播种期对ＳＧ２５９和Ｐｒｏｖｉｄｅｒ两个矮生菜豆品种的物候期、结实能力、种子产量和品质均有明显的影响。从播种（出苗）到始花所需的时间春播较秋播长；秋播时，则随着播种期的推迟而延长；从开花到种子采收所需的时间是秋季较春季长。春播的单株分枝数较秋季多，而单株结荚数则是以７月２５日前后播种的较多。ＳＧ２５９的小区种子产量以７月下旬播种的较高，而Ｐｒｏｖｉｄｅｒ则是以３月３日和７月２５日播种的较高；种子品质以７月下旬播种较为理想。结果表明，杭州地区矮生菜豆种子的生产适宜播期在７月２５日前后。
The sowing date had a significant effect on the phenophase, grain-bearing ability, seed yield and quality of SG259 and Provider two dwarf bean varieties. The sowing time (seeding) to the beginning of the flowering was longer than the sowing time in autumn; the autumn sowing time was prolonged with the delay of sowing time; the time from flowering to seed harvesting was longer in autumn than in spring. The number of branches per plant in spring was more than that in autumn, while the number of pods per plant was sown more before and after July 25. The plot of SG259 plotted seeding was higher in late July, while that of Provider was higher on March 3 and July 25; the seeding quality was better seeding in late July. The results showed that the suitable sowing dates of dwarf beans in Hangzhou were sowed around July 25.
