| 摘 要： | 选用两个不同类型的豌豆品种,同时进行分期播种。试验结果表明:随播期推迟,豌豆生育期缩短,产量下降。分枝量及发生部位与温度、日长密切相关。播期对产量的影响主要表现在单株结英数的变化。早熟品种适期播种的范围宽,晚熟品种则对播期要求严格。

| Abstract: | Two different types of pea varieties were selected and sown by stages at the same time. The results showed that the growth period of pea was shortened and the pea yield was decreased as the sowing time was delayed. The influence of sowing dates on pea yield was embodied mainly by the varia- tion of the pods per plant. The appropriate sowing dates for the early—maturing varieties were longer, and the late—maturing ones were limited for the sowing dates. |
