以本地主栽大豆品种北丰9号为材料，研究了东宁县第三积温条件下，不同播期对大豆物候期、产量及主要农艺性状的影响。结果表明：在一定播期范围内，播种越晚，温度越高，出苗越快；适时播种比过早过晚播期产量、单株粒数、百粒重均高，说明适时播种意义重大。

Effects of different sowing dates on phenological period, yield and the main agronomic traits of cultivar Beifeng No.9 were studied in Dongning country, the third accumulated temperature region. The results showed that late sowing and higher temperature lead to quick seedlings emergence. The yield, seed number per plant, and 100-seed weight under appropriate sowing date was higher than the sowing earlier or later, respectively. Therefore, sowing in good time was of significance for soybean production.
