| 摘 要： | 通过研究不同播期对大豆生长发育进程的影响,发现大豆的生育期随着播种日期的延迟而缩短,大豆播期与生育期长短呈显著相关;不同播期对大豆的株高、主茎出叶数、叶面积指数均有很大的影响,随着播期的延迟,株高、主茎出叶数、叶面积指数最大值均呈下降趋势。

Effects of Different Sowing Dates on Development Process of Soybean |
| |
| Abstract: | Effects of different sowing dates on development process of soybean were studied.The results showed that the growth period of soybean shortened as the sowing date delayed,and the sowing date significantly correlated with the growth period.Different sowing dates greatly affected plant height,the number of stem leaves,and leaf area index of soybean.With the sowing date delayed,the maximal date of plant height,the number of stem leaves,leaf area index of soybean decreased. |

| Keywords: | soybean different sowing dates growth period growth and development effect |
