采用夏大豆品系驻 94 1 4进行田间秋播试验 ,对其植株性状、生育期及产量结构等进行研究。结果表明 ,秋播夏大豆生育期 ( 95d)缩短 ,株高降低 ,主茎节数减少 ,百粒重和蛋白质含量 ( 48.7%)增加 ,籽粒产量2 868kg/ hm2 ,或毛豆荚 60 0 0～ 70 0 0 kg/ hm2。证明夏大豆秋播的可行性 ,在生产、科研等方面有广泛的应用前景 Autumn Sowing Experiment of Summer Soybean Line in 9414 was conducted to study its plant characters, growth period and yield structure. The results showed that the yield of autumn sowing summer soybean was shortened, the plant height was reduced, the number of main stems was reduced, the grain weight and protein content (48.7%) were increased, and the grain yield was 2 868 kg / hm2 or 600 000 pod, 70 0 0 kg / hm2. Prove the feasibility of autumn sowing of summer soybean in the production, research and other aspects of a wide range of applications
