摘　　要：为探讨大棚长豇豆春季高产优质制种技术,寻求大棚豇豆春季种子获得高产的最佳播种期和密度,以绵豇8号为试验材料,采用播期、密度二因素裂区试验设计,研究了不同播期和密度对豇豆制种产量的影响。结果表明,大棚豇豆春季制种产量随播期的推迟和密度的增大呈先升高后降低的趋势;随播期的推迟和密度的增加,单株荚数、单荚粒数先增加后降低,早播和迟播均不利于单株荚数、单荚粒数和百粒质量的提高,密度对百粒质量的影响不显著;A_(2)B_(3)(3月15日播种,密度为9000株/667 m^(2))是最适播期和种植密度处理组合,种子产量达154.98 kg/667 m^(2)。In order to explore the high yield and good quality seed production techniques of cowpea in greenhouse in spring,and find out the best sowing date and planting density of cowpea seed in spring,the field split-plot design with sowing date and density was used to study the effects of sowing date and planting density on yield of Mianjiang No.8.The results showed that the seed yield of cowpea in spring increased at first and then declined as the delay of sowing date and increase of planting density.With the delay of sowing date and increase of density,the pod number of a single plant and seed number of a single pod increased firstly and then decreased,and sowing too early or too late were not conducive to the increase of pod number of a single plant,seed number of a single pod and weight of 100 seeds.In addition,the effect of planting density on weight of 100 seeds was not significant.The optimum combination of sowing date and planting density was A_(2)B_(3)(sowing on 15 March with the density of 9000 plants/667 m^(2)),and the yield reached 154.98 kg/667 m^(2).
