摘　　要：以鲜食秋大豆品种‘萧农秋艳’为试验材料,采用播种期为主区、种植密度为副区的裂区设计,以研究不同播种期和播种密度对鲜食秋大豆产量及农艺性状的影响。结果表明:不同播种期和播种密度对鲜食秋大豆的产量有极显著的影响,不同播种期对株高、分枝数、单株有效荚数、百荚重和产量等性状的差异显著,不同种植密度对单株有效荚数、百荚重和产量等性状的差异极显著;不同播种期和播种密度通过影响单株有效荚数、百荚重进而影响产量。播种密度低虽然能够提高单株生产力,但会降低群体产量。因此,从经济等效益综合考虑,在衢州地区,鲜食秋大豆‘萧农秋艳’的播种期以8月10日左右,密度以10000株/667 m^(2)为宜。In order to study the effects of different sowing dates and densities on yield and agronomic traits in autumn vegetable soybean variety’Xiaonongqiuyan’,a split-plot design was adopted with planting date as the main plot and planting density as the split plot.The results showed that different sowing dates and densities had significant effect on the yield,and there were significant differences in plant height,branch number,effective pod number per plant,100 pod weight and yield,etc.,with different sowing dates,while there were significant differences in effective pod number per plant,100 pod weight and yield etc.,with different sowing densities.The influence of different sowing dates and densities on yield was related to the effective pod number per plant and 100 pod weight.With the decrease of sowing density,productivity per plant increased but population yield decreased.Therefore,from the comprehensive consideration of economic and other benefits,the suitable sowing date of’Xiaonongqiuyan’in Quzhou area is about August 10 th,and the suitable density is 10000 plants/667 m^(2).
