摘　　要：以化诱5号为材料，研究了不同的播期对大豆产量性状的影响。结果表明，在6月4日-7月2日期间，播种越早，单株有效荚数、单株粒数和单株粒重越高；百粒重受播期影响较小，各播期间差异不显著；而荚粒数随播期的推迟则逐渐增多。在适宜播期内，播种越早，单株产量越高。The effect of different sowing time on yield characteristics of Huayou 5 was studied in this report. The result showed that sowing time between 4 June and 2 July, the mumber of pods, number of seeds per plant and weight of seeds per plant were decreased with the sowing time postpone; Sowing time had less influence on 100- seed-weight, there was no significant differences among each sowing time, but number of seeds per pod were increased as the sowing time postpone ; In the appropriate sowing time, earlier sowing could get a higher yield of per plant.
