摘  要：
4个矮生菜豆品种 (副处理 )在秋季分 5期播种 (主处理 ) ,采用 4次重复的裂区试验设计 ,研究播种期和品种对矮生菜豆结实能力的影响。试验结果表明 ,随着播种期的延迟 ,从播种到开花以及播种至采收所需时间逐渐缩短 ,而实际采收期反而随播种期延迟而延长。小区豆荚产量和豆荚数在播期间以及品种间均存在极显著差异 ,播期与品种的互作效应亦达到显著或极显著水平 ,其中豆荚产量和结荚数随播期延迟均呈现下降趋势 ,但品种间存在一定的差异。单株分枝数在 5个播期内 ,呈现先上升再下降的态势 ,而平均单荚重及荚长则均随播期的延迟而下降。

摘  要：
Based on the sprit-plot experiment on 4 dwarf bean cultivars sown on different dates in autumn, the effects of seeding date on their pod yields and pod-setting abilities were studied. The experiment were repeated for 4 times, in which the seeding date was designed as a main factor and cultivars a side factor. The experimental results showed that there were significant differences of pod yields and pod number between the different seeding dates and between different cultivars, and also there was a significant interaction between seeding dates and cultivars. It was found that the days between seeding～flowering and between seeding～pod harvesting decreased with the seeding date being put off, but the harvesting duration was prolonged. The pod yield and number of pods reduced with the seeding date being put off, though some differences existed among the four cultivars. Characters related to pod yield, such as number of branches, average pod weight and pod length, were also affected by both seeding date and cultivars. The average pod weight and pod length decreased with the seeding being put off, while the number of branches reached the highest value on the seeding date of Aug. 20 except the cultivar 'Provider'.
