| 摘 要： | 用早毛豆、夏大豆、特用豆和芽用豆类计18个大豆品种(系)为材料研究了不同播期对大豆生长和产量的影响.结果表明:播期对早毛豆各品种的全生育期无明显的影响,而其它类大豆品种的全生育期均随播期的延迟而缩短.除早毛豆外,大豆株高、单株分枝数、单株成英数和单株产量多随播期的延迟而降低;百粒重在35g以下的,播期对百粒重的影响不甚明显.

| Abstract: | Field experiment was conducted to investigate the effects of sowing date on growth characteristics and seed yield of soybean. Eighteen soybean cultivars including early vegetable soybean, summer soybean, special - end soybean and sprout-end soybean were used. The results showed that sowing date had no significant effects on growth duration of early vegetable soybean. However, the growth duration of other three soybean types was shortened, and the plant height, branches, pods and seed yield per plant was declined with the delayed sowing date except for early vegetable soybean. The effect of sowing date on 100 - seed weight was slight when 100 - seed weight was under 35 g. |
