| 摘 要： | 2013年通过大豆品种郑7051不同播期、行距、株距种植对产量的影响试验,结果表明,大豆郑7051于6月11日与6月21日播种株高相当,7月1日播种株高明显降低。播种较早时,随着行株距减少,株高增高;播种较晚时,随着行株距减少,株高有增加趋势,以株距10 cm最高。单株粒数随播期推迟而减少;百粒重受播期影响较大,受密度的影响较小。温度对大豆产量影响较大,试验于6月11日、6月21日播种,均能取得高产,以行距40 cm,株距13.3 cm时产量最高;7月1日播种的产量较低。

| Abstract: | By analyzing the effect of different sowing dates, row and plant spacing on the yield of soybean cultivar Zheng 7051, it showed that plants sowed on 11 th and 21 st of June were similar in height, while the plant height sowed on 1st July was significantly lower. When soybean was sowed earlier, with the reduced row spacing, plant height increased; While plant height had an upward tendency and achieved the highest at row spacing of a 10 cm with later sowing. There was a decrease in seed number with the delay of sowing.The hundred-seed weight was affected more by sowing date than by plant spacing. Temperature had animportant influence on the yield, the plant sowed on 11 th or 21 st of June both achieved higher yield,especially with a 40 cm row spacing and 13.3 cm plant spacing. While the yield of soybean sowed on 1st July was lower. |
