| 摘 要： | 三年试验结果表明,大豆籽粒增重过程呈S型曲线,这种变化特点可利用三次多项式描述。大豆的这种鼓粒特点是由本身干物质流动特性决定的,而与生态环境变化无关。但是,播种日期早,鼓粒速度较慢,持续期长;温度高,鼓粒速度快,持续期短。籽粒含水量下降过程与百粒重增加过程正相反。

| Abstract: | Experinmental results during three years indicated increases in soybean seed weight were at S type curve,and expressed by w=a bt ct2 dt3 The characteristics of soybean seedfilling was decided by its dry matter flowing,and not related to ecological conditions.However,earlier planting had slower race and longer duration of seedfilling; higher temperture had faster rale and shorter duration of seedfilling.Dry weight of 100 seed increased during decreasing water content of soybean seed. |

| Keywords: | Glycine max (L.) rate of seedfillingl seedfilling duration |
