| 摘 要： | 大豆百粒重受鼓粒后气象条件的影响，由此引起的产量波动约占大豆总产量的３．１％。百粒重的大小主要取决于粒重的增长速度和鼓粒时间的长短。各气象要素综合作用决定了大豆百粒重的大小。

| Abstract: | Soybean 100 seed weight is influenced by the meteorological condition on seed filling stage. The causative yield fluctuation is 3.1% of the total output. The weight of 100 seeds dapends upon mainly on its increase rate and its continuous time. The increase rate of 100 seed weight is mainly influenced by the highest temperature, the duration of sunshine and the rain capacity at farmer stage. At later stage it is mainly influenced by temperature diurnal variation and the duration of sunshine. The continuous time of 100 seeds weight are mainly influenced by the temperature condition of seed filling stage. The synthetic effect of each meteorological element decides the weight of 100 seeds. |
