(X1)、复合肥用量(X2)2个因素对毕节名优辣椒大方皱椒和金椒1号产量的影响。研究结果表明,线椒在定植密度为9 311株/667 m2,复合肥施用量为105.18 kg/667 m2时,干椒667 m2产量最大,达248.65 kg;朝天椒在定植密度为11 253株/667 m2,复合肥用量为114.22 kg/667 m2时,干椒667 m2产量最大,达246.30 kg。The quadratic saturated D-optimal design method was used to study the effect of planting density（X1） and compound fertilizer dosage（X2） on Bijie hot pepper cultivars.The results showed that the Xianjiao could achieve the highest yield when the planting density was 9 311 plant/667 m2 and the compound fertilizer dosage was 105.18 kg/667 m2,the peak output was 248.65 kg/667 m2.Differently,the highest yield of Chaotianjiao was 246.30 kg/667 m2 when the planting density was 11 253 plant/667 m2 and the compound fertilizer dosage was 114.22 kg/667 m2.
