摘　　要：[目的]探索山西旱地条件下豇豆栽培的高产措施。[方法]以中豇1号为研究对象,选取密度、氮肥、磷肥和钾肥为试验因素,按照二次通用旋转组合设计统计分析方法建立回归模型,分析种植密度和不同肥料配比对中豇1号产量的影响。[结果]各因子对豇豆产量的影响达到显著水平,且变化趋势均呈开口向下的抛物线,影响顺序由高到低依次为K肥、P肥、N肥、密度;要获得1 875 kg/hm2的产量,种植密度、氮肥、磷肥和钾肥的最优取值范围为:种植密度为120 465～128 295株/hm2,施N 40.49～54.66 kg/hm2,施P2O542.92～56.24 kg/hm2,施K2O 57.91～65.93 kg/hm2。[结论]该研究为豇豆大面积种植提供理论依据。[Objective]To investigate the high-yield cowpea cultivation measures in the dryland in Shanxi Province.[Method]Cowpea variety Zhongjiang1was used as research material,and planting density,nitrogen,phosphate and potash were selected as4experimental factors,quadratic regression model was established in accordance with rotation design statistical analysis method,and the effects of different fertilizers and planting densities on cowpea yield were analyzed.[Result]Each factor had significant influence on cowpea yield,as demonstrated by a trend of opening downward parabola,and in an order of potash(K)>phosphate(P)>nitrogen(N)>density.To achieve a yield of1875kg/hm^2,the best combination of nitrogen and phosphate fertilizer,potash fertilizer and planting density were as follows:nitrogen40.49-54.66kg/hm^2,phosphate42.92-56.24kg/hm^2,potash57.91-65.93kg/hm^2,and the planting density of120465-128295plants/hm^2.[Conclusion]The study provides theoretical basis for large area plantmy of cowpea.
